Peanut Butter Souffle, often shortened to PB Souffle or PB Soufflé, is an indica-leaning dessert cultivar bred by the California-based team at Atlas Seed. As its name suggests, the strain evokes bakery-counter decadence with a creamy, nutty profile wrapped in silky, dense resin. Consumers who gravitate toward Do-Si-Dos, Mendo Breath, and other confectionary lines will find a familiar harmony of doughy sweetness and earthy depth. It is a modern, high-terpene, high-potency pick designed for flavor-first sessions and evening wind-downs.
Atlas Seed developed PB Souffle in the early 2020s, a period when North American markets began favoring terpene-forward dessert genetics with consistent production traits. The breeder’s hallmark has been uniformity and vigor, with selections meant to perform reliably in both indoor and greenhouse settings. In the case of PB Souffle, Atlas aimed to lock in a soft, velvet mouthfeel while preserving a compact indica structure. The result is a cultivar that pleases the nose and palate as much as it pleases growers who want strong bag appeal and dependable yields.
Independent tasting notes align with the strain’s bakery theme. A Leafly Canada feature that grouped Peanut Butter Souffle among strains similar to Do-Si-Dos described it succinctly: “Like a creamy nutty cake, Peanut Butter Souffle has a velvety smooth taste that’ll leave you licking your lips in anticipation of the next toke.” In addition, Leafly’s data-driven similarity engine has listed PB Souffle alongside terpene- and effect-adjacent picks such as Unicorn Tears, reinforcing the cultivar’s place in the relaxing, dessert-forward lane. That combination of crowd-pleasing flavor and chill effects is a big reason PB Souffle has found an audience quickly.
While many dessert strains compete on novelty alone, PB Souffle stands out for how comprehensively it delivers on aroma, flavor, and mouthfeel. The smoke is soft and coating, a quality that is as much about terpene synergy as it is about how the flower was dried and cured. Consumers consistently report that the flavor holds from the first draw to the last, an indicator of robust terpene content. That sensory consistency is part of why PB Souffle has become a go-to for enthusiasts who care as much about taste as about potency.
History and Breeding Origins
Atlas Seed is known in the U.S. craft and commercial space for selecting vigorous, uniform lines that still retain the boutique flavors buyers demand. During the early 2020s, Atlas released a run of dessert-leaning cultivars targeting the then surging demand for nutty, cakey terpene profiles. PB Souffle fit that moment perfectly by balancing the creamy, confectionary notes with a grounded, earthy base. Its indica-leaning structure also catered to growers seeking compact plants that stack well under artificial light.
The breeder has not publicly released the precise parental cross for Peanut Butter Souffle, a practice that is common when protecting proprietary lines. What is documented is that PB Souffle leans heavily indica, with short internodes, broad leaflets, and pronounced lateral branching. Those features often correlate with Mendo Breath and Do-Si-Dos families, though such connections should be treated as educated guesses rather than confirmed fact. Reports of phenotypes that throw purple hues in cooler finishes further hint at dessert lineage overlaps without confirming exact parents.
As PB Souffle rolled out through dispensaries and breeder menus, it began showing up in data-driven similarity graphs. Leafly’s recommendation engine, which clusters cultivars by shared dominant terpenes and user-reported effects, places PB Souffle near Unicorn Tears and Holy Grail in some lineups. This does not assert parentage but supports what many tasters perceive: a calm, euphoric, full-bodied experience carried by a creamy-nutty terpene blend. In a market with thousands of named cuts, statistical proximity can be a helpful compass.
In short, PB Souffle is the product of modern selection priorities that prize consistency and dessert-forward flavor. Its history is less about a single famous cross and more about breeder goals around structure, resin, and terpene persistence. Atlas Seed’s strategy helped PB Souffle gain traction in both boutique and scaled environments, especially where stable performance and high bag appeal matter. The cultivar’s momentum continues as more growers learn how reliably it translates care into quality.
Genetic Lineage and Indica Dominance
Peanut Butter Souffle’s exact lineage remains undisclosed by Atlas Seed, but its morphological and sensory traits point to a predominantly indica background. Plants tend to grow squat with medium to heavy lateral branching, producing dense colas with modest internodal spacing. Such architecture is typical of indica-dominant cultivars selected for indoor production where canopy control is essential. The growth pattern also helps concentrate resin and terpenes in shorter runways, boosting aromatic intensity at harvest.
