Ingredients

The following ingredients have 9 Servings
  • 3/4 cup 1 1/2 sticks unsalted butter
  • 3 oz unsweetened baking chocolate (coarsely chopped)
  • 1 cup firmly packed light brown sugar
  • 1/2 cup granulated sugar
  • 3 eggs
  • 3/4 cup unbleached all purpose flour
  • 1/4 teaspoon salt
  • 1 teaspoon pure vanilla extract

Instruction

  • Preheat the oven to 325 F. Place cast iron skillet on stovetop burner.
  • Cut butter into 6 chunks and place in skillet with the chocolate. Cook over very low heat, stirring occasionally with a wooden spoon.
  • Because the heat is low, it can take some time, so measure out your other ingredients while it's melting, so you aren't tempted to turn up the heat!
  • When the chocolate and butter are completely melted, remove pan from the heat and add both sugars. Stir until everything is combined.
  • Add eggs, one at a time, stir well after each addition.
  • Add vanilla, stir well.
  • Add flour and salt and stir until there are no traces of flour left.
  • Use a rubber spatula around the edge of the pan to clean off the sides and get all the batter into the middle.
  • Place skillet in the oven and bake for 50 minutes. Insert a toothpick into the center to test for doneness. Toothpick should come out clean, with the possibility of a couple of crumbs. If it's still wet, put back in the oven and bake at 5 minute intervals.
  • Allow to cool on a wire rack for about 15 minutes. If you like warm brownies with ice cream and chocolate sauce (mmmmmmm!), cut a wedge now. :) Otherwise, cool brownies completely before cutting into wedges.
