Choose your container: Use a 12–16 ounce jar or lidded container. A wider opening makes stirring easier.

Measure the base: Add 1/2 cup rolled oats, 1 tablespoon chia seeds, and a small pinch of salt to the jar.

Add the liquid and creaminess: Pour in 1/2 cup milk and 1/3 cup plain Greek yogurt. This combo gives the oats a rich, pudding-like texture.

Flavor it: Stir in 1–2 teaspoons maple syrup, 1/2 teaspoon ground cinnamon, and 1/2 teaspoon vanilla extract. Adjust the sweetness to taste.

Prep the apple: Core and chop 1/2 to 1 small apple into small cubes. Leave the skin on for color and fiber. Add most of it to the jar, saving a few pieces for topping.

Stir well: Mix everything thoroughly so the chia seeds don’t clump and the spices are evenly distributed.

Chill overnight: Seal the container and refrigerate for at least 4 hours, ideally 8–12. The oats and chia will absorb the liquid and thicken.

Finish and serve: In the morning, give it a good stir. If it’s too thick, add a splash of milk. Top with the reserved apple, a sprinkle of cinnamon, and a handful of chopped nuts for crunch.

Optional warm-up: If you prefer it warm, microwave for 30–60 seconds, then stir. Add more milk as needed.
