Preheat the oven to 180°C and line 2 baking sheets with parchment paper.

In a bowl mix the flour with cocoa powder and baking powder.

Melt chocolates and butter in a makeshift double boiler or in the mircowave.

In the bowl of a stand mixer beat the eggs with sugars and a pinch of salt until thick and creamy. Reduce the speed and mix in the melted chocolate.

Sift the powders and fold them into the chocolate batter using a spatula, without overmixing. The batter should have the consistency of the brownie one.

Using an ice cream scooper, scoop the batter onto prepared baking sheets about 4-5 cm apart.

Bake brownie cookies for about 13-15 minutes. Don’t overbake them.
