It's so unhealthy it's fascinating, a little like instant noodles: you look at it going "is this even food?" even as you eat it. You go back and buy more. My maple doughnut was excessively good and I ended up scraping the smears of icing off the box on the way home.

However, the amusement of feeding them to a borderline diabetic and watching the reaction is unparalleled :)
