Peanut Butter Dog Cookies are an easy homemade dog treat made with just four simple ingredients. Unlike traditional dog biscuits, there is no flour to measure or dough to roll and cut. Simply mix, scoop, flatten, and bake for soft, slightly chewy dog cookies in about 15 minutes
I originally started making these simple peanut butter dog treats for our Boston Terrier, Bailey, and my kids quickly dubbed them dog cookies. They remain one of the easiest ways to make a homemade dog treat, especially when you already have a ripe banana sitting on the counter.

- Just 4 Ingredients: Rolled oats, banana, egg, and peanut butter
- Easy to Make: No flour, rolling, or cookie cutters required
Kristen's Key Tips for Dog Cookies

Making these homemade dog treats is incredibly easy, but there are a few important things to keep in mind.
- Check the peanut butter label. Never use peanut butter containing xylitol, sometimes labeled as birch sugar, which is toxic to dogs.
- If your dog has allergies or health concerns, check with your veterinarian before introducing a new treat.
- Use a ripe banana. A soft, spotty banana is easier to mash and blends more evenly into the batter.
- Use rolled oats for the intended texture. As written, these cookies are softer than traditional dog biscuits but still have a bit of chew. For a softer, finer texture, pulse the oats into oat flour and follow the mold variation in the recipe notes.
- Flatten the cookies before baking. The oat mixture is similar to my Banana Breakfast Cookie and doesn't spread like traditional cookie dough, so gently flatten each scoop with a fork for more even baking.

How to Make Dog Cookies
- Prepare batter. In a medium bowl, whisk the egg. Add the banana and peanut butter, then mash with a fork to combine evenly. Stir in the oats. The mixture will be thick and slightly sticky.

- Portion out cookies. Scoop the batter into 1-tablespoon portions onto a parchment-lined baking sheet. Flatten slightly with a fork so the cookies bake evenly.

- Bake. Bake for 10-12 minutes, or until the treats are set and lightly golden on the bottom.
- Cool completely. Let the cookies cool completely before serving or storing.

How to Store Dog Cookies
- At Room Temperature: Once fully cooled, transfer to an airtight container and store for 3 days. If your kitchen runs warm, refrigeration is the safer option.
- In the Refrigerator: Store fully cooled cookies in an airtight container for up to 7 days.
- In the Freezer: Flash freeze the cooled cookies on a baking sheet for 30-60 minutes, then transfer to a freezer-safe bag or container and freeze for up to 3 months. Thaw in the refrigerator or at room temperature before serving.

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.
