I regularly bake horse cookies for my horses. Usually I use a little heart cookie cutter and cut about 200 cookies out of dough and the horses love them. But the all time favorite, never refused, always begging for more Nickers N Neighs. Yup, they are named for the exact reason of when the horses know these treats are coming they nicker and neigh every time without fail.
I don't care, apples and carrots got nothin' on this recipe. They often crumble apart but the horses don't care one bit.
Indigo's Nickers n' Neighs
1cup oatmeal or bran
1cup flour, preferably whole wheat
1/2 cup diced apples (as small as you can get them without chopping fingers. Don't shred them they don't have the same effect. Leave the peels on)
2 tsp of desired oil (sunflower, flax, wheat germ, vegetable etc...)
1/4 cup molasses
Mix dry then wet ingredients and then apple chunks. Make into little balls. Preheat 350 and bake for 15 minutes. Serve to your favorite nicker or neigh, preferably still warm but they still like them a few days after. They don't have a very long shelf life compared to my other cookies, so I usually make them and give them to the horses warm and don't worry about them molding. They absolutely love them, will take them over a fresh apple any day. Oh and cows also like them lol! I used to get the whole herd of heifers at the gate when they knew the horses were getting them.
