How To Make Peanut Butter Mousse
Step 1. Mix the wet ingredients. In a mixing bowl, combine the peanut butter, Mascarpone cheese, and vanilla extract. Beat until smooth, about 1 minute.
Step 2. Fold in the sugar and whipped topping. Add the powdered sugar and beat until well incorporated, stirring down the sides until blended. Gently fold in the whipped topping until smooth.
Step 3. Assemble and serve. Spoon into parfait glasses, or use a pastry bag and a large decorating tip to swirl it into dessert glasses. Serve immediately, or chill until ready to serve.
It’s important to make sure you’re using no-stir natural peanut butter for this recipe that does not contain sugar as it can throw off the texture and level of sweetness.
Don’t like the ingredients in Cool Whip? Try using a container of Truwhip instead.
To make sugar-free peanut butter mousse. Use sugar-free cool whip and replace the powdered sugar with Swerve Powdered Sugar or Powdered Monkfruit Sweetener. Taste as you go, as the level of sweetness is different when compared to traditional powdered sugar. These ingredient swaps make this dessert suitable for a keto or low-carb lifestyle.
If you happen to have leftovers, use this peanut butter mousse as a topping for cupcakes or as a delicious cake frosting.
If you want to lighten up the calories, even more, you can substitute reduced-fat cream cheese for the mascarpone cheese. However, I love the flavor of the mascarpone cheese in this recipe!
There are so many ways to serve peanut butter mousse. Pipe it into a dessert glass and use the following topping ideas to make it your own:
- Chocolate Sauce
- Chopped Peanuts, Pecans or Walnuts
- Whipped Cream
- Fresh Fruit
- Summer Berry Sauce
- Chocolate Chips or White Chocolate Chips
- Butterscotch Sauce
- Chocolate Sprinkles
- A dusting of Cocoa Powder
Storing & Freezing
Storing: Peanut butter mousse can be stored in a pastry bag or airtight container for up to one week before serving.
Freezing: Since this dessert is whipped, it is not recommended for freezing as it may lose its texture and airy light nature.
When building a mousse recipe, you’ll need to keep the following in mind: a flavor focus, a binder, an aerator, and seasonings. This peanut butter mousse checks all the boxes!
Truwhip is a less processed version of Cool Whip that contains less gums, preservatives and binding agents. It can be found in most specialty health food stores.
You can experiment with almond butter, cashew butter or even sunflower seed butter in this recipe, however I have not tested the proper ingredient ratios for other nut butters.
