Preheat your oven to 350°F. Take a deep breath and let yourself settle into the calming warmth of your kitchen space.

Mix your brownie mix, melted butter, egg, and flour together in a large bowl/ until a thick dough forms. Splash in the tablespoon of milk if your mixture needs a little help binding.

Fold in your optional M&M's, white chocolate chips, or classic chocolate chunks. Enjoy the playful, bright textures mixing into the rich dough.

Scoop the dough into neat, uniform balls and arrange them gently across your cookie sheet. Bake at 350°F for 8 minutes strictly until the tops lose their glossy sheen.

Let your fresh bakes rest on the hot pan for 5 minutes. Transfer them to a wire rack to finish cooling, pour a cold glass of milk, and enjoy a peaceful moment.
