Peanut Butter Mousse Recipe
Introduction
This peanut butter mousse is a silky, rich dessert that perfectly balances creamy peanut butter with light, airy whipped cream. It’s easy to make and ideal for a satisfying treat that feels indulgent without being too heavy.

Ingredients
- 1/4 tsp powdered gelatin
- 1/2 tbsp cold water
- 1 cup (280g) creamy peanut butter
- 3 tbsp (42g) packed light brown sugar
- 2 1/4 cups (540ml) heavy whipping cream, divided, cold
- 1/4 cup (29g) powdered sugar
- 1/2 tsp vanilla extract
- Chocolate chips or chocolate shavings, optional
Instructions
- Step 1: Add the cold water to a small bowl and sprinkle the gelatin evenly over it. Ensure all the gelatin is moistened. Let it sit for 5 minutes to bloom and firm up.
- Step 2: In a large bowl, combine 1 cup of heavy whipping cream and brown sugar with the peanut butter. Gently fold until well mixed. The peanut butter will thin and then thicken again.
- Step 3: Heat the gelatin for about 8-10 seconds until melted, then stir it into the peanut butter mixture until fully combined.
- Step 4: In a mixer bowl, whip the remaining 1 1/4 cups heavy cream with powdered sugar and vanilla extract until stiff peaks form. Fold one-third of this whipped cream into the peanut butter mixture, then fold in the rest until no streaks remain.
- Step 5: Spoon the mousse into 5-6 serving cups and refrigerate for 3-4 hours or overnight until set.
- Step 6: To prepare the whipped cream topping, whip 1/2 cup heavy cream with powdered sugar and vanilla extract until stiff peaks form.
- Step 7: Pipe or spoon the whipped cream over the chilled mousse. Garnish with chocolate chips or shavings if desired.
- Step 8: Keep the mousse refrigerated until serving. It’s best enjoyed within 3-4 days.
Tips & Variations
- For a crunchier texture, fold in chopped roasted peanuts before chilling the mousse.
- Use natural peanut butter for a more intense peanut flavor, but ensure it’s well stirred before measuring.
- If you don’t have gelatin, agar-agar can be a vegetarian alternative—follow package instructions for blooming and melting.
- Add a pinch of salt to balance the sweetness and enhance the peanut flavor.
Storage
Store the peanut butter mousse covered in the refrigerator for up to 3-4 days. Keep it chilled to maintain its texture. Rewhip the topping before serving if it loses volume.

Can I make this mousse ahead of time?
Yes, it’s perfect for making a day in advance, allowing the mousse to set overnight for best texture and flavor.
