I start by adding the milk, pumpkin puree, maple syrup, and vanilla extract to a mixing bowl. I whisk everything together until it's completely smooth with no lumps left. This step matters because clumpy pumpkin can leave pockets of flavor instead of an evenly spiced pudding.
Next, I stir in the pumpkin pie spice and a small pinch of salt. I always taste the mixture at this point and adjust the sweetness if needed. This is also when I mix in nut butter if I'm making a pumpkin butter chia pudding version.
I add the chia seeds last and whisk them in thoroughly so they don't clump together at the bottom. I like to let the bowl sit for five minutes and give it one more stir before covering it, since that second stir helps prevent any settling.
I transfer the mixture into jars or cover the bowl with a lid, then place it in the fridge for at least four hours. Overnight works best for me because the texture turns out thicker and creamier by morning.
Once it's chilled, I give the pudding a good stir to loosen it up. If it feels too thick, I add a splash more milk. If it's too loose, I let it sit for another 30 minutes.
Finally, I top mine with whatever I'm craving that day, whether it's granola, pecans, or a dollop of yogurt. This is the fun part where the pudding really becomes your own.
