Ingredients in this recipe on a white marble background.

Peanut butter — use a good quality natural peanut butter; smooth or crunchy both work well.

Raw cacao powder — minimally processed, it delivers a deep chocolate flavour. Unsweetened cocoa can be used as a substitute if needed.

Old fashioned rolled oats — these give the best texture. Other oat types work but may need different liquid ratios.

Milk — any milk will do. Almond, oat, soy or dairy milk all work depending on your preference.

Chia seeds — help thicken the mixture and add fibre. Use black or white chia as you prefer.

Maple syrup — adds a touch of sweetness. Honey can be used instead (consider drizzling it on top when serving).

Tips for success and FAQs:

These oats are a quick, reliable breakfast. Use a quality natural peanut butter for the best flavour. If the mixture is too thick in the morning, stir in a splash of extra milk.

How long do the overnight oats keep?

Store in the fridge and enjoy within three days for the best texture and flavour.

How long should the oats chill before eating?

Refrigerate for at least 6 hours. Overnight is ideal.

Are rolled oats gluten-free?

Some rolled oats are processed in facilities that handle gluten-containing grains. If you need gluten-free oats, choose products labelled gluten-free and check local guidance.

Variations and substitutions:

Banana: Mash a ripe banana into the mix for added sweetness and creaminess.

Milk: Swap for any plant or dairy milk you prefer.

Raw cacao powder: If unavailable, use unsweetened cocoa powder (you may want a little less).

Peanut butter: Try almond or cashew butter for a different nutty twist.

Serving suggestions:

Customise the toppings to suit your tastes. My favourites are coconut yoghurt, a peanut butter drizzle and cacao nibs for crunch.

Other topping ideas:

  • Chopped peanuts for extra texture
  • Greek yoghurt if not keeping the recipe vegan
  • Fresh or dried fruit for brightness
