Peanut Butter Banana Smoothie

A peanut butter banana smoothie sits somewhere between a quick breakfast drink and a satisfying snack: thick, cold, creamy and naturally sweet from ripe banana. The combination of whole milk, Greek yoghurt and smooth peanut butter gives it more body than a fruit-only smoothie, with a mellow nuttiness that makes it feel filling without becoming heavy. Honey can round out the sweetness, while vanilla and cinnamon add warmth if you want a more dessert-like flavour. Best poured and served straight after blending, it is also easy to loosen with a splash more milk if you prefer a thinner, more drinkable texture.

Why this recipe works

  • Ready in minutes: Everything goes straight into the blender, so the smoothie comes together quickly with very little prep.
  • Naturally thick and creamy: Ripe banana, Greek yoghurt and peanut butter create body without needing ice cream or added thickeners.
  • Sweet but not cloying: Honey adds gentle sweetness while yoghurt keeps the drink balanced and slightly tangy.

Texture tips

  • For a thicker smoothie: Use chilled yoghurt and milk, and choose a very ripe banana for the smoothest, fullest texture.
  • For a looser drink: Blend in a splash more milk until the smoothie pours easily.
  • Blend until fully emulsified: Pause to scrape down the blender if peanut butter sticks to the sides, then blend again until completely smooth.

Ingredient notes

  • Use a ripe banana: A well-ripened banana brings more natural sweetness and a creamier blend.
  • Milk affects richness: Whole milk gives a fuller texture, while oat drink makes a lighter dairy-free version.
  • Adjust the honey: Taste before adding extra honey, especially if the banana is already very sweet.

Dietary alternatives

  • Dairy-free option: Use oat drink instead of whole milk and choose a dairy-free yoghurt alternative if needed.
  • Vegan option: Swap the honey for agave syrup and use plant-based milk and yoghurt.

Make-ahead tips

  • Best freshly blended: The smoothie has its best texture immediately after blending.
  • Short storage only: If needed, refrigerate in a sealed container for up to 1 day, then shake or re-blend before serving.
