Step‑by‑Step Instructions for Decadent & Healthy Brownie Batter Overnight Oats You’ll Want Every Morning
Step 1: Combine Dry Ingredients
In a medium bowl or a mason jar, add 1 cup of rolled oats, 2 tablespoons of chia seeds, and 3 tablespoons of unsweetened cocoa powder. Stir them together until they’re evenly mixed, ensuring that the cocoa is well-distributed among the oats. This step sets the base for your decadent & healthy brownie batter overnight oats.
Step 2: Add Wet Ingredients
Next, incorporate the wet ingredients into your dry mixture. Add 1 cup of Greek yogurt, 1 cup of your preferred milk, 2 tablespoons of maple syrup, and 1 teaspoon of vanilla extract. Use a whisk or spoon to blend everything together until smooth and creamy. You want to achieve a thick but pourable consistency here.
Step 3: Mix Thoroughly
Take a moment to ensure your decadent brownie batter mixture is free of clumps. Thoroughly mix until there are no visible dry ingredients or lumps of cocoa powder left. This will guarantee a smooth, uniform texture in your overnight oats, making each bite perfectly chocolatey.
Step 4: Add Optional Ingredients
If you’d like to elevate your brownie batter overnight oats, now’s the time to fold in any optional add-ins. Consider mixing in 1/4 cup of mini chocolate chips, a tablespoon of nut butter, or a scoop of protein powder. Gently stir these ingredients until they’re evenly distributed throughout the mixture for added flavor and richness.
Step 5: Refrigerate
Once everything is well combined, cover the bowl with a lid or plastic wrap, or seal your mason jar tightly. Refrigerate the mixture for at least 4 hours, although overnight is ideal. This chilling time allows the oats and chia seeds to absorb the moisture and flavors, achieving that creamy brownie batter consistency.
Step 6: Serve
When you’re ready to enjoy your decadent & healthy brownie batter overnight oats, give them a good stir to mix everything up again. If desired, top your oats with sliced bananas, fresh berries, or additional chocolate chips to enhance the experience. You can enjoy them straight from the jar or transfer to a bowl for a more leisurely breakfast.
