I've made a decent number of 3D cakes in the past 6 months, but most of them are fairly simple in terms of carving. Not since my batmobile cake have I carved something so complex (that was only my second time carving cake and was on a much smaller scale). I forgot how long the carving process can take! Even though I had previously prepared a scaled and elevated cake board for the cake to sit on, and a stencil to get the proportions correct, it still took me about 2.5 hours to do all the carving. Honestly I'm not sure how the time can fly by so quickly! I just kept on carving it away little by little because I had to factor in for the extra bulk that would be added by the buttercream and double layer of fondant. In the end the shape of the car isn't quite as slender as I wanted, but I'll accept it for now! Next time though...gotta be better.
The wheels were pretty time consuming, made of rice cereal treats covered in fondant with a gumpaste center. If I didn't make them the week before I'm not sure I would've been able to finish the cake on time!!
My favorite part is the LED lights. The client wasn't expecting them but I thought it was such a cool idea and really wanted it to work. Took me a while to find them but so happy I did. They are battery powered and last about 100 hours, so it was no problem to put them in the cake switched on and covered in fondant. I painted the fondant with silver petal dust and it gave such a realistic effect, definitely something I will be using in future cakes when appropriate.
