Ingredients
- 1 cup (5 ounces) plus 2 Tablespoons all-purpose flour
- 1/2 teaspoons salt
- 1/4 teaspoon baking soda
- 3 Tablespoons unsalted butter
- 1/2 cup plus 2 Tablespoons packed dark brown sugar
- 1/4 cup creamy peanut butter
- 2 teaspoons vanilla extract
- 1 large egg
- 1/2 cup bittersweet (60% cacao) chocolate chips
Preparation
Step 1
1) Preheat the oven to 375º F. Line two large baking sheets with parchment paper. Whisk the flour, salt, and baking soda together in a bowl.
2) Melt the butter in a light-colored small saucepan or skillet over medium-high heat, swirling constantly, until the butter is dark golden brown and has a nutty aroma, 3 to 5 minutes.
3) Place the brown sugar and vanilla into a large mixing bowl. Add the browned butter and peanut butter and whisk until incorporated. Whisk in the egg until the mixture is smooth with no lumps, about 30 seconds. Let the mixture stand for 3 minutes, then whisk vigorously for 30 seconds. Repeat this process of resting and whisking twice more until the mixture is thick, smooth, and shiny. Stir in the flour mixture and 6 Tablespoons of the chips until combined.
