How I make it
Preheat the oven to 375°F (190°C).
Melt the chocolate and butter together, in the microwave or over a water bath.
Add the sugar and let cool briefly.
Add the eggs one at a time, stirring well with a wooden spoon after each.
Add the flour and stir well until smooth.
Pour into a pan and bake for 22 minutes. The center should be very soft.
Take out of the oven, quickly release the cake from the pan and let it cool and rest.
