Baby Shower Cake

Heat oven to 350°F (325°F for dark or nonstick pans). Grease bottoms only of three 8-inch or 9-inch round pans.

Make cake batter as directed on box. Pour 1 1/2 cups of the batter into small bowl. Pour another 1 1/2 cups of the batter into one of the pans.

Stir 6 to 10 drops red food color into batter in small bowl. Stir 6 to 10 drops blue food color into batter in large bowl. Pour pink batter into another pan; pour blue batter into remaining pan. (If necessary, refrigerate 1 pan of batter until ready to bake.)

Bake 8-inch pans 19 to 24 minutes, 9-inch pans 17 to 22 minutes, or until toothpick inserted in center comes out clean. Cool 10 minutes; remove from pans to cooling rack. Cool completely, about 1 hour.

Place blue layer, top side down, on plate. Spread 1/3 cup frosting on blue layer almost to edge. Place white layer, top side down, on frosted layer. Spread 1/3 cup frosting on white layer almost to edge. Place pink layer, top side up, on frosted layer. Frost side and top of cake with remaining frosting. Store loosely covered.
