Rainbow Cake With Clouds Recipes

Steps:

• Preheat the oven to 400 degrees F (200 degrees C). Grease six 9-inch round cake pans and dust with flour.
• Sift together the flour, baking powder, and baking soda.
• Beat 3/4 cup plus 2 tablespoons butter, milk, sugar, egg whites, and vanilla extract in a large bowl with an electric mixer until smooth. Stir in flour mixture and mix until just combined.
• Divide cake batter evenly between 6 bowls. Mix in different food coloring to each bowl, creating 6 different colored batters. Start with just 1 to 2 drops of food coloring in each bowl, then mix; you can always add more.
• Bake each cake in the preheated oven, until a toothpick inserted in the center comes out clean, 15 to 20 minutes. Set aside to cool.
• Beat cream in a chilled glass or metal bowl with an electric mixer until stiff peaks form. Stir together confectioners' sugar and mascarpone cheese in a separate bowl, then fold gently into the whipped cream until smooth.
• Spread frosting on each layer of cooled cake, placing one on top of the other. Cover the top and sides with the remaining frosting. Refrigerate for 2 hours before serving.

Steps:

• 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.
• Combine the strawberries, water, sugar and lemon juice in a saucepan and cook over medium heat until the sugar is dissolved and the strawberries are quite soft. Puree the mixture in a blender. Strain through a fine strainer and cool.
