She asked for a chocolate cake with a track on it. Knowing that it was only her family that would be with her, I did an 8 inch cake. Her daughter goes to U-32 so I incorporated their school colors blue and white into the decorations.
I hadn't heard about Spackle for a cake, but apparently all you need to do is mix extra cake with buttercream and it'll work just like Spackle. It fills in any gaps that result from putting two layers together. Once it's set, regular butter cream can be put over it to give a white finish.
I tried a different technique to write on the banner but next time I'll go with the melted chocolate in a bag. The girl thought the cake was really cool. It's hearing that type of feedback that keeps me going!
