Sprinkles Rainbow Layer Cake

I had so much fun with this sprinkles cake and I can’t wait until everyone cuts into it to reveal the rainbow layered surprise on the inside at a birthday party celebration this afternoon. With everything I had going on Sunday (Manicure Mondays, Superbowl Slowcooker Chili, and this cake), I totally cheated and used store bought cake mix and frosting (yikes, our secret). I also thought that would be best so I can tell you exactly how much to buy and how to divide it up evenly for the rainbow layers.

Sprinkles Rainbow Layer Cake

I’ve been addicted to decorating the insides of cakes, as well as the outside, ever since I did a tie dye cake for my friend’s birthday 3 years ago. Since then I’ve colored batter for my 4th of July cupcakes, candy corn cupcakes, whoopie pies, and now this rainbow layered sprinkles cake.

I started with a box of Duncan Hines white cake mix. White cake mix (no vanilla or egg yolk) is best so that you get true color after adding the dye to each bowl of batter. A box of Duncan Hines white cake mix makes “almost” 5 cups of batter when combined with the eggs, oil, and water. Since this was an easy number to work with, I decided to make my cake 5 layers and dye each of them to match the sprinkles.

Divide the batter into 5 bowls with almost a cup of prepared batter into each bowl. Add in food coloring, in the colors of your choice, and it takes quite a bit if you are going for bright sprinkles colors as I did. Cook each layer according to the directions on the box {maybe a little less time since the layers are thin} in a separate cake pan – the batter will be thin, so try your best to spread evenly. Luckily I have 4 cake pans that were all 9 inches, so it was easy to keep rotating cake pans, 2 at a time, in and out of the oven.

Once all of your layers have cooled. Stack them on a cake plate using a thin layer of frosting between each layer. I ended up needing 2 1/2 tubs of Betty Crocker Whipped Cream Cheese frosting to finish off the layers, top, and sides. To decorate the cake {so dang easy}, go crazy with sprinkles everywhere. I picked up one large container of sprinkles at Michael’s for under $3 with about a 1/4 of sprinkles left over.

So what do you think of my sprinkles cake. Do you think rainbow layers and a sprinkles cake is something you’d try?
