Chocolate Peanut Butter Caramel Mousse Pie
Ingredients
For the Crust
- 2 cups chocolate cookie crumbs about 24 chocolate sandwich cookies, filling removed
- 6 tablespoons unsalted butter melted
- 2 tablespoons granulated sugar
For the Caramel Layer
- 1 cup granulated sugar
- ¼ cup water
- ¾ cup heavy cream room temperature
- 4 tablespoons unsalted butter room temperature
- ½ teaspoon sea salt optional, for salted caramel flavor
For the Peanut Butter Layer
- 1 cup creamy peanut butter not natural style
- 8 oz cream cheese softened
- ½ cup powdered sugar
- 1 teaspoon vanilla extract
- 1 cup heavy cream whipped to stiff peaks
For the Chocolate Mousse Layer
- 8 oz semi-sweet chocolate chopped
- 2 tablespoons unsalted butter
- 3 large eggs separated (room temperature)
- ¼ cup granulated sugar
- 1 cup heavy cream whipped to soft peaks
- 1 teaspoon vanilla extract
For Garnish
- ½ cup chopped peanuts
- ¼ cup chocolate shavings
- Extra caramel sauce for drizzling
Instructions
- Prepare the crust by combining chocolate cookie crumbs, melted butter, and sugar in a bowl until evenly moistened. Press firmly into the bottom and slightly up the sides of a 9-inch springform pan. Refrigerate for at least 30 minutes to set.
- Make the caramel sauce by combining sugar and water in a medium saucepan over medium heat. Do not stir after this point! Swirl the pan occasionally until the mixture turns a deep amber color (about 8-10 minutes). Carefully add the heavy cream (it will bubble vigorously), then whisk in butter and salt until smooth. Set aside 2 tablespoons for garnish and allow the rest to cool completely.
- Create the peanut butter layer by beating cream cheese and peanut butter with an electric mixer until smooth. Add powdered sugar and vanilla, mixing until fully incorporated. Gently fold in the whipped cream until no streaks remain, being careful not to deflate the mixture.
- Pour cooled caramel sauce over the chilled crust, creating an even layer. Refrigerate for 15 minutes to set slightly before proceeding to the next step.
- Spread the peanut butter layer carefully over the caramel layer, smoothing the top with a spatula. Return to the refrigerator while preparing the chocolate mousse.
- Prepare the chocolate mousse by melting chocolate and butter together in a heatproof bowl set over simmering water (or microwave in 30-second intervals, stirring between each). Allow to cool slightly but remain fluid.
- Beat egg yolks and sugar in a separate bowl until pale and thick (about 3 minutes). Gradually whisk in the melted chocolate mixture until fully incorporated.
- Whip egg whites in a clean bowl until stiff peaks form. In another bowl, whip the heavy cream with vanilla until soft peaks form.
- Fold whipped egg whites into the chocolate mixture first, then gently fold in the whipped cream until just combined, maintaining as much air as possible in the mixture.
- Carefully spread the chocolate mousse over the peanut butter layer, creating a smooth, even top. Refrigerate the entire pie for at least 4 hours or preferably overnight.
- Before serving, garnish the pie with chopped peanuts, chocolate shavings, and a drizzle of the reserved caramel sauce. Carefully remove the springform ring before slicing.
Notes
- The key to perfect layers is patience – allow each layer to set before adding the next.
- For best results, ensure all refrigerated ingredients (cream cheese, eggs, cream) come to room temperature before using.
- This pie can be made up to 2 days in advance and kept refrigerated.
- For cleaner slices, dip your knife in hot water and wipe dry between cuts.
- If you’re concerned about raw eggs, use pasteurized eggs for the mousse, or substitute with a package of instant chocolate pudding mixed with 1½ cups cold milk.

Common Mistakes to Avoid
- Overheating the caramel – Watch it closely as it can go from perfect to burnt in seconds. Look for a deep amber color, not dark brown.
- Using natural peanut butter – The oils separate and can make your filling too loose. Stick with conventional creamy peanut butter for consistent results.
- Rushing the chilling process – Each layer needs time to set properly, or they’ll blend together and lose definition.
- Overwhipping the cream – If it turns grainy, you’ve gone too far. Stop at soft peaks for the mousse and stiff peaks for the peanut butter layer.
- Getting water in your chocolate – Even a drop will cause it to seize. Keep all utensils and bowls completely dry when melting chocolate.
Alternatives & Substitutions
- Dietary needs: For gluten-free, use gluten-free chocolate cookies for the crust.
- No peanut butter: Substitute almond butter or cookie butter for a different but equally delicious flavor profile.
- Lighter version: Use Neufchâtel cheese instead of regular cream cheese and light whipping cream (though the texture will be slightly different).
- Shortcut options: Use store-bought caramel sauce (about 3/4 cup) if you’re short on time.
- Flavor variations: Add 1/2 teaspoon espresso powder to the chocolate mousse for a mocha twist, or include 1/4 teaspoon cinnamon in the peanut butter layer for subtle warmth.
FAQs
Can I make this pie ahead of time?
Absolutely! This pie actually benefits from being made a day ahead, allowing all the flavors to meld together and the layers to set perfectly. It will keep well in the refrigerator for up to 3 days.
How do I know when my caramel is the right color?
Look for a deep amber color, similar to honey. If it’s too light, it will be overly sweet without complexity; too dark, and it will taste burnt. When in doubt, err on the lighter side.
Can I freeze this pie?
Yes, but with some caveats. Freeze it without the garnishes, tightly wrapped, for up to 1 month. Thaw overnight in the refrigerator, then add fresh garnishes before serving. The texture may change slightly but will still be delicious.
My chocolate seized when I was melting it. Can I save it?
If your chocolate becomes grainy or seizes, try adding 1-2 teaspoons of vegetable oil and stirring gently over low heat. For severely seized chocolate, it’s best to start over to ensure a smooth mousse.
Is there a way to make this without raw eggs?
Yes! You can either use pasteurized eggs, which are safe to eat raw, or substitute the mousse with a package of instant chocolate pudding mixed with 1½ cups cold milk, folded with 1 cup of whipped cream.
