I know I’ve already said that my original Collagen Protein Brownies recipe is my hands down favorite, number one healthy protein brownie recipe.

So I just had to adapt that into something more funky; A hint of coffee and a bit of a recipe switch up and this mocha collagen brownie recipe was born.

Ingredients for Mocha Collagen Brownies Recipe

These fudgy mocha collagen brownies are made without protein powder and a few healthy ingredients; No oil, no sugar and gluten free too; The perfect collagen dessert recipe!

Unflavored Collagen Peptides needed for high protein brownies. I use the one from Further Foods (HAYLSKITCHEN gives you a discount)
Unsweetened Cocoa Powder, or Raw Cacao Powder (HAYLSKITCHEN.15OFF to save on Kiva Cacao)
Gluten Free (All Purpose) Baking Flour – or a regular all purpose flour
1:1 Zero Calorie Sugar Substitute – I use Lakanto, to keep this recipe sugar free; (code HAYLSKITCHEN for a discount here)
A bit of Coconut Flour
Instant Coffee
Creamy Peanut Butter
Non-fat Greek Yogurt contributes to the oil-free part of these high protein brownies since it adds the moisture, and also extra protein
Sugar free Maple Syrup for low calorie protein brownie with no sugar!
I use the sugar free monk fruit maple syrup from Lakanto (code HAYLSKITCHEN for the discount here too)
Egg Whites for extra high protein without the added fat from the yolk
Almond Milk or regular milk
Vanilla Extract
Baking Soda

Optionally Chopped Hazelnuts

What can I substitute for collagen powder in baking?

This healthy brownies recipe is designed to be made with collagen powder, and you cannot substitute anything else for it here. Please do not try to use whey protein as a substitute for collagen here, since since they both bake very differently, and your brownies will not turn out the same.

If you want a healthy protein brownie recipe made with protein powder, try my low calorie protein brownies, or this fudgy protein brownie recipe.

Tips for Mocha Protein Brownies without Protein Powder?

This recipe for mocha protein brownies with collagen peptides powder is extremely easy to make; just mix and bake! Here’s some tips to get it right though!

Use room temperature egg whites, milk and yogurt;
This is so the wet ingredients and dry ingredients can mix well.

Room temperature drippy almond butter so it mixes well with the wet ingredients and does not clump.

Whisk dry ingredients well before adding to wet; Coconut flour and cocoa powder could be in lumps.

Taste the batter and see if you need some extra sweetener. I’d recommend using stevia powder to maintain the consistency of the batter and have low sugar collagen protein brownie.

Let brownie cool completely before removing from pan.

Pro Tip!

Use a plastic knife to cut the brownies; these collagen protein brownies are quite fudgy and will stick to a metal knife when cutting.

How to store Coffee Collagen Powder Brownies?

This high protein chocolate coffee collagen brownie recipe keeps well for a meal prep dessert or post workout snack and is freezer friendly too!

Store mocha collagen powder brownies at room temperature in an airtight container for 1-2 days or in the fridge for a week.

To freeze collagen peptides brownies, individually wrap in plastic wrap and place in freezer-safe zipper bags or air tight container; They should keep for 2-3 months.
