Chop the chocolate coating, melt over a hot water bath, let it cool down a little. Mix flour and cocoa. Separate the eggs. Beat butter, sugar and chocolate coating with the whisk of the hand mixer until foamy. Gradually stir in the egg yolks.
Beat the egg whites until stiff, adding vanilla sugar and salt. Fold flour mixture and beaten egg white into the egg-butter cream. Fold in the giottos. Pour into greased and sugar-scented moulds (approx. 200 ml content). Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 20-25 minutes. Mix sour cream and milk with a whisk. Add sauce powder while stirring and stir vigorously for about 1 minute. Turn out the ramekins onto 4 plates, carefully turning over the soufflés. Dust with icing sugar.
