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

In a medium-sized bowl, whisk together the flour, cocoa powder, baking powder, and salt until well combined. Set aside.

In a separate large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.

Beat in the eggs, one at a time, until fully incorporated. Then, stir in the vanilla extract.

Gradually add the dry ingredients to the wet ingredients, mixing until a thick dough forms.

Fold in the chocolate chips until evenly distributed throughout the dough.

Using a spoon or cookie scoop, drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart.

Gently flatten each dough ball with the back of a spoon or your fingers to form a cookie shape.

Bake in the preheated oven for 10-12 minutes, or until the edges are set and the tops are slightly firm to the touch.

Remove from the oven and allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
