- Preheat oven to 350 degrees F (175 degrees C). Grease and flour two 9 inch, round, cake pans; cover bottoms with waxed paper.
- In a large bowl, combine flour, 2 cups sugar, cocoa, baking powder, baking soda, and salt. Add eggs, milk, oil, and 1 tablespoon vanilla; beat until well blended. Pour batter into prepared pans.
- Bake for 35 minutes, or until wooden toothpick inserted in centers comes out clean. Cool layers in pans on wire racks 10 minutes. Loosen edges, and remove to racks to cool completely.

Gently brush loose crumbs off top and side of each cake layer with pasty brush or hands. To assemble, place one cake layer on cake plate. Spread with 1 cup frosting; top with 3/4 cup cherry topping. Top with second cake layer; repeat layers of frosting and cherry topping. Top with third cake layer. Frost side of cake. Pat reserved crumbs onto frosting on side of cake. Spoon reserved frosting into pastry bag fitted with star decorator tip. Pipe around top and bottom edges of cake. Spoon remaining cherry topping onto top of cake.
