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.

Hi so sometimes I am out of bananas and I was wondering what can be a replacement for the bananas in this recipe
You can use 1/2 cup of unsweetened applesauce.
Ok thank you this was one of the best dog treats like as soon as I grab the bag my dogs come running lol
Wonderful! Love hearing you pups enjoyed
I also added pumpkin 🎃
Just made these for my pups and they absolutely loved them. Super easy recipe! Thank you.
You bet! So happy to hear your pup enjoyed them!
Made these treats for Christmas gifts for my baby bear and his cousins and they absolutely loved it, including my granddaughter🥰
Wonderful! Thanks for sharing!
I used to make these for Finn. Drool city when I went for the box. I did taste them for quality control.
My goldendoodle loved these. And they were so easy to make. Thank you!
Awesome! Thanks for sharing!
can these treats be frozen?
Yes! Once cooled, store them in an airtight container for up to 3 months. Just defrost fully before serinvg so not too hard for your pup!
Easy to make and shape with a cookie cutter too!
I love that these are healthy for my Lola girl, my daughter loved making them and Lola loved eating them! Thank you...absolutely amazing 😍
Does it have to be an overripe banana, or would a regular ripe one work?
As long as it is ripe enough to smash easily, it will be perfect!
Okay, I added shredded carrots. About a half cup. And I increased the peanut butter. Next batch will get pumpkin about a half aa cup and I'll increase the oats. That will be on site so i don't know how much yet. All i know is puddin will love them. I'm been making her just pumpkin and peanut butter treats. I was going to add the carrots to them but I added flaxseed instead. That works for her too. She does like it in her treats. We leave home everyday for long walks. She tells me when she's good for a treat. My pocket is emptied before i get back to the car. I leave some in the glove compartment because of the pocket being emptied. We do three miles a day so that's a lot of treats. Thanks for this one.
