Apple Cinnamon Overnight Oats

In a mixing bowl, combine the rolled oats, milk, and Greek yogurt. Stir until everything is well combined.

Add the diced apple, cinnamon, and honey or maple syrup if you're using it. Mix everything together until the apple is evenly distributed.

Transfer the mixture into a mason jar or an airtight container. If desired, top with chopped nuts for added crunch.

Cover and refrigerate overnight, or for at least 4 hours, to allow the oats to soak up the liquid and flavors.

In the morning, give the oats a good stir. Enjoy them cold or warm them in the microwave if preferred. Top with additional apple slices or nuts if desired.
