Yes, this is actually a cookies and cream cake with Heath candy bar icing. Here's the inspiration.
It's a basic cake batter, I used this one, with Oreo cookies mixed in the batter. A lot of Oreo cookies. Then, I used this icing recipe and added broken up Heath bars to part of it. That part I placed in between the cake layers. The rest of the regular icing was used on the outside of the cake.
It was delicious. Just eat it and enjoy.
