Instructions
Preheat oven to 350°F (175°C). Line a 10×15-inch jelly roll pan with parchment paper and lightly grease it.
- In a bowl, sift together flour, cocoa powder, baking powder, and salt.
- In a large bowl, beat eggs and sugar until thick, pale, and fluffy. Add oil, vanilla, and milk; mix until combined.
- Gently fold dry ingredients into wet mixture until just combined.
- Spread batter evenly in prepared pan. Bake 10–12 minutes, until cake springs back when lightly pressed.
- While warm, invert cake onto a clean towel dusted with powdered sugar. Peel off parchment, then roll cake in towel from short end. Let cool completely.
- Whip cream with powdered sugar and vanilla until stiff peaks form. Divide into 6 bowls and tint each with a different color.
- Unroll cooled cake and spread rainbow filling in horizontal lines across surface. Re-roll tightly.
- Refrigerate 1–2 hours to set.
- Optional: Top with chocolate ganache, powdered sugar, or sprinkles before slicing and serving.
Notes
- Add a thin layer of ganache before rainbow filling for extra richness.
- Use marshmallow filling instead of whipped cream for fluffier texture.
- Try a white sponge cake for brighter contrast.
- Use fruit-flavored extracts in whipped cream for variation.
- Sprinkle extra fun by adding rainbow sprinkles inside the roll.
