Ingredients

  • 4 ounces unsweetened chocolate baking bar, chopped
  • 6 ounces butter
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 cup all-purpose flour 4 ¼ ounces
  • 1 ½ cups coarsely chopped toasted pecans

US Customary - Metric

Instructions

Prepare the brownies:

  • Preheat the oven to 350 F.
  • Microwave the chocolate and butter in a large microwave-safe bowl at HIGH 1 to 1 ½ minutes or until melted and smooth, stirring at 30-second intervals. Whisk in the sugar and eggs until well blended. Stir in the flour. Spread the batter into a greased 13- x 9- inch baking dish.
  • Bake at 350 F for 25 to 30 minutes or until a wooden pick inserted in center comes out with a few moist crumbs. Sprinkle the warm brownies with the toasted pecans and marshmallows.

Prepare the Chocolate Frosting:

  • Cook the butter, milk and cocoa over medium in a large saucepan, stirring constantly, 4 to 5 minutes or until the butter melts. Remove from the heat, and beat in the powdered sugar and vanilla with an electric mixer at medium speed until smooth. Pour over the pecans and marshmallows; spread to edges. Let cool 1 hour on a wire rack. Cut into squares.

Notes

How to Store

Once they’ve cooled down and been cut into squares, you can keep them fresh at room temperature for up to three days. Just make sure to place them in an airtight container or cover them snugly with plastic wrap to keep them from drying out. They last longer in the fridge for about a week. Just bring them back to room temperature before serving, or give them a quick zap in the microwave if you can't wait and want a gooey, warm treat!
