Sugar covered Chocolate Cookies

Voilà, today I present you a new recipe for chocoholics: Chocolate cookies with little pieces of two kinds of chocolate. I love them! 
Before they are baked, I roll them in icing sugar. And in the oven – while the cookies are rising – the sugar cover bursts. That’s how the spotted surface is developed. I am sure, you will love these cookies as well.

Ingredients
125 g dark chocolate, chopped for melting
100 g dark chocolate chips or chopped chocolate
100 g milk chocolate, chopped
¼ cup butter
4 eggs (L size) at room temperature
2 cups sugar
1 tsp pure vanilla extract
1 ½ cups flour
½ cup cocoa powder
2 tsp baking powder
¼ tsp salt
½ cup or more of icing sugar

1 cup = 120 g;    ½ cup =   60 g (flour and icing sugar)
1 cup = 225 g;    ½ cup = 115 g (butter and sugar)

Melt the 125 g chocolate and butter in a double boiler. Stir occasionally until the chocolate and butter have completely melted. Set aside to cool.
Combine flour, cocoa, baking powder and salt in a bowl. In another bowl beat the eggs, sugar and vanilla until light in colour – about 3 minutes. Add the chocolate/butter mixture and then stir in the flour mixture. Fold in the chopped chocolate. Cover the bowl with cling wrap and let it cool down for about 2 hours.
Preheat the oven to 165°C.

Moisten your hands with some water and roll the dough into balls (approx. into 3 cm ø ). Roll each ball in the icing sugar until it is covered completely. Place the balls on baking paper spaced approx. 5 cm apart. Bake until the tops are puffed and crinkled approx. 15 – 17 minutes.
