Protein cookies have the sweetness and chewy texture of traditional cookies, but with the healthy benefits of added protein! Protein usually replaces some of the flours used in other cookie recipes. You can find a variety of ingredients in these cookie recipes, including honey, raisins, oats, or coconut sugar. For this rich and chocolaty recipe, we're using one of my very favorite protein sources -- bone broth protein -- and keeping it keto friendly with nut butter and a keto approved sweetener. The collagen makes a great stand-in for gluten to make them soft and chewy!
