Colorful donuts on white plate

I’m all about the colors of rainbow foods, whether it’s mini Unicorn cheesecakes or rainbow pancakes. Even my white chocolate bark is covered with bright sprinkles and M&M’s.

That’s why this recipe is always such a huge hit! Not only is it easy but these delicious donuts are almost too pretty to eat. Your family will definitely be amazed and impressed when you serve these for breakfast!

Another great thing is that you can custom make these donuts to fit different themes. For example, if you’re having a Harry Potter party, you can make them yellow, and red. Green and yellow would be super cute for a St. Patrick’s Day dessert. You can even add these unicorn decorations for a unicorn party.

That’s why these rainbow doughnuts are always such a hit. Not only are they a kid friendly breakfast, but they make the perfect Easter and springtime sweet treat too. However you eat them, they’re super delish and you’ve got to try them. You’ll totally thank me!

I’m a little obsessed with baked donuts from cake mix because I’m all about the easy recipes. Why make things harder if you don’t have to, right? These turned out so cute that they’re almost to pretty to eat…I said almost!

Step 4. Spoon colored batter into the pan, a little color at a time.

Each one should be about 3/4 of the way full. Don’t do too much at once or you won’t get the pretty rainbow effect.

Step 5. Bake the donuts at 350 for 8-10 minutes, or until donuts feel firm and bounce back to the touch.

For the Donut Icing

Step 1. Open the frosting and toss the aluminum film. Warm frosting in the microwave to thin it slightly, about 30 seconds.

Step 2. Stir and divide icing into a separate bowl for each one of the rainbow colors. We left out green when doing the icing, but you can include it if you’d like. Dip donuts one at a time in the different colors.

Step 3. Place donuts a wire rack with a baking sheet underneath to catch any extra icing.

Step 4. Once all donuts are topped with icing, drizzle with the remaining icing, one color at a time. Let icing set for a bit, then serve and enjoy!

Everybody loves fresh donuts and these take them to a whole new level! Can we just make all our desserts rainbow themed from now on?

How Do You Store Cake Mix Donuts?

If you have extra cake donuts leftover, you can keep them in an airtight container at room temperature. You can also store them in the refrigerator to extend shelf life but I’m pretty sure they won’t last that long!

Variations and Add-ins for Rainbow Homemade Donuts

  • Toppings: If you want to take your donut decorating one step further, you can sprinkle additional toppings over your donuts. Rainbow sprinkles, fruity pebbles, or even finely chopped pecans would all taste delicious.
  • Box Mix: We used white cake so that colors would show up bright but yellow will work great as well.
  • Flavors: Using the regular mix a delicious flavor that falls between vanilla and butter flavored. You can experiment with the flavor using maple flavoring, caramel extract, almond flavoring or any of your favorite extracts. You can also use vanilla extract or other extracts to the frosting.
  • Fruit: Add some fruit to make strawberry or blueberry donuts.

Can you make donut holes with cake mix?

Yes! You’ll just need to use this donut hole mold to make them.

Can I Use Traditional Powdered Sugar Glaze

Yes! You don’t have to buy it…you can make a powdered sugar glaze with confectioners sugar. Just mix milk or heavy cream with the sugar until you get the desired consistency.
