Melted chocolate in a water bath. Add the butter, which will melt from the heat of the chocolate. To the mixture, add the powdered sugar and stirred to homogenize the mixture. Add the egg and yolk. Again mix well. Finally comes the flour. All the ingredients are mixed well. Pan 2 shapes custard, for example. Divide dough equally. Bake in a preheated 180C oven for 10-12 minutes. * As you can see I used shapes for cakes, smaller forms of custard, and received four small lava cakes. * This dessert goes great with a scoop of vanilla ice cream.
