Add the yogurt, milk, banana, pureed pumpkin, vanilla, pumpkin pie spice, chia seeds and maple syrup to a blender and blend until completely smooth.
Pour into a glass and top with whipped cream or Greek yogurt whip and more pumpkin pie spice if desired.
Drink right away (the shake will thicken as it sits. If prepping for later, give it a good shake, or stir in a bit of milk to thin it out, if needed, before drinking!)
