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 replace the banana with something else? like apple sauce
Yes, applesauce works great as well. Hope the pup enjoys.
Do you cook the oatmeal first?
There is no need to cook the oatmeal first Brenda!
Hi there! Can these be frozen?
Hi Danielle! Yes, these can be frozen for up to 3 months--just be sure to defrost BEFORE you give to your dog 🙂
I made my husband oatmeal raisin cookies today and, as always, our 3 pooches must sample a little of whatever it is we are eating. So, I searched for a pet-safe oatmeal cookie and found this one. The batter made exactly 12 cookies and we are all waiting with anticipation the final result. They smell quite delicious! Baked them up for 16 minutes and they are delicious! The dogs love them and they are awesome in their simplicity, I think next time, I will add some cinnamon (safe for dogs) for a little zip. Thank you for this simple and simply delicious recipe. You have made Genesis, Exodus and Luke very happy. Mommy & Daddy too!
Oh how sweet!! I am so glad your puppies are all very happy 🙂
I just made these for my 100lb Boxita. He absolutely loved them. Thanks for sharing this recipe. I have been looking for a healthy treat for my big baby. I love knowing what is in the food he eats.
Oh I am so glad your dog enjoyed them 🙂
So glad I got to meet Bailey! I would have loved to share one of these cookies with her! Thanks for including Bailey in Saucy Saturdays too!
Bailey loved meeting you all too 🙂
