This Keto Peanut Butter Mousse is a creamy, low-carb dessert perfect for anyone following a ketogenic diet. Made with mascarpone, smooth peanut butter, and lightly sweetened with powdered sweetener, this mousse is rich and fluffy thanks to whipped heavy cream. It’s a simple no-bake recipe that comes together quickly and can be served with a drizzle of peanut butter or crumbled low-carb biscuits for extra texture and flavor.

Ingredients

Scale

Main Ingredients

  • 1 cup mascarpone (or cream cheese, cold) (240g)
  • 1/4 cup powdered sweetener (40g) (use 1/3 cup / 60g for a sweeter mousse)
  • 3 tbsp smooth peanut butter (55g)
  • 1 cup heavy cream (cold) (240g)
  • 1/2 tsp vanilla extract
  • Pinch sea salt (if your peanut butter is unsalted)

Instructions

  1. Combine base ingredients: Add the mascarpone or cream cheese, powdered sweetener, smooth peanut butter, and vanilla extract into a mixing bowl. If your peanut butter is unsalted, also add a pinch of sea salt. Use an electric mixer to blend all ingredients together until smooth and fully combined.
  2. Whip the cream: In a separate clean bowl, whip the cold heavy cream with a mixer until it reaches just below stiff peaks. This will help create the mousse’s light, airy texture.
  3. Fold the cream into the base: Gently fold the whipped cream into the peanut butter mixture. Use a spatula to carefully combine until the mixture is smooth and uniform in texture without deflating the whipped cream.
  4. Serve and garnish: Spoon or pipe the mousse into serving glasses. Optionally, top with crumbled low-carb biscuits and a drizzle of peanut butter for added texture and flavor. Chill if desired before serving.

Notes

  • You can substitute mascarpone with cream cheese if preferred, but keep it cold to achieve a smooth texture.
  • Adjust the sweetness by increasing the powdered sweetener to 1/3 cup (60g) if you want a sweeter dessert.
  • The mousse is best served chilled but can be enjoyed immediately after preparation.
  • For a crunchy topping, use your favorite low-carb biscuit crumbles or chopped nuts.
  • This recipe is naturally gluten-free and low-carb, making it perfect for keto diets.
