Combine chocolate and butter in a bain marie. Turn on the medium heat and cook the mixture. Stir the mixture constantly until it is melted and fully combined together. The bottom of the bowl with chocolate should not be touching the water.
Whisk the eggs and sugar in a separate bowl. Then add flour and whisk to combine so there are no lumps.
Combine the warm chocolate and the egg mixtures together.
Brush the baking molds with soft butter thoroughly.
Distribute the mixture to the molds evenly. Bake for 10 12 minutes in a preheated oven (180 degrees). Drizzle some topping on a plate, put the tortino on top, dust it with powdered sugar and serve with some ice cream on the side.
