In a medium bowl or mason jar, whisk together the milk and almond butter until smooth and well combined, ensuring no clumps remain.
Add the rolled oats, Greek yogurt, honey, vanilla extract, and sea salt to the milk mixture. Stir thoroughly until all ingredients are evenly distributed.
Cover the bowl or seal the jar with a lid. Refrigerate for at least 6 hours or overnight, allowing the oats to fully absorb the liquid and soften.
In the morning, give the oats a good stir. If the mixture is too thick for your liking, add a splash of milk to reach your desired consistency.
Transfer to a serving bowl or eat directly from the jar. Top with your choice of sliced almonds, fresh berries, banana slices, or an extra drizzle of honey.
Enjoy cold, or warm in the microwave for 45-60 seconds if you prefer a cozy porridge-style breakfast.
