Rainbow cupcakes are the perfect addition to a kid’s birthday party, or a fun summer treat! You’ll have so much fun mixing colors and decorating the tops with festive sprinkles!
You’ll have so much fun mixing colors. Do you want purple cupcakes? Pink? Neon yellow? They’re all possible!
The batter will cook into each other to give you rainbow cupcakes. Now, how much fun is that!
Aside from perfecting the batter colors, this recipe is SO EASY! Don’t bother buying a $4 tub of icing either; making it from scratch is cheap, easy and so much more delicious.
- Preheat your oven to 325 degrees and follow the instructions on the package of white cake mix. For mine, I needed three eggs, oil and water.
- Mix your ingredients together with a whisk to remove any clumps.
- Once batter is smooth, divide it among however many colors you want — I picked four (note: the cake will bake to a lighter color than the batter).
- Divide the batter into a cupcake pan lined with cupcake holders (tip: use a separate spoon for each bowl of batter) – going down the rows of the pan I put a tablespoon of blue batter in each cup, then repeated it with lime, rose and orange. Caution: Only fill cups 3/4 of the way! They will overflow if you don't.
- Place the cupcakes in the center of the oven for about 16-19 minutes until a toothpick comes out clean.
- Let cupcakes cool for 10-15 minutes. If you’re anxious like me, put them in the fridge for 5 minutes to speed it up! Once cooled, ice your cupcakes. For mine, I crafted a Vanilla-Cinnamon Icing recipe from scratch (recipe here). Then decorate with sprinkles or nonpareils.
- Tip: If you’re traveling with these cupcakes like I did (learn how to protect the icing while transporting here), make them the night before and leave them in the fridge overnight. This will ensure that the icing is set.
