M&M Brownies Recipe


M&M Brownies are easy to make and guaranteed to satisfy your craving for something sweet. They are fudgy and chocolaty with your favourite M&M's in the batter. The luscious icing topped with more M&M's makes these Brownies the best ever!


1/2 cup butter

1/4 cup cocoa powder

2 eggs, room temperature

1 cup granulated sugar

3/4 cup flour

1/8 tsp. salt


1 and 1/3 cups powdered sugar

1/3 cup cocoa powder

3 tbsp. butter

4 tbsp. hot coffee or water

1 cup M&M's divided (optional add more M&M's)


  1. In a small saucepan, melt butter and coca powder over low heat, stirring the cocoa powder into the butter as it melts.
  2. In a medium mixing bowl, beat eggs until frothy.
  3. Add in granulated sugar, all-purpose flour and salt. Pour butter and cocoa mixture over top and stir just until combined.
  4. Fold in 1/4  cups M&M's into the batter.
  5. Turn into a greased 8x8 inch square baking pan.
  6. Bake in 350°F oven for 25-30 minutes. (Edges will begin to pull away from pan when they are done. These brownies taste best a little under baked).
  7. Cool on wire rack.
  8. For icing, combine powdered sugar, cocoa powder, butter and hot coffee (or water) and mix together until combined, then beat until nice and creamy.
  9. Frost brownies while warm, then top with remaining 3/4 cup of  M&M's.


  • I like to use 1/4 cup of M&M's in the batter and 3/4 cup on top but you can adjust the amounts to your taste.
  • The icing calls for hot coffee. I like to use the instant coffee granules mixed in boiling water for a stronger flavour. You can easily substitute this with water instead of the coffee.
  • Optional - add 1/2 cup chopped walnuts or pecans for additional crunch.
