What are Coffee Overnight Oats?

Coffee Overnight Oats are a make-ahead breakfast where rolled oats are soaked overnight in a mixture of brewed coffee, milk (or dairy-free alternative), and sweetener. By morning, the oats absorb the liquid, becoming soft, creamy, and full of flavor. They’re a simple, healthy winter breakfast idea, energizing, comforting, and made without turning on the stove. You can even prepare multiple jars in advance for the week ahead.

This recipe is also customizable: want it sweeter? Add maple syrup. Need extra protein? Mix in Greek yogurt or protein powder.
