With the 4th of July holiday weekend approaching, I find myself wanting to share the most colorful and festive recipes with you. I began the week with the most delicious Monster Cookie Ice Cream Sandwiches that were bursting with colorful M&M’s and now I have perhaps the most colorful creation I have yet to make: M&M Rainbow Cake!
Every person who saw this cake immediately asked, “how did you make that?” So I have a full photo tutorial of how to make a rainbow cake for you. I promise it is super simple, yet the results are so bright and vibrant. I love that you can customize this technique to coordinate with whatever event you are making a cake for. I will tell you how to customize the cake a little later.
For now, let’s run through the steps of how to make a rainbow cake so that you can see how truly easy it is.
We begin with a classic butter cake recipe. I used my favorite butter cake recipe from The America’s Test Kitchen Family Baking Book, but here’s where you could make it even simpler and use any white or yellow box cake mix if you want to. Once the cake batter is well combined, you simply divide the batter evenly into as many medium-sized bowls as colors of cake you want. I divided the batter into six bowls because I wanted all of the colors of the rainbow: red, orange, yellow, green, blue and purple. (If, for example, you wanted to make a red, white and blue cake for the 4th of July, you would divide the batter into only three bowls.) When I say divide the batter “evenly”, I mean roughly evenly. I didn’t measure or weigh my bowls to be exact when dividing the batter I just eyeballed it.
Next you will mix a different color food coloring into each bowl. I like the gel food coloring because the colors are so potent and vibrant.
Now it’s time to put the colored batter into your pans. For this cake, I used two 9-inch round cake pans. Pour half of your first color (red in my case) into each pan.
Next, take your second color (orange for me) and pour half of that color batter slowly into the center of the first color in each of the two pans. The first color will slowly spread into a wider circle as you pour your second color in the middle of it.
Proceed with the remaining colors until it looks like this:
That’s it as far as the color layering goes! I told you it was easy!
Now off to the oven with the cakes to bake.
Once cooled, you frost and decorate the cake any way you like. For a tutorial about how to frost a layer cake CLICK HERE. I used Mega and regular-sized M&M’s for my decorative pattern.
Have a wonderful 4th of July weekend!
