Amazingly fudgy Peanut Butter Chocolate Collagen Bars that are actually healthy! These chocolate collagen protein bars use a ton of collagen powder and egg whites and are sweetened with monkfruit; No sugar!

It’s been a while since I made my collagen protein brownies, and I really wanted something similar.

Revamped that recipe and turned it into these amazing rich and fudgy chocolate peanut butter layered dessert bars; High in protein from the collagen and egg whites, but still healthy and sugar free using monkfruit sweetener.

Not even kidding with the level of fudginess here; My fiancé was just at awe!

Ingredients for Peanut Butter Chocolate Collagen Bars

These extra fudgy chocolate collagen bars are made with a few healthy and simple ingredients. They’ve got no butter or oil or sugar, and really are a macro friendly collagen powder 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
Lakanto’s Golden Sweetener – This is the Golden Monkfruuit 1:1 Sugar Substitute from Lakanto, and keeps this recipe sugar free; (code HAYLSKITCHEN for a discount here)
A bit of Coconut Flour
Creamy Peanut Butter
Non-fat Greek Yogurt contributes to the oil-free part of these chocolate collagen bars
Egg Whites for an extra high protein collagen dessert recipe without the added fat from the yolk
Almond Milk or regular milk
Vanilla Extract
Baking Soda

And for the Low Fat Peanut Butter layer in these Collagen Bar:

Lakanto’s Peanut Butter Powder, also known as Powdered Peanut Butter. I recommend Lakanto for a sugar free version (the code HAYLSKITCHEN gives you a discount)
Or you could use the one from PbFit or PB2 too.
Vanilla Protein Powder– This is the replacement for sugar in these protein sandwich cookies; I used a Whey here from Protein World (code HAYLSKITCHEN gives a discount here too)
Creamy Peanut Butter
Lakanto’s Sugar free Maple Syrup for no-sugar collagen dessert bar
Lakanto maple-flavored syrup is sweetened with monk fruit. (code HAYLSKITCHEN gets you a discount)

Tips to make Chocolate Collagen Powder Bars with no Protein Powder:

This recipe for chocolate protein collagen bars is extremely easy to make, but here’s some tips to get it right.

Grease the baking pan so the chocolate bar layer comes off easily.

Use drippy, creamy peanut butter so that it mixes smoothly with the rest of the wet ingredients, and does not clump.

Whisk the wet ingredients, don’t use a spoon so that everything mixes well; No clumps again.

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 sugar free collagen dessert recipe.

Let the chocolate layer cool completely before topping, or the peanut butter layer will melt away.

Use whey protein powder for the peanut butter layer (not whey-caesin) for the sugar free caramel filling since it works best with these ratios. Add more water if you use whey-caesin.

Extra Tip for cutting collagen dessert bars

Use a plastic knife to cut; These collagen protein bats are quite fudgy and might stick to a metal knife when cutting.

How to Store Homemade Collagen Protein Bars

These chocolate collagen protein bars are a geat homemade snack and can be stored on the counter, in the frige or in the freezer.

Store (cooled) baked chocolate collagen bars in an airtight container on the counter for 2 days, or fridge for 1 week.

To freeze, freeze each piece individually on a baking sheet, and then transfer to freezer-safe zipper bag; Or wrap each piece in plastic wrap and place in freezer-safe zipper bag. They should keep 2-3 months.

Thaw before eating!
