Ingredients

  • 1 cup salted butter melted
  • 1 1/3 cup semi-sweet chocolate chips
  • 1 1/3 cups 60% cocoa chocolate chips
  • 1 1/2 cups granulated sugar
  • 1/2 cup brown sugar
  • 6 large eggs
  • 1 tablespoon vanilla extract
  • 1 1/4 cup all-purpose flour
  • 1/4 cup unsweetened cocoa powder
  • 1/2 teaspoon salt
  • 3/4 cup regular M&M's®
  • 3/4 cup Peanut Butter M&M's®
  • 3/4 cup Pretzel M&M's®

Chocolate Frosting

  • 1/2 cup butter margarine will not work
  • 6 tablespoons buttermilk
  • 3 3/4 cups powdered sugar
  • 4 tablespoons cocoa
  • 1 tablespoon vanilla
  • 1 cup Mini M&M's®

Instructions

  • In a microwavable bowl, melt butter on high for 1 minute. Add in chocolate chips and heat in intervals for 30 seconds, stirring in between intervals. Repeat until completely melted, smooth and combined - about 1 1/2 - 2 minutes. Set aside.
  • Preheat oven to 350 degrees, and prepare large 17x10 baking sheet by spraying with cooking oil. Set aside. If you want to use a 9x9 pan, halve the recipe.
  • In a small mixing bowl, combine flour, cocoa powder, and salt. Set aside.
  • In a large mixing bowl, add sugar and brown sugar. Slowly mix in chocolate and butter mixture, and then the vanilla until well incorporated. Add in one egg at a time, beating in between each addition.
  • Gently stir in the flour mixture and fold in M&M's®, Peanut Butter M&M's®, and Pretzel M&M's®.
  • Pour the Millionaire Brownie batter into the prepared baking pan. Place in oven and bake for 35-38 minutes or until the brownies start to pull away from the edges of the pan, check at 30 minutes to see how they are doing. I always pull mine out at 35 minutes. Insert a toothpick in the center of the brownies; it should come out with a few moist “crumbs”. At this point, it is done.
  • Set brownies aside to completely cool.
  • Once cooled, prepare frosting.
  • In a microwave safe bowl add butter, cover and heat for 1 minute.
  • Add in buttermilk and cocoa and heat for 2 minutes stirring every 30 seconds.
  • Add in powdered sugar and heat for 1 minute, stirring every 30 seconds. Quickly stir in vanilla and pour over frosting, if frosting started to stiffen with the vanilla heat for another 30 seconds, then pour on brownies.
  • It is possible to overcook the frosting, so be sure to heat according to directions.
  • Perfect game night addition!
