Preheat your oven to 350°F (175°C).

In a large mixing bowl, follow the package instructions for your brownie mix, adding the required water, oil, and eggs. Stir until smooth.

Generously spray your egg-shaped silicone molds with nonstick cooking spray.

Using a 2-tablespoon portion scoop, evenly fill each cavity in the silicone molds with the brownie batter.

Place the filled molds in the oven and bake for 24-26 minutes. Check for doneness with a toothpick.

Once baked, gently press a teaspoon into the center of each brownie to create a divot.

Allow the brownies to cool completely in their molds on a wire rack.

Once cooled, gently pull back the sides of the silicone molds to release the brownies.

In a mixing bowl, beat the softened cream cheese and marshmallow cream together until smooth.

Transfer the creamy filling into a piping bag and carefully pipe it into the center of each brownie.

If desired, sprinkle festive colors over the filled brownies. Refrigerate for at least 30 minutes.

Once chilled, serve your Deviled Brownies and enjoy!
