First thing I did was grab two pieces of paper and my two 8" round pans and traced each one on the paper. I then cut them out so I had two circles. I cut a little bit off the first circle so my cakes would fit nicely together. You can see this better in the next picture.
Next I covered the bottom layer with some homemade buttercream frosting I made and lightly frosting the top layer. It didn't need to be frosted perfectly on top because I would be adding more frosting on later.
Here's the my 2 on the cake:)
I then filled in the areas missing frosting.
I then covered the top of the cake with more frosting and used a Wilton tip #21 to make it look like grass along the race track.
