I saw this cake idea on Recipe Girl and absolutely had to make it. It is such a fun looking cake and so easy to make.
There are so many different variations you could do. I think it would make a fun groom's cake or even the top tier to a wedding cake, using white chocolate kit kats and M&M's the color of the bridesmaid dresses. Or you could put something in the top besides m&ms, like crushed up pieces of your favorite candy bar or flowers. The possibilities are endless.
I wish I could dive into that pool of M&M's.
