What I love about my overnight oats recipe is that it gets its sweetness from banana! Mashed banana makes these oats extra creamy and sweet, without having to add loads of maple syrup or other sweeteners. You only need just a touch of maple syrup since the banana does all the work.

This recipe feels so desserty yet it’s made with simple wholefood ingredients. It’s a breakfast that’s vegan, gluten-free, dairy-free and meal-prep friendly, and truly one that all eaters adore! I hope you love it as much as I do.

Ingredient Notes:

These chocolate overnight oats use simple, whole-food ingredients; which is what I love about this recipe! It’s always important that my recipes have ingredients that you likely already have in your kitche, or that are easy to find at your local grocery store if needed.

Here’s what you’ll need.

Banana: Mashed banana makes the oats rich and creamy, and adds natural sweetness. The riper the banana, the sweeter your oats will be!
Oats: I use old-fashioned rolled oats, which soak up the almond milk overnight for a soft, pudding-like texture. I also recipe tested this with quick oats, but the result was mushy.
Chia seeds: These little seeds thicken the oats as they soak, giving them that dreamy, spoonable consistency. Adding chia seeds to your overnight oats is a must in my opinion, because they really help to abosrb the liquid for the perfect consistency. You just don’t achieve that when using just oats.
Almond milk: Store bought almond milk works great for this recipe, it’s even better with homemade almond milk because it’s extra creamy – but that requires a little more time and effort. I also recipe tested this with oat milk and it was yummy.
Cocoa powder: Just a couple of teaspoons gives these oats a rich, chocolatey flavour.
Maple syrup: A little goes a long way since the banana and dates add so much sweetness. Feel free to add more to suit your taste.

How to make these Vegan Chocolate Overnight Oats

Making this recipe is so simple and straight forward. The exact details are in the recipe card, but here’s what you’ll do:

NIGHT BEFORE: Mash the banana in a bowl.
Stir in the oats, chia seeds, almond milk, cocoa powder, and maple syrup.
Refrigerate overnight.
NEXT MORNING: Stir the oats well.
Top with the chopped date, blueberries, pomegranate seeds, coconut shavings, and sunflower seeds.

Tips for the Best Overnight Oats

Prep the night before: Stir together the banana, oats, chia, almond milk, cocoa and maple syrup, then pop it in the fridge. If you’re using frozen blueberries, set them in the fridge to thaw at the same time.
Enjoy it warm or cold: For pudding-style oats, eat them straight out of the fridge. For a cozy porridge, warm them in a saucepan with a splash more almond milk until heated through and your desired thickness.
Add toppings last: Save the dates, blueberries and seeds for the morning so everything stays fresh and crunchy.
Make it a meal-prep breakfast: Mix up a few jars at once for easy grab-and-go breakfasts during the work-week.

So there we have it! Creamy, chocolatey overnight oats made with a few simple ingredients. I really think you’re going to love this chocolate banana overnight oats recipe as much as we do. It’s a breakfast worth waking up for!