The name and flavor suggest ties to the broader peanut butter and cake families that emerged from Do-Si-Dos and Mendo Breath influences. While it is not accurate to list specific parents without confirmation, the nutty pastry profile often correlates with β-caryophyllene, limonene, and myrcene combinations found in those lineages. Leafly’s editorial note placing PB Souffle alongside Do-Si-Dos-adjacent picks reinforces that sensory kinship. This is a link of resemblance, not a declaration of genetic identity.
In practice, the indica dominance translates to a flowering window that typically lands between eight and nine weeks for most phenotypes. Stretch is moderate, commonly in the 1.2x to 1.6x range when flipped from veg, which simplifies trellis planning. The calyx development is robust, commonly yielding a favorable calyx-to-leaf ratio that reduces trim labor post-harvest. Together, these features make PB Souffle attractive in both small-batch craft settings and scaled canopy rooms.
Because Atlas Seed focuses on uniformity, growers can expect less phenotypic drift than in older clone-only dessert strains. That said, subtle differences can occur, with some plants leaning more toward a doughy vanilla batter and others toward toasted nut and cocoa. These micro-variations tend to track with slight shifts in dominant terpenes, not wholesale differences in potency or structure. The overall package remains decidedly indica-forward in both garden behavior and user experience.
Appearance and Bud Structure
PB Souffle presents dense, medium-sized buds shaped like rounded cones or slightly oval eggs. Colas stack neatly, with bracts swelling into tight clusters that make the flowers look frosted from stem to tip. The trichome coverage is high, often appearing like a dusting of powdered sugar in top light. Under magnification, the heads are bulbous and plentiful, a sign of resin-rich potential ideal for both flower and extraction markets.
A mature plant often shows forest to olive green as the base color, with streaks of lavender and deep plum in cool-finishing rooms. Hairs appear in shades of copper to tangerine, adding contrast that is accentuated once the sugar leaves are trimmed tightly. The calyxes are plump and layered, giving the bud a slightly soufflé-like rise that suits the name. Because the leaves are not overly abundant on well-grown flowers, PB Souffle trims into a clean, easy-to-bag shape.
Growers frequently notice that the buds maintain structural integrity during drying and curing when handled correctly. Proper conditions keep the exterior lightly crisp while preserving interior pliability, reducing shatter risk and terpene loss. The trait is valuable for retailers who need consistent shelf appeal across jars and pre-rolls. Consumers appreciate the tactile experience of a bud that breaks down into sticky, resinous fragments without crumbling.
Aroma: From Doughy Batter to Toasted Nuts
Open a jar of PB Souffle and the room fills with a bakery-like plume that blends raw cookie dough, toasted peanuts, and a hint of cocoa nib. At first sniff, many pick up a warm, buttery base reminiscent of cake batter just out of the mixing bowl. Secondary notes bring a light earthiness and a delicate spice, akin to crushed pepper over roasted nuts. This progression can read as comforting and nostalgic to dessert strain fans.
As the flower breaks apart, sharper top notes emerge, often citrusy bright while still wrapped in a creamy halo. Some lots lean toward orange oil and lemon zest, signaling limonene’s hand in the bouquet. Others emphasize a deeper herbaceous line, with myrcene and humulene smoothing the edges into a more grounded, woody aroma. The aromatic journey is nuanced yet coherent, moving from sweet dough to nutty spice with a citrus lift.
Post-grind, the aromatics intensify, and the nutty facet becomes more pronounced alongside chocolaty undertones. The sweetness stays balanced rather than cloying, which helps the nose retain complexity session after session. That balance is what separates PB Souffle from one-note bakery strains that can smell sweet but lack depth. It is a dessert profile built for repeat enjoyment rather than novelty-only appeal.
Flavor Profile: Velvety, Nutty, and Dessert-Like
Flavor is where Peanut Butter Souffle earns its name and reputation, delivering a soft, velvety smoke from first draw to finish. The inhale brings a creamy sweetness that recalls vanilla batter and almond cream. As the vapor settles, toasted peanut, light cocoa, and a touch of brown sugar come forward. The exhale is smooth and buttery, with a faint pepper warmth that never tips into harshness.
