Happy weekend! I just got back from my 18 km run, and I must admit that it was a real struggle today. We’re in the midst of a heat wave, and even when I finished at 9:45, it felt like 32 degrees Celsius with the humidity. It was definitely an exercise in character building! We’re having my brother, sister in law, and niece over for dinner tonight; we hit up the farmer’s market this morning to buy some ingredients and are making salmon burgers, corn on the cob, and kale slaw salad for dinner… and ice cream, hot fudge sauce, and local strawberries for dessert. Should be so good; I love our weekend family dinners!

Speaking of heat waves, these Greek yogurt banana overnight oats have been my saving grace throughout this hot summer. There’s nothing better than waking up and having a cold, creamy bowl of oats ready and waiting in the fridge!

everything you need to know about overnight oats

For those unfamiliar with overnight oats, they are a no-cook version of porridge that you mix up in the evening. You refrigerate them overnight. As they sit in the fridge, they soften and thicken up thanks to the chia seeds. Come morning, they are ready to enjoy with all of your favourite toppings!

what makes greek yogurt overnight oats better?

There are many popular vegan overnight oats recipes on the internet. I have tried and enjoyed many of them, but I have finally come up with my favourite formula using half creamy, protein-rich Greek yogurt and half non-dairy milk.

The Greek yogurt makes my overnight oats recipe rich, creamy, and satisfying. It also adds a whopping 10 grams of additional protein to your morning oatmeal. Not bad at all!

the formula for the best overnight oats

I have found the formula for the best overnight oats that are neither too thick nor too thin and perfectly sweet to be:

½ cup Greek yogurt
½ cup non-dairy milk
½ cup rolled oats
1 tablespoon chia seeds
½ tablespoon-1 tablespoon sweetener (depending on whether you are adding fruit or not)

ingredients in greek yogurt banana overnight oats

Banana: You’ll need half of a banana for this recipe. For best flavour, use a ripe banana that is just becoming speckled. Avoid using an overripe banana, or the flavour will become overpowering. The banana helps sweeten these overnight oats, along with a bit of honey.
Rolled oats: I use regular large flake rolled oats. Don’t use steel-cut oats, as they don’t work in overnight oats. You can use quick-cooking oats, if you wish!
Chia seeds: Chia seeds help to thicken the overnight oats, as well as adding some omega-3 fats and a bit of calcium and fibre. No chia? Try a tablespoon of ground flax seed instead.
Honey: I find that half a tablespoon of honey adds the perfect amount of sweetness to this recipe. Add more or less to your taste. No honey? Try maple syrup, coconut sugar, or brown sugar.
Sea salt: I always add a small pinch of fine sea salt to my sweet recipes. Salt helps to bring out the flavours of all ingredients, while also providing your body with some much-needed sodium, an electrolyte that is incredibly beneficial for your health. Particularly if you are an athlete who sweats, you absolutely need to be adding salt to your meals. Unrefined sea salt also provides a variety of trace minerals.
Greek yogurt: Greek yogurt is thick, creamy, and rich in protein and calcium. You are going to want to use unflavoured, unsweetened Greek yogurt in these oats. No Greek yogurt? Regular plain yogurt will also work. Your oats just might not come out as thick and creamy.
Non-dairy milk: Again, you will want to use unsweetened, unflavoured non-dairy milk. You may use dairy milk, if you wish. Your overnight oats will just be extra creamy, delicious, and nutrient-rich!

how to make the best creamy banana overnight oats

Mash the ½ a banana in a medium bowl. Add the remaining ingredients and mix well to combine. Transfer into an airtight jar or container. Refrigerate overnight.

In the morning, check and see how thick the oats are. I like to add a splash of non-dairy milk to thin out slightly.

Transfer into a bowl and add your favourite toppings. Here are some of my favourite overnight oats toppings:

the best toppings for overnight oats

Berries
Granola
Nut butter
Hemp hearts

But if you want a real treat (that tastes indulgent but is actually very nutritious), you must make this chocolate almond butter topping. Keep it in the fridge and use it as a topping for everything from these overnight oats to ice cream. Or as a fruit fondue dip. It is divine!

Chocolate Almond Butter Topping:

½ cup almond butter
¼ cup cacao powder
¼ cup maple syrup
6 tablespoons unsweetened non-dairy milk
Pinch of sea salt

Mix together all ingredients in a small saucepan and gently warm over low heat, whisking often. The heat simply helps to melt the almond butter slightly, which helps with mixing. Once smooth, remove from the heat. Once cool, transfer into an airtight container and store in the refrigerator.
