I made this Dirt Bike Birthday Cake Design for a friend of mine, she has twin boys who love their dirt bikes. I baked square chocolate cakes (10×10) and stacked 3 together with the filling and froze them overnight. I carved it so the bikes weren’t just flat on the cake. I covered them in blue MM fondant and cut the bikes and guys out of fondant and assembled them on the cakes. I colored some butter cream frosting brown but didn’t quite mix it all together to get that dirt look and put it around the bottom of the cake.
They loved them! And it wasn’t even super hard to do.
