Chocolate chequers cake

This morning the youngest child wanted to make a "big, stacked up cake" so we decided to go for a 4 layer chocolate chequers cake. Usually this is made by making one chocolate and one vanilla sponge cake but on this occasion purple was required and 4 layers! So we made 2 chocolate sponges and 2 purple ones.

Once cooled we cut a central circle out of each sponge and then cut round a bowl for a slightly larger circle then it was time to swap the central circle from each sponge with one of a different colour and then stack them up, making sure we alternated the main sponge colour, with jam or buttercream holding the layers together. Finally we coated the entire 4 layer cake in chocolate buttercream and sprinkled with decorations. 

It just looks like a large chocolate cake until you cut into it....

Now to find a tin tall enough to keep it in......
