Chop the chocolate and melt it with the butter at low heat. Beat the eggs, egg yolks and 60 g sugar with the whisk of the hand mixer for about 5 minutes until creamy. Stir in flour and chocolate.
Fill 4 greased and sugared moulds (each containing approx. 200 ml) 3/4 full with it. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 12-15 minutes. In the meantime, crush blueberries, 1 tablespoon of sugar and lemon juice with a hand blender to a creamy ice cream.
Freeze ice immediately. Serve the finished pudding hot with ice cream.
