Her mom gave me a picture of a two tier cake she saw online and wanted me to make something similar, similar meaning she pretty wanted the same cake.
They were having a small family birthday party, and a two tier cake feeds way more than 30 people, so this is the small version.
The cake is covered in fondant, I bought the fondant already colored.
The signs are made with gumpaste and attached to the cake with wire.
My client gave me the cars to put on the cake and I attached them with royal icing
Full disclosure: How many desings can you really make on a cars cake? race tracks, signs, lights.
I looked for the original source of the cake picture given by my client online and didn't get a result.
If you have seen it, please let me know and I will update.
