Ingredients

- 150 g of flour

- 2 tablespoons of dark cocoa powder

- 50 g of dark chocolate

- 3 eggs

- 1 teaspoon of baking powder

- 150 g of sugar

- 50 g of butter

- 200 ml of milk

- 50g of chocolate chip (white or dark) - optional

Divide the egg whites from the yolks. Start by whipping the egg whites until they become a dense foam. Save it for later.

Cut the butter in small pieces and leave them warming up at room temperature. Melt the dark chocolate in the microwave or in a pan.

Add the yolks in a bowl with the sugar and mix them.

When you get a smooth mixture add the butter and mix again.

When the butter is melted in the mixture add the chocolate and the cocoa powder.

Add the one teaspoon of baking powder to 150g flour. Misure 200ml of milk. Add the flour spoon by spoon into the mixture.

When the mixture is too dense add some milk. Continue to add flour and milk, you should get a smooth mixture.

Add the egg whites, mixing them with a spoon by hands, gently so they won't loose the foam.

Spread some butter in a cake pan and add the mixture. Add the chocolate chip on top (they will fall down while cooking...)

Cook for 35-40 min at 180°C (360F) checking with a wood stick the center of the cake: it should come out dry. Serve room temperature.
