Introduction
These brownie batter overnight oats are chocolate-packed, high in protein and make the perfect fuel on the go. These oats are extra thick, somewhere between cookie dough and brownie batter, though the consistency is easy to adjust.
Overnight oats make such a handy breakfast for busy mornings. They’re portable, adaptable to suit your dietary needs and preferences, can be eaten cold and take just minutes to prepare the night before.

Ingredients
The complete list of ingredients with measurements is located in the recipe card at the end of the post.
- Oats: Overnight oats are best made with rolled oats or large flake oats but you can also use quick oats. Do not use steel cut oats.
- Milk: You can use any plant-based milk you enjoy such as almond milk, oat milk or cashew milk. You can substitute water if needed but they’ll be creamier with milk.
- Protein Powder: This recipe calls for a pea protein vegan protein powder. Most vegan protein powders are made form pea protein, so you could use brands like Vega, Kaizen, Orgain, PVL, KOS or Naked Nutrition. Pea protein absorbs a lot of moisture so its best for a thick, chewy texture.
- Cocoa Powder: You can use cocoa powder, dark cocoa powder or raw cacao powder.
- Optional: I like to add vanilla and salt to enhance the flavour. Depending on the protein powder used, you may also want extra sweetener. You can use stevia for sugar-free, maple syrup or honey.
Variations & Add-Ins
- For more heathy fats and thickening, add 1-2 tbsp chia seeds, ground flax or hemp seeds (hemp seeds won’t thicken but flax and chia seeds will).
- Use half milk and half yogurt for an even thicker, creamier texture.
- Add 2-3 tbsp shredded coconut for chocolate coconut overnight oats.
- Powdered peanut butter works well for peanut butter flavour without overdoing the calories. You can swap half of the protein powder for peanut butter powder, or add 2-3 tbsp peanut butter powder plus some extra milk.
- Zucchini Chocolate Chip Oats: Add up to 1/2 cup finely grated zucchini and 1-2 tbsp cacao nibs or mini chocolate chips.
- Mocha Oats: Add 1 tsp espresso powder and/or replace 1/2 cup of the milk with coffee.
- Chocolate Orange Oats: Add 1 tsp orange zest.
- Other spices that work well are 1 tsp cinnamon, 1/8 tsp cayenne pepper or 1/4 tsp nutmeg.
Step-by-Step Instructions
Combine all of the ingredients in a sealable jar or any airtight container and shake or stir well.
The recipe calls for 3/4 cup milk, 1/2 cup rolled oats and 44 g of protein, which is one scoop of Vega protein but may be more than one scoop for other brands. For best results, use a digital scale to measure the ingredients.
Make sure you mix well until there are no clumps of cocoa powder, protein powder or oats remaining. Seal the container and place in the fridge overnight or at least for 4-6 hours.
In the morning, give the oats a stir and enjoy them straight from the container or transfer them to a bowl. You can eat them as is or with your choice of toppings.
Common toppings include fresh berries, sliced bananas, chopped nuts, seeds, dried fruit, and granola.
Topping Ideas
- Chocolate chips or cacao nibs.
- Sliced banana.
- Peanut butter, almond butter, or other nut or seed butter.
- Any nuts or seeds like walnuts, pecans, hemp seeds, pumpkin seeds.
- Fresh berries like sliced strawberries or raspberries.
- Chia seed jam.
- Coconut yogurt.
- Granola.
- Shredded coconut.
- Dried cherries, cranberries or raisins.
Recipe FAQs
The choice between milk and water for your overnight oats comes down to your taste and dietary needs. Milk provides a creamier, richer texture than water and adds nutrition. You can use any milk such as almond milk, soy milk or cashew milk.
If you’d like to reduce the calories or don’t have milk on hand, water works well too though it won’t provide the creaminess and flavour of milk.
You can also use half milk and half yogurt for an even creamier texture.
