I occasionally buy single serving ice cream containers. I think Breyers and Hagan Daaz both make them (or maybe Ben and Jerry's?) They are usually about 200 cals for a little container. I eat them with a baby spoon. They also come with a little plastic spoon in the container.
A container is a pint and there are four half cup servings in a pint. 120 calories for half a cup is pretty good bang for my calorie budget. I often have 200 calories at the end of the day to play with.
It's not ice cream, its a sorbet so it's basically like a frozen juice bar just not on a stick and not as hard. I find it a delightful alternative to skinny cow treats (which I also love but variety is nice!)
my only sweet indulgences right now are SF Jello or warmed up chocolate almond breeze or soy slender. (the warmed almond breeze/soy slender is my favorite!)
I DO love the HaagenDaaz lemon sorbet tho...
for those of you who can indulge , Dreyers Slow Churned ice creams are great. 100 to 130 cal per serving.... I haven't tried one I didn't like.
Stony Field farms makes some yummy fat free frozen yogurts with active cultures and everything.
