Equipment

Ingredients

1 cup unsalted butter melted and then cooled for at least 5 minutes (226g)
1 cup light brown sugar firmly packed (200g)
¾ cup granulated sugar (150g)
2 large eggs + 1 large egg yolk room temperature preferred
1 ½ teaspoons vanilla extract
2 ¼ cups all-purpose flour (285g)
2 teaspoons cornstarch (cornflour in the UK)
½ teaspoon baking powder
1 teaspoon salt
2 cups semisweet chocolate chips (340g)

Instructions

Preheat oven to 350F (175C) and prepare a 9x9" (23x23cm) pan (see note) by lining with parchment paper (or lightly grease and flour).
Combine melted (cooled) butter and sugars in a large bowl, stir well.
Add eggs, egg yolk, and vanilla extract and stir until well-combined.
In a separate, medium-sized bowl, whisk together flour, cornstarch, baking powder, and salt.
Gradually stir dry ingredients into wet until completely combined. Stir in chocolate chips.
Spread batter evenly into prepared pan. Bake on 350F (175C) for 35 minutes or until edges just begin to turn golden brown.
Allow to cool before cutting and serving (don't cool too long, though -- these are amazing when served still slightly warm!)

Notes

This recipe can also be baked in a 9x13 pan for about 24-30 minutes. Note that recipe times given are for metal pans, if you use a ceramic or glass pan the cookie bars will likely take longer to bake through, so always use the toothpick test to check for doneness.

Storing

Store in an airtight container at room temperature for up to 5 days. These cookie bars may also be frozen.