External tasting notes echo this decadent experience. A Leafly feature on strains similar to Do-Si-Dos in Canada called PB Souffle “like a creamy nutty cake,” praising the “velvety smooth taste” that invites another pull. That assessment tracks with user reviews that emphasize mouth-coating richness and low throat bite. It is an indulgent profile that holds its character even at lower temperatures in a vaporizer.
For those who care about flavor integrity across consumption methods, PB Souffle performs well in both glass and dry herb vapes. At 180–190°C, vapes often emphasize vanilla cream and peanut, while combustion adds a deeper roasted nut and cocoa layer. The aftertaste lingers pleasantly, with many reporting a pastry-like finish for several minutes post-session. Taste stability across devices is a sign of sufficient terpene concentration and a balanced chemotype.
Cannabinoid Profile and Potency
Peanut Butter Souffle is typically a high-THC, low-CBD cultivar consistent with modern indica-leaning dessert strains. While numbers vary by phenotype and cultivation, most growers and buyers can expect THC commonly in the 20–26% range by dry weight. CBD is usually below 1%, with many lots testing under 0.3%. Total cannabinoids often land between 22–28% when minor cannabinoids are included, a level that supports robust, long-lasting effects.
Among minor cannabinoids, CBGA and CBG frequently appear in measurable amounts. CBGA can register in the 0.5–1.5% range, and CBG in the 0.2–1.0% range, depending on harvest timing and genetic expression. Trace THCV or CBC may be present below 0.5%, with significant variability between producers. These minor components, while small, can influence subjective effects and entourage interactions with terpenes.
Potency alone does not define the experience, but PB Souffle’s numbers are meaningful for dose planning. Many users report strong effects at 5–10 mg of inhaled THC, which can be reached with as little as 0.05–0.10 g of flower at 20% THC per session. Beginners should start low and go slow, spacing inhalations by several minutes to gauge onset. Experienced consumers often find one to three bowls sufficient for a full evening arc.
For concentrate makers, PB Souffle’s resin-rich glands and dense trichome fields translate to respectable returns. Hydrocarbon or rosin presses can see yields in the 18–25% range from well-grown, terpene-heavy flower. The high total cannabinoid content boosts potency while the terpene suite preserves the dessert-forward nose. These attributes make PB Souffle a dual-purpose cultivar suitable for both jar appeal and extract programs.
Terpene Profile and Chemotype
The dominant terpenes in PB Souffle often include β-caryophyllene, limonene, and myrcene, which align with its nutty, creamy, and citrus-lifted dessert character. β-caryophyllene can center the profile with peppery warmth and contributes to CB2 receptor activity. Limonene supplies the bright, zesty lift in the top notes and is associated with mood-elevating effects in user reports. Myrcene brings a plush, herbaceous body that many associate with couch-friendly relaxation.
Supporting terpenes commonly reported include humulene, linalool, and ocimene in trace to moderate amounts. Humulene adds woody, slightly bitter depth that reins in sweetness. Linalool may contribute floral-lavender tones and has been studied for calming properties in aromatherapy contexts. Ocimene can flash a sweet herbal fruitiness that rounds out the inhale and exhale.
Quantitatively, total terpene content in dialed-in PB Souffle can reach 1.5–3.0% by weight, a range consistent with premium dessert cultivars. β-caryophyllene often lands between 0.4–0.9%, limonene between 0.3–0.8%, and myrcene between 0.2–0.6%. Secondary terpenes typically appear at 0.05–0.3% each, though environment and harvest timing can shift the ratios. Terpene expression tends to be strongest when plants are finished with stable temperatures and careful drying.
Leafly’s science-driven similarity mapping that places PB Souffle near Unicorn Tears suggests chemotype overlap like caryophyllene-limonene primacy. This clustering helps explain why PB Souffle’s flavor remains silky rather than sugary sharp, and why the effects feel both uplifting and body-centered. The chemotype offers a cohesive sensory arc where top, middle, and base notes are integrated. That harmony is what gives PB Souffle its pastry-like completeness in the jar and in the bowl.
