These four-ingredient peanut butter banana dog treats are so easy to make. Healthy homemade dog treats are a great way to give your dog a tasty treat that you can feel confident about.

As a dog owner, I know that my dog is spoiled rotten. She will do just about anything for a cookie, including “waiting” with a treat on her head until she is given permission to eat it. These tasty treats are an easy way to spoil her – and it is such an easy recipe with no added sugar.

These limited ingredient dog treats are also a great way to use up some overripe bananas. If you are sick of bananas, you can make some dog cookies for your favorite pup.

If you don’t have bananas, you can also use canned pumpkin or unsweetened applesauce. These easy, homemade peanut butter banana dog treats are great for older dogs as well, as they are on the softer side.

As an added bonus, I’ve even been told that these yummy dog treats are toddler approved as well!

🥘 Ingredients Needed

A picture of the ingredients of peanut butter and banana dog treats: oats, peanut butter, banana, and an egg.
  • Mashed Banana – A really ripe banana works great for this recipe.
  • An Egg
  • Rolled Oats – I like to use Old Fashioned Oats, but you can also use whatever you have on hand – Quick Cooking Oats will work fine as well.
  • Creamy Peanut Butter – Make sure that you find a kind of peanut butter that does not have any artificial sweeteners like xylitol in it as it is toxic to dogs. Natural peanut butter usually works well!

🥣 How to Make Them

These homemade treats are really easy to make. First, preheat your oven to 350°F.

Then, mix all of your ingredients together in a medium size bowl. (Picture 1) Let them sit for a few minutes for the oats to absorb some moisture. (Picture 2)

Line a baking sheet with parchment paper (Picture 3), then drop the treat dough onto the cookie sheet using a tablespoon. (Picture 4) (If you do not have parchment paper, you can use a baking liner or spray your cookie sheet with non-stick cooking spray.)

Press the treats down a little, so they lie a little bit flat, then bake for 12-15 minutes.

The cookies will not look much different after they are cooked – just a little brown on the edges of the oats and they will be slightly firm when you push down on them. (Almost like a perfectly cooked meatball or the top of a cupcake.)

Does anyone else have a dog that stares them down when a peanut butter jar is opened? This is the look that I get whenever there is peanut butter around.

✏️ Helpful Tips

  • I highly recommend storing these dog treats in the fridge. Since they have a lot of moisture in them, they can grow mold really easily.
  • Be sure to use a peanut butter that does NOT contain xylitol. It is harmful to dogs and could result in death if consumed.
  • Introduce new foods to your dog slowly to avoid an upset stomach.
  • Let the cookies cool before feeding them to your dog or before placing them in an airtight container, then store them in the refrigerator or freeze them.

🥫 How to Store Homemade Dog Treats

These treats will last at room temperature for 3-5 days, though I highly recommend keeping them in the refrigerator because they have a lot of moisture in them. They will last for about a week in the refrigerator and they will last for at least six months in the freezer.

I like to freeze them, then in the morning I take a few out and leave them on the counter. Melly gets pieces of treat throughout the day.

🙋‍♀️ Frequently Asked Questions

Yes. Dogs LOVE peanut butter. Just be sure to use a natural peanut butter that does not contain an artificial sugar substitute like xylitol, as they can be toxic to dogs and can cause hypoglycemia, seizures, liver failure, or even death.

Can dogs eat bananas?

Yes. Dogs can eat bananas. They have a lot of sugar in them, so dogs should not eat A LOT of bananas, but they are fine in moderation and in recipes like homemade treats.

    I made this for our 2 boys they’re both 9yrs old (but don’t always act thekr age lol) I kinda followed the recipes ingredients but I played around with it as well. I made a bigger batch for our big boys (our boys are about 75 to 80Lbs each) i used 4 eggs 5 bananas they were organic & around a medium size some a little smaller & i used 3 to 4 cups of oats (not the instant) .i just made sure it came together & had the stickiness that it should. I also added 1Tsp. Of cinnamon to it. I had also pulsed the oats just enough to break em up & have various sizes of oats. I also put it in the fridge for a few mins cause the eggs in it. I also made more than 1 cookie sheet so I put the 2nd one in the fridge til the 1st ones were done baking. I did flatten em out like a cookie but kept em about 1/4 I didn’t measure. I used parchment paper as well. This recipe is 1 that u can swap the bananas for another fruit purée that’s safe for ur babies & just add more or less oats & make em chunky or into smaller bits for smaller dogs. As long as its sticky, holds together & u watch to make sure u don’t add anything that has hidden dangers in the food product ur using. Have fun mixing up what u use. Also please remember to check everything not all fruits, Veggies, nuts etc are safe for dogs & if u use canned or pre packages of items check closely kept sodium low or none same with sugar & if ur pet as any health problems take that in account when u make these treats. Change it to fit ur pets needs,or favorite safe foods.
