As I mentioned before, when I have to make more servings I find it easier to mix up the batter in a bowl.
Put all the dry ingredients in a bowl and whisk well to mix. Add the grated chocolate to this and whisk again to mix well.
Put all the wet ingredients in another bowl and whisk very well to incorporate a bit of air. Now add to the dry ingredients and whisk well some more.
Divide the batter equally between four microwave safe mugs. Sprinkle the extra grated chocolate on the batter, equally among the four mugs. Cook the cakes, one mug at a time, for 2 minutes 20 seconds at 60% power. When done, the cakes should look slightly dry on the top.
This is the time it took for the cakes in my microwave. How long the cakes take to cook would depend upon the wattage of your oven. It should take anything from about 1 1/2 minutes. Check the time with the first cake and adjust as required.
It is important to cook the cakes longer at a lower power; otherwise the cakes will become rubbery in texture. Also remember the cakes will continue to cook after the microwave oven has switched off.
Serve these cakes warm with vanilla, strawberry, coffee or any other flavour of ice-cream which would pair well with chocolate. This recipe serves.
