The number 5!

Ian asked for a cake in the shape of the number 5 with cars on it for his 5th birthday.  He also wanted it to have some green on the cake because that is his favorite color.

This was made with one 8 in round and one 8 in square yellow cake (one batch of batter).  I cut a smaller square out of the square cake (from one corner), leaving an L-shaped cake.  I trimmed the bottom of the L to make it fit nicely alongside the round cake to form the 5. 

Filling is a half batch of buttercream and mashed strawberries.  Leftover buttercream was used to pipe the dashed stripe on the road.  Outer frosting is one batch of chocolate ganache.  Green sprinkles make the "grass" that defines the center of the 5.
