John Deere Tractor Tire Cake

I was super excited to do this cake! It was for a little boy's birthday and all she asked for was something that went with the theme of wheels. So I thought a tractor tire!
This is a 10 in. chocolate cake with chocolate buttercream icing. Starting with chocolate icing made getting the black easier. I didn't get the black icing quite as dark as I had planned to but it was starting to affect the taste.
I did cut out part of the middle of the cake to get the 3D aspect of a tire. This was a fun cake to make!
