Tender chocolate sponge rolled around a fluffy peanut butter filling makes this Reese’s roll cake feel like a bakery showpiece, even though it comes together with just a mixer and a few bowls. Every slice delivers cocoa-rich cake, a silky peanut butter swirl, and a glossy chocolate ganache finished with crunchy chopped peanut butter cups (and a little warm peanut butter drizzle, because why not). Serve it dusted with powdered sugar and a scoop of vanilla ice cream.

What Is Reese’s Peanut Butter Cup Roll Cake?

Reese’s Peanut Butter Cup Roll Cake is a light, cocoa-rich sponge baked in a thin sheet, rolled up while still warm in a powdered sugar-dusted towel, then unrolled once cool and spread with a fluffy peanut butter filling. Rolling it warm “trains” the cake to curl without cracking, and room-temperature eggs whip up airy enough to keep it tender and flexible. After a second roll, the cake gets a glossy chocolate ganache, a sprinkle of chopped peanut butter cups, and a drizzle of warmed peanut butter. It looks bakery-worthy, but it’s very doable at home, even if you’re a confident beginner moving into intermediate baking.

Ingredient Notes

The right ingredients make the difference between a roll cake that bends beautifully and one that cracks. Each item below plays a specific role in building the airy sponge, silky filling, and glossy topping of this Reese’s Peanut Butter Cup Roll Cake.

Quick note: Set out the eggs, butter, and cream before starting, and measure everything first. Roll cake batter moves fast once it’s mixed.

For the Chocolate Cake

• Large eggs (room temperature) : Eggs provide the structure and lift, since there’s no chemical leavening doing the heavy lifting here. Room-temperature eggs whip to greater volume, so if they’re cold, set them in warm tap water for 5 to 10 minutes.
• Granulated sugar : Sugar sweetens the cake and stabilizes the whipped eggs for a fine, tender crumb. Beat it in until the batter is pale and thick enough to leave a ribbon trail on the surface.
• Vegetable oil : Oil keeps the sponge soft and flexible, even after chilling, which is exactly what a rollable cake needs. Butter can make the cake firmer when cold, so any neutral oil, like canola, is the better choice.
• Vanilla extract (cake) : Vanilla rounds out the cocoa and adds a bakery-style aroma. Pure vanilla extract has a deeper flavor than imitation, and it’s worth using in a recipe with so few ingredients.
• All-purpose flour : Flour gives just enough structure to hold the roll together. Spoon it into the measuring cup and level it off, because scooping packs in extra flour and leads to a dry, crack-prone cake.
• Unsweetened cocoa powder : Cocoa delivers the deep chocolate flavor and dark color. Sift it with the flour to avoid bitter lumps, and use either natural or Dutch-process for a rich result.
• Baking powder : A small amount adds a little extra lift to keep the sponge light. Check that the date is current, since old baking powder loses its power and leaves the cake flat.
• Salt : Just a pinch sharpens the chocolate and balances the sweetness. Fine salt disperses evenly in a thin batter like this one.
• Powdered sugar (for dusting the towel) : This keeps the warm cake from sticking to the towel while it’s rolled. Use a smooth, lint-free kitchen towel and dust it generously, since cocoa-dark cakes can cling more than expected.

For the Peanut Butter Filling

• Unsalted butter (softened) : Butter makes the filling fluffy, creamy, and spreadable. It should be soft but still cool, around 65°F, so a finger press leaves a dent without sinking in or looking greasy.
• Creamy peanut butter : This is the star of the filling, bringing roasted, salty-sweet flavor and a silky texture. Standard creamy brands like Jif or Skippy hold up best, while natural styles can separate and make the filling loose or oily.
• Powdered sugar : It sweetens and stabilizes the filling without any gritty texture. Sift it first so the filling stays smooth and spreads without tearing the delicate cake.
• Heavy cream (filling) : A couple of tablespoons loosen the filling and make it light and spreadable. Add it gradually and stop once the filling is fluffy, because too much can make it too soft to hold its shape in the roll.
• Vanilla extract (filling) : Vanilla softens the richness of the peanut butter and adds a rounded, bakery-style sweetness. Use the same pure extract as in the cake for consistent flavor.

