Scale
- For the Chocolate Sponge Cake:
- 4 large eggs
- 3/4 cup granulated sugar
- 1 teaspoon vanilla extract
- 1/2 cup all-purpose flour
- 1/4 cup unsweetened cocoa powder
- 1 teaspoon baking powder
- 1/4 teaspoon salt
- 2 tablespoons milk
- 2 tablespoons unsalted butter, melted
- For the Rainbow Cream Filling:
- 1 1/2 cups heavy whipping cream
- 1/4 cup powdered sugar
- 1 teaspoon vanilla extract
- Gel food coloring (assorted colors)
Instructions
- Preheat oven to 350°F (175°C). Line a 10×15-inch jelly roll pan with parchment paper and lightly grease.
- In a bowl, beat eggs and sugar until pale and fluffy. Add vanilla extract and mix well.
- Sift together flour, cocoa powder, baking powder, and salt. Gently fold into the egg mixture.
- Add melted butter and milk, mixing just until combined and smooth.
- Pour batter into the prepared pan and spread evenly. Bake for 10–12 minutes or until cake springs back when touched.
- Immediately invert the cake onto a clean kitchen towel dusted with powdered sugar. Remove parchment and roll the cake with the towel while warm. Let cool completely.
- Whip heavy cream with powdered sugar and vanilla until stiff peaks form.
- Divide whipped cream into separate bowls (5–6) and tint each with a different gel food color.
- Unroll the cooled cake and spread or pipe the colored creams in even stripes or swirls across the cake surface.
- Re-roll the cake tightly and chill for at least 1 hour before serving.
- Optional: Dust with powdered sugar or drizzle with chocolate before slicing.
Notes
- Roll the sponge while warm to prevent cracking.
- Gel food coloring is ideal to maintain cream texture.
- Swirl the colors slightly for a marble effect instead of stripes.
- Add a thin layer of jam under the cream for extra flavor.
- Use buttercream for a richer filling and more structure.
