Pretty good. It was difficult to spread the chocolate icing on top of the marshmallows without mixing the two together; mine came out slightly marbled on top but it still looked pretty. I liked this recipe but as the previous reviewer said it is definitely on the sweet side, even a carb junkie like me was in sugar overload!

One need only read the recipe ingredient list to realize the sugar content is astronomical! Regardless, the end product is very tasty--will certainly satisfy any sweet tooths in your house.
