Making Overnight Oats

If you’re new to overnight oats, they are what they say they are: oats that you soak overnight in the fridge. No cooking required! Instead of standing over the stove to cook them, you can eat these straight out of the jar in the morning.

If cold oatmeal seems like a travesty, stick these in the microwave for about a minute to take the chill out or let them stand on the counter until they come to room temperature

When you’re making overnight oats, you want to use rolled oats. Steel cut oats need cooking as far as I know, though soaking them overnight does reduce the cooking time dramatically. The Kitchn has a great piece that demystifies the difference between rolled, old fashioned, steel cut, quick, and instant oats.

Peanut Butter and Banana Overnight Oats

I make overnight oats from time to time but they were by no means a habit. Usually I keep it simple with some oats, some soy milk, and maybe some chia seeds, but for this recipe I wanted to step it up a little bit. These overnight oats are based on this sandwich, but they’re much, much healthier.

My goal with overnight oats is ease, so I went with a foolproof combo: peanut butter and banana. Making them couldn’t be easier. Just mix, mash, and spoon into your overnight containers.

If you don’t need individual servings, you could even mix this up in a large glass bowl with a lid, and spoon out your portion in the morning.

Notes on Sugar

How much sweetener you’ll need depends on a number of factors:

Your bananas. The riper the banana, the sweeter it is. If your bananas are super ripe, I’d skip the maple syrup until the oats are mixed. You can always add, but you can’t take away.
Your milk. I used regular soy milk, which is a little sweet on its own. With unsweetened milk, you might want to compensate with more sugar.
Your peanut butter. Some peanut butters contain added sugars, and some don’t. You may need less maple syrup if you use sweetened peanut butter.
Your personal tastes. I tend to like things that are less sweet, but I know some folks need more sugar before they can taste the sweetness. That is totally okay. Follow your tastebuds!

If you’re watching your sugar intake, you can also sweeten these overnight oats with stevia. I am not crazy about how stevia tastes, so I can’t speak to how much you’d use. Like with the maple syrup, start with just a touch, and go from there.
