2regular packages or one large 8oz package of M&Ms - regular or peanut butter kind
Instructions
Prepare two 8" round cake pans by rubbing the inside bottom and sides with the 1 tbsp softened butter. Spoon some flour in each cake pan and shake it around making sure that some flour coats all the bottom and sides of both pans. Shake the excess flour out of the cake pans.
Preheat the oven to 350F.
Mix together the cake mix with the eggs, milk and oil. Pour the cake batter evenly in the two prepared cake pans.
Bake for 30-35 minutes or until a toothpick comes out clean when stuck in the middle of the cake. Cool for 15 minutes.
Make the peanut butter frosting by creaming together the butter and peanut butter with an electric mixer. Beat in the confectioner's sugar. Slowly beat in the milk until it reaching a smooth spreadable consistency.
Carefully remove the cakes from the cake pans. Using a long serrated knife, cut the rounded top off the two cakes.
Place one round cake, cut side up, on a cake stand/tray. Spread some of the frosting on the top of the cake. Make sure that the frosting is an even 1/2 inch layer. Place the second round cake, cut side down, on top of the first cake. Spread the remaining frosting on the top and sides of the cake.
Sprinkle the M&Ms across the top of the frosted cake.
