This recipe technically calls for instant oats, but it also works with leftover oatmeal.

You’ll need the oatmeal to be pretty thick, so this is best made the next day when the oats have been in the fridge for a while.

21. The Leafy Cafe Leftover Oatmeal Cake

Need a soft, chewy, sweet cake in a rush? Try this leftover oatmeal cake with banana and coconut.

It’s a simple blend of canola oil, sugar, mashed banana, soaked flaxseeds, and oatmeal.

22. Strawberry Oatmeal Smoothie

Power up your morning on the go with this strawberry smoothie recipe.

Juicy and sweet fruit with hearty oats is sure to keep you going until lunch. Or try it as an afternoon pick-me-up that’s both energetic and tasty.

Enjoy it with a bowl of fruit salad, or pack it away to make those deskside lunches extra enjoyable.

23. Cooked Oatmeal Scones

Like the biscuits above, these scones aren’t as light and fluffy as you may be used to.

But again, this is a fantastic way to use up leftovers and get something tasty to boot.

Just keep in mind, if you added spices or flavor to the oatmeal, the scones will take on that flavor too. So it’s best with lightly sweetened oatmeal.

24. Baked Oatmeal

Baked oatmeal is like a warm hug, and it’s the perfect balance of nostalgia with hints of cinnamon and vanilla.

Add some wholesome banana and coconut oil, and it’s just what you need for a snack or quick breakfast.
