Ingredients & Substitutions
Here I explain the best ingredients for this keto peanut butter mousse recipe, what each one does in the recipe, and substitution options. For measurements, see the recipe card.
Heavy Cream – Whipping the cream makes the mousse light and fluffy! You can substitute coconut cream, but the recipe would still have dairy, because it has mascarpone in it. Peanut Butter – Gives this mousse a nutty flavor. You could use other nut butters such as almond butter, as long as they contain no added sugar. Besti Powdered Monk Fruit Allulose Blend – If you need to use a different keto sugar substitute, I recommend powdered allulose. Granulated sweeteners, or even powdered sweeteners that contain erythritol (which is most brands of monk fruit and stevia), can lead to a gritty texture. Mascarpone Cheese – Makes the mousse so rich and creamy. If you can’t find store-bought, you can make homemade mascarpone cheese or use cream cheese instead. Warm to room temperature so that it blends in smoothly. Sugar Free Chocolate Sauce – Optional, for a sweet topping. You could also used chopped peanuts and sugar-free chocolate shavings, as shown in the photos.

Variations
Add different ingredients to this keto peanut butter mousse recipe to make it even better! Here are a few ideas: You want soft peaks, not stiff peaks. Soft peaks will form trails, but are not super stiff. If you hold your mixer up, the peaks should curve over. To keep your mousse fluffy, use a folding motion. This ensures that you don’t break down the whipped cream.
Keto Chocolate Peanut Butter Mousse – Melt sugar-free chocolate chips in the microwave in 30 second intervals and add to your peanut butter and cheese mixture. Works with milk chocolate chips and white chocolate chips, too! Alternatively, add 1-2 tablespoons of cocoa powder to the peanut butter mixture at the same time as powderd Besti. You could also crush up some homemade peanut butter cups! Add fruit – Swirl in cooked and pureed fruit of your choice after folding in whipped cream. Keto fruits such as raspberries or strawberries work well with the peanut butter flavor. Alternatively, add fruit on top as a garnish. Use extracts – Add hazelnut, mint, or vanilla extract to the cream after whipping. Make a nut-free version – Use sunflower seed butter instead of peanut butter.
