Scale
For the Cake:
- 3/4 cup all-purpose flour
- 1/4 cup cocoa powder
- 1 teaspoon baking powder
- 1/4 teaspoon salt
- 3 large eggs
- 1 cup granulated sugar
- 1/3 cup water
- 1 teaspoon vanilla extract
For the Filling:
- 2 cups powdered sugar

- 1/4 cup heavy whipping cream
- 1/2 cup chopped peanut butter cups
For the Topping:

Instructions
- Prepare Your Workspace: Preheat oven to 375°F (190°C). Line a 15x10 inch jelly roll pan with parchment paper and grease thoroughly.
- Create the Cake Base: Sift together flour, cocoa powder, baking powder, and salt in a medium bowl. In a separate large bowl, beat eggs until they become thick and pale yellow, about 3 minutes.
- Mix Wet Ingredients: Gradually add sugar to the beaten eggs, followed by water and vanilla extract. Mix until well combined and slightly fluffy.
- Combine Carefully: Gently fold the dry ingredients into the wet mixture until just combined. Avoid overmixing to maintain the cake's light texture.
- Bake to Perfection: Spread the batter evenly in the prepared pan. Bake for 12-15 minutes, or until the cake springs back when lightly touched.
- Roll While Warm: Immediately invert the cake onto a clean kitchen towel dusted with powdered sugar. Carefully peel off the parchment paper and roll the cake up in the towel, starting from the short end.
- Cool Completely: Let the rolled cake cool on a wire rack while preparing the filling.
- Prepare Filling: Beat together powdered sugar, peanut butter, softened butter, and heavy cream until smooth and creamy. The mixture should be spreadable but firm.
- Fill and Roll: Unroll the cooled cake and spread the filling evenly, leaving a 1/2-inch border. Sprinkle with chopped peanut butter cups and carefully re-roll (without the towel).
- Finish and Chill: Wrap the rolled cake in plastic wrap and refrigerate for at least one hour. Before serving, drizzle with chocolate ganache.
