The oats within this recipe offer a sponge-like effect which will help to absorb the liquid from the milk and yogurt, resulting in a thick and creamy texture.

Oatmeal is a high-quality source of carbohydrates that provides sustained energy throughout the morning. It is also high in fiber, which can help to regulate digestion.


By using milk in this recipe, you will not only add creaminess but also a good dose of calcium, vitamin D, and other essential nutrients.

Greek Yogurt

The greek yogurt really adds to the overall texture making it a much thicker consistency.

Greek yogurt is a great source of low-fat, low-calorie, protein, and calcium.

Can I add extra protein powder to this recipe?

Yes, this recipe only calls for 1/2 scoop per serving and it will get you 30 g of protein for the whole recipe. If you want you could add a whole scoop of protein to this recipe bringing your total to 45 grams of protein.

What kind of milk can I use in this recipe?

Personally, I use Fairlife 2% milk. You can use any brand, however, I would recommend that you stick with a reduced-fat version.
Also, if you are looking to void dairy feel free to use tree nut milk like almond milk.

How long will these oats last in the fridge?

These oats will last in the fridge for 3-5 days. After that, they start to get a little bit too soggy for my liking. Plus you are running into food safety issues after those 5 days

Can I heat these oats up?

Yes, you can heat these oats up. I would recommend doing so in 30-second intervals so that you don’t overcook them. Once heated, top with an additional banana or chocolate chips.
