This car cake is a couple of sponge layers, cut to shape. Standard frosting with colouring for the icing. The background was a metal tray with butter smeared, and then poured hundreds and thousands all over and they stuck.
Look closely and you’ll notice the exhaust from the car was his candle, so was good when it was lit. BTW, you can tell I’m not a cake maker, as that was my first attempt at writing icing, didn’t know how hard it was!
