Add pumpkin puree, frozen banana slices, Greek yogurt, milk, maple syrup, pumpkin pie spice, vanilla extract, and salt to a high-speed blender.
Blend on high until completely smooth and creamy, about 1-2 minutes. If the mixture is too thin, add ice cubes and blend again.
The consistency should be thick like soft-serve ice cream, not pourable. Add more frozen banana if needed.
Divide the smoothie between two bowls, spreading it evenly with the back of a spoon.
Arrange your favorite toppings on top in sections or rows for that Instagram-worthy look.
Serve immediately with a spoon and enjoy your healthy fall breakfast!
