Equipment

  • Medium saucepan
  • Whisk
  • 8x8-inch baking pan
  • Parchment paper

Ingredients
  

  • 1/2 cup (113g) unsalted butter
  • 3/4 cup (150g) light brown sugar
  • 1/4 cup (50g) granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/3 cup (35g) unsweetened cocoa powder
  • 1/2 cup (65g) all-purpose flour
  • 1/4 teaspoon (1g) kosher salt
  • 1/2 teaspoon (2g) baking powder
  • 1/2 cup (85g) chocolate chips or chunks
  • 1 cup (170g) chopped Reese's peanut butter cups

Instructions
 

Brown the Butter:

  • Melt 1/2 cup unsalted butter (113g) in a medium saucepan over medium heat. Stir constantly until the butter foams, turns golden brown, and smells nutty. Remove from heat and let cool slightly.

Make the Batter:

  • Stir 3/4 cup dark brown sugar (150g) and 1/4 cup granulated sugar (50g) into the browned butter until smooth.
  • Add 2 large eggs (about 100g total) and 1 teaspoon vanilla extract (5ml) to the saucepan, whisking until fully incorporated.
  • Mix in 1/3 cup unsweetened cocoa powder (35g), 1/2 cup all-purpose flour (65g), 1/4 teaspoon kosher salt (1g), and 1/2 teaspoon baking powder (2g) until just combined. Be careful not to overmix.
  • Gently fold in 1/2 cup chocolate chips or chunks (85g) and 1 cup chopped Reese's peanut butter cups (170g).

Bake:

  • Pour the batter into a parchment-lined 8x8-inch baking pan and spread evenly. Bake at 350°F (175°C) for 28–32 minutes, or until a toothpick inserted into the center comes out with moist crumbs.

Cool and Serve:

  • Let the brownies cool completely before slicing. Enjoy!

Notes

  • Brown Butter Like a Pro: Stir constantly over low heat until golden brown and nutty—it’s the key to a next-level flavor.
  • Line Your Pan: Use parchment paper or aluminum foil to easily lift the brownies out of the prepared pan.
  • Don’t Overmix: Mix the brownie batter until just combined to avoid dense brownies.
  • Perfect Timing: Bake until moist crumbs cling to a toothpick for that gooey center everyone loves.
