Ingredients
Scale
- 4 large eggs (room temperature)
- 1/2 cup granulated sugar
- 1/4 cup unsweetened cocoa powder
- 1/4 cup all-purpose flour
- 1 tsp baking powder
- 1/4 tsp salt
- 1 tsp vanilla extract
- 1 1/4 cups heavy cream (chilled)
- 1/3 cup powdered sugar
- 1 tsp vanilla extract
- Food coloring gels (red, orange, yellow, green, blue, purple)
- 1 cup semi-sweet chocolate chips
- 1/2 cup heavy cream (warm)
- Rainbow sprinkles
Instructions
- Preheat oven to 350°F (175°C). Line a 10×15-inch jelly roll pan with parchment paper.
- In a bowl, beat eggs and sugar with an electric mixer until thick and pale (5 minutes).
- Sift together flour, cocoa powder, baking powder, and salt. Gently fold into the egg mixture.
- Add vanilla extract. Spread batter evenly in the prepared pan.
- Bake for 10–12 minutes, until springy to the touch.
- While warm, turn the cake onto a clean kitchen towel dusted with powdered sugar.
- Peel off parchment paper. Roll cake up in the towel (starting from the short side). Let cool completely.
- Beat heavy cream, powdered sugar, and vanilla until stiff peaks form.
- Divide into 6 bowls and tint each with a different food color.
- Spread dollops of each colored cream in rows across the unrolled cake. Use a spatula to lightly swirl colors for a rainbow effect.
- Gently re-roll the cake with filling inside. Wrap in plastic wrap and refrigerate 1 hour to set.
- Make ganache by pouring warm cream over chocolate chips, whisking until smooth.
- Spread ganache over the roll. Top with rainbow sprinkles.
Notes
- Ensure the eggs are at room temperature for better volume.
- Use a clean towel to prevent sticking when rolling the cake.
- Chill the cake after assembling to help it hold its shape.
