🧄 Very useful ingredient notes

Ingredients laid out for matcha overnight oats: plant-based milk, plant-based yogurt, rolled oats, maple syrup, ground flaxseed, matcha powder, not pictured is hot water at 175 degrees Fahrenheit

Matcha powder - matcha is Japanese green tea that is ground into a powder. Use a good quality matcha, preferably organic. Save your highest quality, ceremonial grade matcha for prepared tea or matcha lattes, though, where you can enjoy it fully.
Rolled oats - don't use quick oats for this recipe, they turn out too mushy.
Ground flax - thickening agent
Plant-based yogurt - adds extra creaminess and thickness.

📋 Substitutions and variations

Here are some suitable substitution options for the ingredients:

Flax - use chia seeds (white or black) instead of ground flaxseed. Or, omit them (but, keep in mind that it will not be as thick if you don't use either of these in your oats).
Maple syrup - substitute with a sweetener of your choice, such as: cane sugar, brown sugar, agave nectar or coconut sugar. Or, omit entirely, if you don't want it sweetened at all.
Nut-free - make this nut-free by using a nut-free plant milk, such as soy milk, rice milk or oat milk.
WFPBNO - make this whole food plant based no oil by using plant-based milk, yogurt and preserves with no added oil or refined sugar.
SOS-free - make this salt-, sugar- and oil-free by using a plant-based milk, yogurt and preserves with no added salt, sugar or oil.

Here are some variation ideas for these matcha overnight oats:

Matcha Raspberry Oats - add fresh or frozen raspberries to the top of the oats for raspberry matcha overnight oats
Matcha Strawberry Oats - add fresh or frozen strawberries to the top of the oats for strawberry matcha overnight oats
Blue Matcha Oats - have you ever tried blue matcha? It's ground butterfly pea flower herbal tea. So, there's no caffeine in it, like green tea matcha and it's a beautiful blue color, so would be great for kids and anyone who is sensitive to caffeine.

🔪 Instructions

Step-by-step instructions for how to make vegan matcha overnight oats.

Step 1: Heat filtered water in an electric kettle to 175℉/80℃, which is hot water, but not boiling. If you use boiling water to make your matcha, it will be bitter.

Process - step 2 - add matcha powder to jar

Step 2: Add matcha powder to a heat-proof glass mason jar that is pint-size. If you have a matcha whisk and bowl, you can use that to prepare your matcha, then pour it into a separate container for your oats.

Process - step 3 - pour hot water in and whisk

Step 3: Pour ¼ cup of hot water in the jar. Using hot water will steep the matcha and bring out its flavor.

Step 4: Using a mini whisk or fork, whisk the matcha in a rapid back and forth motion, until no clumps remain. (Do NOT put the lid on the jar and shake to combine the matcha. This is dangerous, since pressure will build up inside.)

Step 7: Add plant-based milk and yogurt to the jar.

Step 8: Add ground flaxseed.

Step 9: Add maple syrup.

Step 10: Add rolled oats to jar.

Step 11: Stir everything together.

Step 12: Cover jar with lid and place jar in refrigerator overnight or at least 2 hours. When you're ready to eat them, pull it out of the fridge and eat cold or warm up in microwave for 30-60 seconds.

Expert tips

Use a canning funnel to add ingredients to jars (especially regular mouth jars, which are more narrow) without making a mess
Make several of these at once, so you have breakfast or an afternoon pick-me-up snack ready for several days.

🍳 Equipment

a heat-proof container to hold your overnight oats that holds 1 pint (about 2 cups, 16 ounces or 550 milliliters). I recommend using wide mouth pint size mason jars.
a small, mini whisk (pictured below) or fork. If you have a matcha whisk and bowl, use that to make your matcha first, then pour into your overnight oats container.

🥡 Make ahead and storage tips

Overnight oats are perfect for meal prep and batch cooking. Make them Sunday night to have breakfast ready to go all week long. Store overnight oats in the refrigerator, combined, for up to 5 days.

To meal prep these matcha latte oats, multiply the recipe based on how many you're making. Then, whisk up all the matcha in one container, then divide equally between the containers, so you don't have to whisk them all separately.
