Ingredients
  

  • ½ cup unsalted butter melted
  • 1 cup granulated sugar
  • 2 eggs
  • 2 teaspoons vanilla extract
  • ½ cup unsweetened natural cocoa powder
  • ½ cup all‑purpose flour
  • ¼ teaspoon salt or to taste
  • 2 cups semi‑sweet chocolate chunks divided (1½ cups in batter + ½ cup sprinkled on top)

Instructions
 

  • Preheat oven to 350°F (≈175°C). Line an 8×8‑inch square pan with foil or parchment and grease lightly.
  • In a large microwave‑safe bowl or on stovetop, melt butter. Stir in sugar, eggs, and vanilla until smooth.
  • Add cocoa powder; whisk to combine. Sift in flour and salt (if needed) and mix until batter is uniform.
  • Stir in 1½ cups of chocolate chunks into batter.
  • Spread batter into prepared pan; smooth surface. Sprinkle remaining ½ cup chocolate chunks evenly on top, pressing lightly so they adhere.
  • Bake for 25‑30 minutes, until edges are set and top looks firm; center may still have moist crumbs.
  • Remove from oven, let cool completely in pan (≈2 hours). Use foil or parchment to lift brownies out, cut into 8 generous rectangles or squares.

Notes

  • Don’t overbake—once edges are set and top is firm, center may still be slightly soft but will firm up when cooled.
  • Use high‑quality cocoa and chocolate chunks for best flavor.
  • Let brownies cool fully before slicing to avoid crumbling.
  • Line pan with foil/parchment so you can lift brownies out easily.
  • For variation, sprinkle sea salt flakes on top just before serving for contrast.
