Heat the oven to 180C/fan 160C/gas4. Butter 6 medium ramekins. Melt the chocolate with the butter in a bowl over simmering water or in a microwave. Beat the eggs with the sugar until they are very light and fluffy and then fold in the flour. Fold in the chocolate mixture.
Divide between the ramekins(put them in the fridge at this point if you are making ahead).Bake for 8-12minutes. The soufflés should rise and form a firm crust but you want them still to be slightly runny in the middle. Serve with cream. Serves 6
