Ingredients

Scale

*For the brownies:*

  • 1 cup melted salted butter
  • 2 tbsp vegetable oil
  • 1 ¼ cup granulated sugar
  • 1 cup light brown sugar
  • 4 eggs
  • 2 tsp vanilla extract
  • ½ tsp salt
  • 1 cup all-purpose flour
  • 1 cup cocoa powder (Ghirardelli brand recommended)
  • ¾ cup bittersweet chocolate chips (Ghirardelli brand recommended; or use semi-sweet if you prefer!)
  • ½ cup M&Ms

*For the frosting:*

  • ½ cup melted salted butter
  • ½ cup cocoa powder
  • 2 cups powdered sugar
  • 1 tsp vanilla extract
  • 23 tbsp milk
  • 1 cup mini M&Ms (you can use regular M&Ms too!)


Instructions

*For the brownies:*

  1. Preheat the oven to 350°F and grease and line an 8×12 or 9×11 baking pan with parchment paper.
  2. In a large bowl, mix the melted butter, oil, granulated and brown sugar. Whisk until combined.
  3. Add vanilla and eggs, beating for 30 seconds until the batter lightens.
  4. Sift in flour, cocoa powder, and salt. Mix lightly until just combined.
  5. Gently fold in the chocolate chips and M&Ms.
  6. Pour the batter into the prepared pan and spread evenly.
  7. Bake for 25 – 30 minutes or until the center no longer jiggles. For fudgy brownies, avoid overbaking. If you prefer cakey brownies, bake for 5-8 minutes longer.
  8. Remove from the oven and let cool completely before frosting.

*For the frosting:*

  1. In a large bowl, combine melted butter, cocoa powder, and vanilla extract. Beat together until smooth.
  2. Slowly sift in the powdered sugar, beating on medium speed until the frosting is smooth and creamy (about 1 minute).
  3. Add 1 tablespoon of milk at a time until you reach the desired consistency.
  4. Spread the frosting immediately on the cooled brownies and sprinkle on the remaining M&Ms.
  5. Enjoy your delicious treat!
