This dessert is a delightful treat for any occasion.

Ingredients

Scale
  • **For the Chocolate Cake:**
  • 1/2 cup all-purpose flour
  • 1/2 cup unsweetened cocoa powder
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 4 large eggs, separated
  • 1 cup granulated sugar, divided
  • 1 teaspoon vanilla extract
  • 1/4 cup milk
  • **For the Peanut Butter Filling:**
  • 1 cup creamy peanut butter
  • 1/2 cup unsalted butter, softened
  • 2 cups powdered sugar
  • 1/4 cup milk or heavy cream
  • 1 teaspoon vanilla extract
  • **For the Chocolate Ganache:**
  • 1 cup semi-sweet chocolate chips
  • 1/2 cup heavy cream
  • **For the Topping:**
  • 4–5 mini peanut butter cups, chopped
  • 2 tablespoons chopped roasted peanuts (optional)

Instructions

  1. **Prepare the Chocolate Cake:** Preheat oven to 375°F (190°C). Grease a 10×15-inch jelly roll pan and line with parchment paper, allowing an overhang on the sides. Grease the parchment paper.
  2. In a medium bowl, whisk together flour, cocoa powder, baking powder, and salt.
  3. In a large bowl, beat egg yolks with 1/2 cup granulated sugar until light and fluffy. Stir in vanilla extract and milk. Gradually add the dry ingredients, mixing until just combined.
  4. In a separate clean bowl, beat egg whites until soft peaks form. Gradually add the remaining 1/2 cup granulated sugar, beating until stiff, glossy peaks form.
  5. Gently fold one-third of the egg whites into the chocolate batter to lighten it, then carefully fold in the remaining egg whites until no streaks remain. Pour the batter evenly into the prepared pan.
  6. Bake for 12-15 minutes, or until the cake springs back when lightly touched.
  7. While the cake is baking, lay a clean kitchen towel on a flat surface and dust generously with powdered sugar.
  8. Immediately upon removing the cake from the oven, invert it onto the prepared towel. Carefully peel off the parchment paper. Trim any crisp edges if necessary.
  9. Starting from a short end, carefully roll the warm cake and towel together. Place seam-side down on a wire rack and let cool completely.
  10. **Prepare the Peanut Butter Filling:** In a medium bowl, beat softened butter and peanut butter until smooth. Gradually add powdered sugar, mixing until combined. Add milk or cream and vanilla extract, beating until light and fluffy.
  11. **Assemble the Roll:** Once the cake is completely cool, carefully unroll it. Spread the peanut butter filling evenly over the cake, leaving a 1-inch border on one short end.
  12. Carefully re-roll the cake, starting from the short end with the filling. Place the roll seam-side down on a serving platter.
  13. **Prepare the Chocolate Ganache:** In a small saucepan, heat heavy cream over medium heat until it just begins to simmer. Remove from heat and pour over chocolate chips in a heatproof bowl. Let stand for 5 minutes, then whisk until smooth and glossy.
  14. Pour the warm ganache over the chocolate roll, allowing it to drip down the sides.
  15. Garnish immediately with chopped peanut butter cups and chopped roasted peanuts, if using.
  16. Refrigerate for at least 1 hour to allow the ganache to set and the roll to firm up before slicing and serving.

Notes

Rolling the cake while warm prevents cracking. Dusting the towel with powdered sugar helps prevent sticking.

Ensure the cake is completely cool before unrolling and filling to prevent the filling from melting.

For a smoother ganache, ensure the cream is hot enough to melt the chocolate completely.

Chilling the finished roll makes for cleaner slices.

Adjust the amount of milk in the peanut butter filling to achieve your desired consistency.