Overnight oats and traditional cooked oatmeal are both healthy breakfast options, and the choice between them depends on your preference.
In terms of health, both overnight oats and oatmeal can be nutritious choices. It’s more about your personal preferences, time constraints, and how you like to enjoy your oats. Some people prefer the convenience and texture of overnight oats, while others enjoy the warmth and cooking process of traditional oatmeal. You can make either option healthier by choosing nutritious toppings and limiting added sugars.
Both overnight oats and oatmeal start with oats as the main ingredient. Oats are a nutritious whole grain that is rich in fiber, particularly beta-glucans, which can help lower cholesterol levels and promote heart health. They also provide essential vitamins and minerals like magnesium, iron, and B vitamins.
You can use any protein powder you enjoy but I really like pea protein powder for this recipe. Most plant-based protein powders are made from pea protein so you can just check the label.
Pea protein is a plant-based protein derived from yellow peas. It’s known for its high protein content and excellent amino acid profile but I like it for it’s texture and consistency in oatmeal.
I also like blended plant-based protein powders that may have a blend of proteins like pea, rice, hemp, soy and others. These blends provide a wider range of amino acids.
You can use chocolate, vanilla, peanut butter, mocha or any other flavour you think would work well in chocolate oats. Note that if you use unsweetened or plain protein, you’ll need to add sweetener to the recipe.
You can make your overnight oats in any container you want by my go-to is mason jars. Glass food storage containers are also a good choice, or just use a bowl and cover it in the fridge overnight. I like mason jars or glass containers if I’m taking them to-go in the morning.
You can also get these super cute, reusable silicone sleeves for mason jars for extra durability and to use like a coffee jacket if you want to take something hot in your jar.
Raw cacao is made by cold-pressing unroasted cocoa beans whereas cocoa powder has been roasted at high-temperatures.
Unfortunately, roasting cacao at high-temperatures lowers the nutritional value so to reap the amazing health benefits of chocolate, it’s cacao powder that that you’re after.
I use both cacao powder and cocoa powder but I do like using cacao where I can.
High in antioxidants, cacao has been show to lower insulin resistance, protect your nervous system, lower blood pressure, reduce the risk of heart disease and stroke, fight free radicals, support a sense of well-being and provide important minerals like magnesium iron, calcium and zinc.
It’s the obvious choice but it’s also more expensive. Use it if you like but both raw cacao powder and cocoa powder work just fine in this recipe.
Recipe Notes
- This recipe comes out very thick with a doughy consistency. If you prefer more of a traditional oatmeal consistency, increase the almond milk to 1 cup.
- For sweetness, it depends on the protein powder used as some are sweeter than others. You may not need to add sweetener. Sweeten to taste with a pinch or stevia, a few drops liquid stevia or 2-3 tsp maple syrup or other liquid sweetener.
- Some readers have had issues with their oats being “soupy”. If you follow the recipe amounts as listed, these come out very thick with a batter-like consistency. For best results, please follow the recipe and measure your ingredients using a kitchen scale.
Storing Instructions
- Store overnight notes in an airtight container like a mason jar or Weck jar in the fridge for 3-4 days.
- While they may technically last a bit longer, the texture and flavor can deteriorate over time. It’s best to make only as much as you can consume within this timeframe.
- Overnight oats are typically enjoyed cold but they can be reheated in the microwave or in a small pot on the stovetop.

This looks so good and so many people seem to love it! I’ve never made overnight oats and am wondering if “quick rolled oats” would possibly work?
Yes, you can use quick oats. Thanks.
OMG these are decadent and so filling. I added a mashed banana to the mix and it was heaven. Delicious, added to my weekly rotation. 🙂
Yum! Glad you enjoyed them!
This recipe sounds delicious.
Could you cook them up like a pancake?
They won’t cook through solid but you could cook them on the stovetop as hot oatmeal.
Super delicious!!! However my first batch came out a little too salty so I tweaked the amount I added and its so good!!!
