Break up the chocolate and butter and put into a deep bowl. Microwave at 500 W for 1:30.
The chocolate will retain its shape, but it will be soft. At this point, you can mix it with a whisk until smooth.
Once it becomes smooth, add the egg and mix well. Add the flour and mix again (it should become like this).
Pour into the cups and lightly tap the edges and drop onto the table to break up any bubbles in the batter. Bake in an oven preheated to 180°C for 10 minutes and serve!
When freshly baked, the inside will ooze out.
If cooled to room temperature, it's soft and smooth like truffles.
If you chill it well in the refrigerator before eating, it become rich.
