Rainbow Bundt Cake (Doctored Cake Mix)- Jazz up your box of ordinary cake mix! This colorful bundt cake is perfect for your next celebration or use this method to simply give your ordinary weekday dessert a little boost. 

I'm not ashamed to admit that I love cake mixes.  In fact, I love all kinds of boxed mixes.  Brownie  mixes, pancake mixes, muffin mixes...you name it.

For this recipe, we are making a fun rainbow cake (great for St Patty's Day ☘), but, the additional ingredients we add to the cake mix can be used with any kind of cake you wish.

Ingredients Needed

• Cake mix
• Instant pudding mix
• Salt + Vanilla 
• Butter
• Eggs
• Sour cream or Plain Greek yogurt
• Milk
• Additional For Rainbow Cake 🌈
• Powdered sugar
• Food coloring

How to Make A Rainbow 🌈

• First, make your batter.
• Then, divide the plain batter equally into 6 bowls.
• Tint each bowl a different color.  When you are done, you will have 1 bowl of red, 1 bowl of green and so on.
• After generously greasing your pan, spoon the red batter onto the bottom of your pan. Go all the way around the pan,  Follow the same pattern with the remaining colors.
• Don't mix your colors/batter!  Let them stay separate.
• Bake your cake.

Recipe Notes

• If you stick with a standard size box of dry cake mix, this will work with any flavor or brand.  You can use the batter for a sheet cake, cupcakes or  a layer cake.  Use the same baking times as directed on your box of cake mix.
• Be sure to get instant pudding mix. After buying cook and serve many years ago, I always like to remind people that there is a difference.  Also, don't make the pudding.  You will just use the dry mix.

💡 Tips for Getting Your Cake Out of the Pan 

• Generously grease your bundt pan.  If you have it, use a cooking spray with flour in it.  See recipe card for product suggestion/purchase.
• Give your cake a chance to cool for 8-10 minutes, then, run a sharp knife along the edges and center of the pan.
• Invert the cake onto a plate or platter that is larger than the cake and give it a chance to fall naturally.  If it's not cooperating, give the bottom of the pan a few good taps.
• If your cake breaks a bit, no worries! You can always cover it up with the glaze. 

Rainbow Bundt Cake (Doctored Cake Mix)

By Erin

Prep: 45 mins Cook: 45 mins Yield: 8-10 slices

Ingredients

• 1 standard size box white cake mix
• 3.4 oz box dry instant vanilla pudding mix
• Dash of salt
• 4 eggs
• 1/2 cup butter, melted and cooled
• 1 cup sour cream (or plain Greek yogurt)
• 1/2 cup milk
• 1 tsp vanilla
• Food coloring: red, orange, yellow, green, blue, and purple
• 2 cups powdered sugar
• 2 TBSP milk
• Rainbow sprinkles

Instructions

1. Prep the Oven & Pan: Preheat your oven to 350°F. Generously grease a 9 to 10-inch Bundt (tube) pan.
2. Mix the Batter: In a mixing bowl, beat together the dry cake mix, dry pudding mix, salt, melted butter, sour cream, milk, and vanilla until well combined. Add the eggs one at a time, beating to incorporate after each addition.
3. Color the Layers: Divide the batter evenly into 6 separate bowls. Tint each bowl with 1 to 2 drops of food coloring and mix well until you have one bowl of each color: red, orange, yellow, green, blue, and purple.
4. Layer the Pan: Starting with the red batter, spoon it into the bottom of the prepared pan, making sure to go around in a complete circle. Repeat the layering process in order with the orange, yellow, green, blue, and purple batter. Do not mix the batters together!
5. Bake & Cool: Bake for 40 to 45 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool in the pan for 5 to 10 minutes, then invert it onto a large platter or plate. Allow it to cool completely before glazing.
6. Glaze & Decorate: Whisk together the powdered sugar and 2 tablespoons of milk until completely smooth. Spoon the glaze over the cooled cake and top with rainbow sprinkles immediately before the glaze sets.
