Blend pumpkin puree and ice cubes together until combined (see Step 1 image above).
Add milk and blend together (see Step 2 image above). Add brown sugar, Sweet'N Low, and ground cinnamon. Blend together until smooth (see Step 3 image above).
Pour into glasses and top each smoothie with a sprinkle of pumpkin pie spice (see Step 4 image above). Enjoy!
Notes
I also SPRINKLED a little pumpkin pie spice on top of each smoothie for added spice, but that’s totally optional!
