It definitely works, even if you might want to cook it "until done." I have a hard time wanting to eat a microwaved egg, keep in mind that microwave wattages vary. It smells like EasyBake and childhood nostalgia and tastes pretty bland (though I may have taken some sugar out because the ratios didn't seem right--they are, don't worry), so you may want to add in those optional chocolate chips. Get creative! This is a good base for whatever midnight cravings you have. And if you don't have self-raising flour (like me) use all-purpose and add a little baking powder.
