Matcha overnight oatmeal is a comforting, antioxidant-rich breakfast that can be prepped ahead of time and enjoyed hot or cold. The fresh, grassy matcha flavor is balanced by the slight bitterness of the tahini, a touch of sweetness from the maple syrup, and the rich depth of dark chocolate.

By now, you know I love oats. I include them in almost every dessert I make (sorry not sorry), but their "traditional" form also has a place in my heart. I'm talking about versatile, satisfying, nourishing OATMEAL!
There's the delicious mango-topped overnight oats, and I love this version of overnight oats with powdered peanut butter.
This overnight version of matcha oatmeal I'm sharing today is another winner. If you're looking for an overnight oats recipe without bananas, this is an excellent choice.
Oh, and if you love the matcha green tea flavor, you should also make a batch of these vegan matcha cookies while you're in the kitchen. 🙂

Recipe Highlights
- This overnight matcha oatmeal recipe comes together super fast and has only 8 ingredients (and no bananas!).
- The sweetness is adjustable. As written, I think the amount of maple syrup is just enough to give a hint of sweetness without overpowering the delicate matcha flavor, but you are welcome to use more or less to suit your taste. You can also use sweeter chocolate if you're not a fan of the super dark stuff like the 85% dark I used in the photos.
- This is a great recipe to use for meal prep. The prepared matcha oatmeal will stay good in the fridge for up to 5 days, so if you make a double batch and divide it into five containers, you'll have a quick plant-based breakfast ready to go all work week.
Ingredients
Here's a quick look at the ingredients you'll need to make Matcha Overnight Oats. The full recipe is in the recipe card at the end of this post.

- Old-fashioned rolled oats - make sure to use certified gluten free oats, if necessary
- Matcha powder - I use Maeda-En's culinary grade matcha powder
- Unsweetened plant milk - I like soy milk best, but almond milk works well, too
- Tahini - unsalted is best for this recipe
- Pure maple syrup
- Dark chocolate - I used 85% dark
- Pure vanilla extract
- Salt
Recipe Steps
In a medium bowl, whisk together the tahini, maple syrup, and vanilla until smooth.


Next, slowly whisk the plant milk in.


Add the oats, matcha powder, and salt and stir until creamy and thoroughly combined.


Divide evenly into three jars or lidded containers. Cover and refrigerate overnight.

When you're ready to eat, add the shaved dark chocolate to serve.

Ingredient Substitutions
Here are some ideas for substitutions you can try.
- Dark chocolate - if you don't like dark chocolate, you can use your favorite vegan chocolate bar or chocolate chips, or leave the chocolate out
- Tahini - this would also be good with a neutral-flavored nut butter like almond butter or cashew butter (unsalted and unsweetened, so it doesn't take away from the matcha flavor)
Helpful Tips
- To make shaved chocolate, use a vegetable peeler to carefully shave the edge of the chocolate bar. Store the chocolate shavings in the refrigerator until you're ready to use them.
FAQs
The type of matcha you decide to buy depends on what you're going to use it for. If you're mostly using it for cooking, look for culinary grade matcha powder. If you're mostly going to drink it by itself or in matcha lattes, ceremonial grade matcha is the best choice. Whatever you choose, make sure you find a high quality matcha powder so you don't end up with a bitter flavor.
Also, just a heads up - there are a lot of products out there labeled "matcha powder" but have a bunch of other ingredients added. Look for pure matcha powder with nothing else added.
Can I heat up overnight oats?
If cold oatmeal isn't your thing, you can definitely heat up overnight oats on the stovetop or in the microwave. To use the stovetop, transfer a serving of overnight oats to a small saucepan and heat over medium heat, stirring often, until the oatmeal is warmed through. If using the microwave, make sure your overnight oats are in a microwave-safe container. Microwave them on high for two minutes, stirring every 30 seconds, until the oats are warmed to your liking.
If you're adding dark chocolate to your overnight oats, you can either add it before heating them up or after. Either way is delicious!
Are overnight oats healthy?
Overnight oats are a nutrient-dense, fiber-filled breakfast and are a much healthier way to start the day than sugary breakfast cereal. Just be conscious of how much added sweetener you use, and make it a point to include whole food additions like nuts, seeds, fruit, and antioxidant-rich ingredients like matcha and low-sugar dark chocolate.
