In a bowl or jar, combine the old-fashioned oats, milk, Greek yogurt, honey or maple syrup, dried cranberries, chopped walnuts, vanilla extract, and a pinch of salt.
Stir the ingredients thoroughly to ensure everything is well combined.
Cover the bowl or jar with a lid or plastic wrap.
Refrigerate the mixture overnight or for at least 4 hours to allow the oats to soak and soften.
The next morning, give the Cranberry Walnut Overnight Oats a good stir.
If desired, add more milk to achieve your preferred consistency.
Serve the overnight oats cold, and optionally, top with additional dried cranberries and chopped walnuts.
Enjoy this convenient and nutritious breakfast option that combines the tartness of cranberries with the crunch of walnuts in a creamy oat base!
