These M&M Brownies might be your new favorite after you try them! They are decadent, rich, fudgy and overloaded with chocolate.

  • 1 cup (226g) unsalted butter
  • 4 ounces (113g) unsweetened baking chocolate coarsely chopped
  • 2 cups (400g) granulated sugar
  • ¼ cup (20g) unsweetened cocoa powder
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • ½ teaspoon salt
  • 1 ⅓ cups (162g) all-purpose flour
  • 2 cups M&Ms plus more for topping


  • Preheat oven to 350°F. Line a 9×13″ pan with foil and spray with nonstick cooking spray.
  • Melt butter in a saucepan over medium heat. Cook, stirring often, about 6 minutes, until it becomes brown in color. It will foam, reduce, then foam again. Once it’s done cooking the foam is a light brown and it will dissipate after you remove it from the heat. Once it starts to brown, keep stirring so it doesn’t burn. Once it gets to an amber color, turn off the flame.
  • Add baking chocolate to the butter and stir until the chocolate is melted. Stir in sugar, eggs, vanilla, salt, and cocoa and stir until combined. Stir in flour then stir in M&Ms.
  • Pour brownie batter into prepared baking pan. Sprinkle with more M&Ms. Bake for 25-35 minutes until a toothpick along the edge comes out with just a few crumbs. This results in very fudgy gooey brownies. Cool before slicing into bars.



  • You can use any M&Ms you like for these brownies – there are so many options these days you can make these brownies over and over and never use the same M&Ms twice!
  • Not an M&M fan? You can use other kinds of candy in this recipe – chopped candy bars, peanut butter cups, Reese’s Pieces, or skip the candy and load them up with more chocolate chips.
  • For the best fudgy brownies, don’t overbake them. I like to take them out of the oven once I can insert a toothpick in the edge and only a few crumbs come out with it.
  • Want clean-cut slices? Use a plastic knife to slice the brownies. Works every time.
