These M&M Brownies are decadent fudge brownies exploding with colorful candy crunch and melty chocolate! They’re rich and ultra fudgy, and easy to make from scratch.


  • 4 ounces dark chocolate, melted (see notes)
  • ½ cup (113g) unsalted butter, melted
  • 1 cup (190g) granulated sugar
  • 2 large eggs
  • 1 large egg yolk
  • 1 tablespoon (15ml) pure vanilla extract
  • ½ cup (70g) all-purpose flour
  • ½ cup (55g) Rodelle cocoa powder, sifted (see notes)
  • ¾ teaspoon salt
  • ½ teaspoon baking powder
  • ½ cup (112g) mini semi-sweet chocolate chips
  • ½¾ cup (100-125g) mini M&Ms


  1. Preheat the oven to 350°F.
  2. Roughly chop the chocolate and melt the chocolate in a microwave-safe bowl for approximately 2 minutes at 50% power. Stir every 30 seconds until completely melted and smooth. Set aside to cool.
  3. Combine the melted butter with the granulated sugar; beat together until well combined.
  4. Next, add the egg and egg yolk and beat for 60-90 seconds at a higher speed until the batter is fluffy (texture resembling a cake batter). Then add the vanilla extract and melted chocolate and beat until combined.
  5. Combine the dry ingredients in a separate bowl and stir to combine. Add the dry ingredients to the batter and mix just until combined. Fold in the chocolate chips and M&Ms with a spatula.
  6. Generously grease an 8-inch baking pan. Spread the batter evenly and bake at 350°F for 20-24 minutes. The toothpick should still be somewhat gooey but not wet in the center. Remove from the oven and allow to cool prior to cutting. Store in an airtight container.
