Preheat your oven to 350°F (or line your air fryer with parchment if you're feeling modern).
In a large mixing bowl, cream together the butter, granulated sugar, and brown sugar until light and fluffy—singing optional.
Beat in the eggs, one at a time, then stir in the vanilla.
In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt.
Gradually stir the dry ingredients into the butter mixture. (Prepare for a mini arm workout here.)
Fold in the chocolate chips. Try not to eat half the dough at this point. I dare you.
Drop spoonfuls of dough onto a baking sheet about 2 inches apart.
Bake for 8–10 minutes, just until the tops look set but the centers are still soft. Do not overbake. (Unless you like crunchy. Then go wild.)
Cool on the pan for 5 minutes before transferring to a wire rack. Or just hover over the pan and eat them warm. We don’t judge.
