M&M Fudge Brownies

  • Author: Erin
  • Total Time: 50 minutes
  • Yield: Depends on size of slices (9-20)


Thick, dense, and fudgy brownies busting with triple chocolate flavor from cocoa powder, chocolate chips, and M&M candies.  These are some serious brownies.


  • 1 cup (2 sticks) unsalted butter
  • 1 cup milk chocolate chips, divided
  • 1 cup M&M candies, divided
  • 1 cup white sugar
  • 3 large eggs + 1 egg yolk
  • 1 tsp pure vanilla extract
  • 3/4 cup unsweetened cocoa powder
  • 1 cup all-purpose flour
  • 1/2 tsp salt
  • 1/2 tsp baking powder


  1. Preheat oven to 350F.  Line a 9-inch square pan with parchment paper and set aside.
  2. In a pan, melt the butter over medium-low heat.  Add the sugar and 1/2 cup of the milk chocolate chips.  Turn off the heat and stir until sugar is dissolved and the chocolate chips have melted. 
  3. Transfer mixture to a mixing bowl, using a nonstick spatula to help scrape the sides of the pan.  Let cool for about 3 minutes.
  4. Add the eggs and egg yolk, mixing after each addition.  Add the vanilla extract and stir.
  5. Add the flour, salt, baking powder, and cocoa powder.  Mix by hand or use a mixer on low until just combined, do not overmix.
  6. Fold in the remaining 1/2 cup of chocolate chips and 1/2 cup of the M&M candies.
  7. Pour batter into the prepared pan and sprinkle the remaining M&Ms on top.
  8. Bake for about 35 minutes or until the top no longer looks liquid.  Remove from oven and allow to cool completely (brownies will fall apart more readily if they are too warm when trying to slice them).
  9. Lift brownies out of the pan by grasping the edge of the parchment paper.  Slice in pieces of desired size (small is better - these are rich!) and store in airtight container at room temperature.


If you want thinner brownies, use a 9x13 pan but start checking them earlier in the bake time as they will finish faster

Don't overmix the batter, which can cause the finish brownies to be more dry and/or crumbly.

If you use semi-sweet chocolate or dark chocolate chips instead of milk chocolate, add an extra 1/3 cup of sugar to the melted butter.

Baked and sliced brownies can be frozen by wrapping individually in plastic, placing in a freezer-safe gallon bag, and freezing.  Thaw on counter in plastic wrap until they come to room temperature.
