I used 2 rectangular tins sized 42cm x 30cm for this Grand Prix birthday cake. The base is a rectangular base and iced with white roll out icing.
For No. 5 I used rectangular base, cut out No.5 shape and then iced with white roll out icing. The cars are cake cut into a long trapezium shape.
Black icing – roll out and then cut into 1cm x 1cm squares. Add to cake giving a grand prix effect.
– roll by hand into shape of helmets.
– Roll out and cut in a round shape for wheels.
Grey icing – roll out and place carefully and cut on No.5 for the road effect.
White icing – rolled and cut in thin strips for road markings and stripes for cars.
– Roll out and cut in a round shape for car numbers.
