In a mason jar or medium-sized container, pour in 3/4 cup of your choice of milk.

Add 1/2 cup of rolled oats and 1 tablespoon of chia seeds into the milk. Stir gently to submerge the oats.

Drizzle in 1.5 tablespoons of maple syrup and sprinkle 1.5 teaspoons of ground cinnamon over the top. Add 1/2 teaspoon of vanilla extract.

Cover the container with a lid or plastic wrap and refrigerate for at least 6 hours or overnight.

After chilling, stir the mixture. If too thick, add a splash of milk to achieve desired consistency.

Serve directly from the jar or transfer to a bowl. Top with fruits, nuts, or more maple syrup if desired.
