Finding a good protein snack can be HARD!

I mean essentially when shopping for protein products you immediately think they are all healthy. They are in “that” section, right? WRONG! 

We all know that anything that comes in a package has been processed, while some are better than others, you really have to read the labels.

Most store-bought bars, cookies, and snacks are full of added sugar and carbs, in relation to the amount of protein they offer, they aren’t even healthy anymore! 

Long story short, I really like making my own!

My version of homemade chocolate protein brownies are great for an on the go breakfast, can be made in batches, and are freezer friendly!

Ingredients for Chocolate Protein Brownies

Bananas – Make sure these are overripe! The riper they are, the more sweetness they offer!

This is how we are going to keep our brownies moist and delicious without having to add any other sugar.

If you don’t like bananas you can swap them for sweet potato!

Flour – I am using oat flour but you can swap it out for almond flour if that’s what you have, just use the same amount that is listed in the recipe card. 

Nut Butter – Choose your favorite! Just be sure it’s natural.

The label should list the nuts and possible salt, but that should be it!

If you are going with peanut butter I HIGHLY recommend Trader Joe’s, theirs has the perfect ratio of peanuts to salt! Love Trader Joes? Check out my grocery haul for more must-haves!

Cocoa Powder – My favorite brand is 365 by Whole Foods Market!

It’s organic and you can get it from Amazon without even leaving your house! Winning!

Protein Powder –  You can use vanilla or chocolate protein. If you are a chocolate lover like me, go with the chocolate protein

Chocolate ChipsLily’s is one of the best chocolate companies! Her chocolate products are as whole as you can get.

They have dairy-free options and all are non-gmo! 

Salt and Vanilla Extract

Best Protein for Brownies

There isn’t really “a best protein” for brownies, but I can say that a plant-based protein is much better than a whey-based one.

With that being said, one of my favorites is Orgain

It tastes and smells like a dessert and if you have ever smelled other protein powders you will thank me!

They also have tons of flavors and premade shakes to take on the go as well!

How To Store and Freeze Chocolate Protein Brownies 

To Store

Once the brownies have cooled completely, store them in an airtight container, and keep them in the refrigerator for up to 5 days. 

Freezing Instructions

Let the brownies cool off (completely) then place them in a single layer in a freezer bag or use a vacuum sealer.

If you want to store more than just a single layer, place a layer of parchment paper in between so they don’t stick together. 

When you are ready, you can reheat them in the microwave or let them thaw at room temperature. 

If you are meal prepping, freezing them is a good idea, because you can throw it in your lunch box and it will be ready to eat by snack time.

Use sunflower seed butter instead of nut butter. It can be used at a 1:1 ratio.

I would not add protein powder direclty to a box brownie mix. The batter will be too thick and dry.

You need to delicately balance protein powder with the other dry and wet ingredients.

  1. I tried this recipe because I had protein powder I wanted to use up. It cost a lot but the texture is too gritty to manage in liquid form and I wanted to mix it into some baked goods instead. The brownies were surprisingly tasty and fudgy for such a “healthy” recipe. My diabetic Dad actually liked them. Baking them for 40 minutes would have ruined them, however. Mine were ready after 25 minutes and the recipe seems too small IMO to bake a full 40 minutes without resulting in cardboard brownies.

  2. i wanna do these protein brownies but don’t know big the size of the pan should be. Can tell me it please ?
    Thank u

    Thank you for the yummy, easy recipe! But I am wondering if these measurements can be used for a 9 x 13 pan, or if they need to be modified?

    1. Hi! I have only made the recipe as listed but I would definitely adjust the measurements to match the 9×13 pan size if you want the same level of thickness. Otherwise, your brownies will be very thin!