For the Topping

• Semisweet chocolate chips : These melt into a glossy ganache with just enough bittersweet balance for the sweet filling. Chips contain stabilizers that help them hold their shape, so for an extra-silky finish, a chopped semisweet baking bar works nicely too.
• Heavy cream (ganache) : Cream turns the chocolate into a smooth, pourable glaze. Heat it until steaming (not boiling), pour it over the chips, and let it sit for 2 minutes before stirring to avoid a grainy texture.
• Chopped Reese’s Peanut Butter Cups : They add salty-sweet crunch and a recognizable candy-shop finish. Chill or freeze them for 10 minutes before chopping for cleaner pieces, and sprinkle them over the ganache while it’s still slightly tacky so they stay put.
• Creamy peanut butter (gently warmed, for drizzling) : A quick warm-up turns it into a ribbon-like drizzle for a pretty finish and extra peanut flavor. Microwave it in 10-second bursts, stirring between each, until it flows easily from a spoon without becoming hot or oily.

Step-by-Step Instructions

• Heat the oven to 350°F and line a 10×15-inch jelly roll pan with parchment paper, then lightly grease the parchment. Sift the flour, cocoa powder, baking powder, and salt together in a bowl, and lay a clean, lint-free towel on the counter, dusted generously with powdered sugar.
• Beat the room-temperature eggs and granulated sugar with an electric mixer on medium-high for 4 to 5 minutes, until pale, thick, and ribbons of batter hold on the surface for a few seconds. Drizzle in the vegetable oil and vanilla extract and mix just until combined.
• Fold the sifted dry ingredients into the whipped eggs with a spatula, using slow sweeps from the bottom of the bowl until no streaks remain. Spread the batter evenly in the pan and bake for 10 to 12 minutes, until the top springs back when lightly pressed. I pull it out right at that point, because an extra minute can make the edges brittle.
• Run a knife around the edges and flip the warm cake onto the prepared towel, then peel off the parchment. Roll the cake up in the towel, starting from a short end, and let it cool seam side down for about 30 minutes. It’s normal for it to look a little squished, since this step teaches the sponge to curl without cracking.
• Beat the softened butter and creamy peanut butter on medium speed for about 2 minutes, until smooth and lightened. Add the sifted powdered sugar, heavy cream, and vanilla extract, then whip for 1 to 2 minutes, until the filling is fluffy and spreadable.
• Unroll the cooled cake gently and spread the peanut butter filling over the surface, leaving a 1-inch border along the edges. Roll it back up without the towel, tucking the first turn in snugly, then place it seam side down on a platter and chill for 30 minutes to firm up.
• Heat the heavy cream in a small saucepan until steaming but not boiling, then pour it over the semisweet chocolate chips and let it sit for 2 minutes. Stir until glossy and smooth, spoon the ganache over the chilled roll, and scatter the chopped Reese’s Peanut Butter Cups on top while the ganache is still tacky. I like to finish with the gently warmed peanut butter, drizzled in thin zigzags with a spoon.
• Chill the finished roll for 15 to 20 minutes so the ganache sets, then slice with a sharp knife , wiping the blade clean between cuts. I serve it dusted with powdered sugar and a scoop of vanilla ice cream alongside.

Tip: If the cake develops a small crack while rolling, don’t worry. The ganache and candy topping cover it beautifully, and the flavor won’t be affected.

Quick reminder: Roll the cake while it’s still warm, and keep the filling at a soft, spreadable consistency so it doesn’t tear the sponge.

Make Ahead Options

This Reese’s Peanut Butter Cup Roll Cake is a dream for meal prep, because you can bake and fill it up to 24 hours in advance and save the fun part for serving day. Bake the sponge, roll it in the powdered sugar-dusted towel, and let it cool completely, then spread on the peanut butter filling, re-roll, wrap tightly in plastic, and refrigerate overnight (this keeps the sponge soft and prevents drying). Before serving, warm the ganache, pour it over the chilled roll, and add the chopped peanut butter cups and warmed peanut butter drizzle. Can I make this ahead of time? Absolutely, and it’s just as delicious, with up to 3 days of fridge storage once finished.

Variations & Substitutions

This Reese’s Peanut Butter Cup Roll Cake is easy to adjust for dietary needs, pantry gaps, or your own taste. Here are a few tested tweaks that keep the sponge flexible and the filling silky.

• Gluten-free version : Swap the all-purpose flour for a 1:1 gluten-free baking blend that contains xanthan gum, and keep the folding gentle so the sponge stays flexible.
• Dairy-free ganache : Use full-fat canned coconut milk instead of cream and dairy-free chips; top with roasted peanuts, since Reese’s cups contain milk.
• Lighter filling : I sometimes replace the 2 tablespoons of heavy cream in the filling with whole milk; it spreads just as smoothly, with slightly less richness.
• Bittersweet ganache option : Use 60% cacao bittersweet chips instead of semisweet for a less sweet topping that balances the sugary peanut butter filling.
• Deeper chocolate flavor : I stir ½ teaspoon of instant espresso powder into the dry ingredients; it amplifies the cocoa without making the cake taste like coffee.
• Swap the candy : Chopped Reese’s Pieces, or salted roasted peanuts with a pinch of flaky sea salt, give similar crunch if you can’t find peanut butter cups.

