Melt chocolate and butter in a water bath.
Beat the egg with a fork of sugar and add the flour.
Add the cooled chocolate and butter to the egg and mix, add cognac or vanilla if desired.
We have two cupcake doughs, grease the molds with butter, if the silicone molds can not be lubricated. Sort the dough into shapes.
Put in a preheated oven to 160 degrees for 12-15 minutes, or when the dough starts to rise, keep in the oven for 5 minutes, you don’t need longer, otherwise there will be no liquid filling. Before serving, you can sprinkle with powdered sugar.
Hot chocolate cake with liquid filling turns out to be surprisingly gentle, tasty with a rich chocolate flavor. For the preparation of such a cake, you can use any milk chocolate or with nut additives, but if you want to get a really real cake with liquid filling, then opt for dark chocolate, then the taste will be more intense and full. Serve hot with a scoop of ice cream or just for tea or other drinks.
