  • 1 c butter melted and cooled
  • 2 tbsp vegetable oil
  • 1 1/4 c sugar
  • 1 c light brown sugar packed
  • 4 eggs room temperature
  • 1 tbsp vanilla extract
  • 1 c all purpose flour
  • 1 c unsweetened cocoa powder
  • 3/4 tsp salt
  • 1/2 tsp baking powder
  • 1/2 c chocolate chips
  • 1/2 c regular M&M's
  • 1/2 c mini M&M's


  • Preheat the oven to 350°F. Line a 9x13 inch baking pan with parchment paper. Set aside.
  • Add the melted butter, oil and sugars to a medium bowl. Whisk well, then add the eggs and vanilla. Whisk for 2 additional minutes.
  • Sift together the flour, cocoa, salt and baking powder into a separate bowl.
  • Pour the dry mixture into the bowl with the wet mixture. Fold the ingredients until just combined.
  • Add 1/2 c chocolate chips, 1/4 c mini M&M's and 1/4 c regular M&M's and fold into the batter until evenly distributed.
  • Pour the batter into the lined baking pan. Sprinkle the remaining M&Ms evenly over the top.
  • Bake for 25-30 minutes or until the center is cooked through and no longer jiggles.
  • Allow the brownies to cool in the pan before lifting them out and cutting.
  • Tip: Use a plastic knife to cut the brownies. It'll slice right through them.
