Make brownie mix according to package instructions.

Place silicone egg mold on a baking sheet and spoon brownie mix into the mold, filling each cup approximately ¾ of the way full.

Bake at 350 degrees F for 20-25 minutes, or until a toothpick stuck in the center comes out clean.

When you remove the brownies from the oven, immediately press the back of a teaspoon into the brownie, creating an indent in the area where the egg yolk would be on a hard-boiled egg.

Let the brownies cool completely in the mold before gently removing.

While the brownies cool make your frosting. Combine softened butter, powdered sugar, and 1 tablespoon of water or milk in the bowl of your mixer. Mix together on medium-high speed for 3 minutes.

Add the vanilla extract and continue to mix until the frosting is light and fluffy.

Decide how many colors of frosting you want to make and divide the frosting evenly into the number of bowls needed.

Add a drop or two of food coloring to each bowl and mix.

Using a frosting bag and tip fill each brownie bite with frosting.
