How to Make Peanut Butter Mousse?
Step 1: Mix the Peanut Butter Base 🥄
Start by combining smooth peanut butter, softened cream cheese, powdered sugar, and a splash of vanilla extract (if using) in a mixing bowl. Use an electric mixer to beat the mixture until it’s smooth and creamy.
Step 2: Whip the Cream 🌟
Take your heavy cream and beat it in a separate bowl until stiff peaks form. This step is crucial for getting that light, airy texture that makes the mousse so irresistible.
Step 3: Fold It All Together 🤲
Gently fold the whipped cream into the peanut butter mixture in batches. Start by mixing in one-quarter of the cream to lighten the base, then gradually fold in the remaining cream until everything is well-combined and fluffy.
Step 4: Pipe and Chill 🎉
Transfer the mousse into a piping bag for a fancy touch or simply spoon it into serving glasses. Serve immediately, or for a thicker, richer texture, refrigerate your mousse for about 30 minutes before serving.
Step 5: Garnish and Enjoy! 🍫
Top your mousse with crushed peanuts, chocolate shavings, or a drizzle of caramel for extra flair.

Tips for Making the Recipe
- Room Temperature Ingredients: Make sure the cream cheese is softened before mixing. This helps it blend smoothly with the peanut butter.
- Use Smooth Peanut Butter: Crunchy peanut butter won’t yield the same creamy texture, so stick with the smooth variety.
- Chill for Enhanced Flavor: While this mousse is delicious right away, a little chilling time allows the flavors to meld beautifully.
- Adjust the Sweetness: Taste the mixture after folding in the whipped cream. Add a pinch more powdered sugar if needed.
How to Serve Peanut Butter Mousse?
For a polished presentation, serve the mousse in small glass jars or elegant dessert cups. Add a final touch with toppings like cookie crumbs, mini chocolate chips, or a dollop of whipped cream. Pair it with fresh strawberries or banana slices for a complete dessert experience. With its beautiful layers and vibrant garnishes, it’s sure to wow your guests (or just yourself!).
Make Ahead and Storage
- Refrigerating: Cover the mousse and store it in the fridge for up to two weeks. The texture stays perfect, and the flavor may even improve as it sits.
- Freezing: For longer storage, freeze the mousse in an airtight container for up to six months. Remember to thaw it in the fridge overnight before serving.
- Pro Tip: If you’re making this for a party, prepare it the night before to save time and reduce stress on the day of!
There you have it! This peanut butter mousse is creamy, easy, and endlessly customizable. Whether you’re looking for a quick solo indulgence or an elegant dessert to share, this recipe delivers on all fronts. Try it once, and I guarantee it’ll become a regular in your dessert rotation.
