Ingredients & Substitutions
Every ingredient in this recipe serves a distinct scientific purpose. Proper temperature and measurement are the keys to a flawless Peanut Butter Cup Chocolate Roll.
The Dark Chocolate Sponge
Cake Flour: You need 1/2 cup (60g) of sifted cake flour. Its low protein content prevents gluten development, ensuring the sponge remains incredibly soft and flexible for rolling.
Dutch-Processed Cocoa Powder: Use 1/3 cup (40g) of Dutch-processed cocoa. This neutralizes acidity and provides the deep, dramatic dark color required for a striking visual contrast.
Large Eggs (Separated): You will need 4 large eggs (200g total), separated into yolks and whites. Whipping the whites provides the necessary aeration, while the yolks add richness and fat.
Granulated Sugar: Measure out 1/2 cup (100g) of granulated sugar. This sweetens the cake and helps stabilize the whipped egg whites into a glossy meringue.
Vegetable Oil & Buttermilk: Use 2 tbsp (30ml) of neutral oil and 2 tbsp (30ml) of buttermilk. The oil ensures a moist crumb that bends without breaking, while buttermilk tenderizes the batter.
Vanilla, Baking Powder & Salt: You need 1 tsp (5ml) pure vanilla extract, 1 tsp (5g) baking powder, and 1/4 tsp (1g) salt. These foundational ingredients provide lift and enhance the chocolate’s natural flavor.
The Peanut Butter & Vanilla Cream Filling
Cream Cheese: Soften 8 oz (225g) of full-fat cream cheese. This provides the structural integrity required to keep the filling thick and stable when sliced.
Creamy Peanut Butter: Use 3/4 cup (190g) of standard creamy peanut butter (avoid natural varieties). It delivers a smooth, cohesive texture and intense nutty flavor.
Heavy Whipping Cream: Pour 1 cup (240ml) of cold heavy cream. Whipping this into the base creates a light, creamy volume that prevents the filling from becoming too dense.
Powdered Sugar & Vanilla: Sift 1 cup (120g) of powdered sugar and add 1 tsp (5ml) of vanilla extract. This sweetens the cream while allowing the vanilla notes to shine through the peanut butter.
The Ganache & Garnish
Dark Chocolate Chips & Heavy Cream: Combine 1/2 cup (85g) of dark chocolate chips with 1/3 cup (80ml) of heavy cream. Melting these together creates the glossy, fluid ganache for the topping.
Peanut Butter Cups & Crushed Peanuts: Chop 1/2 cup (75g) of peanut butter cups and 1/4 cup (35g) of roasted peanuts. These add crucial crunch and visual appeal.
Powdered Sugar: Reserve 1 tbsp (8g) of powdered sugar. A final dusting mimics a professional bakery finish.
Equipment Needed
- 10×15-inch Jelly Roll Pan: The exact dimensions ensure the sponge is the correct thickness for rolling.
- Parchment Paper: Crucial for preventing the delicate cake from sticking to the pan.
- Clean Kitchen Towel: Used to roll the hot cake, helping it memorize its spiral shape.
- Electric Stand Mixer or Hand Mixer: Necessary for whipping the egg whites to stiff peaks and volumizing the filling.
Step-by-Step Instructions
Follow these instructions closely. The culinary techniques here ensure structural integrity and the ultimate dramatic presentation.
1. Prepare the Baking Equipment
Preheat your oven to 350°F (175°C). Lightly grease a 10×15-inch jelly roll pan, line it with parchment paper, and lightly grease the parchment.
Dust a clean, lint-free kitchen towel generously with cocoa powder. This acts as a non-stick surface for the hot cake.
2. Create the Dark Chocolate Sponge Batter
In a large bowl, whisk the 4 egg yolks, 1/4 cup (50g) of the granulated sugar, vegetable oil, buttermilk, and vanilla until pale and frothy. Sift the cake flour, Dutch-processed cocoa powder, baking powder, and salt directly into the yolk mixture.
Fold gently until just combined. The batter will look thick and deeply dark.
3. Whip the Meringue and Fold
In a separate clean bowl, whip the 4 egg whites until soft peaks form. Gradually pour in the remaining 1/4 cup (50g) of granulated sugar while mixing on high speed.
