Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Fold in the dark chocolate chips and caramel bits.
Drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart. Sprinkle each cookie with a pinch of sea salt.
Bake in the preheated oven for 10-12 minutes, or until the edges are set and the centers are still slightly soft.
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a cooling rack to cool completely.
