Ok, I tried it and it was good! Not gourmet, but tasty and considering it just takes 3 minutes in the microwave one cannot complain. It puffed dangerously above the rim while cooking but collapsed upon removal. The chocolate chips sank to the bottom but when I tipped it out they made a sort of chocolately topping. (It uses no baking soda/powder for those who asked)Use a BIG mug:) Would be REALLY good warm with ice cream.
