I've got some very strong feelings about this one. I am passionately in love with rainbow cake. Passionately, I tell you. I believe that every home should have a rainbow cake at least once a year. It should be a rule.
I also believe that the reason I feel so strongly about this, is that you can not mess this cake up. Trust me, I've tried. You can have too few pans, skimpy batter, food coloring issues, you name it, but it comes out alright in the end and it's so forgiving since you don't have to frost the outsides and make it perfect. The perfection of this cake is it's wonky imperfection. People, I can't tell you how freeing that is.
Henceforth, I shall find an excuse to bake this once a year.
basic tips for how I do this, and I hope it helps you bake a rainbow cake too!
*I have 4 eight inch pans but someday I need to grab two more. I begin by taking one, and setting it on a stack of 6 pieces of parchment paper. I trace a circle around the pan and then I cut all six out at once so I can line all my pans with parchment. I do this because the cake is very thin and this helps. Once those are cut I line up my four pans, spray them heavily with Pam cooking spray, lay the parchment circles in the bottom and spray that. I flour all my pans lightly. (I use cup for cup GF flour but any kind would work.)
*Next I take my batter and divide it evenly among all six bowls. There won't be much batter in them.
*I use red, yellow, green, blue and purple food colorings and mix orange from the food coloring box guide. I mix each bowl until the colors are bright and vibrant. Make them darker than you think they need to be and you'll be fine.
*Gently begin spreading your batter. Because it's a small amount you will need to go slow, take your time and work it around until it's edge to edge. I always have a moment of panic because it never looks like there will be enough batter to cover the whole pan! (I use a spatula to get every single scrap of batter out of the bowl.) Once its all spread, I tap the cake pan on the counter and work air bubbles out and then I put all four pans into the oven at once (reserving the final two colors until two more pans are free.) I bake them for about 13-15 min- until a knife in the center comes out clean. I let them sit 10 minutes and then flip them onto a piece of parchment. (I quickly wash and prepare two more pans and get the final two cake colors into the oven.)
*Once all the cake layers are cool, I mix up the following frosting recipe and you will use the entire batch. If you want to be precise you can always divide it up into six equal portions but I just eyeball it and make a nice frosting layer between each layer, about a half inch thick. This whole process is actually very quick and easy and suddenly you've got a gorgeous cake with very little effort. I like that.
Fluffy Cake Frosting:
*Beat 4 1/2 sticks room-temperature butter and 1 1/2 cups powdered sugar until pale and fluffy. Gradually add an additional 5 1/4 cups powdered sugar. Add 1 1/2 tbsp milk and 1 tsp real vanilla extract. Beat until pale and fluffy.
here for the rainbow tissue garland and the chalk garland came from my buddy Jen.
Ashley sent me a party box and if you also need a party box, she is your girl. She sent me rainbow colored stripey straws, (which we all know I'm totally addicted to) chevron gift bags (above, that we filled with starburst candies and a pretty polishes for the slumber party girls) wood spoons, mason jar daisy cut straw lids (for drinking shirley temples of course) and the gorgeous huge sprinkles you see on the top of the cake which happen to be my favorites. Ashely is such a sweetheart and owns my new favorite party supply store. She has a ton more cute party items in her shop which you should definitely go check out and she is soon to be expanding and adding a bunch of really fun NEW party items!! I can't wait to see what she stocks!
slumber party movie, and I reserved some in goody bags to send the girls home with so they can remember the fun night. We laid popcorn out on cookies sheets and then used colored candy melts to drizzle over the top along with some funfetti sprinkles. You know, for a bit of extra fun.
