To make the cake I followed this white chocolate sponge cake recipe but doubled the ingredients, apart from the buttercream, I made the same amount of buttercream and it was plenty to ice between each layer, the top and the sides of the cake.
Once I had made the cake mixture I split it out into three equal portions and added Sugarflair paste colours in sky blue, spring green and baby pink, to give you a rough idea of how well the paste colours hold the below photo is how the colours looked before baking.
Once the cake had cooled I stuck everything together with the buttercream and refrigerated overnight. The cake was massive, very stodgy, but very delicious. The colours were a little more washed out than I had hoped but still looked good.
While I am on the subject of Easter here are some ridiculously cute photos of Aria waiting for daddy to wake up on Easter morning.
