Flourless 4-Ingredient Keto Protein Brownies

Flourless Protein Brownies

It’s no secret that we are big fans of healthy brownie recipes here. After my flourless protein brownies, flourless applesauce brownies and healthy no bake brownies, it was time to give a keto protein recipe a solid effort.

These brownies only need FOUR ingredients-

  • Pureed pumpkin
  • Cocoa Powder
  • Smooth nut or seed butter
  • Protein Powder of choice

That’s it!

Flourless 4-Ingredient Keto Protein Brownies

Why protein-packed brownies? Ironically, these healthy brownies were developed to substitute a protein shake after a workout. I found that by using certain protein powders, I didn’t need to use any flour or wheat. You guys have also asked for more keto protein powder recipes!

What resulted was a gooey, fudgy protein brownie, also egg-free. This means my vegan and paleo friends can also enjoy these brownies, guilt-free!

The trick to perfect, delicious flourless protein brownies is to use the right kind of protein powder. The market is saturated with various brands of protein powder, and some will yield perfect brownies. Other brands will leave you with hockey pucks- No Bueno!


Can vegans eat whey protein powder is easily my most common question, along with whether or not whey protein is plant based or animal derived? The answer to that is no, they cannot. It’s one of the reasons I never use a strict whey protein powder. Furthermore, I find whey protein powders to yield terrible results! 

I always test my protein powder recipes with 3 kinds of protein powders-

Casein protein powder While this protein powder is NOT vegan-friendly or plant-based, it is ketogenic-friendly and super low carb. I love using casein protein powder as it bakes beautifully, and has a naturally thick and creamy texture. 

Brown rice protein powder For my vegan and gluten-free friends, brown rice protein powder is perfect for baking or using in my protein powder recipes. Although a little chalky, it is also thick and when used correctly, is super creamy. 

Paleo keto protein powder This protein powder is suitable for the paleo diet, and as such, is also keto-friendly and super low carb. Unless you follow a paleo lifestyle, I’d stick to one of the above blends. 

Please note- I can only vouch for the above brands’ protein powder and flavors. If you do use another blend or brand, the outcome may be different.

Another popular question I get asked, especially with most of my recipes (like this one!) calling for the former. As someone who has family members with a peanut allergy, unless my recipe is peanut butter specific (like these no bake peanut butter cookies or these chocolate peanut butter bars), I stick to almond butter.

Peanut butter is also not paleo-friendly. Some may argue whether or not you can also have peanut butter on a keto diet. 

Regardless of which nut or seed butter you choose to use, ensure it is drippy and smooth. This will avoid the brownies have clumps, and allow the mix to be well combined. 


To keep these protein brownies keto and sugar-free, you’ll notice that there is no sugar added. You have three options here-

  1. Ensure that your protein powder is pre-sweetened
  2. Add some liquid stevia or granulated sweetener of choice

The third option is the one I used- Cover it in chocolate! Before you roll your eyes and claim that chocolate isn’t keto or chocolate isn’t paleo or vegan, I have you covered.

I always use either stevia sweetened chocolate chips (keto, low carb and sugar free) or dairy free mini chocolate chips (vegan and paleo friendly). Both melt beautifully and if you choose to go this route, you won’t need to sweeten your brownies!

  • Preheat the oven to 350F/180C. Line a small loaf pan with parchment paper and set aside.
  • In a mixing bowl, add all your ingredients and mix very well- The batter should be thick and smooth. 
  • Pour the brownie batter in the lined pan and bake for 12-15 minutes, or until a skewer comes out 'just' clean. Allow brownies to cool in the pan completely. For best results, refrigerate after for a further 2 hours.
  • Once cooled, cut into 8 pieces. Either enjoy as is, or melt the chocolate chips of choice and dip each brownie in it until evenly coated. 


* See post content for protein powder recommendations. A standard scoop should generally be 32-34 grams.
** Adjust accordingly. I find 1 serving (5-6 drops) to be sufficient sweetness. 
Flourless Keto Protein Brownies (Paleo, Vegan, Low Carb) should be kept refrigerated at all times. They are freezer friendly too.

    1. Hey Arman, why don’t you ever recommend whey protein in your smoothie/ice cream or baked recipes? You say it messes with the texture– what does it actually do to the textures of each? Thank you!
