I visited several websites to get ideas on how to make it. In the end I did it my own way - but it turned out pretty well. Thanks for the suggestion, Kara!
So - here's how:
- Two boxes white cake mixe (I have my favorite white box cake - this is about looks, so no need to complicate the process with homemade cake!)
- Eggs, oil and water for cake
- food coloring GEL - helpful hint picked up from blogs - gel colors are brighter than regular food coloring
- round cake pans
- Icing (lots and lots! I included my recipe below if you want to make homemade cream cheese icing)
Repeat process with next three colors.
ROY G BIV is the acronym I learned in school for the colors of the rainbow. Red, orange, yellow, green, blue, indigo, violet. I only made six layers... but the sky's the limit!!
Spread a think layer of icing between each cake. A helpful hint: spread a super thin layer over the top of each cake before adding the total amount of icing you want. This allows the icing to spread smoothly without pulling up pieces of cake.
This final product was yummy!
Cream cheese icing:
3 - 8 ounce packages of cream cheese
2 sticks of butter (1 cup of butter)
3 cups of powdered sugar
1 1/2 tsp of vanilla
You may add more powdered sugar to get your desired consistency.
