Instructions
Make the Chocolate Cake
- Preheat oven to 375°F (190°C). Grease a 15x10-inch jelly roll pan, line with parchment paper, and grease the paper.
- In a small bowl, whisk together flour, cocoa powder, baking powder, and salt.
- In a large bowl, beat egg yolks with 1/2 cup of sugar until light and fluffy. Beat in water and vanilla.
- Gradually add the flour mixture to the egg yolk mixture, mixing until just combined.
- In a separate clean bowl, beat egg whites until soft peaks form. Gradually beat in the remaining 1/2 cup of sugar until stiff, glossy peaks form.
- Gently fold one-third of the egg whites into the chocolate batter, then fold in the remaining whites until no streaks remain.
- Spread batter evenly into the prepared pan. Bake for 12-15 minutes, or until the cake springs back when touched.
Roll and Cool the Cake
- Immediately run a knife around the edges of the pan. Invert the warm cake onto a clean kitchen towel dusted with powdered sugar.
- Carefully peel off the parchment paper. Starting from a short end, roll up the cake and towel together. Let cool completely on a wire rack.
Prepare Filling and Assemble
- In a medium bowl, beat cream cheese and peanut butter until smooth. Beat in powdered sugar and vanilla.
- Fold in the whipped topping until well combined.
- Gently unroll the cooled cake. Spread the filling evenly over the cake, leaving a 1/2-inch border. Reroll the cake tightly without the towel.
Make the Ganache and Finish
- Place chopped chocolate in a heatproof bowl. Heat the heavy cream until it just begins to simmer, then pour over the chocolate. Let stand for 5 minutes, then stir until smooth.
- Place the cake roll on a wire rack over a baking sheet. Pour the ganache over the cake, spreading to cover. Refrigerate for at least 1 hour to set before slicing and serving.
Notes
For the cleanest slices, use a hot, dry knife. Dip the knife in hot water and wipe it clean between each cut.
Ensure the cake is completely cool before unrolling and adding the filling to prevent melting.
