Let’s blend this.

0 / 4 done
  1. Rest · overnight, refrigerated

    Soak overnight

    Combine the oats and measured milk in a clean jar. Stir so no oats remain dry, cover and refrigerate overnight. Keep the yogurt refrigerated until you are ready to blend.

    Your cue: By morning the oats should be plump and softened, not dry in the centre.

  2. Add the breakfast ingredients

    Tip the soaked oats and all their milk into the blender. Add yogurt, peeled banana, peanut butter and cinnamon. Save the optional honey until after tasting.

    Your cue: Scrape all the soaked oats from the jar so the measured portion is included.

  3. Blend · about 45 sec

    Blend into a creamy breakfast

    Secure the lid, start low and blend for about 45 seconds. Stop and add a small splash of milk if it is too thick to circulate.

    Your cue: The banana should disappear into the base; fine oat texture is normal.

  4. Taste before sweetening

    Stop the machine and taste. Add the optional honey only if wanted, blend briefly and pour. Serve cold; this recipe's preparation includes the overnight soak as well as the morning blending.

    Your cue: Aim for a thick but pourable drink, or enjoy a thicker version with a spoon.

The finish line

Here’s what you’re aiming for.

A mellow, thick breakfast smoothie with softened oats and a cinnamon finish.

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

  • Batch 5 jars of oats and milk on Sunday for the whole week.

Frequently asked questions

Yes, but let them sit in the milk for 5 minutes before blending to avoid a gritty texture.
