Brown Butter Raspberry Chocolate Chip Cookies

Preheat the oven to 350° F. Line a baking sheet with parchment paper.Add the butter to a skillet set over medium heat. Cook until the butter begins to brown, about 3-4 minutes. Remove from the heat and transfer to a heatproof bowl. Let cool 5 minutes or so. To the brown butter, mix in the brown sugar, granulated sugar, eggs, and vanilla, mixing until smooth. Add the flour, baking soda, and salt. Gently fold in the chocolate and raspberries, do not overmix.Roll the dough into rounded tablespoon size balls and place 2 inches apart on the prepared baking sheet. The dough may be a little wet from the berries. Gently flatten the dough down. Bake 8 minutes. Remove from the oven, rotate and tap the baking sheet on the counter 1-2 times to flatten. Bake another 2-3 minutes or until the cookies are just beginning to set on the edges.Let the cookies cool on the baking sheet. They will continue to cook slightly as they sit on the baking sheet. Sprinkle with flaky salt (if desired). Eat warm (highly recommended) or let cool and store in an airtight container for up to 4 days.
