Chewy Cookie Bars

Ingredients

• 1 cup melted butter, slightly cooled
• 1.25 cups packed brown sugar
• 1/2 cup granulated sugar
• 2 eggs plus 1 yolk
• 1 tbsp vanilla
• 2.5 cups all-purpose flour
• 1 tsp baking soda
• 1 tsp kosher salt
• 2 cups semisweet chocolate chunks
• Flaky salt for the top

Instructions

1. 1

   Whisk the melted butter with both sugars until glossy, then beat in the eggs, extra yolk, and vanilla for a full minute.

2. 2

   Fold in the flour, baking soda, and salt just until no dry streaks remain, then stir through the chocolate chunks.

3. 3

   Press the thick dough evenly into a parchment-lined nine-by-thirteen pan, pushing it right into the corners.

4. 4

   Bake at 350F for twenty-two to twenty-six minutes, pulling the pan while the center still looks slightly underdone.

5. 5

   Sprinkle flaky salt over the hot surface and let the bars cool completely in the pan before cutting into squares.
