The first time I sunk a spoon into this peanut butter mousse pie, the kitchen smelled like nostalgia — warm Oreos and peanut butter, with a dark chocolate ribbon cutting through like late-evening jazz. It’s the kind of no-bake dessert that feels decadent and effortless at once, perfect for celebrations and quiet Sunday afternoons alike.
Why make this recipe

- It’s crowd-pleasing and flexible: dress it up with peanut butter cups or leave it elegantly simple.
How to make Peanut Butter Mousse Pie (No Bake)
Ingredients:
- 22 Oreos
- 5 tbsp melted butter
- 12 oz cream cheese, room temperature
- 1 1/2 cups smooth peanut butter
- 1 1/2 cups powdered sugar
- 1/2 tsp vanilla extract
- 1/4 tsp salt
- 1 1/2 cups heavy cream, cold
- 4 oz semisweet chocolate, chopped
- 1/2 cup heavy cream
- Peanut butter cups, for topping (optional)
Directions:
- To the mixing bowl of a food processor, add the chocolate sandwich cookies and the melted butter. Pulse repeatedly, until a fine crumb forms.
- Using your fingers first, and then the bottom of a measuring cup, smooth and compress the cookie and butter mixture into the bottom and up the sides of a pie tin. Move the prepared tin to the refrigerator while you make the mousse filling.
- To a large mixing bowl, add the cream cheese and beat on medium speed until fluffy, about 2 minutes. Add in the peanut butter, powdered sugar, vanilla and salt, and beat on medium speed for another minute.
- Add in the heavy cream and beat until the mixture is super light and fluffy, about 3 minutes.
- Pour the mousse mixture into the prepared pie tin and use an offset spatula or another long, flat tool to smooth it out. Move to the refrigerator and chill until the mousse firms up, about 2 to 3 hours.
- Heat the 1/2 cup of heavy cream until it’s steaming hot, but not boiling. To a small mixing bowl, add the chocolate. Pour the heated heavy cream over the chocolate, and let the mixture sit for 1-2 minutes, then whisk the mixture until the chocolate is fully melted and evenly incorporated into the heavy cream.
- Pour the ganache over the top of the pie and use an offset spatula or another long, flat tool to smooth out the ganache. Optionally, top with halved or quartered peanut butter cups along the edges of the pie.
- Move to the fridge and chill until set, about 30 to 60 minutes.
How to serve Peanut Butter Mousse Pie (No Bake)
- Serve chilled in clean slices to show the distinct layers. A dollop of whipped cream, a light sprinkle of flaky sea salt, or a few chopped peanuts adds contrast and shine.
- Pair with hot coffee or a glass of cold milk — the temperature contrast elevates the mousse’s silkiness.
How to store Peanut Butter Mousse Pie (No Bake)
- Refrigerate: Cover the pie loosely with plastic wrap or store in an airtight container for up to 4 days.
- Freeze: For longer storage, freeze individual slices wrapped tightly in plastic and foil for up to 1 month. Thaw in the refrigerator a few hours before serving.
Tips to make Peanut Butter Mousse Pie (No Bake)
- Bring cream cheese to room temperature for the smoothest mousse; cold cream cheese can make lumps.
- Use cold heavy cream and beat it into the mixture until light and airy — overbeating will turn it grainy.
- Press the crust firmly and evenly into the pan to avoid crumbling when slicing.
- Warm the chocolate ganache gently; do not overheat or you’ll risk a grainy finish.
- If your peanut butter is oily (natural style), stir it well before measuring so the texture is even.
Variations (if any)
- Salted Chocolate Swirl: Fold a light salted caramel ribbon into the mousse before chilling.
- Dark Chocolate Base: Use a darker ganache for a richer contrast.
- Nut Twist: Swap half the peanut butter for almond butter for a new flavor profile.
- Mini Pies: Make in a tart pan or individual ramekins for elegant single-serve presentations.
FAQs
Q: Can I use natural peanut butter?
A: Yes — but stir the jar well to reincorporate the oils. You may need to chill the mousse slightly longer to firm up due to a looser texture.
Q: Can I make this ahead of time?
A: Absolutely. The pie can be assembled a day ahead and refrigerated; it actually benefits from resting because the mousse firms and the flavors meld.
Q: What if my mousse is too soft?
A: Ensure the heavy cream was cold and whipped sufficiently. Chill the pie longer (up to 3 hours) and make sure your cream cheese was properly beaten before adding the cream.
Q: Is this safe to serve without baking anything?
A: Yes. All ingredients are pre-made or cooked (chocolate ganache is made with hot cream), so there’s no raw-egg risk and it’s safe when refrigerated.
Q: Can I make the crust using graham crackers instead of Oreos?
A: Yes — use crushed graham crackers and the same amount of butter for a lighter, less chocolate-forward base.
