Step by Step 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 light 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 8×8-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!

Expert Tips and Notes

• 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.
