Preheat your oven to 350°F (175°C).
In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until the mixture is light and fluffy.
Add the eggs, one at a time, mixing well after each addition, then stir in the vanilla extract.
In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
Fold in the mini chocolate chips and sprinkles with a spatula.
Drop tablespoon-sized scoops of dough onto a lined baking sheet.
Bake in the preheated oven for 10-12 minutes or until the edges are set.
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack.
