Ingredients:

• For the Chocolate Sponge Cake:

  • 1 cup (120g) all-purpose flour, sifted
  • ¾ cup (75g) unsweetened cocoa powder, natural or Dutch-processed, sifted
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • 5 large eggs, at room temperature, separated (yolks and whites)
  • 1 cup (200g) granulated sugar, divided into ½ cup portions
  • ½ cup (120ml) milk, whole milk preferred, at room temperature
  • ½ cup (120ml) vegetable oil, or any neutral-flavored oil
  • 1 teaspoon vanilla extract
  • ¼ cup (60ml) hot water or freshly brewed hot coffee (for deeper chocolate flavor)

• For the Peanut Butter Filling:

  • 1 cup (226g) unsalted butter, softened to room temperature
  • 1 cup (250g) creamy peanut butter (not natural style, as it can separate)
  • 4-5 cups (480-600g) powdered sugar, sifted, depending on desired sweetness and consistency
  • ½ teaspoon salt (if using unsalted peanut butter)
  • ½ cup (120ml) heavy cream, cold
  • 1 teaspoon vanilla extract

• For the Chocolate Ganache:

  • 1 ½ cups (255g) good quality semi-sweet chocolate chips or chopped chocolate
  • 1 cup (240ml) heavy cream
  • 2 tablespoons (28g) unsalted butter, softened (optional, for extra sheen and richness)
  • 1 teaspoon vanilla extract (optional)

• For Garnish:

  • 10-12 mini peanut butter cups, chopped or whole, for decoration
  • Optional: a drizzle of melted peanut butter or chocolate for extra flair

For the Chocolate Sponge Cake:

1. Prepare your baking area: I always start by preheating my oven to 350°F (175°C). Then, I line a 10×15-inch (25×38 cm) jelly roll pan with parchment paper, ensuring it overhangs on the sides to create “handles” for easy removal later. Lightly grease the parchment paper with a little baking spray or butter; this simple step makes a huge difference in preventing sticking and ensures your beautiful chocolate sponge releases perfectly.
2. Combine dry ingredients: In a medium bowl, I whisk together my sifted all-purpose flour, sifted unsweetened cocoa powder, baking powder, baking soda, and salt. Sifting is crucial here to prevent any lumps, guaranteeing a smooth and uniform texture for our delicate cake. Set this dry mixture aside for a moment.
3. Prepare the wet ingredients (yolks): In a separate large bowl, I combine the egg yolks with ½ cup of the granulated sugar. Using an electric mixer, I beat these until the mixture becomes pale yellow and thick, almost ribbon-like when you lift the beaters. This process incorporates air and dissolves the sugar, which contributes significantly to the cake’s light structure.
4. Add remaining wet ingredients: To the egg yolk mixture, I gently whisk in the room temperature milk, vegetable oil, vanilla extract, and the hot water (or hot coffee, for that profound chocolate depth). Mix until everything is just combined. The hot liquid helps to bloom the cocoa powder, intensifying its flavor and making the chocolate notes truly sing in our “Peanut Butter Cup Chocolate Roll Cake.”
5. Fold in dry ingredients: Gradually add the dry ingredient mixture to the wet mixture, mixing on low speed until just combined. Be careful not to overmix at this stage; overmixing can develop the gluten too much, leading to a tough cake. We want our sponge to be tender and flexible for rolling.
6. Whip egg whites: In a very clean, separate large bowl (preferably a stand mixer bowl), I beat the egg whites with a clean whisk attachment on medium speed until they become foamy. Gradually add the remaining ½ cup of granulated sugar, one tablespoon at a time, while continuing to beat on high speed. Continue beating until the egg whites form stiff, glossy peaks. This means when you lift the whisk, the peak stands up straight and holds its shape without drooping. This aeration is key for a light, airy roll cake.
7. Gently fold whites into batter: Carefully fold about one-third of the whipped egg whites into the chocolate batter to lighten it up. Then, gently fold in the remaining egg whites in two additions, using a rubber spatula. The goal is to incorporate the whites without deflating them, preserving all that wonderful air. Use a gentle, lifting motion from the bottom of the bowl. You’ll see the batter transform into a beautifully airy and light consistency.
8. Bake the sponge cake: Pour the batter evenly into your prepared jelly roll pan. Gently spread it out to the corners using an offset spatula. Bake for 12-15 minutes, or until the cake springs back when lightly touched and a wooden skewer inserted into the center comes out clean. Do not overbake, as this can dry out the cake and make it prone to cracking when rolled.
9. Prepare for rolling: As soon as the cake comes out of the oven, immediately dust a clean kitchen towel (or another sheet of parchment paper) with a generous amount of powdered sugar. Invert the hot cake onto the prepared towel/parchment. Carefully peel off the parchment paper that was on the bottom of the cake. While the cake is still warm, starting from one of the short ends, tightly roll the cake up with the towel/parchment inside. Place the rolled cake, seam-side down, on a wire rack and allow it to cool completely to room temperature. This step “trains” the cake to hold its rolled shape, making it incredibly flexible and preventing cracks when you add the filling later. Patience here is truly a virtue!

