Spent grain dog biscuits
4 cups spent grain (do not use grains that have interacted with hops)
4 cups flour
1 cup peanut butter
1 egg
Mix all ingredients together (I used my hands to mash it all up). Spread the mixture out onto a cookie sheet and flatten. Mine turned out a bit dry, powdery, I probably should have added a little water, but the next step is to cut/score into bite size squares. Bake for about half an hour to an hour at 350 F until they are hard.
Remove from the oven and break them apart into separate biscuits, and place them back onto the cookie sheet. Bake them for an additional 8-10 hours at 225 F. This gives them time to really dry out, to prevent mold. Store in an airtight container. These smell pretty good coming out of the oven, but I wasnt brave enough to try one. Maybe Ill serve them up at the next beer gathering I have.
