Peanut Butter Dog Cookies are the perfect wholesome, homemade treat for your pup. Made with just oats, banana, peanut butter, and egg, these simple dog treats come together in minutes and are loved by dogs of all shapes and sizes.
If your dog is part of the family (and mine absolutely is), you will love spoiling them with these dog cookies and my dog birthday cake. Both use pantry staples and come together with minimal effort.

Key Tips to Know Before Starting
Before you grab a bowl, here are a few small details that make these treats turn out just right for your four-legged friend.
- Always check with your veterinarian before introducing new foods, especially if your dog has allergies or health concerns.
- Choose natural peanut butter. Make sure it does not contain xylitol which is toxic to dogs. I prefer using natural peanut butter without added sugar or oils, but it is always best to read the label.
- Use ripe banana. A soft, spotty banana mashes easily into the other ingredients.
- Cool completely before storing in the fridge. Trapped steam can make the dog cookies quickly grow mold. Once cooled, store in the refrigerator where they will last up to a week.
How to Make Homemade Dog Cookies
Mix, scoop, bake! It is so easy to make these peanut butter dog cookies!
Step One: Prepare Batter
In a medium bowl, whisk the egg. Add in the banana and peanut butter and mash together until evenly incorporated. Add the oats and mix until combined. The mixture will be thick and slightly sticky, like my banana breakfast cookies.

Step Two: Scoop
Scoop 1 tablespoon batter out onto baking sheet, lined with silicone mat or parchment paper. Flatten slightly with a fork, so that they will bake evenly.

Step Three: Bake
Bake for 10-12 minutes, or until the treats are set and lightly golden on the bottom.
Let the cookies cool completely and then let your pup enjoy!

Storage Tip
Once cooled fully, store the dog cookies in an airtight container at room temperature for up to 5 days, or in the refrigerator for up to 7 days. If your kitchen runs warm, refrigeration is the safer option.
You can also freeze the treats in an airtight container for up to 3 months. Thaw at room temperature before serving.
Homemade dog treats are such a small thing, but they feel special. And when your dog looks at you like you just handed them the greatest gift on earth, it makes the 15 minutes in the kitchen completely worth it.

Can I leave out the banana.
I have oats and peanut butter and egg..but no banana.
Thanks
Hi Renee! I am sure your dog won't complain about there being no bananas, but you likely will need additional peanut butter or applesauce to hold the treats together.
Can these be frozen?
Absolutely! Allow the treats to cool, place them in an airtight freezer-safe container and store them in the freezer for up to 3 months. Pull a treat or two out at a time and let fully defrost at room temperature or in the refrigerator before allowing your dog to enjoy.
We ran out of training treats for our puppy and the weather has kept us from really going anywhere for the past few days so I made these. He loves them, I made them super small, he actually likes them more than the meat treats I get at the pet supply store.
I love hearing your sweet puppy enjoys these! Thanks for sharing. Stay safe and warm!
My dogs love them! Thanks for the recipe!!
My Jack Russell, Kirby, turns 16 today!!
I wondered if these bake to a softer cookie? Or is there a soft batch version as he has minimal teeth?
Thanks!
Hi Shelly! These are on the softer side. I would recommend cooking for a 1-2 minutes less for him to enjoy a softer treat. Happy Birthday to your pup!
Can you use sweet potato in these biscuits, how fattening are they
Hi Patricia! Feel free to use mashed sweet potato in place of the banana or half of each. As for nutrition, it is provided in the recipe card.
Can you use this recipe without banana
Hi Holley! Yes! Feel free to use applesauce, pumpkin puree or plain yogurt in place of the banana.
