This easy RAINBOW CAKE is delicious, fun and full of color! If you are looking for a festive Rainbow Birthday Cake that is easy to make, this recipe is perfect!
This recipe comes from my newest cookbook, and is one of two color filled cake recipes. Of the two, this is the “quick and easy rainbow cake”, compared to the other, more time consuming cake.
Quite a bit more time consuming as you might be able to tell from this pic!
RAINBOW CAKE RECIPE
To keep this delicious rainbow bundt cake quick and easy, this recipe starts with a cake mix, that gets doctored.
Don’t let the cake mix fool you though, multiple people have told me it’s one of the best cakes they’ve ever made!
It’s so good, we put it on the cover of the book! As you can see, we did a pastel version on the cover.
One of the great things about this cake is that you can use whatever colors you like. While this cake is made in a rainbow style, you can actually use any colors, in any combo that you like.
If you make this cake without the food coloring, just as a vanilla cake, it’s still going to taste amazing.
I know not everyone wants to use food colors, and I totally appreciate that, which is why it’s important to me that you know you have that option.
This is just one of the 50 delicious recipes you’ll find in my book, The My Little Pony Baking Book. From cookies to pies, muffins to cakes, granola to French toast, brownies to biscuits, this book has so many GREAT recipes!
While created for My Little Pony fans, I can’t stress enough that the book is full of recipes everyone will love. You don’t have to be a pony fan to love these recipes!

This makes a great Rainbow Birthday Cake!
- Bundt Cake Pan
- 1 standard size white or vanilla cake mix
- 1 3.4oz package white chocolate or vanilla instant pudding
- 1 cup sour cream
- 1 cup vegetable oil
- 4 large eggs
- 1/2 cup warm water
- Food coloring as desired
- 2 cups powdered sugar
- 2 tbsp milk
- 1 tsp vanilla extract
- Preheat oven to 350 degrees F. Combine all ingredients, except for food coloring, in a large bowl and mix with an electric mixer until well combined.
- Divide cake batter evenly between six bowls. For each bowl add 1-2 drops of food coloring and mix. If more color is desired, add additional drops of food coloring until desired color is reached. Repeat with each bowl.
- Generously spray a standard sized Bundt cake pan with non-stick cooking spray. Starting with the red batter, spoon cake batter into bottom of Bundt pan. The cake batter should go around the bottom of the pan in a complete circle.
- Carefully spoon the orange cake batter into pan, placing it directly on the red cake batter, once again making sure it goes completely around the red cake batter. Try not to mix the different colored cake batters, simply spoon one on top of the other. Repeat with remaining colors in the following order: yellow, green, blue, purple.
- Place in oven and bake for 50-55 minutes or until toothpick inserted into cake comes out clean. Remove from oven and allow to cool in pan, on a wire rack, for approximately 10-15 minutes. Tap the pan firmly a few times on the countertop, gently shaking it to help loosen the cake. Carefully invert the pan onto a cake plate and lift the pan off of the cake. Allow the cake to cool completely prior to adding glaze.
- Place powdered sugar and milk into a bowl and stir well to combine. Add vanilla and stir to combine. Glaze should be thin enough to spoon over cake, but not runny. If glaze is to thick, add additional milk, 1 teaspoon at a time, until a spoonable consistency is reached.
- Spoon glaze over the top of cake. If desired, garnish with rainbow sprinkles.

Received all compliments on this cake . Did this for my daughters 14th birthday and all 14 middle schoolers loved it. My husband who doesn’t love cake but mostly icing went back for seconds and said that icing is perfect not overwhelming. Plus the cake was VERY moist.
I put each color batter in a plastic bag and snipped the corner and piped it in to make sure it was accurate. I might buy and extra batter mix next time just to make sure each layer covered the previous but it still looked amazing .
Hi, what size is a standard cake mix?
Christi Johnstone says
Any cake mix on your grocery store shelves that makes a 9×13 or 8×8/9×9 layer cake will work. So basically almost all the cake mixes from brands like Pillsbury, Duncan Hines, Betty Crocker…
