Nyan Cat Cake

Hey everyone :) This is a Nyan Cat cake that I made for my partners birthday. The inside of the cake was actually easier than I had thought. I just baked 4 layers of cake and cut the layers into rings of sponge. Then I alternated the colour/ flavour as I put them together.
I used butter cream to help hold the rings together because I was short of time. But you can do it without by assembling the rings, pouring a syrup over them and then wrapping it very tightly and freezing for a bit.
Once assembled I applied a crumb-coat and then covered with the fondant.

As with all my posts I'd love to hear feedback and hear from others who enjoy cake baking and decorating or are interested by it :)
