A few weeks before Scout's birthday, I had a trial run. I decided to make small, 4" cakes so that Scout had a rainbow cake to smash and the rest of the party would have the option of eating vanilla or chocolate cupcakes. The rainbow layers were actually pretty easy to put together.

To start, you need a white cake batter. You can use a box (use the egg white only recipe for better dyeing) or you can make one from scratch. Prepare the batter as directed and then divide the batter into 6 bowls (or more or less depending on how many colors you are using).
Use gel food coloring to dye the batter to your desired colors. I used this food coloring by AmeriColors and purchased at Hobby Lobby. But the Wilton colors would also work well. Traditional grocery store food coloring won't give you the intense colors like the gel colors.
Now your batter looks pretty.
If you wanted to make a traditional 8" or 9" pan, you could just pour each color into its own pan (you may have to bake in shifts) and bake until done. Again, I used 4" cake pans that I purchased in packs of 3 at Hobby Lobby. I splurged for an extra set so that I wouldn't be baking cakes forever.
For the 4" cakes, I put about 2-4 T of cake batter into each. I was not methodical about this and just used a regular spoon. I spread it as evenly as possible, and then put them in the oven.
The cakes baked for approximately 5-8 minutes (give or take).
|BTW I have 2 ovens and the bottom oven is a convection oven, but I don't know how to use it. Hints?|
To assemble, trim the tops (if you want) and then layer with frosting.
I was tempted to leave it just like this.
But the edges were a bit discolored from the greased pans, so I finished with the frosting.
Admittedly, it's not the world's smoothest frosting.
My mom had those rainbow dishes hidden in her basement. I'm going to steal them.
I also made some rainbow dancer toppers that I'll show you soon.
The genius of the cake is, of course, on the inside.
