Why this smoothie works

  • Coffee-shop flavour with measured ingredients
  • Approximately 25g protein using the listed ingredients
  • Decaf works as a flavour substitution

  • 1frozen banana
  • 1 scoopvanilla whey or plant protein
  • 2 tbsprolled oats
  • 1/4 cupmilk of choice

The method

Let’s blend this.

Start with properly chilled coffee. Mix the powder into the liquid before the frozen banana creates the frothy finish.

0 / 4 done
  1. Chill the coffee

    Use cold brew or coffee that has been cooled and refrigerated. Break the frozen banana into small pieces and measure the remaining ingredients.

    Your cue: The coffee should be cold before it goes into a closed blender jug.

  2. Blend · about 15 sec

    Mix the coffee base

    Pour coffee and milk into the jug. Add oats and protein powder, secure the lid and blend on low for about 15 seconds.

    Your cue: Look for an even liquid with no dry protein pockets.

  3. Blend · about 45 sec

    Make it cold & creamy

    Stop and add banana, cinnamon and ice. Blend for about 45 seconds, starting low. If the mixture stops moving, switch off and add a splash of milk.

    Your cue: The banana and ice should be blended through; a light foam on top is normal.

  4. Let the foam settle

    Switch off and let the froth settle briefly before pouring. Taste and check for ice pieces with a spoon, then serve cold.

    Your cue: A foamy top is fine; large air pockets and ice chunks need a quick check.

The finish line

Here’s what you’re aiming for.

A cold, café-style smoothie with a light foam cap and a creamy banana base.

Too thick, thin or grainy?

Blending times are starting points; use the texture cues and your blender’s instructions. Loading order is for a typical upright jug. Switch off before scraping or tasting, and never put utensils into moving blades.

Pro tips

  • Freeze leftover coffee in an ice cube tray and use it in place of the ice for a stronger, colder smoothie.
  • One tablespoon of cacao turns this into a mocha.

Frequently asked questions

Yes. Dissolve 1.5 teaspoons of instant coffee in a quarter cup of hot water, cool it, and use more ice.