For the Peanut Butter Filling:

1. Cream butter and peanut butter: In the bowl of a stand mixer fitted with the paddle attachment (or using a hand mixer), beat the softened unsalted butter on medium speed until it’s light and fluffy, about 2-3 minutes. Add the creamy peanut butter and continue beating until well combined and smooth, scraping down the sides of the bowl as needed. I find that using a good quality, regular creamy peanut butter (not the natural, oily kind) yields the best texture for this filling, ensuring it’s wonderfully stable and pipeable.
2. Gradually add powdered sugar: With the mixer on low speed, gradually add the sifted powdered sugar, one cup at a time, mixing until fully incorporated after each addition. If you’re using unsalted peanut butter, now is a good time to add that ½ teaspoon of salt; it really helps to balance the sweetness. The mixture will become quite thick.
3. Add heavy cream and vanilla: Pour in the cold heavy cream and vanilla extract. Increase the mixer speed to medium-high and beat for another 3-5 minutes, until the filling is incredibly light, fluffy, and smooth. The air incorporated here makes for a dreamily soft filling that complements the rich chocolate cake perfectly. Scrape down the bowl periodically to ensure everything is evenly mixed. This luscious peanut butter filling is a star component of our “Peanut Butter Cup Chocolate Roll Cake.”

For the Chocolate Ganache:

1. Prepare the chocolate: Place the semi-sweet chocolate chips or finely chopped chocolate in a medium, heatproof bowl. Chopping the chocolate into small, uniform pieces ensures even melting.
2. Heat the cream: In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer around the edges, but do not let it come to a rolling boil. It’s important not to scorch the cream.
3. Pour cream over chocolate: Immediately pour the hot cream over the chocolate in the bowl. Let it sit undisturbed for 5 minutes; this allows the residual heat from the cream to melt the chocolate gently.
4. Whisk until smooth: After 5 minutes, gently whisk the mixture starting from the center and working your way out, until the ganache is completely smooth and glossy. If you’re adding butter, whisk it in now until fully incorporated and melted. Stir in the vanilla extract, if using, for an extra aromatic touch.
5. Cool the ganache: Let the ganache cool at room temperature, stirring occasionally, until it reaches a thick, spreadable consistency, similar to frosting. This can take anywhere from 1 to 2 hours, or you can speed it up slightly by placing it in the refrigerator for 20-30 minute intervals, stirring frequently to ensure even cooling and to prevent it from setting too hard. The ideal consistency is crucial for an even coating on your roll cake.

