Peanut Butter Mousse: The Ultimate Guide to a Delicious Dessert

June 23, 2025 by cookspotlight

Peanut butter mousse: just the name alone conjures up images of creamy, decadent, and utterly irresistible dessert perfection, doesn’t it? Forget complicated baking projects; this is your express ticket to a sophisticated treat that will have everyone begging for the recipe. Imagine a cloud of peanut butter-infused delight, melting in your mouth with each spoonful. It’s so good, you might just want to hide it from everyone else!

While not steeped in centuries of tradition like some classic desserts, peanut butter mousse has quickly become a modern favorite, and for good reason. Peanut butter itself has a fascinating history, evolving from a health food to a beloved staple. This mousse takes that familiar, comforting flavor and elevates it to something truly special.

What makes this dessert so universally appealing? It’s the perfect balance of sweet and salty, the incredibly smooth and airy texture, and the sheer convenience of it all. No baking required! It’s a fantastic make-ahead dessert for dinner parties, a delightful treat for a special occasion, or simply a way to indulge your peanut butter cravings any day of the week. Get ready to experience peanut butter in a whole new, luxurious way!

Peanut butter mousse this Recipe

Ingredients:

  • 1 cup (2 sticks) unsalted butter, softened
  • 1 cup creamy peanut butter (I prefer a no-stir variety for consistency)
  • 4 cups powdered sugar, sifted
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon salt
  • 1/4 cup heavy cream, plus more if needed
  • Optional: Chocolate shavings, chopped peanuts, or mini peanut butter cups for garnish

Preparing the Peanut Butter Base:

  1. First, make sure your butter is properly softened. It should be soft enough that you can easily press a finger into it, but not melted. If it’s too cold, it will be difficult to cream with the peanut butter and powdered sugar. If it’s too melted, the mousse won’t set up properly.
  2. In a large mixing bowl (or the bowl of your stand mixer), combine the softened butter and peanut butter. I like to use a stand mixer with the paddle attachment for this, but a hand mixer works just as well.
  3. Cream the butter and peanut butter together on medium speed until they are light and fluffy. This usually takes about 3-5 minutes. Don’t rush this step! The more air you incorporate, the lighter and smoother your mousse will be. Scrape down the sides of the bowl occasionally to ensure everything is evenly mixed. You should see a noticeable change in the texture and color as the mixture becomes lighter.
  4. Once the butter and peanut butter are well creamed, gradually add the sifted powdered sugar, one cup at a time. Sifting the powdered sugar is crucial to prevent lumps in your mousse. If you skip this step, you might end up with a grainy texture.
  5. After each addition of powdered sugar, mix on low speed until just combined. Be careful not to overmix, as this can develop the gluten in the powdered sugar and make the mousse tough. Scrape down the sides of the bowl after each addition to ensure all the powdered sugar is incorporated.
  6. Once all the powdered sugar has been added, increase the speed to medium and beat for another 2-3 minutes, or until the mixture is light and fluffy. Again, scrape down the sides of the bowl as needed.
  7. Add the vanilla extract and salt. Mix on low speed until just combined. The vanilla extract enhances the peanut butter flavor, and the salt balances the sweetness.

Achieving the Perfect Mousse Consistency:

  1. Now it’s time to add the heavy cream. Start with 1/4 cup and mix on low speed until just combined. The heavy cream will help to loosen the mixture and create a smooth, mousse-like texture.
  2. Check the consistency of the mousse. It should be light and airy, but still thick enough to hold its shape. If it’s too thick, add more heavy cream, one tablespoon at a time, until you reach the desired consistency. Be careful not to add too much cream, or the mousse will be too runny.
  3. If the mousse is too thin, you can add a tablespoon of powdered sugar at a time until it thickens up. However, try to avoid adding too much powdered sugar, as this can make the mousse overly sweet.
  4. Once you’re happy with the consistency, give the mousse one final mix on medium speed for about 30 seconds to ensure everything is well combined.

