My Famous Rainbow Cake

This cake is such a show stopper-I have had people approach me literally on the street and ask me if I’m the one who made the rainbow cake…seriously. I would love to make it for anyone who wanted me to, but you can seriously make it too, trust me, it’s really not that hard, I mean, if you really want me to make you one I will, but it’s really easy!
Like most of my recipes, it’s in the details that matter. Rather than reinvent the wheel, I’ll share the important details and let you decide the basics. This cake can be made from any cake recipe, or even by using a cake mix from the store. We’ll be doctoring it up to make it amazing, so the basic mix doesn’t really matter.

Start by mixing your cake batter. Next you’ll need to separate the mix into six parts. The best way to do this and keep it even is to have six bowls, split the mix in half, then split those in half, etc., until you have six equal parts in bowls. Add professional cake coloring to each bowl-red, orange, yellow, green, blue, purple. A little bit goes a long way, especially the yellow-don’t use too much or your yellow will look like orange. I used about 1/4 tsp for each color, slightly less for yellow. Mix color in well, bake each layer. It’s o.k. if you only have 2- 9 inch pans, just wait until the cake is cooled, wash the pan and use it again until all of your colors are really. (don’t use pans smaller than 9 inch, your cake will be too tall and fall apart!) They should all be cooled before putting the cake together. I used my basic cream cheese frosting, but you could use whatever you want.


3 – 8 oz. packages of cream cheese
1 pint of heavy whipping cream
1 cup of powdered sugar
1 T. real Vanilla (I use Penzeys)


Here’s a photo of the tools you’ll need to make this cake.  The cake coloring, icing bag and tip can be purchased at Michael’s:


When I get a chance, I’ll post a video of how to pipe those roses!  Not many people know this, but my first job when I was 16 years old was working in a McGlynn’s bakery in St. Paul. I watched the cake decorator make cakes and asked her if I could help.  I quickly caught on and in no time at all, I was even doing specialty orders for people who wanted something unique like a cake with a photo of something (sort of like a painting with frosting!)  It was really fun!
