In a mixing bowl, combine the rolled oats, pumpkin puree, milk, maple syrup, cinnamon, nutmeg, ginger, and salt. Stir well until the mixture is smooth and the oats are evenly coated with the spices and pumpkin.
Cover the bowl tightly with plastic wrap or a lid and place it in the refrigerator overnight or for at least 4 hours. This allows the oats to absorb the flavors and soften to a creamy consistency.
After soaking, give the oats a good stir to distribute any settled ingredients and check their creaminess. The mixture should be thick, smooth, and invitingly fragrant.
Taste the oats and adjust sweetness or spices if desired, adding a splash more milk for thinner consistency or a drizzle of syrup for extra sweetness.
Spoon the pumpkin spice oats into bowls and optionally top with your favorite toppings like nuts, seeds, or a dollop of yogurt for added texture and flavor.
Enjoy your cozy, creamy pumpkin spice overnight oats, perfect for a cold morning and bursting with autumn flavors.
