Spent grain dog treats - Jack

I do my best to compost all my spent homebrew grain, but when the compost pile gets too unwieldy, I’ve had to dump grain in the trash. It’s a sticky, stinky mess.

So I’ve found another way to make use of my spent grains — and it makes my dog Jack and his buddies really happy.

Making dog biscuits out of your spent homebrew grains is an easy way to make snacks for your puppy with ingredients you probably already have in your kitchen.

And while I can’t vouch for how healthy these treats are — similar recipes are all over the Internet — the dogs love them.


2 cups spent grain
1 cup flour
1/2 cup peanut butter
1 egg

The recipe make about two-and-a-half dozen medium-sized biscuits.
