with the kit kat sides and M&M top, I was wondering what flavor cake you all use so as not to sickly sweet? I want it to look good but taste good as well.... What would you all recommend?

I did one a couple weeks ago for the first time. I had read on another thread about a cookie layer, and I tried that. My cake was 8" with 2 layers of devils food and a layer of peanut butter cookie. The peanut butter cookie really kept it from being too sweet I think.

I can't find that other thread ( of course) but I basically bought a Betty Crocker peanut butter cookie mix, mixed it up and baked it in the same 8" pan, then sandwiched it between the 2 layers of cake and filling. We cut the pieces small, 2 kitkats each, and it wasn't too sweet. Everyone loved it

now that sounds yummy...thanks so much for responding to me. Now that won't make it too high for kit kats with addition of cookie layer? Pat

Glad to help! I got the idea from someone on here, so I'm glad to pass it on! I used the regular KitKats that come 4 sticks to a package. They are about 4 inches. If you use the snack size or king size ones, they are shorter I think. What I did was bake a devil's food cake from box mix, and when it was cool I leveled it so each of the 2 layers was probably 1-1.5 inches. The cookie ended up being about the same. For filling, I just used chocolate frosting, so the filling layer wasn't too thick. When I got the cakes and cookie stacked up, the frosted with chocolate, there was maybe half an inch from the top of the cake to the top of the kitkats. There was plenty of room for the reeses pieces (or M&M's) I basically put one layer of the Reeses, then spread some loose ones over top of that to fill in any holes.

Here's the cake before it was cut:

If you have any more questions, I'm glad to help if I can! I'll keep looking to see if I can find the post that helped me! If so, I'll link it here!

Oh I found it! The info about the cookie is on page 2 by Andpotts (Andrea) And she tells how to does the cookie and cake. I found it really useful! Lots of good info in that post! I hope the link works...

thank you so much...you have been such a help. I was worried that a two layer cake with cookie would be too high.
