To put the picture of the car on the cake I printed off a coloring page. I then used a size 3 tip and traced the car’s details with my buttercream icing and let it crust. Once the icing on the cake had crusted too I was able to imprint the car onto the top go the cake and fill in the colors.
To ice the sides I did the petal technique. You put a decent dot of icing in a column up the side and then drag your small spatula through it. There are quite a few tutorials for this fabulous technique!
