Preheat the oven to 325 degrees F. Line a 17x11-inch rimmed baking sheet with parchment paper or spray with non stick cooking spray.

Stir the brownie mixes, oil, eggs, and water together in a large bowl until well blended. Spread into the prepared pan.

Bake for 30 to 35 minutes, until a toothpick inserted about 2 inches from the edge of the pan comes out clean. Cool completely.

Use a 4x2-3/4-inch egg-shaped cookie cutter to cut 16 egg-shaped brownies. Or use a sharp knife to cut the brownies into egg shapes, just make sure they are bigger than your Peeps Marshmallow Bunnies.

Divide the frosting into bowls and dye with the food coloring. Frost the brownies with frosting, add a Peep then decorate the exposed frosting with sprinkles.
