  • Blender


  • 1 banana fresh or frozen
  • 1/4 cup oat flour
  • 1 1/14 cups coconut milk or oat milk
  • 1 Tablespoon maple syrup
  • 2 Tablespoons peanut butter or sunflower butter
  • 1/8 teaspoon vanilla extract


  • Add all liquid ingredients into your blender.
  • Add your banana and oat flour on top of the liquid ingredients. Adding the oat flour at the end will ensure that it doesn’t get stuck to the sides of the blender (or at least not as bad!)
  • Blend until completely smooth.
  • Pour into a large cup or mason jar and enjoy.
