Step 1

Preheat the oven to 350 degrees F. Line a large baking sheet with parchment paper.

Step 2

In a stand mixer with the beater blade attachment, beat the butter, granulated sugar, brown sugar and chocolate until smooth. Add the eggs and mix until fully combined. Sift together the flour, cocoa powder, baking powder and salt in a bowl and add slowly to the batter until mixed. Add the vanilla and fold in the chocolate chips.

Step 3

Drop by generous spoonfuls onto the prepared baking sheet, about 2 inches apart. Bake for 15 minutes. Transfer to a wire rack to cool.
