As usual, this recipe makes enough for multiple servings, in this case four. I cut it down to a single serving because a) it's just me and b) I only had a little more than 1 cup of vanilla ice cream anyway (and no frozen yogurt of any flavour).
This was very sweet, but pretty tasty. Too sweet for me for breakfast, really, but this would make a pretty good dessert. Especially, I suspect, with frozen yogurt.
