Ingredients Method Notes

Ingredients
  

  • ½ cup unsalted butter melted
  • ¾ cup granulated sugar
  • ¼ cup brown sugar packed
  • 2 large eggs
  • 1 tsp vanilla extract
  • ½ cup unsweetened cocoa powder Dutch-process preferred
  • ½ cup all-purpose flour
  • ¼ tsp salt
  • ½ cup chocolate chunks or chips optional
  • ½ cup chopped nuts optional

Method
 

  1. Preheat the oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving some overhang for easy lifting.
  2. In a large microwave-safe bowl, melt the butter and let it cool slightly.
  3. Whisk in granulated and brown sugar until combined and glossy.
  4. Add eggs and vanilla, whisking until smooth and thickened.
  5. Sift in cocoa powder, flour, and salt directly into the bowl.
  6. Fold gently with a spatula until just combined. Do not overmix.
  7. Stir in chocolate chunks or nuts, if using.
  8. Pour the batter into the prepared pan and smooth the top.
  9. Bake for 25–30 minutes, or until a toothpick comes out with a few moist crumbs (not wet batter).
  10. Cool completely in the pan before slicing into squares for clean edges.

Notes

  • Do not overbake — this keeps the brownies moist and fudgy.
  • Use Dutch-process cocoa for a deeper chocolate flavor.
  • For clean cuts, chill the brownies for 15–20 minutes before slicing.
  • Add your favorite flavor variations: peanut butter swirls, caramel, or extra chocolate chunks.
  • Store at room temperature for 4–5 days, or freeze for up to 2 months.
