🧰 Equipment Needed

Oven
Mixing bowl

Baking sheet
Parchment paper
Rolling pin (or a bottle)
Cookie cutter or knife
Cooling rack
Potato masher (if cooking sweet potato at home)

🛒 Ingredients

Main ingredients

1 cup Cooked, mashed sweet potato (no added salt or sugar)
1/2 cup Rolled oats, lightly processed to coarse flour
2 tablespoons Fresh flat-leaf parsley, finely chopped

Binders & structure

1 1/2 cups Oat flour (or whole wheat flour if not gluten-sensitive)
1 large Large egg
1 tablespoon Coconut oil, melted

Finishing & optional

2-3 tablespoons Warm water (to adjust dough consistency)
1 tablespoon Extra rolled oats for topping (optional)

👩‍🍳 Directions

Prepare

Preheat the oven to 325°F (160°C). Line a baking sheet with parchment paper.
If you haven’t already, cook and mash sweet potato until smooth and allow to cool slightly. Finely chop the parsley.

Mix & shape

In a large bowl combine mashed sweet potato, melted coconut oil and the egg; mix until smooth.
Add oat flour and processed rolled oats to the wet mixture, then stir in the chopped parsley. The dough should come together but remain slightly tacky; add 1 tablespoon of warm water at a time if needed to achieve a firm, rollable dough.
Turn the dough onto a lightly floured surface (use oat flour). Roll to about 1/4-inch (6 mm) thickness. Cut into small biscuit shapes with a cookie cutter or small knife — aim for bite-size portions appropriate for your dog.
If desired, press a few extra rolled oats on top for texture.

Bake & finish

Arrange biscuits on the prepared baking sheet about 1/2 inch apart. Bake at 325°F (160°C) for 25–30 minutes, flipping once at the halfway point, until golden and crisp.
Remove from oven and transfer to a cooling rack. Let biscuits cool completely — they will crisp further as they cool.
Store cooled biscuits in an airtight container in the refrigerator for up to 10 days or freeze for longer storage (see Storage & Reheating).

Notes

Storage & Reheating

Store completely cooled biscuits in an airtight container in the refrigerator for up to 10 days. For longer storage, freeze in a sealed freezer-safe bag for up to 3 months; thaw in the refrigerator or at room temperature before serving. Do not microwave treats with metal containers; if you prefer a slightly softer texture, warm a frozen biscuit for 10–15 seconds in the microwave, then cool before giving to your dog.

Variations

Swap oat flour for a certified gluten-free oat flour to keep the recipe gluten-free. For a slightly different flavor, replace 1 tablespoon coconut oil with olive oil. Omit coconut oil entirely for a lower-fat version and increase egg to 1 large plus 1 tablespoon warm water if needed for dough binding.

FAQs

Are these biscuits suitable for small and large dogs?

Yes. Cut biscuits to an appropriate bite-size: small shapes for small breeds and larger shapes for medium to large dogs. Always supervise treat feeding and adjust portion size for your dog’s size and caloric needs.

Can puppies eat these treats?

Puppies over 8 weeks old that are already on solids can have small amounts as an occasional treat. Check with your veterinarian for age-appropriate portioning and to ensure ingredients fit your puppy’s dietary needs.

What if my dog has grain sensitivities or allergies?

Use certified gluten-free oat flour or substitute with brown rice flour if advised by your veterinarian. Introduce any new ingredient slowly and monitor for signs of intolerance.

How often can I give these biscuits?

These are occasional treats. Offer them sparingly — for most dogs, a few small biscuits per week is appropriate depending on overall calorie intake. Factor treats into your dog’s daily calorie allowance.

Can I substitute ingredients if I don’t have them?

Yes. Oat flour can be swapped with whole wheat flour unless gluten is a concern. Coconut oil may be replaced with olive oil, but avoid sweeteners, salt, or any disallowed ingredients (see recipe safety).

How should I store leftovers safely?

Refrigerate in an airtight container up to 10 days or freeze up to 3 months. Thaw in the refrigerator or at room temperature; discard if you notice mold, odd smell, or slimy texture.

How many biscuits is a proper portion?

Portion depends on biscuit size and your dog’s weight. For a small dog, 1 small biscuit; for medium dogs 1–2; for large dogs 2–3. Reduce portions for dogs on calorie-restricted diets and consult your veterinarian for exact guidance.

Any tips to make biscuits crisper?

Roll the dough thinner (about 1/4 inch) and bake until fully dry and golden. Allow biscuits to cool completely on a rack — they crisp as they cool. Flip once during baking for even crisping.

When should I NOT feed these biscuits?

Do not feed if your dog has an ingredient-specific allergy (e.g., oat or egg allergy) or if your veterinarian has restricted certain foods. Avoid giving to dogs with pancreatitis or fat-restricted diets without vet approval due to the oil and egg content.

Should I check with my veterinarian first?

Yes. Consult your veterinarian before introducing new treats if your dog has health conditions, is on medication, or has strict dietary restrictions.

Conclusion

Sweet Potato & Parsley Breath Biscuit Treats are a simple, crunchy occasional treat made with dog-safe ingredients. They are not a complete diet and should be offered sparingly as part of a balanced feeding plan. Introduce new foods gradually, watching for any signs of intolerance. If your dog has health conditions or special dietary needs, consult a veterinarian before offering these treats. Enjoy making a small batch for training rewards or special moments with your dog.
