Buzz Lightyear Birthday Cake

This cake was for my nephew Daniel's first birthday party this past Saturday (24). It is my first time building a tiered cake and I am not taking full credit since a lot of help went into this: from baking, construction, and watching my baby or the cake while I take care of Nathaniel. It was a lot of work and I had quite a few epic fails. But I still had a great time making this and I hope to take a formal class soon.

 8 inch white cake and 10 inch chocolate fudge cake covered in homemade marshmallow fondant
