Before reading the following recipe I was about to believe that such cakes can’t be real and there is no way to make any cake like this. But everything turned to be not that bad and the rainbow cake DOES exist. The following cake looks mind blowing and it will be a talk of the town if you manage to make it. I can just provide you with some general guidelines since the whole process of cooking is described here.

You will need:
2 boxes white cake mix
2 cans of clear diet soda
6 gel food colouring
16 oz whipped topping
2 oz instant fat-free sugar-free pudding mix

How to cook:
Carefully add the cake mix to the soda and mix them. Divide your mix by 6 and put it into separate bowls. Add colour into each bowl with its own spoon. Take two pans, place the mixture the way it is shown on pictures and bake two parts of cakes. 

Make a frosting. Just mix the pudding mix with the whipped topping.
