Who doesn’t love to spoil their dog? These crunchy, blueberry dog treats made with peanut butter and oats will become your dog’s new favorite cookie!

I made these dog biscuits on a whim. I was cleaning out the freezer to load up on fresh berries and found a bag of blueberries from last year.

Our dog, Melly, loves this one kind of crunchy blueberry treat that is hard to find, so I thought it might be fun to make her some. She LOVES them. (They smell so good that we actually tasted them. They taste pretty good but are kind of dry and crumbly, like a Milk Bone treat.)

I love being able to give my dog treats with recognizable ingredients. I know what is in them, so I know she isn’t being fed garbage. I also love how much she LOVES them. Melly will sing for her treats!

🥘 Ingredient Notes

A picture of the ingredients in blueberry dog treats on a white tile background, labeled.
  • Blueberries (if they are frozen, you can also add the juice from the bag) – optionally, you can use dried blueberries but you will need to add more liquid
  • Oats – (I like to use Old Fashioned Oats)
  • Whole Wheat Flour – I usually purchase King Arthur Flour – Regular Whole Wheat and White Whole Wheat both work.
  • Eggs
  • Peanut Butter – Make sure that you find a kind of peanut butter that does not have any artificial sweeteners like xylitol in it – that is toxic to dogs.
  • Ground Cinnamon
  • Optional: Kosher Salt – we use salt because we sometimes taste them. (These treats are apparently very popular with toddlers!)
  • Warm Water

🍽 Equipment Needed

🥣 How to Make Them

These dog treats are really easy to make, and your dog will love them!

First, preheat your oven to 350°F.

Then, add your blueberries to your mixing bowl. If you are using frozen blueberries, smash them around a little with the mixer. (Picture 1) This will help break the big blueberries up into smaller pieces and mash some of the juices out. If you are using fresh or dried blueberries, give them a rough chop so that they are easier to incorporate in the dough.

Next, add your oats and mix them up with the blueberries. (Picture 2 – 3)

Finally, add the rest of your ingredients – flour, eggs, kosher salt, peanut butter, and cinnamon. (Picture 4)

Mix together until everything is mostly combined – it will be a bit dry and crumbly. (Picture 5)

Now, add about 1/8 cup of warm water to the dough and mix until it sticks together in a ball. If the dough still seems dry, continue adding warm water in 1/8 – 1/4 cup increments. (Picture 6) (My blueberries were frozen and released a bunch of liquid when they defrosted, so I only added 1/8 cup of water. If your blueberries are fresh, you may need up to 1/2 a cup of water. If you are using dried blueberries, you will definitely need to add at least 1/2 a cup of water. Ideally, you want the dough to be like a pasta dough or sugar cookie dough – stiff but moldable and not runny and sticky.)

Next, flour a clean surface to roll out your dough with a rolling pin (or a bottle of wine – no one here is judging.) (Picture 7) Roll it out to about 1/2 an inch thick. It doesn’t have to be perfect, but you don’t want to make these really thin or they will burn. If you make them a little too thick, you can get away with just cooking them for a little longer.

Then, cut out your treats using your favorite cookie-cutters. (Picture 8 – 9) If you don’t want to use a cookie-cutter, you can also use a pizza cutter or sharp knife and just cut 1 x 1-inch squares or 1 x 2-inch rectangles.

Place your cookies on a cookie sheet lined with parchment paper or a non-stick baking mat. They don’t have to be spaced too far apart because they won’t really expand, but they will stick together if they are touching. (Picture 9)

🙋‍♀️ Frequently Asked Questions

What kind of blueberries can you use?

You can use fresh, frozen, or even dried blueberries. If you use dried blueberries, try to avoid sweetened blueberries and definitely avoid blueberries made with artificial sweetener.

Can you make these treats with any other fruit?

Absolutely! You can replace the blueberries with one cup of canned pumpkin or one cup of unsweetened applesauce. If you are using applesauce or pumpkin, you will most likely not need to add much water so keep an eye on that! (You can also use mashed, cooked sweet potato!)

Can you bake these treats in other shapes?

Absolutely. I love using bone-shaped cookie-cutters, but you can just cut the dough into squares, rectangles, circles, hearts – even Santa Claus or Christmas trees – whatever your heart desires.

What can you use in place of a rolling pin?

If you do not have a rolling pin, you can use a bottle of wine or any large and round glass bottle. Just make sure that you clean the outside of the bottle and don’t be too rough with it.

🍳 Serving Suggestions & Uses

Serve these treats as often as you would give your dog a regular hard biscuit – not too many, but make sure they are happily spoiled πŸ˜‰

Melly weighs somewhere around 45 pounds, and she usually gets 2 or 3 of these a day. (I’m sure she would happily accept more if we offered!)

🥫 Storage/Shelf Life/Reheating

Store these treats in an air-tight container. They are really crunchy, so as long as they are not exposed to moisture, they should last a good while. (I like to freeze half of the batch since I only have one dog and she won’t go through them that quickly.)

  1. These sound great. Can you use regular flour? I want to add shredded carrots and shredded apples to your recipe. Would I have to adjust any part of the recipe?
    Thanks for your help I look forward to hearing back from you.

    1. Yes! You can use regular flour – you just might need to add less liquid. The apples and carrots should be fine to add – I would just use fewer blueberries so the dough doesn’t fall apart!

  2. 5 stars
    I originally got treats like these awhile back and decided to search up a recipe to bake. Oh my goodness I am so happy that she LOVES them!!!! I always have a tough time getting her to eat real fruits and veggies so this is a great alternative than just her kibble.

