At the weekend I decided I needed cake and after seeing a couple of rainbow cakes around I decided to give one ago.
I didn't have time to pop to the cake shop to get some proper gel colours so had to use the silver spoon ones I had already.
The colours didn't come out too wishy washy and it looks really good, covered in a vanilla buttercream against the colours looks so effective.
Searching on the internet the ones with proper gel food colours from the cakes shops look really good so I might get some next time I am in.
I really enjoyed making this and even got to use the new icing turntable I found in a charity shop, it works so well and makes icing super easy.
