01 - In a medium saucepan over medium heat, melt the butter. Continue cooking, swirling often, until the butter foams and turns deep golden with browned milk solids at the bottom, about 4 to 5 minutes. Transfer immediately to a mixing bowl and let cool for 10 minutes.
02 - In a medium bowl, whisk together the flour, baking soda, and fine sea salt until evenly distributed.
03 - To the cooled brown butter, add the brown sugar and granulated sugar. Beat until well combined. Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.
04 - Gradually stir in the dry ingredient mixture until just combined. Do not overmix.
05 - Fold in the chocolate chips, chopped honey pretzels, caramel pieces, and 1/2 teaspoon flaky sea salt until evenly distributed throughout the dough.
06 - Cover the dough and refrigerate for at least 30 minutes, or up to 24 hours for best flavor and texture development.
07 - Preheat the oven to 350°F. Line baking sheets with parchment paper.
08 - Scoop 2-tablespoon portions of dough, about golf ball size, onto the prepared baking sheets, spacing them 2 inches apart.
09 - Bake for 11 to 13 minutes, until the edges are golden and the centers are just set. Remove from the oven and immediately sprinkle with additional flaky sea salt.
10 - Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
