Who doesn’t love to spoil their dog? These Crunchy Homemade Dog Treats are made with blueberries, peanut butter, and oats and will become your dog’s new favorite cookie!

I made these homemade 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. They seemed a touch freezer burnt, so we didn’t really want to eat them.

Our dog, Melly, loves this one kind of crunchy blueberry dog 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 okay to me but are kind of bland – they are also dry and crumbly, like a Milk Bone treat. Some people who have made these told me that their toddlers really like them.)

I love being able to give my dog homemade 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!

🥘 Ingredients Needed

FULL INGREDIENT MEASUREMENTS ARE IN THE RECIPE CARD AT THE BOTTOM OF THE POST ABOVE THE COMMENT FORM

  • 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 – Optional, but not necessary. It is also fine to give dogs a quarter of a teaspoon of salt divided among 35 large dog biscuits that they are not going to be eating all in one day. Dogs need electrolytes too! Commercial dog food has salt in it, as does the pretzel or potato chip they might snatch up off the floor that you drop, just keep them away from a salt lick.
  • Warm Water or Bone Broth (without Onion) – I like to make my own, but you can buy it as well.
  • Optional Additions – Bone Meal, Kelp Flakes, Turmeric, and Chia Seeds

🥣 How to Make Homemade Dog Treats

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) (add bone meal, kelp, and turmeric now if you are using it.)

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 (or broth) 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 coated with artificial sweeteners.

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 Size Suggestions

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 😉

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!)

🫙 How to Store Homemade Dog Treats

Store these treats in an airtight 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. Hi! If I’m using frozen blueberries should I allow them to thaw and drain before using in this recipe? Thank you!

    1. They are completely optional – none of them will alter the final product, so you can add them if you want to add the extra nutrition for your dog, but if you don’t have them on hand, you don’t have to add them this time! You can add one at a time or all of them.

  2. Would be nice if you actually put quantities in a list like one would do for a regular recipe.

    Very disappointed as I really wanted to make this for my dog.

    You seemed to be more focussed on your experience of making these and your dog liking them.

    1. There is a printable recipe card with full measurements right above where you left this comment. Hope your dog enjoys them!
