Ingredients
  

Dry Ingredients
  • 1 cup Oat flour
  • 1/2 cup Whole wheat flour
  • 1 tbsp Ground flaxseed
  • 1/8 tsp Baking soda (optional for slight lift)
Wet Ingredients
  • 1/2 cup Natural unsalted peanut butter
  • 1 each Large egg
  • 1 tbsp Coconut oil, melted
  • 2-4 tbsp Water
Mix-ins & Toppings
  • 1/2 cup Fresh or thawed blueberries
  • 2 tbsp Unsweetened plain yogurt (optional glaze)

Equipment

  • Mixing bowl
  • Whisk
  • Rubber spatula
  • Measuring cups and spoons
  • Baking sheet
  • Parchment paper
  • Rolling pin (or jar)
  • Cookie cutter or knife
  • Oven
  • Cooling rack

Method
 

Preparation
  1. Preheat the oven to 325°F (160°C). Line a baking sheet with parchment paper and set a cooling rack nearby.
  2. If using frozen blueberries, thaw and drain any excess liquid. Lightly mash half of the blueberries with a fork to release some juice; keep the rest whole.
Make the dough
  1. In a large bowl, whisk together oat flour, whole wheat flour, ground flaxseed, and baking soda (if using).
  2. In a separate bowl, mix the peanut butter, egg, and melted coconut oil until smooth. Add 2 tablespoons of water to start, then combine with the dry ingredients.
  3. Stir until a stiff dough forms; add up to 2 more tablespoons of water a little at a time only if the dough is too dry. Fold in the mashed and whole blueberries gently so they distribute without turning the dough soggy.
Shape and bake
  1. Turn the dough onto a lightly floured surface and roll to about 1/4 inch (6 mm) thickness between two sheets of parchment to prevent sticking.
  2. Cut into small shapes (about 1.25–1.5 inches) with a cookie cutter or knife and transfer to the prepared baking sheet, spacing 1/2 inch apart.
  3. Bake for 18–22 minutes, rotating the pan halfway, until the edges are firm and the centers feel set. For extra crunch, leave them in the warm, turned-off oven for 5–10 minutes with the door slightly ajar.
  4. Cool completely on a wire rack. If using the yogurt glaze, wait until completely cooled, brush a thin layer of unsweetened plain yogurt on top of each biscuit and place in the fridge for 10–15 minutes to set. For a frozen treat option, place glazed biscuits in a single layer on a tray in the freezer until firm, then store frozen.
Serving
  1. Serve small treats according to your dog’s size (see FAQs for portion guidance). Refrigerate or freeze extras and thaw or bring to serving temperature as needed.

Storage & Reheating

Store completely cooled treats in an airtight container in the refrigerator for up to 7 days. For longer storage, freeze in a single layer on a tray until firm, then transfer to a freezer-safe bag for up to 3 months. Thaw in the fridge or at room temperature before serving. Do not microwave with yogurt glaze; instead let come to room temperature or warm slightly in your hands.

Variations

Omit whole wheat flour and use 1 1/2 cups oat flour for a wheat-free version. Replace coconut oil with a small amount of plain canned pumpkin (not pie filling) for a pumpkin-peanut butter twist. For a softer, training-size bite, roll the dough thinner and bake a shorter time for a softer texture.

FAQs

Are these treats suitable for puppies?
Puppies under 6 months have different nutritional needs; offer very small pieces only and check with your veterinarian before introducing new treats to a young puppy.
Are these safe for small or large dogs?
Yes—size the portion to your dog. Small dogs should receive one small bite; medium to large dogs can have one to two, depending on overall calorie intake. See the Portion Control FAQ below.
What if my dog has a peanut allergy?
Substitute the peanut butter with canned plain pumpkin or smooth mashed sweet potato at the same volume. Ensure any swap is free of added sugars or salts.
How often can I feed these?
These are an occasional treat. Offer them sparingly—no more than a few times per week—within your dog’s daily calorie allowance.
Can I substitute flours?
Yes. Use all oat flour for a wheat-free option or a light rice flour blend. Adjust liquid slightly if the dough feels too dry or too wet.
How should I store leftovers to keep them safe?
Refrigerate for up to 7 days in an airtight container or freeze up to 3 months. Always discard if you see mold or an off smell.
How many treats should I give for training or portion control?
For small dogs, break a biscuit into 4–6 small pieces for training. For medium dogs, one small biscuit per reward is typical. Adjust based on your dog’s size and daily calorie needs.
Any preparation tips to prevent soggy treats from blueberries?
Use half mashed and half whole blueberries and avoid overloading the dough. If the dough becomes too wet, add a tablespoon of oat flour at a time until it reaches a workable consistency.
When should I NOT feed these treats?
Avoid if your dog has a known allergy to peanuts, oats, wheat, or coconut. Also skip these treats for dogs on restricted diets without veterinary approval.
Should I consult my veterinarian before feeding these to a dog with health issues?
Yes. Consult your veterinarian before offering these treats to dogs with diabetes, pancreatitis, food allergies, or other medical conditions.

Conclusion

Peanut Butter & Blueberry Bite Dog Treats are intended as an occasional treat or snack—not a complete diet. Introduce new foods gradually and monitor for any signs of intolerance. If your dog has health conditions or special dietary needs, consult a veterinarian before adding homemade treats to their routine. Store and serve responsibly to keep portion sizes appropriate.