Serving Suggestions

• Slice and plate it with care: Chill the roll until the ganache is fully set, then slice it with a sharp knife and wipe the blade clean between cuts for neat spirals. Cut 1-inch slices, which give you 8 generous servings, and lay each one on its side so the swirl shows. I dust each plate with powdered sugar just before serving, then add a scoop of vanilla ice cream beside the slice, not on top, so it doesn’t melt into the ganache. Let the slices sit for 20 to 30 minutes at room temperature first. The filling turns creamy and the ganache regains its shine.
• Cut the richness with something bright or bitter: Chocolate, peanut butter, and ganache make a very rich dessert, so pair it with something that cleanses the palate. A handful of fresh raspberries or sliced strawberries adds tartness, and a spoonful of lightly sweetened whipped cream softens the intensity. For drinks, I reach for strong black coffee or espresso, whose bitterness balances the sweetness. Cold whole milk is the nostalgic choice for kids. For an after-dinner treat, a chocolate stout or a small pour of tawny port complements the roasted peanut and cocoa flavors.
• Match the portion to the occasion: For a dinner party, serve thinner half-inch slices with a spoonful of berries and a drizzle of warmed peanut butter. The roll is rich, so smaller portions feel elegant and satisfying. For potlucks, birthdays, or holiday dessert tables, set the whole roll on a platter, scatter extra chopped Reese’s cups around it, and slice at the table so guests can see the spiral.
• Plan ahead for easy entertaining: The roll is best made a day ahead, since the overnight chill makes slicing cleaner. Keep the powdered sugar and peanut butter drizzle for the last minute so the finish looks fresh. Leftover slices also make a quick weeknight treat with a hot cup of coffee.

Expert Tips

Here are a few things I’ve learned that make a Reese’s Peanut Butter Cup Roll Cake turn out right every time.

• Whip eggs fully : Beat the eggs and granulated sugar the full 4 to 5 minutes; the thick ribbon stage creates most of the sponge’s lift.
• Fold, don’t stir : I fold the sifted flour and cocoa in with slow sweeps from the bottom, because stirring deflates the eggs and gives a dense, crack-prone roll.
• Soften butter properly : Use unsalted butter that’s cool but pliable, around 65°F; overly warm butter turns the peanut butter filling greasy and too loose to roll.
• Chill before chopping : Freeze the Reese’s cups for 10 minutes before chopping so they cut cleanly instead of smearing, and sprinkle them while the ganache is tacky.
• Let ganache rest : I pour steaming heavy cream over the semisweet chocolate chips and wait 2 minutes before stirring; that pause gives a glossy, smooth finish without graininess.

Storage & Freezing

• Refrigerating: Store leftover Reese’s Peanut Butter Cup Roll Cake in an airtight container, or wrap it snugly in plastic wrap, for up to 3 days. Press a piece of plastic against any cut ends so the filling doesn’t dry out or pick up fridge odors. Because the filling is made with butter and cream, don’t leave the cake out for more than 2 hours. The oil-based sponge stays soft and rollable in the cold, but the ganache will firm up and look a bit dull.
• Freezing: Wrap the whole roll tightly in plastic, then foil, and freeze for up to 2 months. For single servings, freeze slices on a parchment-lined tray for about an hour, then wrap each one individually. The sponge and peanut butter filling freeze very well. The chopped Reese’s cups turn a little chewier after thawing, and the powdered sugar dusting and warm peanut butter drizzle don’t hold up, so I add those fresh. If I know I’m freezing the whole roll, I sometimes skip the toppings and finish it the day I serve it.
• Thawing and serving: Thaw the cake in the refrigerator , still wrapped, for 6 to 8 hours or overnight, so condensation doesn’t make the ganache sweat. Then let it sit at room temperature for 20 to 30 minutes. This softens the filling and brings back the ganache’s shine. Skip the microwave for the whole roll. If a single slice feels too firm, 5 to 8 seconds is plenty before the filling starts to melt.
• Reviving leftovers: To freshen a slice, dust it with powdered sugar and drizzle on a little peanut butter warmed in 10-second bursts, stirring between each. A scoop of vanilla ice cream alongside makes a day-two slice feel just as indulgent as the first.
