I adore all things peanut butter, and this peanut butter mousse is pretty high on my list. It’s so wonderfully creamy and delicious! You get big peanut butter flavor here that’s pretty much irresistible to peanut butter lovers.

Cream cheese – Let this come to room temperature before mixing. Use full-fat cream cheese that comes in blocks.
Confectioners’ sugar – For a smooth texture, sift the sugar. This is also labeled as powdered sugar or 10X sugar.
Peanut butter – I recommend using regular creamy peanut butter for the best results.
Heavy cream – Use heavy cream or heavy whipping cream.
Vanilla extract

Can I Use Another Nut Butter to Make This Mousse?

Sure! Almond butter, cashew butter, or a different variety of nut butter should work fine. Choose one with a creamy texture similar to regular peanut butter for the best results.

Whip the cream. Place the cream and vanilla in a separate bowl. Use an electric mixer with a whisk attachment to beat to stiff peaks. To minimize splatters, start on low speed and work up to medium-high speed over a minute or so.

Finish mixing. Transfer about a quarter of the whipped cream to the peanut butter mixture, and fold to combine. Then gently fold in the remaining whipped cream.

Chill. Divide the mousse among individual glasses or other serving dishes. Cover and refrigerate at least an hour, or up to overnight.

Tips for Success

Here are a few things to keep in mind when making this peanut butter mousse recipe.

Use room temperature cream cheese. Your mousse will mix more easily and have a smoother texture.
Don’t over-mix. Take care in the final step of mixing not to over-mix the mousse. Mix only as much as needed, otherwise you’ll deflate the whipped cream and lose the fluffy texture.
Want to make ahead? Prepare the mousse and refrigerate overnight. Add any toppings when you’re ready to serve.

How to Store

Keep this peanut butter mousse tightly covered in the refrigerator up to 4 days. While you can freeze the mousse, the texture is likely to be altered.
