Peanut Butter Mousse is a smooth and creamy treat that will be every peanut butter lover’s dream dessert! It is full of peanut butter flavor and just melts in your mouth with its velvety texture. Plus, it can be whipped up in about 5 minutes with just four ingredients that you probably already have on hand! I also have a Chocolate Mousse you will love.

Ingredients & Substitutions

Heavy Whipping Cream: Heavy whipping cream, or heavy cream, is a liquid that is 36-40% fat. You cannot use milk in this recipe.

Cream Cheese: Be sure the cream cheese is at room temperature before starting the recipe.

Confectioners’ sugar: Confectioners’ sugar, or powdered sugar, helps stabilize the mousse as well as give it a smooth texture.

Peanut Butter: For all of that flavor, use a half cup of creamy peanut butter.

How to Serve Peanut Butter Mousse

There are a variety of ways to serve and present homemade peanut butter mousse. Some ideas include:

  • In individual cups or ramekins: This is a classic presentation that allows each person to have their own portion of mousse. You can garnish the top with a dollop of whipped cream or some chocolate curls. Or, top with some nuts for a little bit of crunch to each bite.
  • Serve in a large bowl: For a dinner party or any gathering, consider preparing a single large bowl of mousse. You can either portion the mousse into individual servings or let your guests serve themselves. This is a convenient and elegant option that can be enjoyed by everyone.
  • Make a parfait: Layer the mousse with ingredients such as crumbled cookies or chopped nuts in a clear glass.
  • Use it as a filling: Fill a cake or cupcakes with this creamy peanut butter mousse.

How to Store Peanut Butter Mousse

Store peanut butter mousse in an airtight container in the refrigerator. This recipe will make about 2 1/2 cups of mousse and will last up to a week. It will be really thick when sitting in the refrigerator for a few days; let it sit out at room temperature for a few minutes before serving. For longer storage, freeze the mousse, covered, for up to 6 months. When ready to enjoy, let it thaw in the refrigerator overnight.

  1. I love that it says “will last a week” I made this amazingness and took it to work to share. I came home with an empty container the same day. I made a double batch even because it sounded so yummy! It was INCREDIBLE!

    Just a curiosity. Why do you mix the sugar with the peanut butter and cream cheese verses into the whipped cream?

  2. I just made this recipe, besides the hiccup of not having a hand mixer, it worked wonderfully! I just moved the whipped cream into a different bowl, and did the peanut butter mixture in the stand mixer. Then slowly added the cream back into the stand mixer. It came out great. I topped a cheese cake with it, can’t wait to serve it in 2 days!

  3. I’m going to make this recipe but I’m wondering if after the peanut butter mousse chills in the refrigerator I wonder if you could put chocolate hard shell on top so that it tastes like a Reese’s peanut butter cup
