Preheat oven to 350°F and line a muffin tin with cupcake liners.

In a large bowl, mix together cake mix, eggs, oil, water, orange juice and zest until just combined. Scoop mixture into prepared muffin tin and bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean. Let cool completely.

In a small bowl, whisk frosting with food coloring until the desired color is achieved. Frost cooled cupcakes and decorate with cocoa rice cereal and mini chocolate eggs.
