Combine Ingredients:
In a mason jar or airtight container, mix rolled oats, milk, pumpkin puree, Greek yogurt, chia seeds, maple syrup, pumpkin pie spice, cinnamon, vanilla extract, and a pinch of salt.
Mix Thoroughly:
Stir well until all ingredients are evenly combined and the mixture is smooth.
Refrigerate Overnight:
Seal the container and refrigerate for at least 6 hours, preferably overnight. This allows the oats and chia seeds to absorb the liquid and thicken into a creamy consistency.
Serve:
In the morning, give the oats a good stir. If too thick, add a splash of milk to loosen it up.
Add Toppings:
Finish with your favorite toppings — almond butter, granola, nuts, or chocolate chips — and enjoy cold straight from the jar!
