Ingredients You’ll Need
These Peanut Butter Mousse Cups rely on a handful of straightforward yet key ingredients that work harmoniously to achieve a lush, balanced dessert. Each one adds an important element, from the silky ganache to the fluffy mousse and the creamy topping.
- Semi-sweet chocolate: The base for the ganache, bringing a rich and slightly bitter tone to contrast the sweetness.
- Peanut butter: Provides that unmistakable creamy, nutty flavor at the heart of the mousse.
- Cream cheese: Adds tanginess and a velvety texture to the mousse, enhancing its depth.
- Heavy cream: Whipped to give the mousse its signature lightness and used again for the whipped cream topping.
- Powdered sugar: Sweetens gently without affecting texture, keeping the mousse smooth and luscious.
- Reese’s peanut butter cups (or favorite candy): For a crunchy, nutty garnish that adds a playful finish.
How to Make Peanut Butter Mousse Cups
Step 1: Prepare the Chocolate Ganache
Start by heating heavy cream until it’s just about to simmer, then pour it over the chopped semi-sweet chocolate. Let it sit for a moment to soften before stirring gently until silky smooth. This glossy ganache forms the first, indulgent layer of your mousse cups, creating a sumptuous chocolate foundation that pairs perfectly with peanut butter.
Step 2: Make the Peanut Butter Mousse
In a mixing bowl, beat the cream cheese until smooth, then add the peanut butter and powdered sugar, blending until creamy and well combined. In a separate bowl, whip the heavy cream to soft peaks and gently fold it into the peanut butter mixture. This step preserves the airy texture while combining all the luscious flavors that define this mousse.
Step 3: Assemble the Cups
Layer the ganache into your serving cups first, then spoon or pipe the peanut butter mousse over it carefully. The contrast in layers should be distinct and visually appealing, making it as much a feast for the eyes as for the palate.
Step 4: Finish with Whipped Cream and Toppings
Whip the remaining heavy cream with a bit of powdered sugar until fluffy and airy, then dollop or pipe it over the mousse layer. Sprinkle crushed Reese’s peanut butter cups or your favorite candy on top for that perfect final touch of chocolatey crunch and peanut butter delight.
How to Serve Peanut Butter Mousse Cups

Garnishes
Adding crushed peanut butter cups is the classic way to finish these mousse cups, offering extra texture and flavor. You can also toss in chocolate shavings, a sprinkle of sea salt, or even a drizzle of caramel sauce to elevate the taste and presentation.
Side Dishes
This dessert shines on its own but can also be paired with fresh berries to cut through the richness or a warm cup of coffee or tea to complement the nutty and chocolate notes perfectly. It’s a flexible treat that can adapt to your mood and company.
Creative Ways to Present
Try serving these Peanut Butter Mousse Cups in small glass jars, elegant stemmed glasses, or even mini mason jars for a rustic yet stylish touch. Layering with a bit of crushed cookies or adding a decorative swirl to the whipped cream brings added charm for special occasions.
Make Ahead and Storage
Storing Leftovers
These mousse cups keep wonderfully in the refrigerator, covered, for up to three days. Keeping them chilled ensures the mousse maintains its fluffy texture and the ganache stays firm but soft to the bite.
Freezing
You can freeze Peanut Butter Mousse Cups if needed, but be sure to wrap them well and leave enough headspace in the container. Thaw in the refrigerator a few hours before serving to avoid any texture changes in the mousse and whipped cream layers.
Reheating
This dessert is best enjoyed cold, so reheating is not recommended. Instead, allow frozen cups to thaw gently in the fridge. If you want a slightly softer texture, let them sit at room temperature for 15 to 20 minutes before serving.
FAQs
Can I use crunchy peanut butter for the mousse?
Absolutely! Using crunchy peanut butter will introduce lovely bits of texture to the mousse, making it a fun twist on the classic smooth version.
Is it necessary to use cream cheese in the mousse?
Cream cheese adds a slight tang and stabilizes the mousse, but you could experiment with mascarpone or even Greek yogurt for different flavor profiles and textures.
How long does it take to make these Peanut Butter Mousse Cups?
From start to finish, expect about 30 to 40 minutes for preparation, plus at least an hour of chilling to let the layers set properly before serving.
Can I make these dessert cups vegan?
To make a vegan version, substitute dairy cream with coconut cream, use dairy-free chocolate, and find a vegan cream cheese alternative. The texture and flavor will be slightly different but still delicious!
What other toppings work well with Peanut Butter Mousse Cups?
Besides crushed peanut butter cups, consider chopped nuts, a sprinkle of sea salt, cocoa nibs, or even a drizzle of honey or maple syrup for natural sweetness layers.
