Place all of the ingredients in a high-speed blender.
Blend on high until smooth, 1-2 minutes.
Serve plain or with non-dairy whipped topping. I like sprinkling a dash of cinnamon or pumpkin pie spice on top.
Notes
* If you prefer to use fresh homemade pumpkin purée, be sure it’s similar to the consistency of canned pumpkin purée.** If you don’t have pumpkin pie spice, combine ½ tsp cinnamon, ¼ tsp nutmeg, ¼ tsp ginger, and a dash of cloves.
