What You’ll Need to Make Reese’s Peanut Butter Cup Roll Cake

Here’s what you’ll need to create this show-stopping dessert. Most of these ingredients are pretty common, but you might need to grab a few extra items for the peanut butter filling and ganache. Let’s get started!

For the cake:

3 large eggs
1 cup granulated sugar
1 teaspoon vanilla extract
1/3 cup unsweetened cocoa powder
1 teaspoon baking powder
1/4 teaspoon salt
1/4 cup water
Powdered sugar, for dusting

For the peanut butter filling:

1/2 cup creamy peanut butter (make sure it’s smooth)
1 cup powdered sugar
1/4 cup unsalted butter, softened
1 teaspoon vanilla extract
2 tablespoons heavy cream (or more for desired consistency)

For the chocolate ganache:

1/2 cup semi-sweet chocolate chips
1/4 cup heavy cream

For decoration (optional):

Mini Reese’s Peanut Butter Cups, chopped

How to Make Reese’s Peanut Butter Cup Roll Cake

Now, let’s dive into the steps to make this decadent dessert. It may seem like a lot, but I promise it’s totally doable. You can break it up into manageable steps and end up with a cake that looks (and tastes) like it came from a bakery.

Step 1: Make the Chocolate Cake Base

Preheat your oven to 350°F (175°C). Grease and line a 15×10-inch jelly roll pan with parchment paper, leaving a bit of an overhang on the sides to help with rolling later.
In a large bowl, beat the eggs and granulated sugar together until light and fluffy. This usually takes about 3 minutes with an electric mixer.
Add the vanilla extract, and mix again until well combined.
Sift the cocoa powder, baking powder, and salt into the egg mixture, and gently fold them in with a spatula until everything is incorporated.
Gradually add the water, mixing just until smooth. You’ll have a thin batter.
Pour the batter into your prepared pan and spread it out evenly with a spatula.
Bake for 10-12 minutes, or until a toothpick inserted into the center comes out clean. The cake should spring back when lightly touched.
Once the cake is done, remove it from the oven and immediately sprinkle a clean kitchen towel with powdered sugar.
Carefully flip the cake out of the pan onto the towel, peel off the parchment paper, and roll the cake up with the towel while it’s still warm. Let it cool completely while rolled up.

Step 2: Prepare the Peanut Butter Filling

While the cake is cooling, make the peanut butter filling. In a medium bowl, beat together the creamy peanut butter, powdered sugar, softened butter, and vanilla extract until smooth and fluffy.
Gradually add the heavy cream, a tablespoon at a time, until you get a spreadable consistency. You want it thick, but still easy to spread.
If the filling is too thick, add a little more cream until you’re happy with the texture.

Step 3: Unroll the Cake and Add the Peanut Butter Filling

Once the cake has cooled completely, gently unroll it from the towel. Don’t worry if it cracks a little—this is normal.
Spread the peanut butter filling evenly over the entire surface of the cake, leaving about a 1-inch border around the edges.
Carefully roll the cake back up, this time without the towel. You should have a nice, tight roll with the peanut butter filling inside.

Step 4: Make the Chocolate Ganache

In a small saucepan, heat the heavy cream over low heat until it just begins to simmer.
Remove from heat, and pour the hot cream over the semi-sweet chocolate chips in a bowl.
Stir until the chocolate is completely melted and smooth, forming a glossy ganache.

Step 5: Drizzle the Ganache and Decorate

Place the cake roll on a serving platter, and drizzle the chocolate ganache generously over the top of the cake.
If you’d like to add a little extra decoration, chop up some mini Reese’s Peanut Butter Cups and sprinkle them over the ganache. This adds a fun texture and extra burst of flavor!

Step 6: Let It Set and Serve

Allow the ganache to set for about 15-20 minutes, or until it firms up slightly.
Slice the cake into 1-inch thick slices and serve. You’ll be greeted with a beautiful swirl of cake, peanut butter filling, and chocolate ganache in every bite.

How I Like to Serve It

This Reese’s Peanut Butter Cup Roll Cake is perfect for any occasion, but here are a few of my favorite ways to enjoy it:

As a showstopper at a party: Everyone will be talking about how amazing this cake looks and tastes. Serve it at your next gathering or potluck, and you’ll be the star of the show.
With a scoop of vanilla ice cream: The creamy ice cream pairs perfectly with the rich, peanut butter-chocolate goodness of the cake. Plus, the cold ice cream helps balance out the sweetness of the cake.
As an after-dinner treat: After a meal, a small slice of this cake is the perfect way to end the night on a sweet note.

Tips for Perfect Reese’s Peanut Butter Cup Roll Cake

Let the cake cool completely: Rolling the cake while it’s warm helps prevent it from cracking, but it’s crucial that it cools before you add the filling to avoid melting.
Use smooth peanut butter: For the best texture in the filling, make sure you use creamy peanut butter, not chunky.
Don’t overfill the cake: While the peanut butter filling is delicious, you don’t want to add too much or it could overflow when you roll the cake.

Storing Leftovers

If you have any leftovers (which, let’s be honest, is unlikely), here’s how to store them:

In the fridge: Store any leftover slices of cake in an airtight container in the fridge for up to 3 days. The cake will stay moist and the peanut butter filling will stay creamy.
Freezing: You can freeze the cake for up to 2 months. Wrap individual slices in plastic wrap and place them in a freezer-safe bag or container. Thaw in the fridge overnight before serving.
