Step 2: Make the Cake Batter. In a bowl, whisk together flour, baking powder, and salt. In another large bowl, beat softened butter and sugar until light and fluffy (about 3–4 minutes).

Preparation. Make the cake: 1. Preheat the oven to 350 F. Grease the bottom and sides of 2 8-inch round or square baking pans with nonstick baking spray or butter.

Ladle 1 cup of each cake batter into each of the 3 pans: one with yellow cake, one with chocolate cake, and one with spice cake. 4. Lift each pie out of its pan using the foil overhangs.
