Ingredients

Instructions

  1. Step 1: Preheat oven to 350°F. Line a 9x9-inch baking pan with parchment paper, leaving an overhang on the sides.
  2. Step 2: In a medium heatproof bowl, melt 1 cup unsalted butter and 8 oz semisweet chocolate chips over a double boiler or in 30-second microwave bursts, stirring until smooth.
  3. Step 3: Remove from heat and whisk in 1 1/2 cups granulated sugar until combined and glossy.
  4. Step 4: Add 3 large eggs one at a time, whisking well after each addition, then stir in 2 tsp vanilla extract.
  5. Step 5: Sift together 1 cup all-purpose flour, 3/4 cup unsweetened cocoa powder, 1 tsp espresso powder, and 1/2 tsp salt.
  6. Step 6: Fold the dry ingredients gently into the wet chocolate mixture until just combined and no flour streaks remain.
  7. Step 7: Pour the batter into the prepared pan, spreading evenly with a spatula.
  8. Step 8: Bake for 30-35 minutes, until the edges are set and a toothpick inserted near the center comes out with a few moist crumbs.
  9. Step 9: Let cool completely in the pan on a wire rack before lifting out with parchment and cutting into 16 bars.
