Only five ingredients and five minutes to make this banana overnight oats recipe. It’s a quick and easy vegan breakfast to prep ahead.

Banana overnight oats are going to be your new favorite breakfast. I love easy, make ahead breakfasts – breakfasts that you could make the night before, the weekend before, and they are just chillin’ waiting for you in the morning.

What I love about this recipe is it is totally customizable! Once you have the base ratio for these overnight oats, you can add in whatever mix-ins you like!

What are overnight oats?

You make overnight oats by mixing rolled oats with liquid and other mix-ins to add sweetness and flavor. Allow it to sit in the fridge for at least two hours or, more likely, overnight. And, viola! Easy breakfast in the morning prepped ahead for you!

The best part is no cooking is required! You can eat it cold right out of the fridge, or pop it in the microwave to heat it up.

Ingredients and substitutions to make banana overnight oats:

  • Banana: Just a half of the banana to make the recipe and you can save the other half to slice for the topping!
  • Milk: I used oat milk, but you can use any nut milk or traditional dairy milk!
  • Rolled Oats: I always go for gluten free rolled oats. Other oats like quick oats, instant oats, or steel cut oats don’t soak up the liquid as much as traditional rolled oats, so rolled oats are the bets option.
  • Hemp Hearts: add some extra plant-based protein. You can leave these out completely or sub in another seed like flax seeds or chia seeds, or chopped nuts.
  • Agave Nectar: you can sub in any sweetener here. Honey or maple syrup would be a great sub!

Overnight Oats Ratio:

The base of this recipe is easy to remember! 1:1 is the best overnight oats ratio. If you use 1/2 cup oats, use 1/2 cup liquid. If you use 1 cup oats, then bump it up to 1 cup milk.

How long do overnight oats need to soak?

If you’re in a pinch, only 2 hours is all you need. But, I prefer to let them sit overnight so the oats can really soak in all the flavors.

Allowing them to sit overnight lets the oats really soak in all the liquid, so if allow less soak time, the end result will just be a bit more liquid-y.

Toppings are my favorite!

Have fun customizing the toppings on your banana overnight oats! I topped mine with some sliced banana, a drizzle of peanut butter, and some chopped peanuts.

You could definitely add some berries to make these banana and berry overnight oats. Or, add some chocolate chips, peanut butter chips, even eat them plain!
