STEP 3: Crumb coat the cake by applying a thin layer of frosting to top and sides that will keep crumbs from getting caught in the final frosting. Place cake in the fridge for 5 to 10 minutes, or until the crumb coat has set.
STEP 4: Cover cake with remaining frosting, starting with a generous amount on top and working toward edges. Apply frosting to sides and use the spatula to create a clean edge. Clean frosting off spatula with each pass to help create a smooth finish. A warm spatula will also help keep the frosting smooth.
CIRCUS DECORATION: Decorate the top with sprinkles. You can keep the sides smooth or, if you prefer a textured edge, use a smaller spatula or knife to create a pattern. Place cookies around the cake in alternating colors and a few grazing on top.
CHOCOLATE TIRE: For chocolate lovers, this simple decoration also gives you a guide for slicing. Apply fudge sticks to sides and a chocolate kiss on top and everyone gets their own.
