Spent Grain Dog Treats – the best way to use up spent grain!

In my search for something to do with  all  the spent grains from my home brewing , I came across an idea that conveniently (and quite happily!) linked my love beer making to my love of dogs: spent grain makes great treats for your dog!

MacDuff, our lovable Scottish Terrier–who’s hobby is to eat–always needs treats to help train him… he is, as they say, a “food motivated dog.”  A lot of treats are needed to hold his interest, and unfortunately, not all dog treats are healthy for a dog.  This recipe makes a biscuit that is a cheap and healthy alternative to rewarding your dog for a job well done.  MacDuff loves them so much, his emergency word to get his attention quickly is “biscuit”!

Spent grain, peanut butter, flour and eggs are all the ingredients you need to make these easy dog treats. Please remember that hops are toxic to dogs, SO DO NOT MAKE THESE BISCUITS if you’ve mashed with hops!

Recipe for the Treats



4 cups spent grain
2 cups flour
1 cup peanut butter
2 eggs
Fruit such as banana or blueberry (optional)



  1. Pre-heat your oven to 350 F.
  2. Mix all ingredients together with hands to make a dough ball.
  3. Roll out the ball on a floured surface until the “dough” is a 1/4″ thick.
  4. Grab a cookie cutter and cut out as many treats as you can, putting them on a cookie sheet as you go.
  5. Bake for 30 minutes in the 350 F oven,
  6. Turn the temperature down to 225 F and bake for an additional 2 hours. This last step will ensure you dehydrate the biscuit increasing the shelf life – 2 weeks in an airtight container, or a few months in the freezer.
