Preheat your oven to 350°F (175°C).

Whisk together the dry ingredients in a bowl: flour, cocoa powder, baking powder, and salt.

Beat in another bowl granulated sugar, brown sugar, eggs, and vanilla until fluffy.

Fold the dry ingredients into the wet mixture until just combined.

Scoop the dough into small balls, roughly 1-2 inches in size, and roll them in powdered sugar until fully coated.

Place the dough balls on parchment-lined baking sheets, spacing them apart. Bake for 10-12 minutes or until they are slightly puffed.
