Preheat your oven to 350°F and line baking sheets with parchment paper.
In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy, about 3 minutes.
Beat in eggs one at a time, then add vanilla extract and mix until well combined.
In a separate bowl, whisk together flour, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing just until combined.
Fold in the crushed pretzels, caramel bits, and chocolate chips until evenly distributed.
Drop rounded tablespoons of dough onto prepared baking sheets, spacing them about 2 inches apart.
Sprinkle a pinch of flaky sea salt on top of each cookie.
Bake for 10-12 minutes, until edges are golden brown but centers still look slightly underdone.
Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
