Note: I freeze my pumpkin ahead of time because it makes it both cold and thick. Just place the pumpkin puree in 2 tablespoon increments on a cookie sheet. Freeze for an hour or two then grab 2 "pucks" and place in the blender. You don't have to freeze it but you might want to add a few ice cubes to make it thicker.
Put everything else in the blender and blend on high for 1 minute until nice and smooth. The chia seeds really need to be blended to make the shake thick.
Please note if you need to find any of these ingredients you can find them on my Amazon page.