Whip until stiff, glossy peaks form. Gently fold the meringue into the chocolate batter in three batches.
Visual Cue: The final batter should be highly aerated, light in texture, and uniform in color without white streaks.
4. Bake the Sponge
Spread the batter evenly into your prepared jelly roll pan. Use an offset spatula to smooth the surface, reaching all the way to the corners.
Bake for 10 to 12 minutes. The cake is done when the top springs back slightly when gently pressed with your finger.
5. The Hot Roll Technique
Immediately turn the hot cake out onto your cocoa-dusted kitchen towel. Carefully peel off the parchment paper from the bottom of the cake.
While the cake is still steaming hot, roll it up tightly from the short end, rolling the towel inside the cake. Let it cool completely on a wire rack for exactly 1 hour.
6. Prepare the Peanut Butter Vanilla Cream
While the cake cools, beat the softened cream cheese and creamy peanut butter in a bowl until completely smooth. Add the sifted powdered sugar and vanilla extract, beating until fully incorporated.
In a separate chilled bowl, whip the heavy cream until stiff peaks form. Gently fold the whipped cream into the peanut butter mixture until you have a thick, creamy, uniform filling.
7. Assemble the Roll
Carefully unroll the cooled chocolate sponge. It is normal if the ends curl slightly. Spread the peanut butter filling evenly over the surface, leaving a 1/2-inch border around the edges.
Gently re-roll the cake, this time without the towel. Wrap the finished roll tightly in plastic wrap and chill in the refrigerator for at least 2 hours to set the filling.
8. Ganache and Garnish
Place the dark chocolate chips in a heatproof bowl. Microwave the 1/3 cup of heavy cream until just simmering, then pour it over the chocolate. Let it sit for 2 minutes, then whisk until smooth and glossy.
Place the chilled cake roll on a wire rack over a baking sheet. Generously drizzle the melted dark chocolate ganache over the top, letting it drip down the sides.
Immediately sprinkle with powdered sugar, chopped peanut butter cup pieces, and crushed peanuts so they stick to the wet ganache. Transfer to a clean white plate for serving.
Expert Tips for Success
- Whip Whites Correctly: Ensure your bowl for whipping egg whites is completely free of grease, otherwise, they will not reach stiff peaks.
- Do Not Wait to Roll: You must roll the sponge while it is piping hot. If it cools flat, it will crack when you attempt to shape it.
- Chill Before Slicing: Slicing a warm or freshly filled cake roll will result in a messy spiral. Chilling firms the cream cheese filling for a clean, hyper-realistic slice.
- Use a Hot Knife: For perfect presentation, dip a sharp chef’s knife in hot water and wipe it dry between every single slice.
Storage & Reheating/Freezing
Because of the dairy-rich filling, this Peanut Butter Cup Chocolate Roll must be stored in the refrigerator. Keep it in an airtight container or tightly wrapped in plastic wrap for up to 4 days.
To freeze, wrap the un-garnished cake roll tightly in a layer of plastic wrap followed by aluminum foil. Freeze for up to 2 months. Thaw overnight in the refrigerator before adding the fresh ganache and garnishes.
What to Serve With This
This rich dessert commands the spotlight, making it the perfect finale for an impressive dinner. If you are planning an indulgent menu, start your evening with a cozy, savory dish like marry me chicken pasta or a comforting bowl of creamy mushroom tortellini.
For a complete dessert table spread at a holiday gathering, serve this cake roll alongside other decadent treats. It pairs beautifully with the rich, deep flavors of a mexican chocolate milk cake.

Frequently Asked Questions
Yes! Cake rolls are perfect make-ahead desserts. You can fill and roll the cake 1-2 days in advance. Keep it tightly wrapped in the fridge, and add the warm ganache just before serving.
It is highly recommended to use standard creamy peanut butter. Natural peanut butter tends to separate and can make your cream cheese filling oily or grainy.
Ensure the cake is fully chilled for at least 2 hours. Run a sharp chef’s knife under hot water, wipe it completely dry, and make your slice. Clean the knife between every cut.
Cracking happens when the cake cools flat before rolling or is overbaked. You must roll the cake in a cocoa-dusted towel while it is piping hot from the oven so it ‘memorizes’ the spiral shape.
