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.

Peanut Butter Dog Cookies at a Glance
- Yield: 12 soft dog treats
- Time Needed: Ready in 15 minutes
- 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.
Happy Cooking! xo Kristen
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.

Awesome, going to make for our miniature Pinscher/Pug's 16th Birthday.
Happy Birthday to your fur baby!
made these. They took 10 min to make, are super simple, but only make 12 and they are soft-> good for dogs with bad or missing teeth. But I prefer crunchier treats for my dogs. These are certainly nutritious. It would be very simple to double the recipe.
I baked for 15 minutes and the outside was crunchy after cooling
Hi, I would love to make this recipe. But, we are having some oven problems so can these be cooked in the microwave? If so how long?
Hi Hammy! I am sorry for your oven issues. I have no experience baking these in the microwave. I would suggest omitting the eggs and making them a no-bake treat for your dog.
There is really no reason to cook these at all. I've fed every dog I've owned (9) raw food only. They all lived past their breed's predicted life span (even I'm shocked by that fact). A raw egg isn't going to hurt fido, in fact, it's better for him. Baking them might make them easier to handle or look cuter to us humans but that's all.
Can I substitute unsweetened applesauce for the banana?
I would start with 1/4 cup of applesauce and add more as needed. I hope your pups enjoy.
This is an awesome healthy recipe for my dog Jack. Thanks! I like to make things in larger quantities. Can these be frozen? If so, how long will they last? I think they will make really good Christmas gifts too.
Hi Tonya! So glad Jack likes them! These can be frozen for up to 3 months 🙂
I have been making this recipe for over a year now and IT IS STILL A HIT! My babies have definitely gained weight because I make the recipe times 4 and we give them way too many but they just love them SO much and how can you deny their sweet little faces!!!!! Jusy fyi, a ton of other factors play into their weight; for example, Maxi has Addison's disease so he is always hungry due to taking steroids every day; Gumbo has allergies so there are not many treats we CAN give him for a long period of time; and we started giving them wet food because they have gotten older.
As long as you portion correctly per your Babies' weight and do not spoil the crap out of your Babies like we do, they won't gain weight solely due to this treat.
Sissy and Braxi gave this recipe a thumbs up ALSO!! (:
I have even snacked on many (;
Excellent Results and I added a little Full Spectrum Hemp oil for my old retriever.
Thanks for the help!
