Brown Butter Brown Sugar Cookies: Chewy Chocolate Chunk Heaven!

Instructions:

1. Melt butter in a saucepan over medium heat. Cook, swirling occasionally, until it turns a nutty brown color and has a fragrant aroma. Remove from heat and let cool slightly.
2. In a large mixing bowl, combine brown sugar, granulated sugar, and slightly cooled brown butter. Beat until light and fluffy.
3. Beat in the egg and egg yolk, one at a time, then stir in the vanilla extract.
4. In a separate bowl, whisk together the flour, baking soda, and salt.
5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix!
6. Fold in the chocolate chunks until evenly distributed.
7. Cover the dough and chill in the refrigerator for at least 30 minutes (or up to 24 hours).
8. Preheat oven to 350°F (175°C). Line baking sheets with parchment paper or silicone baking mats.
9. Scoop rounded tablespoons of dough onto the prepared baking sheets, leaving space between each cookie.
10. Bake for 10-12 minutes, or until the edges are golden brown and the centers are still slightly soft.
11. Let the cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
