In a medium bowl or a jar with a lid, combine the pumpkin puree, milk, maple syrup, pumpkin pie spice, vanilla extract, and salt. Whisk everything together until the mixture is completely smooth and well blended.
Sprinkle in the chia seeds and stir them into the pumpkin mixture. Make sure they are evenly distributed so they can absorb the liquid properly.
Let your mixture sit for about 10 minutes. Then, give it another thorough stir to break up any chia seed clumps and ensure an even texture.
Cover the bowl or jar and place it in the refrigerator. Allow it to chill for at least 4 hours, or even better, let it sit overnight. This time lets the chia seeds expand and create that wonderfully thick, pudding-like consistency.
Once perfectly chilled and thick, spoon your healthy pumpkin chia pudding into serving bowls or glasses. Add any desired summer-fresh toppings, and enjoy this easy, nutritious treat!
