Overnight oats calories: by liquid, fruit and add-ins
Overnight oats start with a simple base of dry oats soaked in liquid, then become whatever you build on top. The oats and milk set a calm, fiber-rich foundation, while the real swing comes from your liquid choice and the add-ins — banana, peanut butter, berries and chia. Pick your liquid and toggle the toppings to see how your jar adds up.

FAQ
How many calories in overnight oats?
A basic jar with 1/2 cup of dry oats and milk is about 210 kcal, with roughly 9 g of protein and 7 g of fiber. With banana it is closer to 315 kcal, and a loaded jar with peanut butter and chia can pass 500 kcal.
How many calories in overnight oats per serving?
A standard one-jar serving made with oats and milk is around 210 kcal. The exact number depends mostly on your liquid and add-ins — almond milk runs lighter, while Greek yogurt, banana and peanut butter add up quickly.
