I was wondering if there was a way to add vitamins to my horses homemade cookies? Mostly I want to add biotin to my rescue horses cookies but im not sure if I bake it if the vitamin will still work :/ It would be great to make my own cookies with vitamins for my horses! And I could have a few to, haha. Making my own cookies is way cheaper and I would be so happy if I could combine two great things into one. Anyone else ever tried it? Let me know! Thanks!