Experiential Effects and Use Cases
PB Souffle’s effects are classically indica-leaning with a composed, euphoric center. The onset typically arrives within 2–5 minutes after inhalation, beginning as a soft facial and ocular relaxation. A contented mood usually follows, with users describing a buffered, warm outlook that sidesteps racy edges. The body effects gather in the shoulders and lower back, easing residual tension from the day.
As the session unfolds, PB Souffle tends to deepen into a cozy, couch-friendly calm without necessarily forcing sleep. Many report a focus on sensory enjoyment like music, film, or conversation at a slower pace. Appetite stimulation can be moderate to strong, which some see as a benefit during late dinners or post-work wind-downs. The overall arc often lasts 2–4 hours depending on dose and tolerance.
User feedback and similarity mapping to strains like Unicorn Tears suggest a balance of bliss and ease rather than heavy sedation at modest doses. However, larger amounts can certainly tip the experience toward drowsiness, especially in low-stimulus settings. Those sensitive to potent indica effects should meter doses carefully and consider timing sessions after key tasks are complete. Hydration and light snacks can help pace the experience comfortably.
PB Souffle is well-suited for late afternoon and evening use, creative brainstorming with a relaxed tempo, or social hangs where a calm vibe is desired. Gamers and film lovers often praise how it reduces fidgetiness and heightens sensory texture. Comedown tends to be gentle, with fewer reports of grogginess compared to heavier knockout cultivars. This makes PB Souffle a versatile pick across a wide range of low-intensity activities.
Potential Medical Applications
While clinical research on specific cannabis cultivars is limited, PB Souffle’s indica-leaning chemotype and dominant terpenes suggest several potential therapeutic niches. The caryophyllene-limonene-myrcene triad is commonly associated with relaxation, mood lift, and physical ease in observational reports. Users dealing with situational stress, general tension, or discomfort after intense activity may find value in its body-forward calm. The dessert-like profile can also make adherence easier for those sensitive to sharp or piney flavors.
In anecdotal accounts, PB Souffle may aid sleep onset when taken in moderate to higher doses about an hour before bed. Myrcene’s sedative reputation and caryophyllene’s CB2 activity are often cited in this context, though robust clinical evidence remains limited. The balanced uplift from limonene can help soften mood during the evening transition, potentially supporting a smoother pre-sleep routine. As always, individual responses vary and timing matters.
For appetite support, indica-forward cultivars are often reported to increase hunger, and PB Souffle fits that pattern. This effect may be useful for those experiencing appetite suppression tied to stress or certain treatments, though patients should consult healthcare providers for individualized advice. Pain relief reports tend to center on mild to moderate musculoskeletal discomfort, with relaxation reducing perceived intensity. This may be aided by complementary strategies like heat therapy or stretching.
Consumers with sensitivity to anxiety from high-THC sativas sometimes prefer indica-leaning options like PB Souffle to reduce jittery edges. Still, THC can exacerbate anxiety in some individuals, so careful dosing and set-and-setting are important. Start with low doses, give time for onset, and consider vaporization temperatures that emphasize calming terpenes. Medical outcomes should be tracked in a journal with dose, time, and effects to identify personal patterns.
Cultivation Guide: Indoors, Greenhouse, and Outdoors
Peanut Butter Souffle tends to be a cooperative indica-leaning plant that rewards disciplined environment control. Indoors, it thrives in 22–26°C daytime temperatures during veg and 20–24°C during flower, with night drops of 2–4°C. Aim for relative humidity around 60–65% in early veg, 50–55% in late veg, 45–50% in early flower, and 40–45% in late flower. These targets align with a VPD of roughly 0.8–1.2 kPa in veg and 1.2–1.6 kPa in flower for healthy transpiration.
Expect a moderate stretch of 1.2x–1.6x after the flip, which is easy to manage with a single trellis layer for support. Topping once or twice in veg encourages an even canopy and reduces cola weight concentration that can cause stem flop late in flower. Low-stress training can widen the plant without stressing its thick, indica stems. The cultivar’s natural density benefits from light defoliation at day 21 and day 42 of flower to improve airflow.
