Place the chopped pears, Greek yogurt, almond milk, honey, cinnamon, ginger, and nutmeg into the jar of a high-speed blender.
Add the ice cubes to the mixture.
Secure the blender lid firmly and process on the highest speed setting for 45 to 60 seconds until the texture is completely homogenous.
Stop the blender and check for consistency; pulse for an additional 10 seconds if necessary.
Pour the contents into chilled glasses and serve immediately, optionally garnished with a dusting of cinnamon.
