Ingredients needed

You probably already have everything needed to make this peanut butter banana smoothie recipe! Here’s the lineup:

  • Bananas: For best results, use frozen ripe bananas to ensure the smoothie is cold, thick, and has a natural sweetness.
  • Milk: We usually use unsweetened vanilla almond milk, but feel free to use any milk that you like.
  • Peanut butter: Creamy peanut butter adds tons of delicious flavor. To keep this recipe clean, use natural peanut butter. Alternatively, almond butter or another nut (or seed) butter may be substituted.
  • Sweetener: You can make this smoothie sweeter by adding honey or agave.
  • Oats: This will bulk up the smoothie and make it super thick.

How to make this recipe

  1. Blend ingredients: In a high-powered blender, place the frozen bananas, milk, peanut butter, honey, and oats. Blend until smooth.
  1. Check for consistency: If it is too thick to your liking, add another ¼ cup of milk and blend again.
  2. Enjoy: Serve in cups, and top with sliced banana and peanut butter drizzle. Other optional toppings: chocolate chips or roasted peanuts.

Expert Tips

  • Use a high-powered blender. To make a super creamy, well-blended smoothie or protein shake it’s best to use a high-powered blender (Blendtec, Vitamix, or Ninja all work great) to break down all of the ingredients.
  • Adjust the consistency. Use more or less milk to make this thinner or thicker.
  • Do not use ice. Using ice will dilute the smoothie and can make it too icy, not creamy. Using the frozen banana will make it plenty creamy.
