I have long awaited to make something with my spent grain from homebrewing. We recently made a rye red and was able to use some of the grain to make some dog treats!
Ingredients:
4 cups spent grain
2 cups AP flour
1 cup peanut butter (all natural)
2 eggs
Directions:
1. Mix all ingredients thoroughly in a large bowl with a wooden spoon.
2. Press cookies down to almost a 1/4 inch and then cut a shape out of them.
3. Put the cookies into a pre-heated oven of 350 degrees.
4. Cook for about 45 mins.
5. Turn off oven for 30 mins and then heat again for 2 hours at 225.
6. Turn off oven and let sit in oven overnight or for 2-3 hours. This helps the cookies get completely dried-out so they don’t get moldy. If the cookies don’t have a hearty snap to them they are not dry enough.
My two long-haired doxies loved these cookies! Let me know if you make any if you add any variations to it. Enjoy!

This is great! Pinning this to remind me to make these for our dog when we start brewing next month or so! 🙂

Thanks! Homebrewing is really fun and rewarding. Let me know what beers you make and don’t be afraid to get creative 🙂
Thanks, I will! We are really excited to start. 🙂
Great idea Jess! Haha, I need to let my brother in law know about this, as he’s the home brewer in our family (I just get to sample the goods, mmm! And now I reckon I’ll steal his spent grain too). This may be a stupid question as I’m not a home brewer, but does the spent grain have any residual alcohol content, or is it taken out before it ferments properly? Just wondering whether the cookies should be rationed with our family’s 2 year old boxer (and his minion, a teeny dragon pup aka maltese cross)! Looking forward to a bake-up!
Hi Laura! No alcohol in the grain. The boiled grain water or “wort” ferments with yeast for a few weeks to make it alcoholic so you are good to go.
Aah, cool. Good to know Jess! Thanks!
