Rainbow Birthday Cake

Isabella chose a 'Rainbow' theme for her fifth birthday. After last year's Ginger Bread House fiasco where stress levels were high to say the least I was determined to make this year's cake a lot easier.
I found lots of examples of cakes with separate layers to form rainbows which all looked reasonably easy but my concern was the time involved in baking each layer. I found a couple of recipes for this cake and gave it a try several weeks in advance.
My trial cake seemed like it was going to be a bit of a disaster but turned out really well - a good sign for the 'real thing'.
The key to this cake it using a cake recipe and mixture that is pretty thick - I chose a Madeira cake for this reason and using A LOT of food colouring.

I wanted to keep the decorating quite simple to get the 'wow' factor when it was cut open. The white icing and white chocolate fingers were easy to put on.
I used a 'Butter Cream' icing (below) which was easy to work with and eventually set a bit hard.
The '5' was just cut out of paper, placed on top of the cake, then sprinkles added.
I did the top decoration before I did the white chocolate fingers so that I could keep the sides 'clean'.


Rainbow Cake
Make the cake mixture according to the recipe.  (I used about a 30cm tin and doubled the recipe. There was some mixture left over)
Take about 1/2 the mixture and use red colouring to colour. Create a red layer around the outside of the cake tin.
Next take smaller amount of mixture and colour orange and create the next layer.
Continue through the rainbow colours until you get tot he middle where you use a very small amount of purple coloured mixture.
If you have a lot of mixture left over you can colour it according to the colour you are short on and add mixture in. The cake is very forgiving!
