Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats.
Cream Butter and Sugars:
In a large bowl, beat the softened butter, granulated sugar, and brown sugar together until light and fluffy.
Add Wet Ingredients:
Mix in the eggs, one at a time, followed by the vanilla extract, until fully combined.
Combine Dry Ingredients:
In a separate bowl, whisk together the cocoa powder, flour, baking soda, and salt.
Mix the Dough:
Gradually add the dry ingredients to the wet mixture, mixing until just combined. Stir in the chocolate chips and caramel bits.
Shape the Cookies:
Scoop about 1.5 tablespoons of dough and roll into balls. Place the dough balls on the prepared baking sheets, spacing them about 2 inches apart.
Bake:
Bake in the preheated oven for 10-12 minutes, or until the edges are set but the centers look slightly underbaked. The cookies will firm up as they cool.
Sprinkle with Sea Salt:
Immediately after removing the cookies from the oven, sprinkle each with a pinch of flaky sea salt.
Cool:
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
