How to Make a Rainbow Cake
I have made several rainbow cakes and they are so much fun! It takes a little extra time to dye your batter and bake each layer separately, but it is really quite simple.
1. Separate your batter equally into 5 or 6 separate bowls. Tip: I use boxed cake mix for kids parties and large cakes and get just as many compliments as my scratch cakes. It is much easier and predictable when you are making a lot of cake and most people cannot tell the difference.
2. Dye each bowl of batter a separate color. Tip: I use AmeriColor Soft Gel Paste. Purple is tough – if you don’t use enough dye, then the cake will look gray which is quite unappetizing.
3. Bake each color of batter separately in a 6 inch or 8 inch cake pan. Tip: Keep an eye on it as it will bake faster since each layer will be very thin.
4. Once cooled, stack each cake with frosting in between each layer.
5. Frost cake with enough layers that you cannot see the cake color.
6. Slice dramatically!
You can make a tie dye looking cake by combining different colored batters into one. Tip: Bake the combined batters immediately so the colors do not mix too much.
