Put non-dairy milk, a big handful of kale, canned pumpkin, frozen banana chunks, flaxseed or chia seed, maple syrup, vanilla extract, ground cinnamon, and nutmeg into a blender. Blend until fully blended.
Add ice cubes to blender. Blend until the ice cubes are fully broken down.
Notes
Depending on the size of your bananas, you can use either 2 or 3 frozen bananas.Canned pumpkin is not the same as pumpkin pie filling. The ingredients should read 100% pumpkin.If your non-dairy milk is sweetened, you may want to omit the maple syrup.If you're not using a high speed blender, I recommend blending the kale alone with the non-dairy milk before adding the other ingredients. It helps to fully break down the kale. You'll also want to use ground flaxseed/chia seed, or grind it in a coffee grinder before putting it in the blender.
