Ingredients

FOR THE BROWNIES

  • 4 tbsp 1/2 stick unsalted butter, melted, plus more for greasing the dish
  • 1/2 cup Dutch-processed cocoa powder
  • 2 oz unsweetened chocolate coarsely chopped
  • 2 1/4 cups sugar
  • 1/2 cup plus 2 tbsp vegetable oil
  • 2 large eggs
  • 2 large egg yolks
  • 1 tsp vanilla extract
  • 1 3/4 cups all-purpose flour
  • 1 tsp Kosher salt
  • 2 8-oz packages Heath toffee bits (about 3 cups)
  • 1 cup semisweet chocolate chips

FOR THE FUDGE ICING

  • 6 tbsp unsalted butter 3/4 stick
  • 1 1/2 oz unsweetened chocolate coarsely chopped
  • 1 oz bittersweet chocolate coarsely chopped
  • 1/4 cup sour cream
  • 1/2 cup plus 1/3 cup confectioners sugar

Instructions

MAKE THE BROWNIES

  • Heat oven to 350 F and butter a 9"x13" baking dish.
  • In a bowl, whisk the cocoa powder with 1/2 cup plus 2 tablespoons boiling water.
  • Melt the chocolate and butter in a double boiler, or in a metal bowl set over a saucepan of simmering water.
  • Whisk in the cocoa mixture.
  • In a large bowl, whisk together the sugar, oil, eggs, egg yolks, and vanilla.
  • Whisk in the chocolate mixture. Sift the flour and salt into the batter, and stir to combine.
  • Stir in 2 cups of the toffee chips and the chocolate chips (1 cup).
  • Use a rubber spatula to transfer the batter to the prepared baking dish.
  • Bake until a tester inserted in the middle of the pan comes out clean, about 40 minutes.
  • Allow the brownies to cool completely on a wire rack before icing.

MAKE THE FUDGE ICING

  • Melt the butter and chocolate in a double boiler, or in a metal bowl set over a pan of gently simmering water.
  • Combine the sour cream and sugar in a mixing bowl.
  • Add the warm, melted chocolate and whisk until all ingredients are combined and the icing is thick and glossy.
  • Set the icing aside in a cool space to rest at least for 1 hour, until it becomes thick and spreadable.

FINISH THE BROWNIES!

  • Use a frosting knife to evenly ice the brownies (it will be a thin layer of icing).
  • Sprinkle the remaining toffee chips over the top.
  • When you're ready to serve, slice the brownies into 12 equal bars (they'll be nice and big).
