Preheat your oven to 350°F (175°C) and line a large baking sheet with parchment paper.

Cream together the butter, granulated sugar, and brown sugar until smooth and fluffy, about 3-5 minutes.

Beat in the eggs, one at a time, then stir in the vanilla extract until combined.

In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt.

Gradually blend the dry ingredients into the wet mixture and fold in the chocolate chips.

Scoop rounded tablespoons of dough onto the prepared baking sheet, spacing them 2 inches apart.

Bake for 10-12 minutes, until the edges are set but centers are still soft.

Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack.
