Rocky's Beer Dog Cookies
(Simi Valley, CA USA)
As a home brewer I try to minimize my waste by products. So the grain used to make my beer gets reused for dog treats.
4 cups spent grain (grain left over from home brewed beer)
4 cups flour
1 cup peanut butter
Mix together (works well with hands) and roll onto cookie sheet. Score (almost through) into shapes you want, or use a cookie cutter as you would for cookies. They don't spread out and they pretty much end up the thickness you start with. This recipe made one cookie sheet but they are pretty thick so you could adjust that if you want them thinner.
They end up very crisp after they've been baked and dried. Bake at 350 for 30 min. Let cool enough to break them up then place back in the oven to dry for 8-10 hours at 225. You want to make sure they dry adequately, if they look like a fig newton when you break one they're not dry. If they don't dry enough they will mold. Dried thoroughly they will store well in an airtight container.
