This website is fantastic! Great tips on simple decorating ideas to baking hints plus for the majority, they don't use that roll out icing, just butter icing. Great for the novice (but creative) baker. Great example is the number 3 cake or the one pictured. Highly recommend this, even if just for a giggle.
Before frosting, make sure your cake is shorter than a kit-kat bar, if not trim some off the top to leave room for the M’s. Frost and take a bunch of kit-kat bars (about 4 large packages), cut or gently break each bar into two sections. Place the bars on the cake, gently pushing into the frosting. Tie with a ribbon and fill the center with M’s (about 1 large bag). This cant be good.
