Ingredients

Ingredients

  • 1 cup unsalted butter melted or browned (I browned my butter)
  • ¾ cup light brown sugar packed
  • ½ cup granulated sugar
  • 1 large egg + 1 egg yolk
  • tsp vanilla extract
  • ½ tsp baking soda
  • ½ tsp salt
  • cups all-purpose flour
  • 2 cups semi-sweet chocolate chips

Instructions

Instructions:

  • Preheat oven to 350°F (metal pan) or 340°F (if using a dark or coated pan).
  • Mix melted/browned butter with both sugars until glossy and combined.
  • Whisk in egg + yolk, then vanilla.
  • Add salt, baking soda, and flour. Mix just until flour disappears — it’ll be thick.
  • Fold in chocolate chips.
  • Spread evenly into a greased 10x15 pan (you can line with parchment for easy removal).
  • Bake 15–20 minutes, until edges are golden and center looks just set. It should still jiggle slightly when you move the pan.
  • Cool in the pan for at least 30 minutes before removing or decorating.

Notes

  • For extra chew: swap ¼ cup of the flour for bread flour or add 1 Tbsp of light corn syrup.
  • For crisp edges & soft center: bake on the middle rack and rotate the pan halfway.
  • This dough also bakes beautifully as a thick round cookie cake (use a 12" round pan at 350°F for 18–22 minutes).
