In a mason jar or similar container, combine the oats, almond milk, cottage cheese, chia seeds, cinnamon, and vanilla extract. Stir thoroughly for about 30 seconds to ensure the cottage cheese is evenly distributed throughout the mixture and all the dry ingredients are well incorporated. I find that breaking up any clumps of cottage cheese with the back of your spoon helps create a more uniform texture in the final dish.

Cover the jar tightly and refrigerate for at least 4 hours, though overnight (8-12 hours) is ideal. During this time, the oats absorb the liquid and soften while the chia seeds expand and create a creamy, pudding-like consistency. The longer chilling time allows all the flavors to meld together and develop. When you're ready to eat, remove from the refrigerator and give it a good stir—I like to loosen it up with a splash of almond milk if it's thicker than I prefer.

Transfer the overnight oats to a bowl if desired, or eat straight from the jar. Add your choice of toppings such as fresh berries, granola, nuts, a drizzle of honey, or a dollop of Greek yogurt. Serve immediately while chilled.
