The TASTIEST Chocolate Peanut Butter Ice Box Cake
If chocolate and peanut butter are your weakness, this dessert will be on heavy rotation. Layers of a silky peanut butter cream, crunchy chopped peanuts and thin chocolate wafer cookies are finished with a simple chocolate ganache for a luxurious final touch.
The recipe uses seven main ingredients for the cake and three ingredients for the ganache. It’s straightforward to assemble and requires mostly time in the freezer to set.
Chocolate Peanut Butter Ice Box Cake Ingredients
- Cream cheese (softened)
- Granulated sugar
- Creamy peanut butter
- Cold heavy cream
- Vanilla extract
- Peanuts (roughly chopped)
- Chocolate wafer cookies
Chocolate Ganache Ingredients
- Semisweet chocolate chips
- Unsalted butter
- Corn syrup
To prepare the filling, whisk the cream cheese and peanut butter together until smooth. Add the granulated sugar and vanilla, then slowly pour in the cold heavy cream while whisking. Increase the speed to medium-high and whip until the mixture holds stiff peaks. The result is a thick, mousse-like peanut butter cream that spreads beautifully between the cookie layers.
Line a 9×5-inch loaf pan with a double layer of plastic wrap, leaving plenty of overhang so the cake can be removed easily. Start by spreading a generous layer of the peanut butter cream in the bottom of the pan. Add a layer of chocolate wafer cookies (about a third of the package), then sprinkle on some chopped peanuts. Repeat the layers two more times and finish with a thin top layer of the peanut butter mixture. Smooth the surface with a spatula and cover with plastic wrap.
Freeze the loaf for at least 5–6 hours, or overnight. When ready to serve, transfer the cake to the refrigerator about an hour before serving so it softens slightly, making it easier to slice. Invert the loaf onto a serving plate, peel away the plastic wrap, and pour the cooled ganache over the top. Finish with extra chopped peanuts if desired, slice, and serve.
This ice box cake is perfect for warm-weather gatherings but enjoyable year-round. It’s easy to make ahead and travels well for potlucks or holiday tables. If you try it, let me know how it turns out — and feel free to ask any questions about the process.
A Few Cook’s Notes for Chocolate Peanut Butter Ice Box Cake
- Use any thin chocolate wafer cookie you prefer; Nabisco’s Famous Chocolate Wafers or similar thin wafers work well.
- Salted peanuts add a nice salty-sweet contrast, but unsalted peanuts are fine if you prefer less salt.
- Be generous with the plastic wrap overhang when lining the pan so you can lift the cake out easily.
- Freezing the cake makes it easier to slice cleanly. Remove it to the fridge about an hour before serving so it softens slightly.

Ingredients
Chocolate Peanut Butter Ice Box Cake
- 8 oz cream cheese, softened
- 1 cup creamy peanut butter
- 1 cup granulated sugar
- 1 tsp vanilla extract
- 2 cups cold heavy cream
- 3/4 cup salted or unsalted peanuts, roughly chopped (plus extra for topping)
- 36 chocolate wafer cookies

- 3/4 cup semisweet chocolate chips
- 3 Tbsp unsalted butter

Instructions
Chocolate Peanut Butter Ice Box Cake
- Line a 9×5-inch loaf pan with a double layer of plastic wrap, leaving plenty of overhang. Set aside.
- In the bowl of a stand mixer fitted with the whisk attachment, beat the cream cheese and peanut butter until smooth. Add the granulated sugar and vanilla and beat at medium speed until incorporated, about 2 minutes. Slowly add the cold heavy cream in a steady stream and increase the speed to medium-high. Whip until stiff peaks form.
- Spread a generous layer of the peanut butter cream in the bottom of the loaf pan. Add a layer of 12 chocolate wafer cookies and sprinkle with some chopped peanuts. Repeat the layers until the pan is full (about three layers total), finishing with a thin layer of the peanut butter cream. Smooth the top, cover with plastic wrap, and freeze 6 hours or overnight.
- Remove from the freezer about an hour before serving and place in the refrigerator to soften slightly. Uncover the loaf, place a serving platter on top, invert the cake, and peel away the plastic wrap. Pour the cooled chocolate ganache over the cake and top with extra chopped peanuts if desired. Slice and serve immediately.
Chocolate Ganache Topping
- Combine the chocolate chips and butter in a medium bowl. Microwave in 20-second intervals, stirring between each interval, until fully melted and smooth. Stir in the corn syrup until well combined. Allow to cool slightly before pouring over the cake.
Notes
You can use any thin chocolate wafer cookie—store-bought or homemade. Nabisco’s Famous Chocolate Wafers or similar work well.
Salted peanuts offer a nice contrast to the sweet filling, but unsalted peanuts are fine if you prefer less salt.
Make sure the plastic wrap has enough overhang so you can lift the cake from the pan easily.
Freeze the cake for easier slicing. Remove to the refrigerator about an hour before serving to soften slightly.
