Chocolate brownies for breakfast? Yes please! I’m talking about a healthy chocolate brownie treat though. This Banana Brownie Overnight Oats recipe is the perfect way to your day! It’s loaded with flavor and is the ideal breakfast to fuel you while you’re on-the-go.
Banana Brownie Overnight Oats Ingredients
- Organic Gluten-Free Rolled Oats: Rolled oats, also known as old fashioned oats, are the best kind of oats to use for overnight oats, because they absorb the liquid the best. However, if you only have quick oats on hand, you can use them too!
- Organic Banana: Adding half of a ripe banana to the recipe makes this breakfast sweet. Also, the riper the banana, the sweeter your breakfast will be.
- Organic Cacao Powder: To make the oats chocolatey! To be clear, cacao powder is different from regular dutch cocoa powder. Cacao powder is pure, raw cacao versus processed. Plus, cacao is rich in magnesium.
- Organic Ground Flax Seeds: Loaded with nutrients, high in omega-3 fats, rich in dietary fiber, and you can’t even taste them. They are completely optional, so no problem if you don’t have them…yet!
- Organic Pure Maple Syrup: Just a little to sweeten the oats and to balance the flavor from the cacao powder. You can also sub the maple syrup for coconut sugar.
- Organic Pure Vanilla Extract: For a little extra flavor.
- Non-dairy yogurt: Non-dairy yogurt is not necessary, but it makes it this overnight oats recipe super thick and creamy.
- Organic Unsweetened Non-Dairy Milk: Any non-dairy milk will work to mix the oats up.

How to Make Overnight Oats
Overnight oats are probably the easiest and quickest breakfast to make. Plus, they taste so good.
First, in a medium sized bowl, mash the banana. Add the non-dairy milk, non-dairy yogurt, pure maple syrup, vanilla extract, cacao powder, and ground flax seeds. Mix well until you achieve chocolate banana milk.

Next, mix the oats and chocolate banana milk together in the mixing bowl.


Transfer to a jar or cover, place in the fridge overnight, and the oats will be ready to eat in the morning!
Tips for making the perfect overnight oats
To make the perfect overnight oats, make sure to follow these steps!
- Use organic gluten-free rolled oats for a chewy texture or quick oats for a softer texture.
- Be sure your banana is ripe. The more ripe your banana is, the sweeter your overnight oats will be.
- Begin by mashing your banana in a bowl first, before adding other ingredients.
- For preparation, mix this recipe in large bowl, because it’s easier to stir.
Overnight Oats FAQ’s
Are Overnight Oats Healthy?
Overnight oats are a wonderful breakfast option! They’re loaded with fiber and give you lasting energy throughout the morning. The addition of healthy fats, carbs, & protein in this recipe also provide some extra nutrients and essential minerals for you.
How Long Do Overnight Oats Last?
Typically, overnight oats last for 4-5 days in the fridge, however they’re best to be enjoyed within a couple of days, since the oats will become softer in texture.
Do You Eat Overnight Oats Hot or Cold?
However you want! Overnight oats are typically enjoyed cold. However, if you’re not a fan of cold breakfasts, then just pop them into the microwave or add them to the stove to heat them up, after they soak overnight.

Overnight Oats Toppings
The options are limitless when it comes to topping your overnight oats recipe. I personally topped my Banana Brownie Overnight oats with banana slices, dairy-free dark chocolate chips, cacao nibs, and a drizzle of peanut butter, but you can top your Banana Brownie Overnight Oats with whatever suits you!
