Melt your butter (1 cup) in a small pot over medium-high heat. Once the butter is completely melted, continue to stir it for about 5 minutes, or until it starts to foam up and develops a rich amber color. Immediately remove the pot from the burner.
Let your brown butter cool in the pot for 5 minutes, and then add it to a large mixing bowl along with the brown sugar (2 cups). Whisk to combine. Once combined, whisk in the eggs (3) until they are fully incorporated.
Gently whisk in the flour (1/2 cup) and cocoa powder (1/3 cup). Once the wet and dry ingredients are homogenous, fold in the chocolate chips (3/4 cup).
Pour your brownie batter into an 8x8-inch baking dish lined with parchment paper or coated with nonstick cooking spray. Bake for 25-30 minutes, or until a toothpick comes out of the center of the pan mostly clean.
Let your brownies cool in the pan for 30 minutes. Slice and enjoy!
Notes
Preheat the Oven: Set your oven to 350°F (177ºC) so it’s ready when your batter is. Remember, every oven heats a little differently, so give it enough time to fully preheat before baking.
Prepare Your Pan: Line an 8x8-inch baking dish with parchment paper or coat it with nonstick spray for easy removal and quick cleanup. A parchment sling makes lifting the brownies out even easier!
Brown the Butter: This step is the secret to the rich, nutty flavor. Keep a close eye as it melts and foams—when it turns a deep amber and smells nutty, it’s ready. Don’t worry if browning butter is new to you; once you catch that aroma, you’ll know you’ve nailed it.
Let the Butter Cool: Be sure to cool the browned butter for a few minutes before whisking it with the sugar and eggs. This keeps the eggs from scrambling and ensures your batter mixes smoothly.
