Ingredients
 

  • 2 Frozen Bananas
  • 2 tablespoons Peanut Butter
  • 2 tablespoons Old-Fashioned Oats
  • ½ tablespoon Ground Flaxseed
  • ½ teaspoon Cinnamon
  • Pinch of Kosher Salt
  • 1 cup Oat Milk
  • 3-4 Frozen Coconut Milk Ice Cubes see above

Instructions

  • Freeze the ripe bananas and coconut milk overnight or for at least 3 hours.
  • Peel the bananas and freeze them in a freezer-safe container until frozen.
  • Coconut Milk Ice Cubes: Whisk or shake the can of coconut milk until it's well combined. Pour the coconut milk into an ice cube tray and freeze until frozen.
  • Add all ingredients to a high-speed blender and blend until smooth and creamy. To thin out the smoothie, add more oat milk. To make it thicker, add a bit more frozen banana or another ice cube.
  • If your bananas weren't ripe enough, you may need to add a bit of sweetness. I recommend 1 tablespoon of maple syrup or 1-2 pitted dates.
  • Pour into a glass and enjoy!

Notes

This recipe makes 1 large serving or 2 small servings. Leftovers can be stored in an airtight glass jar in the fridge- it's best served as soon as possible but can be enjoyed up to 24 hours after blending.
