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.
Not sure if this counts as “little” because it has to go into the oven for 45mins… But it’s assembled in under 5 minutes and you can get rid of your old bananas that already turned brown:
Banana bread
4 Bananas, 80ml oil, 80g sugar, 250g flour, 2tsp baking powder, 1tsp vanilla sugar, some chocolate (drops).
Smash the bananas, mix in all the other ingredients to a smooth dough. Find some chocolate from christmas that’s still laying around in the house, smash it too and mix it in.
Bake it at 170°C. Takes 40-50min in a loaf pan. Don’t forget to grase the pan before or use baking parchment.
