Why You’ll Love This Peanut Butter Cup Chocolate Roll Cake

You’ll love this dessert because it strikes the perfect balance between elegance and fun. It has all the charm of a Swiss roll but with a flavor combo that everyone loves. The light sponge contrasts perfectly with the creamy filling, and the ganache topping brings it all together.

Plus, this recipe doesn’t require any fancy tools, just a simple jelly roll pan and a few mixing bowls. It’s also make-ahead friendly, so you can prep it in advance and serve when you’re ready to impress.

Can I Use a Boxed Cake Mix for the Roll?

You can use a boxed cake mix in a pinch, but for the best texture and flavor, I highly recommend making the sponge cake from scratch. Boxed mixes tend to be too moist and may crack when rolled. The homemade version is light, flexible, and made specifically to hold up to rolling without falling apart.

Ingredients for the Peanut Butter Cup Chocolate Roll Cake

This cake combines simple ingredients you likely already have in your pantry. Each plays a role in creating the perfect texture and taste, from the airy sponge to the rich filling.

Eggs: These give the sponge cake its structure and airy texture. You’ll need to separate them and beat the whites to help the cake rise.

Granulated Sugar: Sweetens the cake and helps create a tender crumb.

Vanilla Extract: A subtle depth of flavor that enhances both the cake and the filling.

All-Purpose Flour: Provides structure to the cake without making it heavy.

Cocoa Powder: Use unsweetened cocoa powder for a rich chocolate flavor that balances the sweet filling.

Baking Powder: Gives the sponge cake its rise.

Salt: Just a pinch to enhance the chocolate and peanut butter flavors.

Heavy Cream: Used in both the peanut butter filling and chocolate ganache, it makes both luxuriously smooth.

Creamy Peanut Butter: This is the heart of the filling. Choose a shelf-stable, no-stir peanut butter for best results.

Powdered Sugar: Sweetens and thickens the peanut butter filling.

Semi-Sweet Chocolate Chips: For the ganache topping that finishes the cake with a glossy, rich coat.

How To Make the Peanut Butter Cup Chocolate Roll Cake

Step 1: Prepare the Sponge Cake

Preheat your oven to 350°F. Line a jelly roll pan (10×15-inch) with parchment paper and spray lightly with non-stick spray. In a large bowl, beat the egg yolks with sugar and vanilla until thick and pale. In a separate bowl, beat the egg whites to stiff peaks. Sift together flour, cocoa powder, baking powder, and salt. Gently fold the dry ingredients into the egg yolk mixture, then fold in the egg whites. Spread the batter evenly in the pan and bake for 10-12 minutes.

Step 2: Roll While Warm

Immediately after removing the cake from the oven, turn it out onto a clean kitchen towel dusted with powdered sugar. Peel off the parchment and gently roll the cake with the towel from short end to short end. Let it cool completely in this rolled shape.

Step 3: Make the Peanut Butter Filling

Beat the creamy peanut butter with powdered sugar, vanilla, and a bit of heavy cream until smooth and fluffy. Unroll the cooled cake, spread the filling evenly across the surface, then gently roll it back up (without the towel this time).

Step 4: Make the Ganache

Heat heavy cream until hot but not boiling, then pour over the chocolate chips in a bowl. Let sit for a minute, then stir until smooth. Pour the ganache over the top of the rolled cake and let it set slightly before serving.

Step 5: Chill and Slice

Refrigerate the cake for at least 1 hour to firm up before slicing. Serve chilled or at room temperature for the best texture.

Serving and Storing the Peanut Butter Cup Chocolate Roll Cake
