Crunchy Homemade Peanut Butter and Banana Dog Treats Recipe

June 03, 2022

We previously made these cookies and offered them for sale online as well as our brick-and-mortar store. People, as well as their beloved dogs, absolutely loved them. One of the best things about these homemade dog treats is that by following the directions below, they will have a much longer shelf life than most "homemade" dog treats. As a matter of fact, we never had even one cookie go bad. Of course, that could also be owed to the fact that they sold as fast as we could make them! But honestly, they will last for a month, or more, if you get them dried out completely. 

We worked really hard on these recipes to create a crunchy, healthy, delicious dog treat for our own dogs, then it expanded into selling them, and now we would like to share our recipes and secrets with you so that you can make your own treats!  The recipe below is one of many that we will be posting in the future. All of them share 3 key instructions that must be followed in order for these recipes to be successful, 1. Oat flour. No other flour will work. 2. Drying. The cookies must be left in the warm oven overnight at the very least to thoroughly dry. 3. Size consistency. Be sure to roll your dough to 1/4" thickness. Too thick and the cookies will not dry all the way through.

Okay, with those instructions in mind, here's the first recipe: 

Peanut Butter & Banana Dog Treats


2 ½ cups oat flour
½ cup warm water
2 eggs
3 Tbs. smooth peanut butter
1 small ripe banana, smashed up with a fork

¾ cup rolled oats 
2 eggs, beaten


Preheat oven to 350 degrees. 

  1. In mixing bowl, add water and egg, beat vigorously with a whisk until frothy. Add peanut butter and banana, stir until smooth. Add flour and stir until well blended. Rest dough in refrigerator for at least 1 hour.
  2. Remove dough from fridge and add 3 quick shots of hot water from faucet to help warm the dough. Stir (you may need to use your hands because the dough will be very stiff.) Add a little more flour if too soupy.
  3. Turn out on floured surface and knead dough until it becomes a well formed, non-sticky ball; add more flour as needed. 
  4. Roll out dough to 1/4 inch thick. Cut into desired shapes with a cookie cutter.
  5. Arrange onto cookie sheet without edges touching or overlapping. Brush cookies with egg wash then sprinkle with rolled oats, evenly.
  6. Bake for 25 minutes, then turn the oven off.  Turn on the oven light and leave the treats in the warm oven overnight (at least 8 hours).

Store treats in an air-tight container in a cool, dry place. We hope your dogs enjoy these as much as we enjoyed creating them!
