There’s no better way to start the morning than with chocolate overnight oats with peanut butter. It’s basically like indulging in rich fudgy goodness in a jar. Think… chocolate and peanut butter infused into oatmeal with a sweet hint of banana, and topped up with ALL THE THINGS. 

The best part is you can make it the night before, divide the mixture into jars and stick it in the fridge overnight. 

Wake up in the morning and a mouthwatering breakfast is there waiting for you in fridge! If you make up a double or triple batch, you’ll have a whole bunch of decadent breakfasts ready to go for the week. How sweet is that?!

Why Make this Recipe

Easy – These overnight oats take less than 10 minutes to prep. Breakfast doesn’t get much easier than that!

Healthy – Oats and chia seeds provide a dose of soluble fibre which can leave you feeling full for hours, while also helping to balance blood sugar levels. The cocoa powder incorporates antioxidants, while the peanut butter offers some protein and healthy fats. The banana offers potassium and additional fibre, while adding natural sweetness, so no added sugar is required. 

Totally crave worthy – It’s hard to go wrong with any breakfast that involves chocolate and peanut butter. This is one breakfast that we never get tired of!

Make-ahead – Overnight oats are perfect for crazy busy mornings where you need a breakfast that you can just grab and go. Make up a large batch and you’ll have breakfast for the week!

Ingredient Notes

Oats – For overnight oats, I generally like to use rolled or large flake oats since they lend a chewier consistency and tend to be less processed. That being said, quick oats work well too, so you can use whatever you have on hand.

Chia seeds – Help to thicken the overnight oats while adding some additional fibre to make the oats super filling. You can use black or white chia seeds; there is no nutritional difference.

Cocoa powder – The cocoa powder adds a rich chocolate flavour to these oats and provides a dose of antioxidants. If possible, use cacao powder rather than Dutch processed cocoa or baking cocoa powder for best results since it lends a richer and bolder flavour and offers more antioxidants.

Almond milk – The milk is absorbed by the oats and chia seeds to form a thick and creamy oat mixture. Use unsweetened almond milk to limit added sugar. You can also sub in regular milk or another plant-based milk alternative if preferred.

Peanut Butter – Provides a nutty flavour and incorporates some protein and healthy fats. I used natural peanut butter, which contains just “peanuts” on the ingredients list. Use a creamy or sub in crunchy if you want some peanut chunks integrated into the oatmeal mixture. Feel free to sub in almond butter or another nut or seed butter, if preferred. 

Banana – Adds a natural sweetness to the overnight oats. Use an overripe banana for maximum sweetness. 

Step by Step Instructions

Step 1 – Divide the oats, cocoa powder, chia seeds and salt between two mason jars or bowls. Give it a quick stir to combine. 

Step 2 – Next divide the almond milk, peanut butter, banana, and vanilla between the jars and stir thoroughly to combine, making sure that the peanut butter and banana are distributed evenly.

Step 3 – Cover the containers and allow the oats to sit in the fridge overnight or until thickened (sometimes I’ll even just leave them for 30 minutes to an hour and they’re all ready to go)! Taste. Add in maple syrup or preferred sweetener and/or protein powder, if desired.

Step 4 – To serve, top with a drizzle of peanut butter, chocolate chips and chopped peanuts, if desired.

Recipe Tips

• Use an overripe banana as this will help contribute extra sweetness to the oat mixture. Bananas that aren’t ripe don’t tend to be as sweet and have a stronger banana flavour.
• Make sure that you thoroughly mix in the peanut butter and banana so that the flavours are distributed evenly throughout the oat mixture.
• Be sure to mix the oat mixture well, folding it with a spoon or small spatula, as sometimes the cocoa powder or other ingredients may settle to the bottom of the bowl or jar.
• Sweeten the overnight oats to taste. Personally, I skip the maple syrup and just add a tablespoon of vegan vanilla protein powder and find that adds the perfect amount of sweetness and a little extra protein!
• The oats can be eaten cold, at room temperature or warm. If you would like to eat them warm, heat them in the microwave for 30-60 seconds.

Recipe FAQ

Storage guidelines

The overnight oats can be stored in the fridge covered for up to four days.

Can I use a frozen banana?

Yes, it’s a great way to put those frozen bananas to good use! Just make sure that you thaw the banana and mash it well before mixing it into the oat mixture to ensure it’s evenly distributed.

How to make these overnight oats higher in protein

To add an extra dose of protein, you can either add some protein powder (I like to use vanilla to add some extra flavour, but you can use unflavoured as well), Greek yogurt or pasteurized egg whites. If you choose to use the egg whites, you may need to cut back a bit on the milk since it will add some extra liquid to the oats.

If you add Greek yogurt or protein powder, you may need to add some extra milk depending on how much you choose to use.

Serving suggestions

You can serve overnight oats cold, at room temperature or warm. In the summer, I tend to like to eat them cold, but in the winter, I’ll often warm them up in the microwave for 30-60 seconds. It’s totally a personal preference how you choose to serve them up.

That being said, I highly recommend serving them with the following toppings:

• Dark chocolate chips
• Drizzle of peanut butter
• Sliced bananas
• Chopped peanuts
