For my granddaughter’s 5th birthday
I found this tutorial really helpful for making the carriage if you are interested – although I used RKT rather than cake here – http://www.cake-talk.co.uk/blog/cinderellas-coach-cake-tutorial/
Tiers were bottom – vanilla Madeira with strawberry Swiss meringue buttercream, middle – chocolate mud cake with vanilla Swiss meringue buttercream, top – same as bottom – all covered in Belgian chocolate ganache.
