Ingredients You’ll Need
This Peanut Butter Mousse Recipe calls for a handful of essential ingredients, each playing a crucial role in creating its luscious texture and unforgettable flavor. Every item on the list is easy to find yet invaluable, making the preparation straightforward without sacrificing taste.
- Peanut butter: Use creamy peanut butter for the smoothest consistency and richest flavor.
- Powdered sugar: This dissolves effortlessly, giving the mousse just the right amount of sweetness without grittiness.
- Heavy cream: Whipping this to soft peaks creates the light, airy texture that makes mousse so irresistible.
- Vanilla extract: Adds a warm, aromatic hint that perfectly complements the peanut butter.
- Pinch of salt: Enhances all the flavors, balancing the sweetness and deepening the peanut notes.
How to Make Peanut Butter Mousse Recipe
Step 1: Mix the base
Start by beating the peanut butter and powdered sugar together in a mixing bowl until you get a smooth, uniform mixture. This forms the sweet and nutty core of your mousse, so take your time to ensure there are no lumps and the texture is silky.
Step 2: Whip the cream
In a separate bowl, whip the heavy cream until soft peaks form—this means the cream should hold its shape gently without becoming stiff or grainy. Whipping the cream just right is key to getting that light, fluffy texture that makes this mousse so dreamy.
Step 3: Combine
Slowly fold the whipped cream into the peanut butter mixture. Be gentle here to preserve the airy texture from the cream while blending everything into a seamless, fluffy mousse. Folding rather than stirring lets the mousse keep its lightness.
Step 4: Add flavoring
Now stir in the vanilla extract and the pinch of salt. These add that little extra layer of flavor complexity that takes the mousse from good to unforgettable, highlighting the peanut butter’s natural richness.
Step 5: Chill
Cover the bowl and refrigerate the mousse for at least 2 hours. This chilling step lets the mousse set to the perfect creamy consistency, allowing all the flavors to meld beautifully.
Step 6: Serve and enjoy
When you’re ready to serve, spoon the mousse into dessert cups or bowls. It’s versatile enough to be a stand-alone dessert or a delicious topping for cakes and pies.
How to Serve Peanut Butter Mousse Recipe

Garnishes
Enhance the dessert experience by adding simple garnishes like chocolate shavings, crushed peanuts, or even a drizzle of melted chocolate. These touches add texture and visual appeal that make the mousse feel special and inviting.
Side Dishes
Peanut Butter Mousse pairs wonderfully with fresh fruit such as sliced bananas or strawberries, which bring a refreshing brightness to contrast the richness. For something more decadent, try serving it alongside a warm brownie or a crispy cookie for that delightful flavor and texture combination.
Creative Ways to Present
Try serving the mousse layered with crushed cookies or granola in a parfait glass for an impressive look and added crunch. Another idea is to pipe it into mini tart shells and chill until set for bite-sized treats that are perfect for parties or gatherings.
Make Ahead and Storage
Storing Leftovers
Store any leftover peanut butter mousse in an airtight container in the refrigerator. It will keep beautifully for up to 3 days, maintaining its creamy texture and flavor, ready for a quick indulgent snack or dessert whenever you want.
Freezing
While you can freeze Peanut Butter Mousse Recipe, it’s best to do so with caution, as freezing can affect the delicate texture. If you freeze it, place it in a sealed container for up to one month and thaw overnight in the refrigerator before serving. The texture might be slightly less airy but still delicious.
Reheating
This mousse is best enjoyed cold or at room temperature, so reheating is not recommended. Just let it sit out for 10 minutes if it feels a bit too chilled straight from the fridge, and you’ll experience its texture and flavor at their best.
FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! Crunchy peanut butter will add a bit of texture and extra peanut pieces, giving your mousse a delightful crunch. Just keep in mind the mousse won’t be as silky smooth but will be flavorful and exciting.
Is there a substitute for heavy cream?
Heavy cream is key for that fluffy texture, but you can try using full-fat coconut cream as a non-dairy alternative. It whips up nicely and adds a subtle coconut flavor that pairs surprisingly well with peanut butter.
How long does the mousse need to chill?
Chilling for at least 2 hours is necessary so the mousse can firm up to the perfect consistency. If you have time, letting it chill longer enhances the flavor meld and texture even more.
Can I make this Peanut Butter Mousse Recipe ahead of time for a party?
Yes! This mousse is excellent for make-ahead entertaining. Prepare it a day in advance and keep it refrigerated until serving. It saves you time and lets the flavors fully develop.
What can I add to customize the flavor?
Feel free to experiment by adding a pinch of cinnamon, a splash of bourbon, or even some espresso powder for a grown-up twist. Each addition can add a new depth to the peanut butter mousse, making it uniquely yours.
