Ingredients
For the brownies:
  • 1/3 cup unsweetened cocoa powder
  • 1/2 cup oil (canola or vegetable)
  • 1/2 cup butter , softened
  • 2 cups granulated sugar
  • 4 large eggs
  • 2 teaspoons vanilla
  • 1 1/2 cups flour
  • 1 teaspoon salt
  • 3 cups mini marshmallows
For the frosting:
  • 1/2 cup melted butter
  • 1/3 cup unsweetened cocoa powder
  • 1/3 cup evaporated milk
  • 1 teaspoon vanilla
  • 3 – 3 1/2 cups powdered sugar
Instructions
  1. Preheat oven to 350 degrees F. Grease a 9×13” pan with non-stick cooking spray.
  2. In a large mixing bowl, pour oil over cocoa powder and mix. Add softened butter and mix until smooth. Add sugar and mix for 1 minute.

  3. Add eggs, one at a time, mixing after each addition. Add vanilla and mix. Add flour and salt and stir to combine.

  4. Pour batter into prepared pan. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean.

  5. Remove brownies from the oven and sprinkle the marshmallows evenly on top. Return to the oven for 2-3 minutes or until the marshmallows are puffed. Remove from oven and allow them to cool completely.
  6. Once brownies are cool, make the frosting.
For the frosting:
  1. Add melted butter, cocoa powdered, evaporated milk, vanilla, and 2 cups of powdered sugar to a mixing bowl and beat with electric beaters until smooth.

  2. Add more powdered sugar, a cup at a time, mixing well, until you reach your desired frosting consistency. I usually use about 3 1/4 cups powdered sugar.

  3. Spread frosting over the cooled brownies and cut into squares. I’ve found a plastic knife works best to cut them, or if you make them 1 day in advance they are much easier to cut.
