These cinnamon overnight oats are hearty, delicious, and comforting for a perfect breakfast treat any time of year.

When it comes to overnight oats, you can get super simple with plain overnight oats, or you can create a fun and festive extravaganza with something like birthday cake overnight oats, but most of the time I just want something in the middle.

Not too fancy, not too plain, just right.

In this cinnamon overnight oats recipe, that’s exactly what you’ll get.

What Are Overnight Oats?

Overnight oats are a more recent sensation, but they are the perfect solution to a busy morning so if you are someone who needs a “grab and go breakfast,” they are for you!

Basically, they are an oat dish that is not cooked on the stove, but rather stored in the fridge overnight (or 8+ hours, but they’re called overnight oats so let’s say overnight) while the oats and liquid combine to make the oats edible and not dry.

Do You Eat Overnight Oats Warm or Cold?

Overnight oats are really designed to be eaten cold, as the yogurt doesn’t taste that great when heated up.

However, you can eat them warm if that’s your thing, there’s no law against it. Try it!

Ingredients for Cinnamon Overnight Oats

To make this recipe, you’ll want to gather up:

  • greek yogurt – I use full-fat and this brand, but you can use your favorite kind
  • water – this is going to help the oats actually become edible as they soak up the liquid overnight
  • rolled or steel cut oats – the main attraction, I use this kind
  • cinnamon – to make these cinnamon oats, rather than plain. This is a great bulk buy option
  • honey – to act as a sweetener (I use this all-natural brand)

Storing Overnight Oats

There are different options when it comes to storing the overnight oats, including mason jars, colorful bowls with plastic wrap over it, and mugs with plastic wrap over it.

What I do is make the oats in the bowl, as I find it easier to mix that way, and then I pour it into a sloth mug with some plastic wrap.

In the morning, simply take off the plastic wrap, grab a spoon, and enjoy!

I make sure to eat my oats within 48 hours of initially putting them into the fridge, but they’re better the day right after making them.

Can I Make Substitutions in these Overnight Oats?

Yes, you can make substitutions in these overnight oats.

To make them dairy-free, substitute water for the Greek Yogurt (on top of the water already in the recipe).

To make them thinner, substitute the Greek Yogurt with milk.

To make them even creamier, add more Greek Yogurt.

You can leave out the honey if you want, but know that it acts as a sweetener so you’ll have a bit more of a savory overnight oats.

  • For thinner oats, substitute the greek yogurt with milk.
