Smash the chocolate into small pieces and transfer to a bowl, add 1 cup of butter. Place in a water bath and melt. Stir until smooth and transfer to a large bowl.

Preheat the oven to 160 degrees. Sift the sugar and flour and add the chocolate. Then gradually enter and leave the dough balls for 30 minutes at room temperature.

Take Muffin Pans and put into each hole paper molds. Fill the molds and bake the dough for 30-35 minutes until tender.

Bon appetit!
