Instructions

  1. Step 1: Preheat oven to 350°F and grease a 9x13-inch baking pan. In a microwave-safe bowl, melt 1 cup unsalted butter and 8 oz bittersweet chocolate chips together, stirring every 30 seconds until smooth and glossy.
  2. Step 2: In a large bowl, whisk 2 cups granulated sugar with 4 large eggs and 2 tsp vanilla extract until pale and fluffy.
  3. Step 3: Slowly pour the melted chocolate mixture into the egg mixture, stirring continuously until combined.
  4. Step 4: Sift together 1 cup all-purpose flour, 3/4 cup unsweetened cocoa powder, and 1/2 tsp salt; fold into the wet ingredients just until no streaks remain.
  5. Step 5: Stir in 1 cup chopped pecans evenly, then pour batter into the prepared pan and bake for 30-35 minutes until a toothpick inserted near the center comes out with a few moist crumbs.
  6. Step 6: For the glaze, melt 4 oz semi-sweet chocolate chips with 1 cup powdered sugar and 3 tbsp milk in a saucepan over low heat, stirring until smooth.
  7. Step 7: Spread the warm glaze evenly over the cooled brownies and allow to set before cutting into squares.
