Peanut Butter Coffee: The PB Latte Trend, Protein Coffee Boom, Recipes, and Best Brands

Peanut butter coffee sounds like a novelty, the kind of food mashup that goes viral for a week and then disappears. But it has not disappeared. The PB latte has been appearing on independent café menus since at least 2015, gained significant social media traction by 2020, and by 2023 had become a staple of the protein coffee category, a segment of the canned and packaged beverage market that has grown faster than almost any other functional coffee subcategory. Ready-to-drink protein coffee brands like OWYN, Fairlife, and Core Power have collectively reached hundreds of millions of dollars in annual US sales, and peanut butter-flavoured options are consistently among their top sellers. This is not a trend that peaked. It is a permanent addition to the coffee landscape, driven by the intersection of two very large consumer behaviours: habitual coffee drinking and habitual protein supplementation.

Why Peanut Butter and Coffee Work Together

The flavour compatibility of peanut butter and coffee is not accidental. Both share a set of roasted, nutty, slightly bitter flavour compounds that developed through Maillard reaction chemistry during their respective processing. Coffee beans are roasted at temperatures between 180°C and 240°C, developing hundreds of flavour compounds including pyrazines, which contribute nutty and roasted notes. Peanuts are roasted at similar temperatures (typically 160°C to 204°C for commercial roasting), developing 2,5-dimethylpyrazine and other shared aromatic compounds that create genuine olfactory resonance with coffee aromas.

The fat content of peanut butter (approximately 16 grams of fat per 2-tablespoon serving, about 50 percent monounsaturated) also serves a functional purpose in coffee drinks. Fat carries fat-soluble flavour compounds and creates a coating mouthfeel that softens coffee's bitterness and extends the perception of sweetness and body. This is the same principle behind bulletproof coffee (butter or MCT oil in coffee) and the broader tradition of dairy fat in coffee, but with the added dimension of peanut butter's distinct flavour. The combination produces a drink that is simultaneously rich, filling, caffeinated, and protein-forward without the artificial sweetness or chalky texture that can make protein shakes unappealing.

The Home PB Latte: Three Core Recipes

Making a peanut butter latte at home requires either a blender (for the smoothest result) or a milk frother capable of emulsifying the peanut butter with a liquid base. Standard peanut butter does not dissolve in hot coffee, so emulsification is essential to avoid a greasy, separated drink.

The Classic PB Latte (Blender Method): Brew 2 shots of espresso or 120 ml of strong drip coffee. Combine in a blender with 240 ml of steamed or hot milk (whole milk or oat milk works well), 1 tablespoon of smooth natural peanut butter, 1 teaspoon of honey or maple syrup, and a pinch of salt. Blend on high for 20 to 30 seconds until fully emulsified and foamy. Pour into a pre-warmed mug. The result is a smooth, creamy drink with a pronounced peanut butter flavour and a latte-like texture. Total protein: approximately 12 to 15 grams using whole milk and natural peanut butter.

The Iced PB Cold Brew (No Blender Required): Combine 180 ml of cold brew concentrate with 120 ml of milk (dairy or plant-based), 1 tablespoon of peanut butter powder (PB2 or similar defatted peanut butter powder, which dissolves more readily than full-fat peanut butter), and sweetener to taste. Shake vigorously in a sealed jar or cocktail shaker until the powder is fully incorporated. Pour over ice. This method works without a blender because peanut butter powder is water-dispersible. Total protein: approximately 8 to 12 grams depending on milk choice.

The Protein PB Smoothie Coffee: Blend 180 ml of cold brew or cooled espresso with 1 scoop of vanilla or unflavoured whey or plant-based protein powder (approximately 20 to 25 grams protein), 1 tablespoon of peanut butter, 120 ml of milk, a frozen banana (optional, for sweetness and texture), and ice. This is a meal-replacement version that delivers 30 to 40 grams of protein, making it genuinely useful as a post-workout breakfast drink. The banana version adds approximately 100 calories and significant potassium.

Peanut Butter Powder: The Category Enabler

The mainstream growth of peanut butter coffee owes much to the development of defatted peanut butter powder as a widely available consumer product. PB2, produced by Bell Plantation and introduced to the US market in 2007, is made by pressing most of the fat out of roasted peanuts and then grinding the remaining solids into a fine powder. The resulting product has approximately 85 percent fewer calories from fat than conventional peanut butter (45 calories per 2-tablespoon serving versus approximately 190 calories for conventional peanut butter), retains a substantial portion of the peanut flavour, and dissolves in liquids without the emulsification difficulty of whole peanut butter.

