So this was my very first checkerboard rainbow cake! I can see myself making more in the future š
I used a special checkerboard cake tin kit before you get too excited. Once the batter is in the pans, it looks like this:

What I’ve learnt from this experimental cake was:
- The ratio of batter for each layer’s divisions was 1:3:6
- It would have been better had I used 2 quantities of cake mix / batter (in this instance I made my own butter cake)
- The amount of buttercream frosting that I used was 3/4 of the frosting recipe. And that was enough to do the cake, and also used to make extra cake pops with all the cut-offs after leveling the cakes.
