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.
We don’t keep bread in the house anymore but occasionally I want cinnamon toast. Nuke a little butter, mix in sugar & cinnamon, enjoy on saltines. It’s a little messy because the sugar and butter won’t completely emulsify but it scratches that itch when I’m baked.
