It was so simple to make that I wanted to share with you the secret of how it was made.
At first glance this looks like a plain birthday cake covered with buttercream and sprinkles.
But it is a disguise - for you see the inside is filled with colourful goodness.
So how did I do it? Well I didn't cut up the cake into circles and place them back together surgically, I used a Wilton Checkerboard cake pan set I bought at the Cake & Bake Show this year.
I used my trusty Margaret Fulton butter cake mix which I tripled the mixture for. I then separated the batter equally or close enough into three separate bowls and coloured each one a different colour.
Then I followed the instructions as to which section you had to pour which batter into and baked.
Once each layer was baked and cooled I could then start to decorate. I used a post-it note on each so I could remember which layer was which.
Since it was so hot and I didn't have any room in my fridge I let the cakes cool overnight and decorated the following morning.
I use a basic buttercream mix of butter, icing sugar, vanilla and a splash of milk - it's always a winner.
I spread buttercream in-between each layer to help keep it moist and taste more delicious.
I then added on the top layer and spread buttercream all around the sides and top which I covered in different coloured sprinkles.
So as you can see it's nice and simple but gives a great effect.
