I found an awesome horse cookie recipe. Even my picky eaters love them!
Here it is! (I did steal this from another site, but made some alterations)
1 cup oatmeal
1 cup flour
1.5 TBS sugar
1.5 TBS salt
1(or so)cup diced carrots
2 TBS oil (any kind of cooking oil)
3/4 cup water
1/4 cup molasses
Mix together and make small balls. (Dough should be VERY, VERY sticky!) Bake at 350*F for 15 minutes of until brown on the edges.
