Mix avocado, pumpkin, and stevia in a food processor or blender until smooth.
Add remaining ingredients and process until smooth.
Serve, and enjoy!
Notes
A note about substitutions: You can replace the whey with casein or your favorite vegan protein (I think pea or a pea blend would be smoothest). You can replace the toffee stevia with your preferred sweetener. And cashew butter can be made by processing cashews in a food processor.
