In a small bowl combine all-purpose flour, baking powder and a pinch of salt. In a large bowl or in a bowl of a stand mixer beat the eggs, white and brown sugar until you get a nice, pale mixture. Add the melted chocolate and butter and continue to mix. While constantly mixing with an electric mixer or in a stand mixer gradually add in the dry ingredients to get a nice, thick mixture.

shape into cookies
Preheat your oven to 180 °C / 350° F. Between your hand roll the dough in a walnut sized ball. (approx. 3 cm in diameter or 20g). Place on a large baking sheet, lined with parchment paper. Make sure to leave enough space between each cookie, because they will spread. Gently press the cookie down just to prevent them from rolling.
Place the baking sheet with cookies in your oven and bake for about 10 minutes at 180 °C / 355 °F. Transfer baked chocolate brownie cookies to a wire rack to cool. Serve or store in a cookie box for up to 14 days.
