I used to think it was 30. Then 40. Then 50. Now I'm thinking 90 or 100.
This cake is for a 40-year-old doctor (explains the ambulance running over the brown-haired doctor).
The cake is covered in buttercream and decorated with fondant (for the hills and road). The signs are decorated shortbread cookies, and the ambulance is made from rice crispies treats.
The ambulance even says AMBULANCE (backwards) on the front.
If someone bought me this cake for my birthday, I definitely wouldn't mind being over the hill.
