Ingredients

  • 1 box Brownie Mix (Duncan Hines) Dark Chocolate Fudge
  • 1 tbsp Cocoa Powder Dutch Processed
  • 1/3 cup Milk 83 grams
  • 1 Egg
  • 1/4 cup Unsalted Butter (melted) 57 grams
  • 1/4 cup Vegetable Oil 60 grams
  • 2 tsp Vanilla Extract 8 grams
  • 1/2 tsp Salt
  • 1/4 cup M&Ms
  • 1/4 cup Chocolate Chips Milk, Dark, or Semi-Sweet

Instructions

  • Preheat oven to 350°F. Prepare 8x8 square pan with baking spray or a homemade pan release. You can also use parchment paper at the bottom for extra insurance and easy removal.
  • In a microwave-safe bowl, microwave the butter at 15-30 second intervals until completely melted. Set aside until ready to incorporate into your recipe.
  • Combine brownie mix, cocoa powder, and salt in a medium-size bowl and whisk together.
  • Now, add milk, egg, melted butter, vegetable oil, and vanilla extract.
  • Mix ingredients together on low with an electric hand mixer, or by hand with a silicone spatula. Make sure all ingredients are incorporating and not stuck on the bottom.
  • Add m&ms and chocolate chips. Gently fold in until evenly distributed.
  • Pour brownie batter into prepared square pan.
  • Top with extra m&ms and chocolate chips if you'd like.
  • Bake for 35-37 min. Use a toothpick or knife and insert into the center – if it comes out clean or with a few moist crumbs, it’s good to go.
  • Let brownies cool in pan for 30-45 minutes, and transfer to a wire cooling rack to finish cooling.
