My version of Polyjuice Potion takes form in a tasty smoothie, which includes a creamy base of thick Greek yogurt, whole milk, and banana as well as blueberries and spinach to give it a muddy potion-like appearance. Unlike the Polyjuice Potion in the books, which takes roughly a month to make, this Polyjuice Potion Smoothie takes 5-minutes or less to create and requires no hair or toenail clippings -- In fact, I strongly discourage adding those things!


  • 106 g (about 1 small) frozen sliced banana
  • 75 g (about 1/2 cup) frozen blueberries
  • 25 g (about 1/4 cup) frozen spinach
  • 60 g (about 1/4 cup) thick Greek yogurt, plain or vanilla
  • 120 g / 4 oz (about 1/2 cup) whole milk (can adjust to preference or may swap for water)
  • Optional: a scoop of unflavored protein powder like Vital Proteins


  1. Add all ingredients to your blender. Blend until smooth, adjusting the amount of milk you use if you prefer a thinner smoothie.
