When I want a little sweet treat I make smoothies.
My base is always frozen banana + milk + oats then do one of these:
Cinnamon + vanilla
Pumpkin + pumpkin spice+ brown sugar
Strawberries/blue berries
Cost like under a dollar to make a good cup and they are pretty filling.
Vanilla yogurt with crisp rye bread / tack crumbled into it, with bilberries (forest blueberry). The sour crunchy tack, vanilla and the sweet berries compliment each other nicely.
Oh yes! Yogurt with some crunch and fruit is just SOOO good, and you can get a like $4 tub of yogurt that lets you eat some every day for a week.
