Add smoothie ingredients to blender. Blend well, about 20 seconds.
Pour into serving cups. Sprinkle with extra cinnamon, if desired. Each smoothie recipe will make about 2 cups.
Notes
Pumpkin pie spice can be found premade in the grocery store, but it is so easy to make your own.
1 teaspoon ground cinnamon
1/4 teaspoon ground nutmeg
1/4 teaspoon ground ginger
1/8 teaspoon ground cloves
Mix well before measuring. This recipe makes just over 1 1/2 teaspoons, which will be enough for 1 batch of pumpkin pie smoothies with some extra to sprinkle on top.
