I wanted to give my best friend and her daughter a surprise birthday cake to share. I had a slight brain wave and came up with the idea of a Rainbow Surprise Birthday Cake, stacked layers with each one been a different colour. I did one yellow, orange, blue, purple, red and green.
Once cooled I stacked them up with a layer of buttercream and then stuck a large dowel stick to keep it in place, then gave the cake a buttercream crumb coating before leaving it in the fridge to set.
Once left overnight I then added another buttercream frosting all over and then threw ( and I mean threw them ) hundreds and thousands.
I didn’t tell my best friend or her daughter what I had done but just said then I needed a photo. I had a phone call to say WOW, how did you do that? They both loved it and I think it’s a hit with anyone you would want to surprise.
(Use white sponge mix as the colours will be more vibrant).

Hi How did you get the colours on the different sponges
Food coloring. Gels usually work best, but you can also use regular (cheaper) liquid food coloring. Wilson’s gel’s work best of all, but are also the most expensive.