PB2 had approximately $50 million in annual US retail sales by 2018 and has since been joined by competing products from Jif (Jif Powder), Planters, store brands, and numerous smaller producers. The powder format is now available in most major US grocery chains in the natural foods and protein supplement sections. For coffee applications, peanut butter powder is a more practical ingredient than conventional peanut butter because it can be stirred into cold or room-temperature liquids without blending equipment, making it suitable for workplace or travel preparation.

Ready-to-Drink Protein Coffee: The Brand Landscape

The ready-to-drink (RTD) protein coffee market has grown dramatically since 2018. Key brands in the peanut butter or peanut butter-adjacent category include:

• OWYN (Only What You Need): A plant-based protein drink brand that has offered coffee flavours including mocha and has reformulated multiple times to increase protein content. Available at Whole Foods, Target, and online. Approximately 20 grams of protein per bottle.
• Fairlife Nutrition Plan: While not specifically peanut butter-flavoured, Fairlife's core chocolate and vanilla protein shakes (30 grams protein, ultrafiltered milk) are frequently combined with coffee by consumers, and the brand has collaborated on coffee-flavoured variants. Available at most major US grocery chains.
• Muscle Milk Coffee House: CytoSport's coffee-protein drink line, available in café latte and mocha flavours with 20 grams of protein per serving. Peanut butter flavour has appeared in limited seasonal releases.
• Chobani Coffee Creamer: Not a protein drink per se, but Chobani's peanut butter flavoured coffee creamers (introduced around 2022) brought the peanut butter-coffee combination into the creamer category, available at Walmart, Costco, and major grocery chains.
• Peanut Butter & Co. Cold Brew: The specialty peanut butter brand entered the RTD coffee market with limited-run peanut butter cold brew products sold through specialty grocery channels.

The segment's growth is driven by converging trends: the rise of high-protein diets (keto, paleo, and general high-protein weight management frameworks), the decline of traditional breakfast eating occasions replaced by liquid breakfast, and the premiumisation of the RTD beverage category. NielsenIQ data from 2023 showed RTD coffee with protein claims growing at approximately 15 percent annually, outpacing conventional RTD coffee at roughly 6 percent growth.

Café Menu Versions: What Specialty Shops Are Doing

Independent cafés and small chains have been more creative with peanut butter coffee than the RTD market. Some notable menu approaches:

The "Elvis Latte," named after Elvis Presley's famous peanut butter and banana sandwich preference, combines espresso, steamed milk, peanut butter syrup (a commercially available flavour syrup sold by Monin, Torani, and other foodservice syrup brands), and banana flavouring. It has appeared on menus in Nashville, Memphis, and across the US South with particular frequency. The Monin Peanut Butter Syrup (750 ml, approximately $12 at restaurant supply retailers) is the most common commercial ingredient enabling cafés to add peanut butter flavour without the emulsification challenges of whole peanut butter.

Higher-end cafés have experimented with house-made peanut butter syrups using natural peanut butter cooked with water and sugar into a thin, filterable syrup, then strained to remove solids. The result is a clean peanut flavour without the fat separation that makes whole peanut butter problematic in espresso drinks. This approach requires kitchen capacity but produces a more nuanced flavour than commercial syrups.

Nutritional Considerations

A home PB latte made with 2 tablespoons of natural peanut butter, 240 ml of whole milk, and 2 espresso shots contains approximately 300 to 330 calories, 14 to 16 grams of protein, 18 to 20 grams of fat (predominantly monounsaturated from peanut butter), and 120 to 130 mg of caffeine. This is a genuinely substantive breakfast drink. Substituting oat milk reduces the protein content by approximately 5 grams but reduces saturated fat. Using peanut butter powder instead of whole peanut butter reduces total fat by approximately 12 grams and calorie count to approximately 180 to 200 calories.

People with peanut allergies cannot consume peanut butter coffee and should note that café versions may involve shared equipment. Almond butter and sunflower seed butter are common substitutions that work similarly in the recipes described above, though their flavour profiles are less immediately compatible with coffee's roasted notes than peanut butter's pyrazine overlap.

The peanut butter coffee trend has consolidated because it actually works on multiple dimensions simultaneously: it tastes good, it delivers genuine nutritional utility, it photographs well, and it fits naturally into the daily routine of the large population that already makes coffee and already supplements protein intake. When a food trend survives long enough to move from TikTok to grocery shelves to commercial syrup catalogues to café menus, it has stopped being a trend and become a category.