Chilling and Serving:

  1. Transfer the peanut butter mousse to a piping bag fitted with a decorative tip, or simply spoon it into individual serving dishes. I love using small glass bowls or ramekins for a pretty presentation.
  2. Cover the mousse with plastic wrap, pressing it directly onto the surface to prevent a skin from forming.
  3. Refrigerate the mousse for at least 2 hours, or preferably overnight. This will allow the mousse to set up properly and the flavors to meld together.
  4. Before serving, garnish with chocolate shavings, chopped peanuts, or mini peanut butter cups, if desired. These add a nice visual appeal and enhance the peanut butter flavor.
  5. Serve chilled and enjoy! This peanut butter mousse is delicious on its own, but it’s also great served with fresh berries, graham crackers, or chocolate cookies.

Tips and Variations:

  • For a richer flavor: Use dark chocolate shavings or chopped dark chocolate instead of milk chocolate.
  • For a salty-sweet twist: Sprinkle a pinch of sea salt on top of each serving.
  • For a vegan version: Use vegan butter and peanut butter, and substitute the heavy cream with coconut cream. Make sure to refrigerate the coconut cream overnight and only use the thick part from the top of the can.
  • For a chocolate peanut butter mousse: Add 1/4 cup of unsweetened cocoa powder to the peanut butter base along with the powdered sugar.
  • To make parfaits: Layer the peanut butter mousse with crushed graham crackers and whipped cream in a tall glass.
  • Storage: The peanut butter mousse can be stored in the refrigerator for up to 3 days.
  • Freezing: While you can freeze this mousse, the texture may change slightly upon thawing. If you do freeze it, wrap it tightly in plastic wrap and then in aluminum foil. Thaw in the refrigerator overnight.
  • Troubleshooting: If your mousse is too grainy, it could be due to not sifting the powdered sugar or not creaming the butter and peanut butter properly. If your mousse is too runny, you may have added too much heavy cream. If your mousse is too thick, add a tablespoon of heavy cream at a time until you reach the desired consistency.

Detailed Notes on Ingredients:

  • Butter: Using high-quality unsalted butter is key to achieving the best flavor and texture. Make sure the butter is softened to room temperature before you start.
  • Peanut Butter: I recommend using a creamy, no-stir peanut butter for this recipe. Natural peanut butter can sometimes be too oily and separate, which can affect the consistency of the mousse.
  • Powdered Sugar: Sifting the powdered sugar is essential to prevent lumps in the mousse. If you don’t have a sifter, you can use a fine-mesh sieve.
  • Vanilla Extract: Use pure vanilla extract for the best flavor. Imitation vanilla extract can have a slightly artificial taste.
  • Heavy Cream: The heavy cream adds richness and helps to create a smooth, mousse-like texture. You can substitute it with whipping cream, but the mousse will be slightly less rich.
  • Salt: A pinch of salt balances the sweetness of the peanut butter and powdered sugar and enhances the overall flavor.

Serving Suggestions:

  • Serve the peanut butter mousse in individual serving dishes, such as small glass bowls or ramekins.
  • Garnish with chocolate shavings, chopped peanuts, or mini peanut butter cups.
  • Serve with fresh berries, such as strawberries, raspberries, or blueberries.
  • Serve with graham crackers or chocolate cookies for dipping.
  • Use the peanut butter mousse as a filling for cakes or cupcakes.
  • Layer the peanut butter mousse with crushed graham crackers and whipped cream in a tall glass to make parfaits.

Why This Recipe Works:

This peanut butter mousse recipe is a guaranteed crowd-pleaser because it strikes the perfect balance between rich, creamy, and intensely peanut buttery. The key to its success lies in a few simple techniques:

  • Properly Creaming the Butter and Peanut Butter: This step is crucial for incorporating air into the mixture, which results in a light and fluffy mousse.
  • Sifting the Powdered Sugar: This prevents lumps and ensures a smooth texture.
  • Adding Heavy Cream Gradually: This allows you to control the consistency of the mousse and prevent it from becoming too runny.
  • Chilling the Mousse: This allows the flavors to meld together and the mousse to set up properly.

By following these tips and techniques, you’ll be able to create a peanut butter mousse that is sure to impress your friends and family. Enjoy!
