Oat & Peanut Butter Cookies for Dogs

By arsh May 4, 2025

So here’s the deal.

Sometimes you just want to make your dog something good. Like, actually good. Not the plastic-tasting treats from a bag that smell like regret and stale cornmeal.

I’m talking about the kind of treat that makes your dog look at you like, “Wait… you MADE this? For me?” That’s what these cookies are. Just three ingredients, no oven drama, and the kind of recipe that’ll have you wondering why you haven’t been doing this for years.

Let’s jump in.

But before we do, a quick note:

This is not a blog post about baking perfection.
It’s about making something wholesome and tasty for your dog, without a whole afternoon of effort, and without worrying about preservatives, fillers, or whether or not your pup can pronounce “propylene glycol.”

If that’s what you’re after, keep reading.

Why This Recipe Works

It’s simple. Dogs love peanut butter. Dogs love oats. You probably already have those two things sitting in your kitchen right now. And when you mix those together with a little binding magic, you get chewy, hearty treats that even picky eaters will devour.

You don’t need pastry chef skills. You don’t need a rolling pin. You just need to mix, shape, bake, and feel like the best dog parent in the world.

This is the kind of treat that makes tail wags happen faster.


What You’ll Need

Here’s the exact breakdown of what you’ll need to make these.

IngredientAmountNotes
Oat Flour¾ cupYou can grind rolled oats in a blender if you don’t have oat flour
Natural Peanut Butter1 cupMake sure it’s xylitol-free. Read your labels
Egg1 largeHelps bind the dough. Optional, but recommended

That’s it. No sugar. No salt. No fluff.

If you want to make this a little extra, you can throw in a spoonful of unsweetened applesauce or a mashed banana for some natural sweetness. But even without those, this base recipe is a win.


Tools You’ll Use (aka: What to Grab from the Drawer)

  • A mixing bowl (big enough to really stir without oats flying everywhere)
  • A sturdy spoon or spatula
  • A baking sheet
  • Parchment paper (or a silicone baking mat)
  • A fork for pressing those cute cookie tops
  • Optional: food processor or blender if you’re making your own oat flour

No stand mixer. No fancy gadgets. Just kitchen basics.


First Time? Read These Pro Tips

  1. Skip the additives.
    Always use unsweetened, unsalted peanut butter. Xylitol is dangerous for dogs, even in tiny amounts. If the ingredients list on the jar is more than “peanuts,” don’t use it.
  2. Too sticky? Too dry?
    Your dough should be firm but moldable. If it’s too sticky, add a little more oat flour. If it’s dry and crumbly, a small splash of water (or unsweetened applesauce) fixes everything.
  3. Don’t overbake.
    These cookies don’t need to be hard to be good. Aim for a golden bottom, not brown edges. If they’re a little soft when you pull them out, they’ll firm up as they cool.
  4. Cool completely.
    Hot peanut butter can trap heat like a sneaky oven sponge. Always let these cool fully before letting your dog taste test.
  5. Make small cookies.
    Even big dogs do better with smaller bites. Keeps portion control in check and makes storage easier.

Substitutions and Variations

Let’s say you’re short one ingredient. Or maybe you’re just feeling a little creative.

Here are some simple swaps that still work:

IngredientSwap OptionsNotes
Oat FlourAlmond flour, whole wheat flourTexture may change, so adjust liquid as needed
EggFlax egg (1 tbsp flaxseed + 2.5 tbsp water)Great for dogs with egg sensitivities
Peanut ButterCashew butter, almond butterAs long as they’re plain and unsweetened

Want to add some flair?

  • Mix in a little cinnamon (no nutmeg—it’s toxic to dogs).
  • Stir in shredded carrots or apple bits.
  • Top with a little mashed banana before baking.

Just make sure any add-ins are dog-safe and used in small amounts.

Instructions (Let’s Bake)

Alright, here’s how to make these step by step:

  1. Preheat your oven to 350°F and line a baking sheet with parchment paper.
  2. Mix together the oat flour, peanut butter, and egg in a bowl. Stir until fully combined.
  3. Scoop out dough in small spoonfuls and roll into balls. Flatten slightly with your palm or use a fork to make that criss-cross pattern.
  4. Bake for 10–12 minutes. Keep an eye on the bottoms—lightly golden is perfect.
  5. Let them cool completely on the pan or a wire rack before sharing with your pup.

Store them in an airtight container on the counter for a few days or refrigerate for a bit longer freshness.

FAQ

Can I use crunchy peanut butter?
Yes, totally fine. Just make sure it’s natural and xylitol-free.

How do I know if my peanut butter is dog-safe?
Read the label. Avoid added salt, sugar, artificial sweeteners (especially xylitol), and palm oil if possible.

My dog is allergic to grains, what can I use instead of oats?
You can try almond flour or coconut flour, but the texture will be drier. You’ll need to adjust with more moisture.

Can I eat these myself?
Yep. They’re 100% human-safe. Just maybe a little bland unless you like chewy PB oat cookies with no sugar.

Are these soft or crunchy?
They come out chewy in the middle with slightly crisp edges. You can bake a little longer for a crunchier texture.


Wrap Up

Making something by hand, especially for your dog, is one of the best feelings. It’s quick. It’s easy. And it’s honestly kind of fun watching your dog lose their mind over something you made from scratch.

If you give these a try, I’d love to hear how they turned out. Did your dog love them? Did you make any fun swaps or add your own twist?
