Why you’ll love this recipe:

A much-loved flavour combination that makes a delicious breakfast, you will love these Chocolate Peanut Butter Overnight Oats!

You’ll love how easy they are to prepare – they’re perfect for those mornings you’re short on time or need breakfast on the go. These oats are nutritious and will keep you full for longer.

You will love these Chocolate Peanut Butter Overnight Oats because:

  • This recipe is so versatile – customise the flavour and toppings to your liking. Although delicious as is, I sometimes like to add a mashed banana to the mix. Top with nuts, yoghurt, cacao nibs, a drizzle of peanut butter… or, all of the above!
  • They require minimal preparation – all you have to do is combine your peanut butter, cacao and liquids, then add in your other ingredients and pop it in the refrigerator!
  • The quantities can easily be adjusted to your needs – the written recipe serves two, but can easily be halved or doubled!
  • They are ideal for meal prep – they’ll last for three days in the fridge, so you can get a head start on your breakfast for the week ahead.
  • Peanut butter and chocolate are an ideal match, similar to Peanut Butter and Banana.

Ingredients in this recipe:

Please see the recipe card further along in the post for exact quantities of ingredients and the full method.

Ingredients in this recipe on a white marble background.

Peanut Butter – use good quality natural peanut butter. Smooth or crunchy both work fine in this recipe.

Raw cacao powder – is made from minimally processed cocoa beans and maintains the nutritional benefits of the bean. In essence, it is chocolate in its purest form. 

Old Fashioned Rolled Oats – are the best oats for this recipe. Steel-cut oats and quick-cooking oats can be used in overnight oats recipes, but may have a different ratio of liquid, and will produce a different texture.

Milk – use any milk of your preference. I like to use almond or oat milk, but soy milk works just fine as does dairy milk if you do not require the recipe to be vegan.

Chia seeds – helps to give the oats a nice thick texture, and also add some extra fibre. Black or white chia seeds are fine to use in this recipe.

Maple syrup – for a hint of sweetness. You could also use honey, but I would drizzle this on top when serving instead.

How to Make Chocolate Peanut Butter Overnight Oats:

Please see the recipe card further along in the post for exact quantities of ingredients and the full method.

Steps 1-2 of preparing this recipe - the cacao, peanut butter and milk in a bowl and the mixture combined.

1 – Add the liquids and cacao to a bowl:
In a medium bowl, add the peanut butter, maple syrup, raw cacao powder and milk.

2 – Mix the liquids:
Whisk well to combine, ensuring there are no lumps.

Steps 3-4 of preparing this recipe - adding the oats and chia to the wet ingredients and the mixture combined ready to go in the fridge.

3 – Add the remaining ingredients:
To the chocolate mixture, add your rolled oats and chia seeds. Whisk or stir the mixture well to combine.

4 – Refrigerate:
Cover the bowl with clingwrap, or divide the mixture into two glasses or mason jars and cover. Refrigerate for 6 hours or overnight.

Tips for success and FAQs:

These Chocolate Peanut Butter Overnight Oats are one of my favourite easy breakfasts to prepare. Ensure you use good quality natural peanut butter for the best flavour.

How long will the Chocolate Peanut Butter Overnight Oats last?

Enjoy the oats within three days, for the best taste and texture.

How long do the Oats have to be in the fridge before consumption?

Refrigerate your overnight oats mixture for at least 6 hours. I make mine just before bed and they’re perfect in the morning!

Are Old Fashioned Rolled Oats Gluten-Free?

There are different rules regarding this, depending on where you live in the world. For Australian residents, Coeliac Australia provides a great resource on this topic. Always be sure to read the labels and consult with a health professional if you are unsure.

Variations and substitutions:

Banana – absolutely optional, but a delicious variation is to add a mashed banana to the Chocolate Peanut Butter Overnight Oats.

Milk – you can use any milk of your choice for this recipe.

Raw Cacao Powder – if you are unable to find it, you can substitute it with unsweetened cocoa powder. You may wish to use a little less, as it does have a stronger taste.

Peanut Butter – almond or cashew butter can be substituted.

Serving suggestions:

One of the best parts about making your own Overnight Oats is being able to customise the toppings to your liking.

For this recipe, I like to use a topping of coconut yoghurt, a drizzle of peanut butter and a sprinkle of cacao nibs for texture.

You could also try:

  • Chopped peanuts.
  • Greek yoghurt, if you do not need to keep the recipe vegan.
  • Fresh or dried fruit of your choice.

I hope you enjoy these delicious Chocolate Peanut Butter Overnight Oats. I hope you’ll love the ease of preparation and great taste – be sure to let me know what you think in the comments below!

Please note:

For accuracy, when weights are provided, we recommend weighing your ingredients. This will produce the best results. All oven temperatures listed are for fan forced.

Ingredients

For the Overnight Oats:

  • ¼ cup peanut butter See Note 1
  • 1 tablespoon raw cacao powder See Notes 2 and 3
  • 2 tablespoon maple syrup
  • 1 ¼ cup (300 ml) milk – I use almond or oat See Note 4
  • 1 cup (80 g) old fashioned rolled oats
  • 1 tablespoon chia seeds

Toppings (optional):

  • Greek yoghurt or coconut yoghurt
  • peanuts – roughly chopped
  • peanut butter drizzle and cacao nibs

Instructions

  • In a medium-size bowl, add the cacao powder, maple syrup, peanut butter and milk. Whisk until well combined, ensuring there are no lumps.
  • Add the oats and chia seeds and stir to combine.
  • Cover the bowl with clingwrap, or divide the mixture into two glasses or mason jars and cover. Refrigerate for 6 hours or overnight.
  • Serve with toppings of your choice and additional milk if the mixture is too thick.

Notes

  1. Peanut Butter: use smooth or crunchy – whatever you prefer.
  2. Raw Cacao Powder: is the raw version of cocoa powder. 
  3. Tablespoon: we use a standard Australian tablespoon which is 20 ml (4 teaspoons).
  4. Milk: use milk of your choice. I use almond or oat milk. Add more milk when serving if you prefer a thinner texture.
  5. Toppings: the toppings are optional (and are not included in the nutritional information). Use toppings of your liking – see suggestions above.

    I haven’t tried this recipe yet. Does it have to have the raw cacao powder or can I just use dark chocolate cocoa powder? Real quick oats work just as well as old fashion oats?

      Hi Holly,
      Cocoa powder will work fine – I just recommend unsweetened. I do recommend old-fashioned oats for overnight oats as they produce the best texture. Quick oats will produce a softer texture and can be a little mushy to my taste, but if you don’t mind that, they should work fine.
      Let me know if you give the recipe a try! Thanks, Alex

    This is hands down my new fave overnight oats recipe! I love that it uses raw Cacao as I have been trying to incorporate more into my diet. Really well balanced flavor- tastes like a treat but not too sweet. I look forward to making this each time and am so glad I found it! Can’t wait to try more from the site!
