  • 3 oz cream cheese, softened
  • ¾ cup heavy cream, cold
  • ¼ cup peanut butter, no sugar **
  • 2 tablespoons peanut butter powder **
  • 4 tablespoons Swerve sweetener
  • dark chocolate (optional) **


How to make the peanut butter mousse.

  1. Add all the ingredients to a mixing bowl and with a hand mixer cream together until the mousse is thick and creamy. 

  2. Spoon or pipe into dessert cups and refrigerate until ready to eat.

How to make the chocolate hearts.

  1. Melt ½ of a low carb chocolate bar in the microwave for 30 seconds. Take it out and stir until it's all melted. 

  2. On a wax paper covered cookie sheet, take a small spoon and place a small circle of chocolate on the paper. Take your spoon and move the chocolate up to make the top of the heart. Then take the spoon and drag the chocolate at the bottom down to a point to form a heart. Do this with all of the chocolate. This should make 4 or 5 hearts.

  3. ** I used Aldi Simply Nature peanut butter and peanut butter powder. Both are just peanuts and no added sugar. I also used Moser's 85% dark chocolate bars as they are low in carbs. Each small bar has 6g net carbs.
