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.

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
• FOR GLAZE:
• 2 cups powdered sugar
• 2 TBSP milk
• Rainbow sprinkles

Instructions

1. Preheat your oven to 350°F. Generously grease a 9 to 10-inch Bundt (tube) pan.
2. 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. 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 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. 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.
