Brownie Batter Overnight Oats are a fun and yummy breakfast. You get the chocolatey goodness of brownies right in your morning bowl, all while keeping it healthy!
Mix oats, cocoa, and milk, then let them chill overnight. In the morning, you’ll have a delicious treat that tastes like dessert! I love adding a little peanut butter for extra flavor. 😋
Key Ingredients & Substitutions
Rolled Oats: These oats are the base of your overnight oats. Quick oats will work in a pinch, but they can make the texture mushy. Stick with rolled oats for the best results!
Chia Seeds: Chia seeds help thicken the mixture and add a nice boost of fiber. If you’re out of chia seeds, you can use ground flaxseeds as a substitute, but adjust the amount for consistency.
Cocoa Powder: Unsweetened cocoa powder gives that rich chocolate flavor. If you prefer a sweeter taste, you could use Dutch-processed cocoa powder, which is milder and sweeter.
Maple Syrup or Honey: Both sweeten the mix. Maple syrup is plant-based, while honey offers a unique flavor. Feel free to adjust the sweetness based on your preference!
Milk: You can use almond milk, oat milk, or soy milk instead of dairy milk. Each type brings its own flavor, so pick your favorite!
How Do I Get the Right Texture for My Overnight Oats?
Achieving the right texture is key to enjoyable overnight oats. Here’s a simple guide for perfect results every time:
- Don’t skip the chia seeds—these help thicken the oats while absorbing moisture.
- Combine dry ingredients first to ensure everything is evenly mixed before adding liquid.
- Adjust milk for desired thickness: Use less for a thicker consistency and more for a creamier texture.
- Allow it to soak in the fridge overnight to let all flavors meld and the oats soften properly.
In the morning, give your oats a quick stir. If it’s too thick, add a splash of milk to loosen it up. Enjoy! 😊

How Much Time Will You Need?
This recipe takes about 10 minutes to prepare, and then you’ll need to let it chill in the fridge overnight (at least 6 hours). So, you can whip it up in the evening and enjoy a delicious breakfast the next morning!
Step-by-Step Instructions:
1. Mix the Dry Ingredients:
In a jar or bowl, combine the rolled oats, chia seeds, cocoa powder, maple syrup (or honey), vanilla extract, and salt. Stir them together well to ensure everything is evenly distributed.
2. Add the Wet Ingredients:
Pour in the milk and mix again until all the dry ingredients are moistened. You’ll want everything to be well incorporated.
3. Stir in Peanut Butter and Chocolate Chips:
Now, add the peanut butter and 2 tablespoons of mini chocolate chips. Mix until everything is combined and the chocolate chips are evenly distributed throughout the mixture.
4. Refrigerate Overnight:
Cover your jar or bowl with a lid or plastic wrap. Pop it in the refrigerator and let it chill overnight. This will allow the oats to soak up the liquids and soften nicely.

Can I Use Instant Oats Instead of Rolled Oats?
While you can use instant oats, they will absorb liquid much faster and may result in a mushier texture. If possible, stick with rolled oats for the best consistency!
Can I Make These Overnight Oats Vegan?
Absolutely! Just use maple syrup as your sweetener and any plant-based milk, like almond milk or oat milk, to keep the recipe entirely vegan.
How Long Do Leftover Overnight Oats Last?
Your brownie batter overnight oats can be stored in the fridge for up to 3 days. Just make sure to keep them in an airtight container to maintain freshness!
Can I Add Other Mix-ins or Toppings?
Definitely! Feel free to experiment with different nut butters, fruits like banana or berries, or even add in nuts and seeds for extra crunch and nutrition!
