Place pumpkin, blueberries, pepitas, coconut, cashew butter, agave nectar, and pumpkin pie spice into a blender, preferably a high-speed blender. Pour in almond milk and add ice cubes. Process on low for 20-30 seconds then gradually increase speed to highest level. Blend for 30 seconds to 1 minute, or until completely smooth.
Serve cold. If only half is being consumed at this time, store the other half in a resealable jar in the fridge until ready to drink, up to 24 hours. Shake well before using.
