Ingredients

Dairy: Go for full-fat cream cheese and heavy whipping cream for the richest flavor and fluffiest texture.

Peanut Butter: If using natural peanut butter, be sure to stir it thoroughly to incorporate the oil back into the peanut butter.

Sweetener: Any granular or powdered form of a keto-approved sweetener like Monk fruit, or Stevia works in this recipe. Brown sugar Swerve adds more depth of flavor than regular Swerve will.

Variations

  • Peanut butter mousse has the perfect flavor base for toppings! Sugar-free chocolate chips, low-carb chopped peanut butter cups, or fresh blueberries are fun and colorful toppings.
  • Layer mousse between two homemade keto peanut butter cookies and freeze for a decadent frozen dessert.
  • Use other keto-friendly nut butter varieties like almond butter, cashew butter, or any kind that is free of added sugars.

How to Make Peanut Butter Mousse

  1. Blend cream cheese and peanut butter until smooth. Set aside.
  2. Whip remaining ingredients (except peanuts) until stiff peaks form.
  3. Gently fold the whipped cream into the peanut butter mixture and refrigerate until ready to serve (recipe below).
  4. Garnish with chopped peanuts, if desired.

Tips for Success

  • To bend quickly, let cream cheese come to room temperature before using in Step 1.
  • Chill the heavy cream for the best whipped results.
  • To keep the mousse extra fluffy, gently fold the whipped cream mixture into the cream cheese mixture. Portion mousse into small cups with lids for a workday pick-me-up.

Storage Solutions

Keep mousse covered in the refrigerator for up to 3 days or freeze portions in zippered bags and enjoy as a frozen dessert or let it thaw in the refrigerator before serving.