Assembling the Peanut Butter Cup Chocolate Roll Cake:

1. Unroll the cooled cake: Once the chocolate sponge cake is completely cool and has “trained” itself, carefully unroll it from the towel/parchment paper onto a clean, flat surface. The cake should now be flexible and easy to handle. If you rolled it with parchment, you might find it easier to keep the cake on that piece of parchment to facilitate rolling it back up later.
2. Spread the peanut butter filling: With an offset spatula or the back of a spoon, spread the luscious peanut butter filling evenly over the entire surface of the chocolate sponge cake, leaving about a ½-inch border along one of the short ends. This ensures that the filling doesn’t squish out excessively when you roll the cake, creating a neat finish. Make sure the filling is evenly distributed for a balanced bite.
3. Roll the cake: Starting from the short end without the border, carefully and gently roll the cake back up tightly. Use the parchment paper or towel underneath to help you roll it into a snug log. Take your time to roll it as tightly as possible without cracking the cake, maintaining an even thickness.
4. Chill the roll cake: Transfer the rolled cake, seam-side down, to a serving platter or a baking sheet. Loosely cover it with plastic wrap and refrigerate for at least 30 minutes to 1 hour. This chilling time helps the filling to firm up, making the cake much easier to handle and preventing it from squishing when you apply the ganache and slice it. This firming step is vital for a structurally sound “Peanut Butter Cup Chocolate Roll Cake.”

Finishing and Decorating:

1. Frost with ganache: Once the roll cake is chilled and the ganache has reached a spreadable consistency, remove the cake from the refrigerator. Evenly spread the chocolate ganache over the entire surface of the cake using an offset spatula. You can make decorative swirls or keep it smooth, depending on your preference. I often like to create a slightly rustic, wavy texture with the back of my spatula.
2. Garnish with peanut butter cups: While the ganache is still wet, carefully arrange your chopped or whole mini peanut butter cups on top of the cake. You can place them artistically along the top, or scatter them generously. The combination of rich chocolate and creamy peanut butter cups is what makes this “Peanut Butter Cup Chocolate Roll Cake” so utterly irresistible. If desired, you can also drizzle a little extra melted peanut butter or chocolate over the top for an even more decadent look.
3. Chill again: For the neatest slices and to allow the ganache to set properly, return the decorated roll cake to the refrigerator for at least another 30 minutes, or until the ganache is firm to the touch. This makes a huge difference in presentation.
4. Serve: When ready to serve, use a sharp knife (dipped in hot water and wiped clean between each cut for the cleanest slices) to cut the Peanut Butter Cup Chocolate Roll Cake into individual portions. Each slice reveals a beautiful spiral of chocolate cake and creamy peanut butter filling, topped with that dreamy ganache and crunchy peanut butter cups. This cake is best enjoyed at room temperature or slightly chilled. Store any leftovers in an airtight container in the refrigerator for up to 3-4 days. I promise, it rarely lasts that long!

Elevate Your Serving Experience

To truly enhance your enjoyment of this decadent creation, consider some delightful serving suggestions. I love serving a generous slice of this roll cake with a small scoop of premium vanilla bean ice cream; the cool creaminess provides a wonderful contrast to the rich cake. Alternatively, a simple dusting of cocoa powder or a few fresh raspberries or strawberries can add a touch of elegance and a bright, tart counterpoint to the sweetness. For those who appreciate a textural crunch, a sprinkle of finely chopped roasted peanuts or even a few mini peanut butter cups on top of each slice just before serving can be absolutely divine. This cake also pairs beautifully with a steaming mug of strong black coffee, a frothy latte, or, for a simpler pleasure, a tall, cold glass of milk. It’s versatile enough to be enjoyed as the grand finale to an elaborate meal or as a casual afternoon pick-me-up. Don’t be afraid to experiment with your garnishes; presentation truly can elevate the entire experience.

Unleash Your Inner Baker: Variations to Try

And for those adventurous souls who love to put their own spin on things, I encourage you to explore some fun variations! For an extra burst of peanut butter goodness, try folding a handful of chopped mini peanut butter cups directly into the cream cheese filling before spreading it. You could also drizzle a little extra melted peanut butter over the ganache for an even more intense flavor and a visually appealing swirl. If you’re feeling bold, a tiny pinch of sea salt sprinkled over the top of the finished cake can truly make the flavors pop, enhancing both the chocolate and the peanut butter. For a different kind of ganache, consider using a milk chocolate or even a white chocolate version for a sweeter, creamier finish. Adding a touch of espresso powder to the cake batter itself can deepen the chocolate flavor beautifully without making it taste like coffee. The possibilities are truly endless, and this recipe provides the perfect canvas for your creative impulses.
