Chocolate Banana Smoothie

Part smoothie and part chilled chocolate shake, this drink blends ripe banana with cold whole milk for a naturally thick, creamy base. Unsweetened cocoa gives it a deeper chocolate flavour than syrup alone, while smooth peanut butter adds body and a gentle nutty richness. Maple syrup rounds out the sweetness, with vanilla and a pinch of salt helping the chocolate taste fuller. Best served straight from the blender while cold and glossy, it works as a quick breakfast, afternoon drink or simple dessert-style smoothie.

Why this recipe works

  • Ready in minutes: Everything is blended at once, making this a fast drink with very little preparation or cleanup.
  • Milkshake-like body: Ripe banana, cold whole milk and peanut butter create a smooth, thick texture without needing cream.
  • Balanced sweetness: Unsweetened cocoa keeps the chocolate flavour deep, while banana and maple syrup add just enough sweetness.

Ingredient notes

  • Use a ripe banana: A very ripe banana gives the smoothie better sweetness, a fuller texture and a more rounded flavour.
  • Choose the milk by texture: Whole milk makes the smoothie richer and creamier; almond drink gives a lighter, dairy-free result.
  • Taste before serving: Blend first, then adjust the sweetness if needed, as banana ripeness can change the final flavour.

Texture tips

  • For a thicker smoothie: Keep the milk well chilled and blend with ice for a colder, more milkshake-like finish.
  • For a smoother blend: If cocoa powder or peanut butter sticks to the blender, pause, scrape down the sides and blend again until glossy.
  • If it is too thick: Add a little more milk and blend briefly until the texture is easy to drink.

Make-ahead tips

  • Best served immediately: The texture is at its smoothest and coldest straight from the blender.
  • If storing briefly: Refrigerate in a sealed container and shake or re-blend before drinking, as it will separate and thicken.
  • Prep ahead instead: Keep the milk chilled and have the dry ingredients ready, then blend just before serving for the best texture.

Recipe notes

Tips

  • For the thickest, most milkshake-like texture, use a very ripe banana and keep the whole milk well chilled.
  • If the cocoa powder clings to the sides of the blender, stop and scrape down, then blend again until fully incorporated.

Substitutions

  • Replace Whole milk with Almond drink for a dairy-free version.
  • Replace Maple syrup with Honey for a slightly richer sweetness.
  • Replace Smooth peanut butter with Cashew nuts for a milder, less peanut-forward flavour.

Storage

  • Best served immediately. If you must store it, refrigerate in a sealed container and re-blend (or shake very well) before drinking, as it will separate and thicken.
