Ingredients

Instructions

  1. Step 1: Preheat oven to 350°F. In a microwave-safe large bowl, melt 1/2 cup unsalted butter for 45 seconds until fully melted and warm. Stir in 1 cup granulated sugar until combined.
  2. Step 2: Add 2 large eggs and 1 tsp vanilla extract to the butter-sugar mixture, whisking until smooth and slightly thickened.
  3. Step 3: Sift in 3/4 cup unsweetened cocoa powder, 3/4 cup all-purpose flour, and 1/4 tsp salt. Stir gently until just combined and no streaks remain. Fold in 1/2 cup semi-sweet chocolate chips.
  4. Step 4: Pour batter into a greased 8x8 inch pan, smoothing the top with a spatula. Bake for 25-28 minutes until a toothpick inserted in the center comes out with moist crumbs. Cool completely before cutting into 16 squares.
