Thanks to pinterest, I found the perfect cake! And even better? I could make it myself for far less than having one made. More importantly, it involved both Cowboy's and my father-in-law's favorite candy. A win on all levels! The original Kit Kat Cake was full of bright colors and would be perfect for a rainbow party, but you can adapt this however you like. I also saw a picture with graham cracker sticks as the border which would also be fun; however, if there was a possibility of Kit Kats in this house and then none showed up, well, there might have been some trouble!
Sorry I don't any step-by-step photos. Again, the mad rush of the day (and day before) got in the way of my photography!
I broke apart the Kit Kat bars into twos and used 4 large packages of them. I did have to cut the bars down with a knife so they weren't too tall. Be sure to make the bars tall enough to serve as a border for the M&Ms so they don't fall off the cake.
After you're surrounded the cake with the bars, cover with the M&Ms and tie a ribbon around to keep everything in place. Cutting was easy. (At least I think so, right Mom?). Just but between every two bars. This also leaves you with plenty cake!
