Ingredients
  

  • 1 large frozen banana, sliced (about 1 cup)
  • 2 tablespoons natural peanut butter (or powdered peanut butter for lower fat)
  • 1 scoop vanilla or unflavored protein powder (whey, pea, or your favorite)
  • 1 cup milk (dairy or unsweetened almond, soy, or oat milk)
  • 1/2 cup Greek yogurt (plain or vanilla; optional but adds creaminess and protein)
  • 1–2 teaspoons honey or maple syrup (optional, to taste)
  • 1/2 teaspoon vanilla extract (optional)
  • Pinch of cinnamon and a tiny pinch of salt (optional, but elevates flavor)
  • 4–6 ice cubes (optional, for extra thickness if your banana isn’t very frozen)

Method
 

  1. Prep your banana: For the best texture, peel and slice ripe bananas, then freeze them in a bag. A fully frozen banana is key for that thick, creamy blend.
  2. Add liquids first: Pour the milk into your blender. Liquids at the bottom help everything blend smoothly without overworking the motor.
  3. Layer in the rest: Add the frozen banana, peanut butter, protein powder, and Greek yogurt. Sprinkle in cinnamon, a tiny pinch of salt, and vanilla, if using.
  4. Sweeten to taste: If your banana is very ripe, you may not need extra sweetener. Add honey or maple syrup only if you prefer a sweeter smoothie.
  5. Blend until silky: Start on low, then increase to high for 30–45 seconds, until completely smooth. If the mixture is too thick, add a splash more milk. If it’s too thin, add a few ice cubes and blend again.
  6. Serve cold: Pour into a chilled glass. For a finishing touch, top with a sprinkle of cinnamon or a few crushed peanuts.
