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 / 55g smooth peanut butter
  • 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 cold mascarpone or cream cheese, powdered sweetener, smooth peanut butter, and vanilla extract into a mixing bowl. If using unsalted peanut butter, add a pinch of sea salt. Use an electric mixer to blend all ingredients until smooth and well combined.
  2. Whip the Cream: In a separate clean bowl, whip the cold heavy cream until it reaches just below stiff peaks. This means the cream is thickened and holds soft peaks but is still pliable to fold.
  3. Fold Cream into Peanut Butter Mix: Gently fold the whipped cream into the peanut butter mixture until the mousse is fully combined and smooth. Avoid overmixing to keep the mousse light and airy.
  4. Serve: 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 before serving if desired.

Notes

  • Ensure all dairy ingredients are cold to achieve the best whipped texture.
  • Adjust the sweetener amount to suit your taste preference; using 1/3 cup (60g) results in a sweeter mousse.
  • Use smooth peanut butter for the creamiest consistency.
  • Optionally garnish with low-carb biscuit crumbs and extra peanut butter drizzle for contrast and decoration.
  • Keep the mousse refrigerated until serving as it contains cream and cream cheese which need to stay cold.
