I think that the longer you cook them in the pot the less greasy it will appear.
It includes peanut butter too! They make a nice snack and even a nice power breakfast treat if you're in a hurry.
Whenever I make chocolate oats I tend to throw in whatever catches my fancy.
However, when serving, the oat part crumbled badly, after only being out for a few minutes: making for poor presentation and was very messy to pick up and eat.
Cutting them at refrigerated temperature was fine.
