Preheat the oven to 200 °C.

With a mixer, beat the eggs with the sugar.

Melt the butter with the chocolate until smooth (a microwave works well).

Combine both mixtures and beat again with the mixer.

Turn off the mixer, sift in the flour, gently fold it in and divide the batter among molds greased with vegetable oil - you'll get 4 ceramic molds.

Bake for exactly 10 minutes. Remove, let cool for a couple of minutes and turn out onto a plate.

Serve hot with powdered sugar, a scoop of ice cream and berries.
