Ingredients
12
tablespoons/170 grams butter, salted or unsalted, plus more for greasing
1
cup/220 grams packed brown sugar, light or dark
2
large eggs
1 ½
teaspoon pure vanilla extract
1
cup/128 grams all-purpose flour
½
teaspoon baking powder
¼
teaspoon baking soda
¾
teaspoon kosher salt
1 ½
cups/255 grams bittersweet chocolate chunks or chips
Preparation
- Heat oven to 350 degrees. Grease and line a 9-inch square baking pan with parchment paper, leaving a 2-inch overhang on two sides.
- In a medium saucepan combine the butter and sugar, and heat over medium until the butter is melted. Remove from the heat, and whisk vigorously until well combined.
- Let mixture cool for about 10 minutes, then whisk in the eggs, one at a time. Whisk in the vanilla.
- Add the flour, baking powder, baking soda and salt, and stir to combine. (You might still have some flecks of flour. That’s OK.) Stir in 1 1/4 cup of the chocolate. Transfer to the prepared pan and smooth the top. Sprinkle with the remaining chocolate.
- Bake until the very top looks just set, and a toothpick inserted into the center comes out with moist crumbs attached, 18 to 20 minutes. Do not overbake.
- Transfer to a rack to cool completely, about 45 minutes. Lift out using the paper, and transfer to a cutting board. Cut into 16 pieces.
