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