01 - Melt butter in a medium saucepan over medium heat. Continue cooking, stirring frequently, until butter foams and turns golden brown with a nutty aroma, approximately 5–7 minutes. Remove from heat and let cool for 10 minutes.
02 - In a large mixing bowl, combine browned butter, brown sugar, and granulated sugar. Beat until smooth and well combined.
03 - Add eggs and vanilla extract to the butter mixture. Mix until fully incorporated and smooth.
04 - In a separate bowl, whisk together flour, baking soda, baking powder, and kosher salt until evenly distributed.
05 - Gradually add dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
06 - Gently fold in chocolate chips, pretzels, and caramel bits until evenly distributed throughout the dough.
07 - Cover dough and refrigerate for at least 30 minutes, up to 24 hours for deeper flavor development.
08 - Preheat oven to 350°F. Line baking sheets with parchment paper.
09 - Scoop 2-tablespoon portions of dough onto prepared baking sheets, spacing 2 inches apart to allow for spreading.
10 - Bake for 11–13 minutes, until edges are golden brown but centers appear slightly underbaked for a chewy texture.
11 - Immediately sprinkle hot cookies with flaky sea salt. Cool on baking sheets for 5 minutes, then transfer to a wire rack to cool completely.