PB Souffle typically flowers in 56–63 days, with some phenotypes happiest around day 60. For high-quality flower, watch trichomes rather than the calendar, targeting a window where most glands are cloudy with 5–15% amber. Pulling a bit earlier can preserve brighter citrus top notes, while a slightly later harvest deepens the nutty-chocolaty undertones. Avoid letting amber exceed 20% if you want to sidestep a heavy couchlock profile.
Lighting intensity of 600–900 µmol/m²/s PPFD in veg and 900–1100 µmol/m²/s PPFD in flower is a strong baseline under LED fixtures. CO2 supplementation at 800–1200 ppm can boost growth and yield if temperature, humidity, and light are optimized. Keep air movement gentle but constant to discourage microclimates that invite powdery mildew in dense canopies. Oscillating fans above and below the canopy are helpful for a plant of this structure.
In coco or soilless systems, start veg feeds around 1.2–1.6 EC and ramp to 1.8–2.2 EC through peak flower, watching tips to avoid burn. In living soil, rely on top-dressed amendments and teas, ensuring adequate calcium and magnesium to support thick bract development. PB Souffle responds well to sulfur availability for terpene synthesis, so consider sulfate forms at moderate levels. Maintain root-zone pH at 5.8–6.2 for hydro/coco and 6.3–6.7 for soil to optimize nutrient uptake.
Water management is key because dense buds can be susceptible to botrytis if RH spikes late in flower. Aim for complete wet-dry cycles in coco, with frequent small irrigations during peak uptake to stabilize EC. In soil, water slowly to saturation and allow 15–20% runoff in containers to avoid salt buildup. Use moisture meters or pot weight checks to standardize irrigation timing across a room.
Yield potential is strong for a dessert cultivar, with indoor harvests commonly in the 450–600 g/m² range under 12/12 with experienced hands. Greenhouse runs with extended veg and CO2 can exceed 60 g/ft² when dialed in, particularly with double trellis support. Outdoor plants in favorable climates can reach 0.6–1.2 kg per plant in 30–50 gallon containers. Actual results are highly dependent on environment, feed, and phenotype selection.
For greenhouse and outdoor cultivation, select sites with ample airflow and morning sun to rapidly dry dew. In coastal or humid regions, proactive IPM is essential, including weekly scouting and rotating biologicals such as Bacillus subtilis and Bacillus amyloliquefaciens. Predatory mites like Amblyseius swirskii can help with thrips and whitefly pressure, while lacewings target aphids. Botanical oils at low rates can be used in veg but should be avoided on flowering resin to protect terpenes and avoid residue.
Prune lower interior growth during early flower to reduce humidity pockets and redirect energy to top colas. A single mainline or manifold can work, but many growers prefer a natural bush with selective topping to leverage the cultivar’s lateral vigor. Finishing outdoor harvests before prolonged fall rains is wise, typically mid to late October at mid-latitudes for an eight- to nine-week flower. If late-season moisture is unavoidable, consider rain covers, increased spacing, and dehumidification in greenhouse bays.
Post-harvest, a gentle dry preserves PB Souffle’s velvety flavor. Target 15–20°C and 55–60% RH with minimal airflow directly on the flowers, drying for 10–14 days until small stems snap cleanly. Aim for a final moisture content near 10–12% and water activity between 0.55–0.65 to balance shelf life and terpene preservation. Cure in airtight containers, burping daily for the first week and then weekly for 4–8 weeks; extended cures often enhance the nutty-cocoa finish.
When preparing for market, a tight hand trim shows off the frosted calyxes and copper pistils that characterize the look. Keep bulk product cold-stored when possible, under 15°C and in darkness, to slow terpene volatilization. Nitrogen-flushed packaging and terpene-preserving liners can further maintain quality for 60–120 days. Always label batches with harvest date and storage conditions to maintain QA consistency across drops.
For extraction, choose harvest windows that maximize cloudy trichomes to capture terpene intensity without excessive degradation. Fresh frozen can be a strong option for live resin or rosin, preserving citrus-lifted top notes alongside the creamy base. Dry-cured material suited for hash should be handled minimally to avoid rupturing trichome heads before sieving. Expect concentrates that mirror the flower’s profile: smooth, nutty, and dessert-forward with a calming finish.
