For overnight oats with a little cottage cheese texture, you can mix everything directly in a jar. For ultra-creamy oats, blend the cottage cheese, milk, maple syrup, and vanilla until smooth before proceeding.
Add the rolled oats, cottage cheese mixture, chia seeds, cinnamon, and a small pinch of salt to a jar or airtight container. Stir thoroughly until all of the oats are coated in liquid.
Cover the container and refrigerate for at least 4 hours, preferably overnight.
The next morning, give the oats a thorough stir. If they are thicker than you prefer, add a splash of milk.
Top with fresh fruit, nut butter, nuts, granola, or another drizzle of maple syrup. Serve chilled or warm them briefly if you prefer hot oatmeal.
