Today I’ve got a new overnight oats recipe and these are the bomb! These brownie batter overnight oats are fudgy and rich but yet still healthy and make for an easy breakfast (or treat) on the go!

Overnight oats will forever be one of my favourite breakfasts, especially when I’m busy and need a quick thing to grab in the morning. These brownie batter overnight oats are perfect for busy days at work as well because I always crave sugar and treats on busy or annoying days. These oats help get rid of those cravings and keep me full so I’m not interested in eating anything else.

Brownies are one of my all time favourite desserts so I knew I had to create a brownie overnight oats recipe. These will not disappoint any chocolate or brownie lovers out there and will keep you fueled for long days.

For more overnight options, try my gingerbread cookie overnight oats, especially for a seasonal treat, my black forest overnight oats or my coconut cream pie overnight oats.

Yes, anything should work like almond butter or natural peanut butter but those may add flavour to the oats. Cashew butter is more neutral tasting.

  1. Super simple and quick to make. Only takes about 5 minutes.
  2. Easy to grab out of the fridge in the morning and take with me to work.
  3. Easy to eat when I’m busy at work. I can have a couple bites while I’m going over patient’s imaging at my desk and then come back to it later.
  4. Adding to the previous reason, when I take 3-4 hours to eat my oats throughout the morning, they taste good straight out of the fridge and once they’ve warmed up to room temperature. Perfect breakfast when you don’t actually get a proper break to eat. While some people may say I could eat before work, I don’t care to get up earlier in the morning and I’m never hungry until I’ve been up for 1-2 hours. I know many other people have the same problem.
  5. They are super healthy and easy to add various toppings too like berries for added nutrition.
  6. There are a million different flavour combinations. Believe me, I’ve got about 30 different recipes written down that I need to test. This is important to me because I find I get bored of foods quick. If I can eat a different flavour every day of the week, I’m likely not going to get bored. Plus you are then eating a variety of different foods.

  • Oats are a great source of fibre, mostly soluble fibre which helps slow down digestion and keeps you feeling full longer. The type of soluble fibre also aids gut health by supporting healthy gut bacteria. This can help reduce inflammation and symptoms of irritable bowel syndrome.
  • While many people say oats have no protein and aren’t a good thing to eat due to this, we seem to be a very protein obsessed culture currently, this isn’t actually true. While oats aren’t a high source of protein, they do contain about 4g per serving and include a good balance of essential amino acids. This is still important as you do need all of the essential amino acids in your diet, not just some of them.
  • Oats are also high in iron, an essential mineral that many people don’t get enough, especially women. Iron is essential for making hemoglobin which is how your body carries oxygen throughout your body.
  • As well as iron, oats are also a good source of other trace minerals like manganese, copper and phosphorus. These all aid your body in various tasks like bone building, collagen forming, creating red blood cells, etc. These are just a few of the benefits of eating oats and a few of the reasons I love them so much.

Making this recipe gluten free is super simple, all you need to do is ensure your oats are certified gluten free. That’s it!

As a side note, if making anything gluten free for someone with an allergy, ensure you thoroughly wash any equipment, jars or utensils. Any contact with flour may trigger an allergy. I like to say any baking I do in my own home is gluten friendly as I am using flour often and cannot guarantee there’s been no cross contamination.

  • If you find your cashew butter pretty stiff, scoop your tbsp into a microwave safe dish and pop it in the microwave for 10-20 seconds. This allows it to incorporate easier. I use a glass dish for my microwave oats so I just put it in the same dish.
  • For best results, once you’ve mixed everything together, let it rest in the fridge overnight for at least 6 hours. This helps the oats get nice and soft and gives you a creamier consistency.
  • I create my recipes based off weights so I recommend measuring by weights if you own a scale. It’s actually so much easier and makes for much less cleanup. I wish I had baked by weight from the beginning, I could never go back now.

Today’s song is one I listened to a lot while in university and I actually got to see them love, which was amazing! Here’s I And Love And You by The Avett Brothers. Happy baking! **Disclaimer: Liv’s Little Muffins owns no rights to this song.
