Here are my favorite Hazelnut and Chocolate Brownies with Whey Protein, Oats flour, and other favorite ingredients. The best part about these protein brownies is that they aren't dry. This is true for all recipes I make with protein powder. Try these Best Protein Pancakes and No Bake Pumpkin Pie Energy Balls
Homemade Low calorie Protein Brownies
Low-calorie protein brownies make up for most of my mid-morning, post-workout snack. Just like these Strawberry Avocado Toast and Healthy Kiwi Chia Pudding

Sometimes, when I'm going in for a heavy workout - suppose a leg day or a back day, I don't mind taking one brownie as it provides the essential carbs required to train that muscle group.
It's the best Protein Brownie which you can ever think of. The hazelnuts adds a crunchy, nutty layer on top. The unsweetened chocolate chips make every bite worthwhile.

How to Make Healthy Protein brownies with protein powder
You can skip the nuts if you don't like them while making protein brownies recipes with protein powder. I, however like hazelnuts, macadamia nuts, and any other form of nuts. These nuts also make it to my table even when I'm not making a brownie. But, feel free to skip the nuts if you don't like them or allergic to nuts.
- STEP 1: Preheat Oven and Prepare baking dish
Preheat oven to 350 degrees F or 180 degrees C. Line an 8x8 inch square baking dish with organic parchment paper and set aside.
- STEP 2: Melt Unsweetened Dark Chocolate
I use the best quality unsweetened dark chocolate baking bar. One that is 100% Cacao. But you can swap it with 70% or 80% or 90% Cacao based on your liking.
To melt chocolate, first roughly chop them up on a cutting board. I love my Olive wood cutting board by Forest Decor.
Transfer them to a medium-sized microwave safe bowl and melt them with coconut oil.
I prefer to melt chocolate in 30-second increments. It is a technique that I've been following for ages now. And it never fails. Ensure you whisk appropriately until the chocolate is smooth, silky, and lump-free.
- STEP 3: Combine all ingredients in a bowl
In the same bowl, add all other ingredients. Many people prefer adding the wet and dry ingredients separately. But, honestly, I'm too lazy for that. And, the best part, it didn't make any difference. Whisk everything until well combined.
- STEP 4: Bake
Transfer to the prepared baking dish and bake for 30-35 minutes or until a toothpick comes out with a few moist crumbs at the center.
Can I add protein powder to boxed brownie mix?
That's a really smart question. And, I really like the way you are looking ahead to save time. Well, yes. You can add protein powder to boxed brownie mix and bake your brownies. But, But, But, I can't promise you that they won't be dry or that they will be high in protein. They might have added certain artificial agents to make the boxed brownie mix which might be high in sugar content. So make sure you read the nutrition label cautiously and make your best choice.
Why are my protein brownies dry?
You might have added too many dry ingredients without enough wet ingredients to balance it off. Whey Protein soaks water. So probably, you need some liquid agents like milk or water or eggs to balance out the moisture content in your Whey Protein Brownies.
What are protein brownies made of?
Protein brownies are made of Whey Protein Powder, Ground oats, Coconut flour or Almond Flour, eggs, vanilla extract, baking powder, and cocoa powder, along with melted dark chocolate if you are making chocolate protein brownies.
What is the best nut for brownies?
It totally depends on the kind of nut you enjoy using for your brownies. My favorite nuts are hazelnuts and Macademia nuts. But that's not it. You could use Almonds, Pecan nuts, Cashew nuts, Walnuts, Pistachios, and etc.
