Description

These fudgy m&m brownies are the sweetest way to bring color to your dessert table! This brownie recipe has the perfect balance of fudgy and chewy, packed with colorful m&m’s and melty chocolate chips throughout. 


Ingredients

Units Scale
  • 1 Box Brownie Mix
  • 1/2 cup Melted Butter (salted)
  • 1 Egg
  • 1 Egg Yolk
  • 1/4 cup Water
  • 1/2 cup Mini M&Ms (see instructions)
  • 1/2 cup Chocolate Chips

Instructions

  1. Preheat & Prep: Start by preheating the oven to 325°F. Prepare a parchment lined 8×8 inch square pan with baking spray or a homemade pan release. Let the parchment hang over the edges—instant handles!
  2. Melt Butter: In a microwave-safe bowl, microwave the butter at 15-30 second intervals until completely melted. Set aside
  3. Combine the Ingredients: In a large mixing bowl, add the brownie mix, egg, egg yolk, melted butter, and water. Stir until the batter is almost combined—don’t over-mix.

  4. Chocolate Chips: Add the mini m&m’s (reserve 1 tablespoon for topping) and chocolate chips to the brownie batter and gently fold them in with a spatula until evenly distributed.

  5. Spread Evenly: Spread brownie batter into 8×8 prepared baking dish, until evenly spread. 

  6. Bake: Bake for 40 minutes.

  7. Top with Mini M&Ms: Pull brownie out of the oven, sprinkle with reserved mini m&m’s.
  8. Finish Baking: Bake for another 5-10 minutes or until a toothpick inserted into the center comes out mostly clean with just a few moist crumbs. We don’t want a completely clean toothpick, we want these fudgy! 
  9. Cool Down: Don’t skip the cooling time! These brownies finish setting as they cool. For clean slices and the best fudgy texture, let them cool fully (or even chill briefly) before cutting & enjoying. 

Notes

Brownie Mix: My favorite brownie mix is Duncan Hines-Dark Chocolate Fudge (18.2 oz).
