Vegan Peanut Butter & Oat Cookies – The Ultimate Nutty Treat for Your Dog!
If your dog can’t get enough peanut butter (who can blame them?), these Vegan Peanut Butter & Oat Cookies will be their new favorite treat!
Not only are these cookies full of that rich, nutty flavor dogs go nuts for (pun intended), but they’re also easy on the tummy, gentle on digestion, and packed with fiber. Best part? You’ll only need a few simple ingredients to whip up a batch that’s both healthy and tail-waggingly good.
Let’s get into it, shall we?
Ingredients: Only the Best for Your Pup

These simple ingredients combine to make a treat that’s healthy, wholesome, and super tasty for your dog:
- 1 cup rolled oats – High in fiber and easy on digestion. Oats make a gentle base for sensitive doggy stomachs.
- 1/2 cup natural peanut butter – Dogs live for peanut butter! It’s packed with protein and healthy fats, just make sure it’s xylitol-free (that stuff is toxic for dogs).
- 1/2 banana, mashed – Bananas add natural sweetness, potassium, and a little binding power to the cookies.

Set your oven to 350°F (175°C) and line a baking sheet with parchment paper. (Or skip the paper and use a light spray of oil if that’s your jam.) - Mash the Banana
Grab a small bowl, throw in that half-banana, and mash it until smooth. You want it to be almost paste-like. - Combine Ingredients
In a large mixing bowl, combine the oats, mashed banana, and peanut butter. Mix until everything comes together into a thick, sticky dough. If it feels a little dry, add a splash of water—no biggie. - Shape the Cookies
Scoop up a spoonful of dough, roll it into a small ball, and flatten it on the baking sheet to make a cookie shape. Leave a little space between them, but don’t stress—they won’t spread much. - Bake
Bake for 15-20 minutes or until they’re golden brown and firm. Want a crunchier texture? Let them sit in the oven with the heat off for a few extra minutes to dry out. - Cool & Serve
Allow the cookies to cool completely before giving your pup a taste. Trust me; they’ll be sitting nearby, eyes wide, drooling like they’ve never eaten a day in their life.
Can It Be Done in the Air Fryer?
Absolutely! If you’re looking to save some time, the air fryer is a great alternative. Here’s how:
- Preheat your air fryer to 320°F (160°C).
- Place the cookies in a single layer in the air fryer basket (no stacking, please!).
- Bake for about 10-12 minutes. Keep an eye on them as air fryers can vary, and you don’t want crispy cookies turning into doggy rocks.
Air fryer cookies will come out just as delicious but may be slightly crunchier—perfect for pups who like a little extra bite!

Why These Ingredients Are Pure Gold for Dogs

Here’s a quick breakdown of why this treat isn’t just tasty but great for your dog’s health too:
- Oats – These are a gentle fiber source, ideal for dogs with sensitive stomachs. Plus, they’re full of vitamins and minerals, like iron and B vitamins, to keep your pup feeling their best.
- Peanut Butter – Not only does it make your dog really happy, but it’s also loaded with protein and healthy fats. Just be sure it’s xylitol-free (seriously, double-check the label).
- Banana – Bananas are like nature’s little multivitamin, packed with potassium, fiber, and a hint of sweetness. They also help bind the dough without needing eggs.
Storing These Treats: Keep ‘Em Fresh for Longer
Making a batch of these is a breeze, and they store well, so you can have a stash ready for whenever the puppy eyes come out.
In the Fridge
If you plan on using these cookies within a week, pop them in an airtight container and store them in the fridge. They’ll stay nice and fresh without losing their shape or texture. Plus, keeping them in the fridge prevents the peanut butter from getting too soft.
In the Freezer
Want to keep some for later? These cookies freeze like a dream. Once they’re cool, layer them with a bit of parchment paper (so they don’t stick), then put them in a freezer-safe container or bag. When your dog’s in the mood for a treat, pull out a couple and let them thaw for a few minutes.
FAQs
Q: Can I use another type of flour instead of oats?
Sure thing! Rice flour, coconut flour, or even whole wheat flour can work. Just keep an eye on the moisture since different flours absorb liquid differently.
Q: My dog isn’t into peanut butter. What’s a good substitute?
Some dogs aren’t into it (surprising, I know). Try almond butter or sunflower seed butter, just make sure it’s unsweetened and xylitol-free.
Q: Are these treats okay for puppies?
Absolutely! Just go easy on the portion size since puppies have tiny stomachs. It’s always good to introduce new treats gradually.
Q: How many treats can I give my dog per day?
These should be occasional treats, so aim to keep them around 10% of your dog’s daily calories. For smaller dogs, 1-2 treats, and for larger dogs, maybe 3-4, depending on their activity level.
Q: What if my dough seems too sticky?
If the dough is too sticky to handle, add a bit more oat flour or rolled oats. And if it’s too dry, add a splash of water to get it to the right consistency.
