Creamy Greek Yogurt Peanut Butter Mousse Recipe

Recipe Highlights

• 15 grams of protein per serving: the Greek yogurt base provides a satisfying protein boost that helps the mousse feel substantial and filling.
• Six ingredients: made from common pantry staples so it’s easy to pull together.
• Ready in ten minutes: no baking or stove time required—just mix and serve, or chill briefly if you prefer a firmer texture.
• Peanut butter cup flavor: finish with chocolate or chocolate shavings to get that classic peanut butter cup experience.

After my Greek Yogurt Chocolate Mousse gained attention, I wanted to create a peanut butter version that kept the same light, mousse-like texture while delivering that unmistakable peanut butter cup flavor. The recipe is straightforward: thick Greek yogurt, powdered peanut butter or regular peanut butter, maple syrup for sweetness, vanilla, and a pinch of salt. A small amount of instant vanilla pudding mix is optional and boosts the mousse’s thickness and loft.

I tested this mousse with both powdered peanut butter and creamy peanut butter. Powdered peanut butter yields a lighter, slightly higher-protein option with fewer calories, while regular peanut butter produces a richer, more decadent result. Both versions are delicious; choose based on your texture and nutrition preferences.

The optional vanilla pudding mix adds extra structure and makes the mousse fluffier, but you don’t need it for a great result. Because this recipe requires only mixing—no cooking or baking—you can prepare it as a quick snack, a make-ahead dessert, or even a protein-forward breakfast.

Key Ingredients

Greek Yogurt: I recommend 2% (or full-fat) Greek yogurt for extra creaminess, but any thick Greek yogurt will work. The thickness of the yogurt is important to achieve a mousse-like texture.

Peanut Butter: You can use powdered peanut butter (reconstituted in the final mixture) or traditional creamy peanut butter. Powdered peanut butter produces a lighter texture with more protein per serving, while regular peanut butter creates a richer flavor and mouthfeel. Measure about 1/4 cup powdered peanut butter or 3 tablespoons of regular peanut butter.

Maple Syrup: Adds natural sweetness and pairs well with peanut butter. Use the amount listed in the recipe to balance sweetness without overpowering the peanut flavor.

Vanilla and Salt: Vanilla extract brightens the overall flavor; a tiny pinch of salt enhances the peanut notes. If your peanut butter is already salted, you can omit the added salt.

Instant Vanilla Pudding Mix (Optional): This ingredient is optional but useful if you want an extra thick, fluffy mousse. You can use a sugar-free pudding mix if you prefer.

How to Make High-Protein Peanut Butter Mousse

Recipe overview: Combine the ingredients in one bowl, whisk until smooth, divide into portions, and top as desired. The full ingredient amounts and step-by-step instructions follow in the recipe card below.

Step 1: Place the Greek yogurt, powdered peanut butter (or creamy peanut butter), maple syrup, vanilla extract, optional vanilla pudding mix, and a pinch of salt into a mixing bowl.

Step 2: Whisk vigorously until the mixture is completely smooth and lump-free. Whisking incorporates air, giving a light mousse texture—use a hand whisk rather than stirring to get the best result.

Step 3: Divide the mousse into four jars or bowls. Top with crushed peanuts, chocolate shavings, or melted dark chocolate for a chocolate shell. Serve immediately, or chill briefly if you used pudding mix for a firmer set.

Jess’s Tips

• Choose 2% or full fat Greek yogurt: it makes a noticeably creamier mousse than fat-free versions.
• Whisk, don’t just stir: a whisk traps air and helps achieve that silky, mousse-like lift.
• Adjust salt to taste: skip extra salt if your peanut butter is salted.
• Chill if using pudding mix: ten minutes in the fridge improves the final texture when you include instant pudding.
• Add the chocolate shell just before serving: melted chocolate sets quickly on cold mousse, giving the best crisp break.
