Combine Ingredients: In a mason jar or airtight container, add the rolled oats, protein powder, milk, cocoa powder, honey or maple syrup, vanilla extract, chia seeds (if using), mini chocolate chips (if using), chopped nuts, and a pinch of salt.
Mix Well: Use a spoon or a fork to thoroughly mix all the ingredients together until everything is well combined and there are no clumps of cocoa powder.
Refrigerate Overnight: Once mixed, cover the jar with a lid and refrigerate it overnight or for at least 4-6 hours. This allows the oats to soften and absorb the flavors, resulting in a creamy and delicious texture.
Serve and Enjoy: In the morning, give the oats a quick stir to ensure everything is evenly distributed. You can enjoy the overnight oats straight from the jar or transfer them to a bowl and add your favorite toppings, such as fresh fruit, nuts, or additional chocolate chips.
Notes
Store: Leftover overnight oats can be stored in the refrigerator for up to 2-3 days. Simply keep them in an airtight container or mason jar until ready to enjoy. If the oats become too thick upon refrigeration, you can add a splash of milk to loosen them up before serving.Meal Prep: To save even more time during busy mornings, consider meal prepping multiple servings of brownie batter overnight oats at once. Simply double or triple the recipe and divide the mixture into individual jars or containers. Then, grab and go as needed throughout the week for a hassle-free breakfast option.Customize: Feel free to customize your brownie batter overnight oats to suit your taste preferences. If you prefer a sweeter flavor, you can add more honey or maple syrup. Likewise, if you're a chocolate lover, feel free to add extra cocoa powder or chocolate chips.
