What are Overnight Oats?
Overnight Oats are basically a no-cook method of making oatmeal, by soaking old-fashioned rolled oats in milk in the refrigerator overnight. Instead of softening oats by cooking them, this slow method of allowing them to absorb the liquid create a beautifully creamy, luxurious, soft and thick texture. Meal prep is super easy with overnight oats - they're ready for you in the fridge as soon as you wake up, making them a huge time-saver for those busy weekday mornings when you're rushing off for school or for work.
The beauty of overnight oats is how easy and quick they are to make, with just a few simple ingredients. Not only that, but they are easily customizable with all of your favourite toppings and ingredients - giving you creative flexibility to experiment with your own unique flavour combinations, like this chocolate peanut butter cup flavour!
Ingredients
Please scroll down to the recipe card below for exact quantities and measurements.

- Rolled oats - make sure to use old-fashioned rolled oats, not steel cut, quick or instant oats as they don't absorb liquid well enough for this recipe.
- Unsweetened almond milk - any type of milk will work, whether it's regular cow's milk or a plant-based milk (ie. cashew or oat).
- Greek yogurt - I prefer Greek yogurt but you can use whatever type of yogurt you prefer. This helps adds an even thicker, creamier texture to the overnight oats.
- Chia seeds - packed with nutrition, chia seeds are a superfood that adds thickness to the oats mixture when they expand in liquid.
- Maple syrup - or you can use any type of sweetener you like. Honey also works very well in this recipe!
- Cocoa powder - I use unsweetened cocoa powder for a rich, chocolatey taste.
- Natural peanut butter - any type of nut or seed butter will work; just make sure to use one with a runny, drippy consistency for easy mixing.
- Pinch of salt - to help bring out the flavours.
- Coconut oil - to use as part of the mixture for the chocolate syrup topping.
- Berries (optional) - to use as a topping, adds some fruity balance to the chocolate peanut butter taste.
Instructions

STEP 1: First, prepare the overnight oats mixture: In a mason jar, mix together oats, milk, yogurt, chia seeds, maple syrup, cocoa powder, peanut butter, and a pinch of salt.

STEP 2: Once the ingredients have been thoroughly mixed, set the mixture aside while we prepare our chocolate syrup.

STEP 3: Prepare the chocolate syrup topping: in a small bowl, mix together melted coconut oil (1 tbsp), cocoa powder (1 tsp), maple syrup (1 tsp), and a pinch of salt.

STEP 4: Pour the chocolate syrup on top of the overnight oats mixture. Snap on a lid, and refrigerate overnight (or for at least 2-3 hours).

STEP 5: When it's ready, take it out of the fridge. The chocolate syrup will have hardened into a hard shell on top of the overnight oats. You can crack into it with a spoon and enjoy it with the oats. Enjoy!

How to Store
You can store these away in an air-tight container in the fridge for up to 5 days. I recommend using a 16-ounce (473 ml) wide mouth mason jar - they're super easy to clean and tall enough to stir ingredients in without creating a mess (and have enough height for space to add toppings to).
Toasty's Tips
- If you find your overnight oats to be too thick, just add a splash of milk to help thin it out until you reach the desired consistency. This is particularly important if adding extra protein powder or other nutritional powders to your mixture.
- Make sure to use nut (or seed) butter that has a runny, drippy consistency to make it easier to mix with. If your nut/seed butter has become too firm and difficult to stir, you can try warming it up in the microwave to soften it up.
- Customize it! Instead of berries, you can add in nuts, seeds, coconut flakes, whatever you like.
- Make it vegan or gluten-free by using plant-based milk, gluten-free oats, and other ingredients that fit in with your dietary needs.
FAQ
Do I have to make the chocolate shell?
No, it's totally up to you! The overnight oats will taste just as great on their own without the added step of making the chocolate shell.
Can I use chocolate protein powder instead of cocoa powder?
Yes, you can certainly swap the chocolate protein powder for cocoa powder - it's a great way to add a protein boost to your breakfast. If your protein powder is sweetened, you may want to reduce the amount of added sweetener (honey, maple syrup, etc) that you use so that you don't over-sweeten this recipe.
Can I warm these up before eating?
Technically yes, you can warm up overnight oats before eating them (although they typically meant to be enjoyed chilled straight out of the fridge). However for this recipe, due to the hardened chocolate shell, I wouldn't recommend heating it up first as that will very quickly melt the hard shell.
Can I eat this as a dessert?
Of course! Do what makes you happy.
