  1. Add the mascarpone or cream cheese, sweetener, peanut butter and vanilla to a mixing bowl. Mix with an electric mixer to combine. If your peanut butter is unsalted, also add a pinch of sea salt
  2. In a clean bowl, whip the cream until just below stiff peaks.
  3. Fold the whipped cream through the peanut butter mix until combined and smooth. Pipe or spoon into a glass and top with optional crumbled low carb biscuit of choice and a drizzle of peanut butter.

Notes

  • 3g net carbs per portion. Makes 6 portions of 90g each.
  • I topped my mousse with a drizzle of peanut butter and crumbled keto ginger cookies. 
  • Store in the fridge for up to 6 days or freeze for up to 3 months. 
  • If using cream cheese, use a good quality thick one like Philadelphia.
