How Many Calories in Overnight Oats?

1 jar (~250 g) has about 310 calories.

Why estimates miss: Overnight Oats is a multi-ingredient dish. Nut butter and honey toppings can quietly double the base oats-and-milk count. Generic calorie apps undercount the hidden oil, sauce and portion — CalDesk AI's photo estimate is tuned to catch exactly this.
