1. Kit Kat and M&M's Chocolate Cake
Approximate calorie count: 1,368 (...for one slice)

Somewhere underneath that sea of M&M's and Kit Kats is a full-on chocolate cake, with the candies held in place by buttercream. If that was the glue you used as a kid, your paste-eating habits might be a little more understandable.
