I made this Cars birthday cake for my youngest son’s 3rd birthday. I used a white cake and buttercream frosting. I used crushed Oreos for the “road” and used the Wilton grass tip for the grass spots and the borders.
For the brown, I added cocoa to the buttercream and a little brown gel paste color. For the grass color, I also added a little cocoa and green gel paste. Then, I made the grass sprigs and borders a little darker green by adding more green gel paste.
This was my first birthday cake to make and I had a blast doing it, will definitely do it again!
