There’s something undeniably nostalgic about the combination of chocolate and peanut butter. It’s rich, comforting, and just a little bit indulgent—in the best way possible. Now imagine that classic flavor duo wrapped into a soft, fluffy chocolate sponge cake, rolled up with a creamy peanut butter filling, and finished with silky chocolate ganache. That’s exactly what you get with this Peanut Butter Cup Chocolate Roll.
Why You’ll Love This Recipe
First of all, the flavor combination is unbeatable. Chocolate and peanut butter are a match made in dessert heaven. The deep cocoa flavor of the sponge cake pairs perfectly with the creamy, slightly salty peanut butter filling. Add chopped peanut butter cups, and you get layers of texture that make every bite exciting.
You’ll also love how impressive it looks. A cake roll always feels a little fancy. The spiral of chocolate cake and peanut butter filling creates a beautiful swirl when sliced. Top it with glossy ganache, and suddenly it looks bakery-worthy.
Another reason? It’s make-ahead friendly. You can prepare it a day in advance and store it in the refrigerator until you’re ready to serve. In fact, chilling it helps the flavors meld together and makes slicing even easier.
Ingredients You’ll Need
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
Chocolate Sponge Cake
- ¾ cup all-purpose flour
- ¼ cup unsweetened cocoa powder
- 1 teaspoon baking powder
- ¼ teaspoon salt
- 4 large eggs, at room temperature
- ¾ cup granulated sugar
- 2 tablespoons vegetable oil
- 1 teaspoon vanilla extract
- ¼ cup milk
Peanut Butter Filling
- ¾ cup creamy peanut butter
- ½ cup powdered sugar
- ½ cup heavy cream
- 1 teaspoon vanilla extract
- 1 cup chopped peanut butter cups
Optional Ganache Topping
- ½ cup heavy cream
- ¾ cup semi-sweet chocolate chips
Each ingredient plays an important role. The eggs are essential for structure and lift in the sponge cake. Beating them properly creates that light, flexible texture needed for rolling. Cocoa powder brings rich chocolate flavor without making the cake too heavy.
The peanut butter filling balances sweetness with creaminess. Heavy cream helps whip the filling into a smooth, spreadable texture, while powdered sugar adds just the right amount of sweetness. The chopped peanut butter cups? They’re the surprise factor—little nuggets of chocolate-peanut goodness throughout.
Let’s Get Started
– Preheat your oven to 350°F (175°C). Line a 10×15-inch jelly roll pan with parchment paper and lightly grease it to prevent sticking.
– In a medium bowl, sift together flour, cocoa powder, baking powder, and salt. Set aside. In a large mixing bowl, beat the eggs and granulated sugar together for about 3–5 minutes, until pale, thick, and slightly fluffy. This step is crucial—it creates volume for the sponge.
– Add vegetable oil, vanilla extract, and milk. Mix until combined. Gently fold the dry ingredients into the egg mixture, being careful not to deflate the batter. Pour the batter evenly into the prepared pan and smooth the top.
– Bake for 10–12 minutes, or until the cake springs back lightly when touched.
– While the cake is still warm, carefully invert it onto a clean kitchen towel dusted lightly with powdered sugar. Peel off the parchment paper. Starting from the short end, roll the cake up gently with the towel inside. Let it cool completely in this rolled shape. This prevents cracking later.
– For the filling, beat the peanut butter and powdered sugar until smooth. In a separate bowl, whip the heavy cream until soft peaks form, then fold it into the peanut butter mixture along with vanilla extract. Stir in chopped peanut butter cups.
– Once the cake has cooled, carefully unroll it. Spread the peanut butter filling evenly over the surface, leaving a small border around the edges. Roll it back up tightly without the towel.
– For the ganache, heat the heavy cream until just simmering, then pour over chocolate chips. Let sit for a minute, then stir until smooth. Pour over the cake roll and let set before slicing.
Servings and Pairing
This Peanut Butter Cup Chocolate Roll serves about 8–10 slices, depending on how thick you cut each piece. It’s rich enough that a small slice goes a long way.
Pair it with a hot cup of coffee or espresso to balance the sweetness. A glass of cold milk works beautifully, especially if serving to kids. For a dinner party, consider pairing it with a scoop of vanilla ice cream or a dollop of lightly sweetened whipped cream.
If you want to elevate the presentation, sprinkle extra chopped peanut butter cups or a dusting of cocoa powder on top before serving.
Variations
There are plenty of ways to customize this cake roll.
Swap creamy peanut butter for crunchy for added texture.
Add a layer of chocolate ganache inside before spreading the filling for extra richness.
Mix mini chocolate chips into the filling.
Drizzle caramel sauce over the top for a sweet-salty twist.
Use dark chocolate chips for a deeper, less sweet flavor.
You can even make it festive by decorating with seasonal sprinkles or holiday-themed candies.
Storage Tips
Store the cake roll in an airtight container in the refrigerator for up to 4 days. Because of the whipped cream in the filling, it should remain chilled.
For best texture, let it sit at room temperature for about 15–20 minutes before serving. This softens the filling slightly and enhances the flavors.
You can also freeze the roll (without ganache) wrapped tightly in plastic wrap for up to 2 months. Thaw overnight in the refrigerator before adding ganache and serving.
FAQs
Why did my cake crack when rolling?
Cracking usually happens if the cake cools completely before being rolled the first time. Always roll it while warm to maintain flexibility.
Can I make this ahead of time?
Yes. It’s actually better when chilled for several hours or overnight.
Can I use natural peanut butter?
It’s not recommended, as natural peanut butter can be too oily and affect the texture of the filling.
Do I have to add ganache?
No. The cake is delicious on its own, but ganache adds extra richness and a polished finish.
Can I make it gluten-free?
Yes, substitute the all-purpose flour with a 1:1 gluten-free baking blend.
Final Thoughts
Peanut Butter Cup Chocolate Roll is the perfect blend of elegance and comfort. It combines a light chocolate sponge, creamy peanut butter filling, and optional silky ganache into one irresistible dessert.
