Ingredients and What They Bring to the Cookies
You only need four ingredients for these oat cookies for dogs, and each one brings something tasty and nutritious:
- Old Fashioned Oats – A great source of fiber and a gentle grain for dogs that support digestion.
- Banana – Adds natural sweetness and moisture, plus it’s packed with potassium and vitamins.
- Peanut Butter – A favorite flavor for dogs and a good source of protein and healthy fats.
- Egg – Helps bind everything together and adds a little protein boost.

Ingredient Notes and Substitutions
When making these cookies, there are a few important things to keep in mind and easy swaps you can make:
- No xylitol – Never use peanut butter that contains xylitol. It’s toxic to dogs. Always double-check the label.
- Nut butter swaps – You can use almond butter or sunflower seed butter instead of peanut butter. Just make sure it’s unsweetened and xylitol-free.
- Banana alternatives – No banana on hand? Use ½ cup of pumpkin puree or mashed sweet potato instead.
- Need an egg-free option? Use a flax egg instead. Mix 1 tablespoon of ground flaxseed with 3 tablespoons of water, then let it sit for 10 minutes.
How to Make Oatmeal Cookies for Dogs
Making these homemade dog oatmeal cookies is super easy. Here’s how to do it:
- Preheat your oven to 350°F and line a baking sheet with parchment paper or a silicone baking mat.
- In a medium bowl, mash the banana with a fork.
- Add the peanut butter and egg, and mix until everything is well combined.
- Stir in the oats until you have a thick cookie dough.
- Scoop out about a tablespoon of dough, roll it in your hands, and press it into a cookie shape. Place it on the baking sheet.
- Repeat with the rest of the dough.
- Bake the cookies for 8 to 10 minutes, until they’re set and lightly golden on the bottom.
- Let them cool completely before serving.
You can make the cookies bigger or smaller depending on your pup’s size and needs. Just remember to adjust the baking time; less time for smaller cookies, a little more for bigger ones.

How to Store the Cookies and How Long They Last
Store the cookies in an airtight container at room temperature for up to 1 week.
For longer storage, freeze the cookies in a freezer-safe container or bag for up to 4 months.
Can people eat these oatmeal cookies?
Yes, they’re safe for people to eat! The ingredients are all human-grade and wholesome. Just don’t expect them to taste as sweet as a regular oatmeal cookie. But they’re great for people watching their sugar intake.

Notes
Nutrition
Serving Amount
Treats should make up no more than 10% of your dog’s daily calories. If you’re not sure how many to give, it’s always a good idea to check with your vet.
And if it’s your dog’s first time trying any of these ingredients, start with a small piece to make sure there are no sensitivities or reactions.
Can I substitute egg for unsweetened applesauce
The cookies would be very dense if you use applesauce instead of an egg because eggs act as a leavener.
How long do the keep?
They will last up to 1 week at room temperature or you can freeze them for up to 4 months.
Are these soft enough to put medications in?
I don’t think they would work well for putting medications in, even if they were underbaked. I suggest trying either of these treats that aren’t baked:
