Share a little about the materials, processes, and techniques used to create this cake The cake is a 3-tiered vanilla rainbow cake covered in vanilla buttercream and buttercream fondant. The dog and his accessories are made from gumpaste and the dog house is a carved rice krispie treat covered in fondant. The grass is piped on buttercream. What advice would you give someone starting this project? This cake was challenging only because of the temperature and the humidity of the house I was creating it in (not my own but a rented lake house on the water during a heat wave!). I think anyone can make this with enough time and patience!
