There are MANy recipes on the web. I have perused many, and found that I put together what I have at the time that is horse edible, and it is easy and fun!
In fact, we had a barn party the other night just to make horse cookies! It was very fun. The ones we made (sorry, I don't measure, plus we made a TON)had sweet feed, mollasses, brown sugar, oatmeal(that I grounds a little in the food processor) ground flax seed. I have added ground carrots, apples or applesauce in the past, but they tend tto be moister and not keep long times.
Look at some recipes and just have fun. I bake mine at about 300, and a convection oven speeds it up immensely.
