Expert Tips

You can use gel food colors rather than mixing liquid colors to get the desired shade. Experiment with using your favorite colors.

To make a tie-dye effect, drag a toothpick through the batter and swirl. The result will be fun and colorful!

You can bake these into regular-size cupcakes instead. Fill paper-lined muffin cups with 1 teaspoon of each color batter. Bake as directed on box.
