Healthy Flourless Protein Brownies (grain free!)

Healthy Flourless Protein Brownies (gluten free & low calorie)

These healthy brownies have been my go-to snack for my weekly meal prep routine the past few weeks. I just can’t get enough of them! Unlike my fudgy brownies, these healthy brownies are more fluffy and less dense. They’re super easy to make. Plus, they’re gluten free, grain free, paleo, and vegetarian.

And, to make them even better, I’ve added my collagen peptides to sneak in some extra protein. Of course, the added protein isn’t necessary. You can totally make these brownies without the protein, but if you’re trying to increase your overall daily protein intake, this is an easy way to do it. Plus, it makes the brownies more filling.

Healthy Brownies – Calories and Macros

One reason these brownies are perfect to work into your healthy meal prep routine is because they’re fairly low in calories compared to other brownie recipes. And, this is because they’re not as dense or fudgy. They’re light and airy, which I love!

When making these healthy brownies, I like to use a 9×13 baking dish. If you cut these brownies into 24 squares, then each square comes out to about 100 calories each. And, at 24 squares, they’re the perfect size for a healthy snack. Also, the kids will love them too!

Keep in mind that each brownie bite is 100 calories per square for the base recipe (no added toppings). But, don’t worry, their still super delicious even without the added toppings!

How to make healthy brownies

Of course, there are many ways to make healthy brownies. Some recipes call for flours, such as almond flour, coconut flour, etc. But, today’s brownie recipe is flourless. Instead, we’ll be using bananas and nut butter as our base.

Here’s how to make these healthy brownies:

  • Mash Bananas: Using 3 medium-large ripe bananas, mash with a fork. To get the best texture, use a handheld immersion blender to further puree the bananas (makes a big difference!)
  • Add Nut Butter: Once the bananas are pureed, add in any type of unsweetened nut butter. I prefer almond butter or peanut butter. Mix into the pureed bananas.
  • Add all remaining ingredients: Add all other ingredients and mix until fully combined.
  • Bake: Pour brownie mixture into a greased or lined 9×13 baking dish. Add (optional) toppings). Bake for 30-35 minutes at 350 degrees F.
  • Cool and Slice: Let brownies cool completely before slicing. Store in fridge for up to 7 days and ENJOY!

As you can see, these healthy brownies are super easy to make and are the perfect healthy snack to work into your meal prep routine. Plus, I guarantee they’ll curb your sweet and chocolate cravings!

How to customize flavors for these healthy brownies

Today, I’m sharing the base recipe for these flourless protein brownies. But, they’re super flexible, which means you can get creative with toppings and other add-ins.

Feel free to add in things like:

  • Chopped Nuts for an extra crunch
  • Unsweetened Shredded Coconut
  • Chocolate Chips or Cacao Nibs
  • Drizzle Nut Butter over the top

Personally, I love adding in chopped walnuts and chocolate chips or cacao nibs over top. But, keep in mind, that each square contains 100 calories without the add-ins.

  1. Hey Kayla! I just found you today and I’m so so excited to check out the rest of your blog! For the brownies, I can’t have egg- any subs you think would work? Thanks and have a great day!!

  2. Monica Ramirez

    Hi Kayla! Can these be frozen?

  3. CanadaMom

    My little ones LOVE these. I make them a lot!

  4. Theses taste more like chocolate cake. I doubled the cocoa and added chopped 100% chocolate bar, Lindt, about 2/3 of the bar. I suggest omitting the egg.

  5. These are my favorite brownies! I like more of a light, fluffy brownie so these were perfect for me. So easy to make & curbs my sweet tooth craving!

  6. How much collagen? It would help a lot if you used grams for weight. A scoop doesn’t mean the same thing with different brands. Thank you so much. Same for bananas. How much mashed banana or how many grams. thanks

  7. These are the best brownies ever! I constantly make them and have them on hand for me and my two year old. Love that they are grain free and have collagen!
    Thanks for your amazing recipes <3
