This is a 2 tiered vanilla and chocolate sponge cake. I don’t have a photo to show it, bit when you cut into the cake you get a checkered layered cake. This was easier to do than I thought. You just put the chocolate layer on top of the vanilla sponge layer and then cut the cake in 1 inch strips in parallel lines. Next you swap each chocolate layer with vanilla to get a checkered look.
Make 2 batches of buttercream icing, one just plain vanilla, the other flavoured with chocolate or cocoa powder, but dark melted chocolate works and tastes best.
Put a layer of butter cream between each layer / to sandwich the cake together. Then use a rose shaped nozzle to pipe vanilla and chocolate buttercream alternately around the cake.
It gives it a nice effect and is a tempting cake to look at.
