It’s no secret I love cookie dough. The cookie dough obsession started with my viral healthy 4-ingredient cookie dough bark, then spiraled into an edible cottage cheese cookie dough and healthy cookie dough date bites. So up next in our cookie dough lineup are these seriously delicious collagen cookie dough protein bars. Made in just one bowl, with 7 simple ingredients – they’re totally gluten-free, dairy-free, and pack 15 grams of protein per bar! I’ve truly never found a protein bar recipe with cleaner ingredients than this one right here. I love meal prepping a double batch of these homemade protein bars, freezing half, then enjoying the other half as an afternoon protein snack all week long. So simple, healthy, and truly delicious!

Frequently Asked Questions

What collagen powder did you use?
I used Vital Proteins Collagen Powder, but Further Foods Collagen works just as well. Any unflavored collagen powder will work here without affecting the taste or texture.

Can I use a different nut or seed butter?
Yes! Cashew butter makes these bars extra creamy, but peanut butter works great too. For a nut-free option, sunflower seed butter is a solid substitute – just note it may slightly change the flavor.

How much protein is in each bar?
Each bar contains about 15 grams of protein, primarily from the collagen powder and nut butter, making them a great high-protein snack option!

Storage Tips

Store these cookie dough protein bars in an airtight container in the refrigerator for up to 1 week. For longer storage, keep them in the freezer for up to 2 months and let them thaw for a few minutes before enjoying. They’re best served chilled for that classic cookie dough texture.