  3. Hey Chris. Not sure if you were trying to stir up trouble. But read up on it before posting things you really are not sure of or think you know. DOGS CAN HAVE BLUEBERRIES. THEY ARE GOOD FOR THEM.
    I do know this is 2 years later. But thought I’d share since I just started baking these kind.

    1. Thanks for helping Nancy! Yes, I’m not sure why so many people think dogs can’t have blueberries, but they can. So many great vitamins in blueberries for them and for us. Now, if they ate a whole pint of them, they might not feel awesome, but we wouldn’t either πŸ™‚

  4. Hi Kari, Thank you for the recipe. Pretty easy to make, and my dog loves them. How long do you think these keep in an airtight container? I pulled a baggie from the freezer, have a small dog, and have not gotten through them yet. They are probably going on a month now. Wondering if they will go ‘bad’.

    1. I think it depends on the humidity in your house and how “airtight” the container is. I have kept some in a mason jar on my counter for more than two months and they are as crunchy as the day I baked them and I currently have a bag sitting out that has been going for at least a month and a half. As the weather gets warmer, if you live somewhere humid – I would consider keeping them in the fridge or freezer!

  5. Thanks! I ended up buying old-fashioned oats and made them today with pumpkin. The pups seem to enjoy them and I have them in an air-tight container (not sure I’ll need that as I have three dogs). I’m sure they’ll go quickly!

    1. They do go quickly, but it is good to keep them sealed so they don’t absorb any moisture from the air! I’m glad the pups love them πŸ™‚

    2. 5 stars
      Made these today for my Scout. She loved them! Accidentally bought steel cut oats and still turned out great! Thanks for the new recipe in our rotation!

  6. Hi, I saved this recipe for ages, intending to make these one day. That day is now! However, after buying the flour, etc. I realized that the oatmeal I have in the cabinet is 1-minute oatmeal. Can I use this or do I need to buy regular oatmeal for these biscuits?

    1. Hey Sue! It should be fine, as long as the oatmeal doesn’t have any added sugar or anything. You might not need to add as much water when mixing the dough, but I think it would work!

      1. Absolutely! I’ve made this recipe with cranberries & strawberries and both came out great! Just make sure that you add enough extra liquid to the dough if needed πŸ™‚

    Love these!
    Thank you for sharing your recipe. I make these treats weekly for my dog, Jett. He LOVES them and they are pretty healthy. I have tweaked the recipe a little with more oats, blueberries, and peanut butter.

  8. So I am a kid well teen and I made your dog treats for the maine sampler my dog really loves them and I can not wait to hear about every one els’s dogs. I did have to make the circles with my hands cause I have no cutter’s but its ok. I made 3 batches with the doe. It was fun thank you for sharing this. I surely recommend this to other people.

  9. 5 stars
    Add a secret ingredient of some grated up all natural beef jerky I made. I had intended to make two separate batches one if blueberry and the other of pumpkin since my grandpuppies like pumpkin, but discovered that I only had enough ingredients for one batch so the original fourth cup turned into half cupm my dogs didn’t mind so I’m hoping my grandpuppies will like it too! They really smelt like bacon biscuits cooking. My grandkids wanted to eat them too…..lol…

  10. 5 stars
    This is my go to biscuit recipe. My dogs and those I give them to cannot get enough. I do not add salt, there is zero benefit to the recipe and it is not good for the dogs. I use either cinnamon or turmeric with a dash of pepper as I have an older dog with joint pain which the turmeric helps. I also use a sodium free bone broth instead of the water. I also found a slightly moister dough results in a crisper biscuit. Over all a fantastic recipe.

      1. Hello, my son is making dog treat to sell for a little business. He is allergic to peanut. Do you think sunbutter will work? There are 3 grams of sugar per serving, salt and sunflower seeds. Thank you!
        Blythe

        1. How cute! Yes – that should work – my dog loves to lick the spoon after I eat sunbutter so they should be a big hit!

  11. 5 stars
    My dog loves these treats! I just put my second batch in the oven–the first only lasted a week. I really like that they are quick and easy to make, and since they’re relatively thick, I can fit the whole batch on a large cookie sheet at one time. Thank you for sharing!

  12. DOGS SHOULD NEVER have blueberries!!!! They’re toxic to their system! Please add a CLEAR warning to your post or else you risk killing someone’s dog. I can’t believe your dog hasn’t gotten sick!

    1. Hey Chris, I actually checked with my vet before making this recipe because a berry treat that my dog loved from Nutro was getting too expensive. He recommended berries in her diet to help incorporate different vitamins and minerals. If you search on Google “Can dogs eat blueberries?” there are hundreds of sources promoting berries for canine health, including the American Kennel Club, who says, “Yes, dogs can eat blueberries. Blueberries are a great source of vitamins, minerals, antioxidants, and more. This fruit is a healthy snack for both large and small dogs, and most pups love them.” Being such a public source of dog information, I would imagine they would get in a lot of trouble giving out bad advice. Grapes (and dried as raisins) are a commonly known fruit that is toxic for dogs – maybe that’s what you are thinking of?

  13. Would love to make these! is it possible to switch the flour out to another type? I have oat flour, garbanzo bean flour and coconut flour ?

    1. I have not made these with another flour, but since the dough doesn’t really rise or require much gluten for elasticity like bread does, you would probably be okay using the oat flour! They just might be a little more dry and crumbly!

  14. 5 stars
    These look great, kari! I’m going to make them for our pup, harry. πŸ™‚
    You might want to add a warning about xylitol in peanut butter… more brands have been “sneaking” that in as a sweetener, and it’s extremely toxic to dogs. So it’s something people definitely need to watch out for.
