Unbelievably soft Collagen Cookie Bars with the sweetness and peanut butter flavor, but healthy sugar free and low fat! With no protein powder, these cookie bars get the high protein from collagen peptides powder and use monkfruit and peanut butter powder for the goodness!

I was actually going for the thick fudgy and dense protein cookie bars, but this was just something of its own!

And what a magical nutrition label here! Sugar free and low fat in spite of the perfect sweetness and peanut butter flavor!

I used Lakanto’s Golden Sweetener (1:1 sugar-free sugar substitute made with monk fruit) for the sweetness. It actually works as a perfect sub for baking!

And also the sugar free chocolate chips and peanut butter powder (that’s what gives the low fat part).

How to use collagen powder in baking?

Using collagen powder in baking can get a bit tricky because it doesn’t work 1:1 with flour; Collagen peptides powder has a very different consistency as compared to flour or other products, and dessert or baking recipes that call for collagen are usually designed specifically for this ingredient.

That said, it is actually extremely easy to use collagen powder in baking, and it really does produce light, fluffy and soft baked goods – just be sure to follow the recipe and use the approved options for othe wraps.

How to make Collagen Powder Cookie Bars with no Protein Powder?

This recipe for chocolate chip collagen cookie bars is extremely easy to make; just mix and bake!

Here’s what it takes:

Preheat your oven to 350°F and line a baking pan (about 8”) with parchment paper.

Whisk all the dry ingredients in bowl: collagen protein powder, Lakanto golden sweetener, coconut flour, gluten free baking flour, peanut butter powder and baking soda.

Whisk the wet ingredients in a large bowl: Peanut butter, almond milk Greek Yogurt, egg whites and vanilla.

Add the dry mix to the wet and gently fold to combin; Be gentle
You should have a slightly runny batter. (Taste batter and add more sweetener if you want it sweeter).

Add in some of the chocolate chips and fold again.

Transfer the no sugar cookie bar batter into pan, top with chocolate chips and bake for about 25-30 minutes.

How to know when collagen peptides cookie bars are ready?

Baked collagen peptides cookie cars are ready when the top is completely set and dry, and a tester (toothpick or thin sharp knife) comes out mostly dry.

For extra fudgy chocolate chip collagen cookie bars, let some moisture be there on the tester – this should be at about 25 minutes.

Wait until cool!

Don’t cut too soon or they will be too soft.

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.

Alternatives for Healthy Protein Cookie Bars without Protein Powder

For the perfect fudgy and moist protein collagen powder cookie bars, I would highly suggest using the ingredients and brands I recommended; I do have some alternatives you can try. I haven’t testing them all, so I can’t say how your recipe might turn out.

1:1 Gluten Free Baking Flour: All purpose flour or Whole Wheat Pastry Flour, in the same amount by weight.
Lakanto Golden Sweetener: Lakanto white monkfruit sweetener. If not, regular confectioners sugar or coconut sugar (this won’t be sugar free though, and also higher in calories)
Peanut Butter Powder: Regular peanut butter, but reduce milk to 2 Tbsp.
Peanut Butter: Almond Butter, Cashew Butter, or any nut or seed butter.
Greek Yogurt: Coconut Yogurt
Almond Milk: Any other milk
