How to Make Peanut Butter Mousse with Chocolate Ganache Recipe
Step 1: Whip the Heavy Cream
Start by pouring 1 1/2 cups of heavy cream into a large mixing bowl. Use an electric mixer on medium-high speed to whip the cream until stiff peaks form. This fluffy whipped cream is what will give your peanut butter mousse its signature light and airy texture.
Step 2: Chill the Whipped Cream
Pop the bowl of whipped cream into the fridge as you move forward. Keeping it cool will help maintain its volume and integrate perfectly with the peanut butter mixture later.
Step 3: Beat the Cream Cheese
In a separate bowl, beat 8 ounces of cream cheese until it becomes smooth and creamy. This step ensures your mousse has a silky, melt-in-the-mouth feel that pairs perfectly with peanut butter’s richness.
Step 4: Add Peanut Butter
Stir in 1 cup of peanut butter to the cream cheese, beating until fully combined. The peanut butter is the star here, infusing the mixture with its nutty goodness and thick, satisfying flavor.
Step 5: Sweeten the Mousse
Add 1/4 cup powdered sugar and 1 teaspoon vanilla extract. Beat everything together until smooth, blending the sweetness and aromatic vanilla evenly through the peanut butter cream.
Step 6: Fold in Whipped Cream
Now, gently fold the chilled whipped cream into your peanut butter mixture in three parts. This step requires a light hand—fold carefully to keep as much air as possible for light, fluffy mousse.
Step 7: Chill the Mousse
Transfer your mousse mixture into your serving dish or individual cups. Place them in the fridge and let them chill for at least 2 hours, or until the mousse is beautifully set.
Step 8: Prepare the Chocolate Ganache
While the mousse is chilling, make your ganache by heating 1/4 cup of heavy cream in a small saucepan until it just begins to simmer. Remove from heat and quickly add 1/2 cup milk chocolate chips along with 1 tablespoon unsalted butter.
Step 9: Create a Glossy Ganache
Stir the mixture gently until the chocolate fully melts and smooths out into a shiny, luscious ganache. Let it cool a bit, but be careful to pour it before it hardens.
Step 10: Add Ganache Topping
Once the mousse has set, pour the cooled ganache evenly over the top. Use a spatula to spread it gently and cover the mousse completely.
Step 11: Final Chill
Pop the dessert back into the fridge for about 30 minutes to let the ganache set firm but still silky. Then it’s ready to serve!
How to Serve Peanut Butter Mousse with Chocolate Ganache Recipe

Garnishes
To elevate the presentation and texture, sprinkle some chopped roasted peanuts or a few chocolate shavings on top. A tiny pinch of flaky sea salt can also be a game-changer, balancing the sweetness and enhancing the chocolate and peanut flavors.
Side Dishes
This mousse pairs beautifully with fresh berries like raspberries or strawberries, which add a refreshing tangy contrast. Serve alongside espresso or a rich coffee to round out the dessert experience perfectly.
Creative Ways to Present
Try layering the mousse and ganache in clear glasses for an elegant parfait look. Alternatively, pipe the mousse into pretty swirls and then drizzle the ganache artistically on top for an Instagram-worthy treat that tastes as amazing as it looks.
Make Ahead and Storage
Storing Leftovers
Your Peanut Butter Mousse with Chocolate Ganache Recipe keeps well covered in the fridge for up to 3 days. Make sure to seal it tightly with plastic wrap or an airtight lid to preserve the mousse’s delicate texture and prevent it from absorbing any odors.
Freezing
You can freeze the mousse, but the texture might change upon thawing. If you do freeze it, place it in a freezer-safe container and consume within one month. Thaw overnight in the fridge for best results before serving.
Reheating
This dessert is best enjoyed cold, so reheating is not recommended. Instead, simply allow it to sit at room temperature for about 10 minutes before serving if it feels too firm straight from the fridge.
FAQs
Can I substitute peanut butter with another nut butter?
Absolutely! Almond or cashew butter can work as delicious alternatives, but keep in mind they will change the flavor profile slightly. Make sure to use smooth nut butters to maintain the mousse’s silky texture.
Is it necessary to use cream cheese in this recipe?
Cream cheese adds a slight tanginess and nice firmness to the mousse. If you want a dairy-free option, you can experiment with vegan cream cheese, but the texture might differ a bit.
Can I use dark chocolate instead of milk chocolate for the ganache?
Yes! Dark chocolate pairs wonderfully with the peanut butter mousse and will create a richer, less sweet ganache. Adjust the sweetness accordingly if you prefer a darker, more intense chocolate flavor.
How long does it take to make this dessert?
The active preparation takes about 20 minutes, and you need to allow at least 2 hours for chilling the mousse plus 30 minutes for the ganache to set. It’s a great make-ahead treat for your gatherings.
Can I prepare this dessert in individual servings ahead of time?
Definitely! Preparing it in individual cups is perfect for parties or dinners. Just remember to keep them refrigerated until serving to preserve the mousse’s texture and the ganache’s glossy finish.
