Old fashioned rolled oats: The hearty base that softens overnight into creamy deliciousness without losing satisfying texture.
Protein powder (vanilla or chocolate): Adds a boost of protein and enhances the rich flavor, making the oats more filling.
Unsweetened vanilla almond milk: Keeps things dairy-free while lending a subtly sweet and nutty undertone.
Cocoa powder: The hero of the brownie flavor, bringing deep chocolate notes and a beautiful dark hue.
Maple syrup: Natural sweetness that rounds out the flavors without overpowering them.
Vanilla extract: Adds warmth and depth that elevates the chocolatey richness.
Pinch of sea salt: Just enough to balance sweetness and intensify the chocolate flavors.
Chocolate chips: Little pockets of melty chocolate magic sprinkled on top for texture and indulgence.
Chopped walnuts: Provide a satisfying crunch and a hint of earthiness.
Peanut butter (optional): Offers a creamy, nutty twist that beautifully complements the chocolate notes.

How to Make Brownie Batter Overnight Oats Recipe

Step 1: Combine Wet and Dry Ingredients

The starting point is to gather everything into one bowl or jar. Add the oats, protein powder, almond milk, cocoa powder, maple syrup, vanilla extract, and a pinch of sea salt. Stir them thoroughly until the protein powder dissolves completely and the mixture is smooth and well blended. This sets the stage for the oats to soak in all those rich flavors overnight.

Step 2: Refrigerate Overnight

Seal your container tightly and place it in the fridge for at least 8 hours. This slow chilling process allows the oats to absorb the liquid and swell up into a creamy, pudding-like texture that holds all the chocolatey goodness in each bite.

Step 3: Stir and Adjust Consistency

In the morning, take out your oats and give them a good stir. You’ll notice they thicken up substantially as the oats soak, so feel free to add a splash additional almond milk if you prefer a looser consistency. This also revives that creamy texture making it irresistible.

Step 4: Add Your Toppings

Divide the oats into two bowls or jars. Now comes the fun part—top each serving generously with chocolate chips, chopped walnuts, and a dollop of peanut butter if using. These finishing touches give your overnight oats extra bursts of flavor and texture, making breakfast feel truly special.

Garnishes

To make your Brownie Batter Overnight Oats Recipe pop, don’t hesitate to pile on more chocolate chips or sprinkle on extra chopped nuts for crunch. A drizzle of peanut butter or even a spoonful of Greek yogurt can add creaminess and a touch of tang that balances the sweetness beautifully. Fresh berries, like raspberries or strawberries, can also offer a refreshing contrast that brightens the dish.

Side Dishes

This recipe stands strong on its own, but pairing it with a side of fresh fruit salad or a small smoothie can create a well-rounded, energizing breakfast. If you prefer something savory to complement the sweet oats, try a light avocado toast or boiled eggs for added protein without overpowering those chocolate flavors.

Creative Ways to Present

Layering the overnight oats, chocolate chips, and nuts in a clear glass jar creates a luscious parfait effect that’s as pretty as it is tempting. You could also swirl in a spoonful of peanut butter just before serving to create a marbled effect, or use fun-shaped bowls or mason jars to brighten up your morning table and bring a little extra joy to breakfast time.

Make Ahead and Storage

Storing Leftovers

Leftover Brownie Batter Overnight Oats Recipe can be kept refrigerated in an airtight container for up to 3 days. This makes it perfect for meal prepping a few breakfasts at once. The flavors will continue to deepen over time, but the texture may thicken, so just stir in a splash of almond milk before eating.

Freezing

Freezing overnight oats is less common due to texture changes after thawing, but if needed, freeze in a sealed container for up to one month. Thaw overnight in the fridge and stir well before eating. Add extra liquid as necessary to bring back that creamy consistency we all love.

Reheating

While overnight oats are delicious cold, they can be gently warmed if preferred. Heat in the microwave for 20-30 seconds, then stir and add a little almond milk if needed. Avoid overheating to keep the texture pleasant and the chocolate flavor rich and smooth.

FAQs

Can I use a different kind of milk?

Absolutely! While the recipe calls for unsweetened vanilla almond milk, feel free to use oat milk, cow’s milk, or any plant-based milk you love. Just keep in mind that sweeter milks can alter the sweetness level of your oats.

Is protein powder necessary in the Brownie Batter Overnight Oats Recipe?

Protein powder is optional but highly recommended if you want to boost the protein content and achieve that rich brownie flavor. Vanilla or chocolate protein powders work best and blend seamlessly into the oats.

How can I make this recipe nut-free?

Simply omit the walnuts and use a nut-free milk alternative like oat or soy milk. You can swap peanut butter for sunflower seed butter if you want to keep that creamy nutty element.

Can I prepare more than two servings at once?

Definitely! Multiply the ingredients by the number of servings you want and mix everything in a larger container or divide into separate jars. This recipe scales beautifully for meal prepping busy mornings.

What’s the best way to make it less sweet?

Reduce or omit the maple syrup and choose an unsweetened protein powder. You can rely on the natural nuttiness from the almond milk and add sweetness later with fruit or a drizzle of honey.
