- 1 10 1/2 by 15 1/2 by1-inch sheet cake made with basic white cake in a buttered pan lined with parchment paper.
- 2 recipes Vanilla Buttercream divided into 5 bowls and colored red, orange, yellow, blue and green.
- 1 recipe Strawberry Coulis in a squeeze bottle, recipe follows
- 3 cups whipped cream
- Confetti sprinkles
Remove the cake from the pan and leave it on the parchment paper. Using the colored buttercream, spread stripes of the frosting lengthwise on the cake. Using parchment to lift and push forward, roll the cake lengthwise as tightly as possible. Once the cake is rolled, place on a large platter, seam side down. Shortly before serving, frost the cake with the whipped cream. Spread the whipped cream on generously and create swirls using a palette knife. To make the cloud-like swirls, lightly drag the palette knife through the whipped cream and gently pull up to make peaks. Decorate the platter outside of the cake with strawberry coulis and sprinkle the whole thing with confetti sprinkles. As the cake is sliced, a "rainbow" of frosting will be revealed on the inside.
