Ingredients

Instructions

  1. Step 1: Preheat oven to 350°F (175°C). Grease a 9x9-inch baking pan and line with parchment paper. Melt 1/2 cup unsalted butter in a microwave-safe bowl, then whisk in 3/4 cup unsweetened cocoa powder until smooth.
  2. Step 2: Add 1 cup granulated sugar, 1/2 cup brown sugar, 2 large eggs, and 1 tsp vanilla extract to the cocoa mixture. Beat with a hand mixer until fully combined and smooth, about 2 minutes.
  3. Step 3: Sift together 1/2 cup all-purpose flour, 1/2 tsp baking powder, and 1/4 tsp salt into the batter, then fold in gently until no dry streaks remain. Stir in 1 cup semisweet chocolate chips. Pour batter into prepared pan and smooth the top.
  4. Step 4: Bake for 28-32 minutes until a toothpick inserted into the center comes out with moist crumbs (not wet batter). Let cool completely in pan on a wire rack before cutting into squares.
