Brownie Batter Overnight Oats are a yummy way to start your day! These oats are mixed with cocoa, a touch of maple syrup, and creamy yogurt, making breakfast feel like dessert.
I love prepping these the night before, so I wake up to a delicious treat waiting for me in the fridge. Honestly, who wouldn’t want brownie batter in the morning? 😋
Key Ingredients & Substitutions
Rolled Oats: These are the base of the recipe. They soak up the liquid without getting too mushy. If you don’t have rolled oats, quick oats can work too, but the texture may be slightly different.
Cocoa Powder: Unsweetened cocoa powder adds the chocolate flavor. If you want a lighter chocolate taste, try using carob powder. For dairy-free options, ensure it’s cacao that is made from raw ingredients.
Greek Yogurt: This adds creaminess and a protein boost. If you’re dairy-free, any plant-based yogurt can substitute. I often use coconut yogurt for its rich flavor.
Sweetener: Maple syrup is my favorite, but honey works well, too. For a low-sugar option, mashed ripe banana can lend sweetness without added sugars.
Chia Seeds: While optional, they help thicken the mixture and add nutrients. If you’re out of chia seeds, flaxseeds can be a great substitute!
How Do I Make the Oats Super Creamy?
To achieve that rich, creamy texture that mimics brownie batter, focus on the way you mix your ingredients. Make sure to stir very well to integrate all components. Use Greek yogurt for extra creaminess, and don’t skip soaking the oats overnight.
- Combine dry ingredients first, ensuring cocoa is evenly mixed.
- Gradually add wet ingredients and stir until smooth.
- Let it sit overnight in the fridge—this is key as it helps the oats soak up the liquid and soften.
- In the morning, if it feels thick, adjust with a splash of milk for desired creaminess.
These steps will help you avoid any clumpy or dry oats, making sure each bite is delicious and creamy!

Brownie Batter Overnight Oats
Ingredients You’ll Need:
- 1/2 cup rolled oats
- 1 tablespoon cocoa powder (unsweetened)
- 1 tablespoon chia seeds (optional, for thickness and nutrition)
- 1 cup milk of choice (dairy or plant-based)
- 1/2 cup Greek yogurt or plant-based yogurt (for creaminess)
- 1 tablespoon maple syrup or honey (adjust to taste)
- 1/2 teaspoon vanilla extract
- Pinch of salt
- Chocolate chips for topping (as desired)
- Peanut butter or almond butter (for topping)
How Much Time Will You Need?
It takes about 10 minutes to prepare your oats, and then you just let them chill overnight in the fridge (or at least 6 hours). This means you can easily whip them up in the evening and have a tasty breakfast ready to go the next morning. Super simple!
Step-by-Step Instructions:
1. Mix the Dry Ingredients:
In a mason jar or sealable container, combine the rolled oats, cocoa powder, chia seeds (if using), and a pinch of salt. Use a spoon or a small whisk to mix it all together until the cocoa is evenly distributed throughout the oats.
2. Add the Wet Ingredients:
Pour in the milk, Greek yogurt, maple syrup, and vanilla extract into the oat mixture. Stir well, making sure everything is combined smoothly. You want a really creamy mixture!
3. Refrigerate Overnight:
Seal the container with a lid and pop it in the fridge. Let it sit overnight (or for at least 6 hours) so that the oats absorb the liquid and soften. This is what turns your oats into a delicious breakfast!
4. Stir and Adjust Consistency:
When you’re ready to enjoy your oats, take them out of the fridge and give them a good stir. If the mixture seems too thick, you can add a splash more milk to loosen it up to your liking.
5. Add Toppings:
Top with a generous dollop of peanut or almond butter, and sprinkle some chocolate chips on top for that brownie batter effect. Feel free to add any other toppings you like, such as nuts or fresh banana slices.
6. Time to Dig In!
Grab a spoon and enjoy your Brownie Batter Overnight Oats right from the jar! It’s a tasty and satisfying start to your day that feels like a treat.
This recipe is not only delicious but also packed with nutrients to keep you fueled throughout the morning. Enjoy!
Can I Use Instant Oats Instead of Rolled Oats?
Yes, you can use instant oats, but keep in mind that they will absorb the liquid more quickly, making the mixture thicker. If using instant oats, reduce the soaking time to about 4 hours to prevent them from becoming too mushy.
How Can I Make This Recipe Vegan?
To make it vegan, simply use a plant-based yogurt and any plant-based milk, like almond or coconut milk. You can also substitute maple syrup for honey to keep the recipe fully vegan!
Can I Double the Recipe for Meal Prep?
Absolutely! This recipe is perfect for meal prep. Just double the ingredients and store in separate jars for easy grab-and-go breakfasts throughout the week. Just remember to keep an eye on the final total liquid as it might need a little adjustment.
How Do I Store Leftover Overnight Oats?
If you have leftovers, store them in an airtight container in the fridge for up to 3 days. The oats might continue to absorb liquid, so you may need to stir in a little extra milk when you’re ready to eat!
