Best Ever Buttercream Frosting | Before you begin covering your cake with fondant, be sure that your cake is covered with a layer of buttercream at least 1/4-inch thick. This frosting layer helps the fondant stick to the cake and smooths out any bumps or imperfections on the cake surface, so the fondant layer looks clean and smooth. And it's buttercream, so it tastes amazing, right?
