Doctor Who Tardis Birthday Cake

We are huge Doctor Who fans in this house. So when my oldest had his last birthday I was not surprised when he requested a Tardis birthday cake. It was fun and easy to create this cake.

I baked a cake mix in a 9x13 glass pan and covered it in blue frosting. I didn't plan ahead to make sure I had the right shade of Tardis blue. So I wish it was darker, but my son didn't mind. After covering it in blue, I quikly piped some outlines of door and windows and did some writing. Nothing fancy, but lots of fun.
