Ingredients
Scale
- 1 cup unsalted butter (for browning)
- 1 cup granulated sugar
- 1 cup packed brown sugar
- 4 large eggs
- 1 tablespoon vanilla extract
- 1 cup all-purpose flour
- 1 cup unsweetened cocoa powder
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 2 tablespoons espresso powder (or finely ground coffee)
- 1 cup chocolate chips (optional)
Instructions
- Start by browning the butter. In a medium saucepan over medium heat, melt the butter until it becomes golden brown and has a nutty aroma. This usually takes about 5-7 minutes.
- Once browned, remove it from heat and let it cool slightly.
- In a large mixing bowl, combine the granulated sugar, brown sugar, and brown butter. Mix until well combined.
- Add in the eggs, one at a time, mixing well after each addition. Then stir in the vanilla extract.
- In another bowl, whisk together the flour, cocoa powder, baking powder, salt, and espresso powder.
- Gradually add the dry ingredients to the wet mixture, stirring until just combined.
- If using, fold in the chocolate chips.
- Pour the batter into a greased 9×13 inch baking pan and smooth the top.
- Bake at 350°F (175°C) for 25-30 minutes. A toothpick should come out with a few moist crumbs.
- Let cool completely before cutting into squares.
