Quick and Easy Spent Grain Dog Treats Recipe

When you switch from extract to all grain brewing, you will likely find yourself wondering what to do with all of that spent grain leftover from your brew day. Sure, you could throw it away, but it seems like such a waste! There are a lot of great things you can do with spent grain (like our FAVORITE spent grain pizza dough or these amazing spent grain beer crackers or spent grain pudding cookies!), but why not use some leftover grain to make some treats for your four-legged friends? Spent grain dog treats are easy to make and are a great way to share your brew day with your favorite furry assistant brewer!

Spent Grain Dog Treats Recipe


(We have been using Amazon Fresh deliveries to avoid the supermarket during COVID-19)

  • 2.5 cups of Spent Grain (wet, but squeezed slightly to let some of the moisture out)
  • 1.5 cups of All-Purpose Flour
  • 2 Large Eggs
  • 1/2 cup Natural Peanut Butter
    • NOTE: Make sure you get a natural peanut butter with just peanuts and salt as ingredients. Some brands of peanut butter contain Xylitol, which is extremely toxic to dogs.


 dog treats.
  1. Add all of the ingredients into a large mixing bowl and mix well.
  2. Using a rubber spatula, transfer mixed batter onto a cutting board and flatten the mixture to about 1/3″ thick. You can use a rolling pin if needed, but I found it easier to do with my hands.
  3. Use a fun cookie cutter to cut the treats into shapes, or just cut it into squares with a knife.
  4. Place cut treats onto a lightly greased cookie sheet.
  5. Bake at 350°F for 30 minutes.
  6. Reduce temperature to 200°F and bake for about 2 more hours, checking every 20 minutes or so to make sure the treats are completely dried out.
  7. Once the treats are completely dry, remove and allow them to cool.
  8. Store the treats in sealed bags in the refrigerator. I split the batch of treats into several smaller bags and keep most of them in the freezer with one bag in the refrigerator at a time.
  9. Grab a homebrew, give a treat to your four-legged friend, and enjoy!
