Mix 6 lbs of cake mix according to the bag, BUT add 5 oz of DDA® Coffee Flavor to the batter. Bake cake layers according to directions on bag. Allow cake layers to cool completely. Mix 2 oz of DDA® Coffee Flavor to 3 lbs of Dawn Exceptional® White Buttercreme Style Icing. Cut each cake layer into two pieces of even size. Begin layering by spreading a layer of Coffee Buttercreme Style Icing over a cut cake layer, making sure to keep it even. Place another cut cake layer on top of the buttercreme style icing and spread the Dawn Select™ Fudge Cake Icing over the cake. Continue layering until desired height. Place the final layer of cake on top and ice with Dawn Select™ Fudge Cake Icing to desired thickness. Refrigerate for 1 hr before serving.
