Don’t you just love when a recipe is easy and super impressive? If so, you’ve got to try these Rainbow Cupcakes!
I made them for a rollerskating party, but you can use them for a rainbow party, a unicorn themed party or even a mermaid themed party. Just change the colors to go with whatever theme you’ve got!
How to make rainbow cupcakes:
Start by mixing the white cake box mix according to package directions. Divide the batter evenly into separate bowls according to how many colors you would like to have in the cupcake. I used 4 colors: purple, blue, yellow and pink. Dye each bowl of batter to your desired color.(steps 1 and 2)
Line a muffin tin with cupcake liners and alternate dropping spoonfuls of each color into the liners until you run out of batter. Bake the cupcakes for the time instructed on your cake mix. Remove from the oven and let cool before frosting. Don’t forget to add some sprinkles! (steps 3 and 4)
Cut them in half to reveal the marbled cupcake inside!
