A quick but important note before you start: even with dog-friendly ingredients, homemade treats like these should only make up a small part of your dog’s overall diet. Every dog has different nutritional needs and sensitivities, so if your dog has any known allergies, digestive issues, or health conditions, check with your veterinarian before introducing a new treat.

Ingredients for Sweet Potato & Oat Dog Biscuits

• 1 cup cooked and mashed sweet potato, cooled
• 2 cups old-fashioned rolled oats
• 1 large egg
• 1 cup whole-wheat flour
• 1–3 tablespoons water, if needed

Optional Add-Ins

• ¼ teaspoon ground cinnamon
• 1 tablespoon ground flaxseed
• 2 tablespoons unsweetened applesauce
• ¼ cup finely shredded carrots

Ingredient Notes

Sweet potato. Use plain cooked sweet potato with no added salt, butter, or seasoning of any kind. Sweet potato is naturally sweet, easy to digest, and a good source of fiber and vitamins for dogs, which is why it works so well as the base flavor here instead of added sugar. Let it cool before mixing, since hot sweet potato can partially cook the egg too early.

Old-fashioned rolled oats. Oats are a gentle, easily digestible grain for most dogs and give these biscuits their hearty texture and satisfying crunch.

Egg. The egg helps bind the dough together and adds a bit of protein. This recipe is baked long enough to cook the egg thoroughly.

Whole-wheat flour. This adds structure to the dough so the biscuits hold their shape well when cut and baked.

Substitutions and Variations

• Pumpkin instead of sweet potato: You can substitute the mashed sweet potato with an equal amount of 100% pure pumpkin purée (not pumpkin pie filling, which contains added sugar and spices).
• Oat flour instead of whole-wheat flour: For dogs with wheat sensitivities, you can replace the whole-wheat flour with oat flour blended from additional rolled oats, adjusting the liquid slightly as needed.
• Added carrot: Finely shredded carrots add extra texture, color, and a mild natural sweetness.
• A touch of cinnamon: A small amount of cinnamon is generally considered safe for dogs in small quantities and adds a warm flavor note, though it’s entirely optional.
• Applesauce for extra moisture: A couple tablespoons of unsweetened applesauce can help soften the dough slightly if it feels too dry.

Kitchen Equipment

• Baking sheet
• Parchment paper
• Large mixing bowl
• Rolling pin
• Bone-shaped cookie cutter (paw print or circle shapes also work well)
• Wire cooling rack

How to Make Sweet Potato & Oat Dog Biscuits

Step 1: Preheat and Prep

Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.

Step 2: Cook and Cool the Sweet Potato

Cook the sweet potato until completely tender, then mash it until smooth and let it cool. It’s important that the sweet potato has cooled before mixing it into the dough, since adding it while still hot can partially cook the egg prematurely.

Step 3: Mix the Dough

In a large bowl, combine the cooled mashed sweet potato, oats, egg, and whole-wheat flour. Mix until a firm, workable dough forms. If the dough feels too dry or crumbly, add water a tablespoon at a time. If it’s too sticky, work in a little extra flour.

Step 4: Roll and Cut

Roll the dough out on a lightly floured surface to about ¼ inch (6 mm) thick. Cut into bone shapes using a cookie cutter, and arrange the pieces on the prepared baking sheet.

Step 5: Bake

Bake for 22 to 28 minutes, or until the biscuits are firm and lightly golden around the edges. For extra-crunchy biscuits, turn off the oven once baking is done and leave the biscuits inside for another 20 to 30 minutes as the oven cools. This gradual drying-out period gives them a firmer, crunchier bite.

Step 6: Cool Completely

Transfer the biscuits to a wire rack and let them cool completely before serving. Full cooling also helps them firm up to their final crunchy texture.

Expert Tips for the Best Results

• Cool the sweet potato fully before mixing. This prevents the egg from partially cooking too early and helps keep the dough easy to work with.
• Roll the dough to an even thickness. Consistent thickness helps the biscuits bake evenly, so you avoid some pieces being underdone while others turn out overly hard.
• Use the oven-cooling step for extra crunch. This step deepens the crunch without any risk of burning, since the oven is already off.
• Size biscuits appropriately for your dog. Cut larger shapes for bigger dogs and smaller ones for small breeds or puppies.
• Let the biscuits cool fully before storing. Packing away warm biscuits can trap steam and lead to a softer texture or promote spoilage.

Common Mistakes to Avoid

Using seasoned or salted sweet potato. Extra salt, butter, or seasoning isn’t necessary for your dog and can be harder on their digestive system. Stick with plain, unseasoned cooked sweet potato.

Skipping the cooling step for the sweet potato. Mixing in hot sweet potato can partially cook the egg too early and throw off the dough’s texture.

Rolling the dough unevenly. Biscuits of inconsistent thickness will bake unevenly, leading to some pieces that are too soft and others that are overly hard.

Serving biscuits before they’re fully cooled. Warm biscuits are softer than they’ll be once fully cooled, so it can be hard to judge the final texture, and warm treats are more prone to sticking together in storage.

Using pumpkin pie filling if substituting pumpkin. If you swap in pumpkin instead of sweet potato, be sure to use 100% pure pumpkin purée, not pie filling, which contains added sugar and spices.

How to Serve Sweet Potato & Oat Dog Biscuits

These biscuits work well as an everyday treat, a training reward broken into smaller pieces, or a special addition to a treat jar by the door. As with any homemade treat, they should be given in moderation and shouldn’t replace a balanced, complete dog food as your pet’s primary diet.

Make-Ahead Instructions

This recipe is easy to make ahead, since the biscuits store well and hold their crunch for days once fully cooled. You can bake a full batch at the start of the week and simply pull biscuits from the pantry, refrigerator, or freezer as needed.

Storage Instructions

Room Temperature or Refrigerating

Because these biscuits are fully baked and low in moisture, they can be stored in an airtight container at room temperature for up to 1 week, or in the refrigerator for slightly longer freshness.

Freezing

For longer storage, freeze the biscuits in a freezer-safe container or bag for up to 3 months. Thaw at room temperature before serving.

Reheating

Reheating isn’t necessary for these biscuits, since they’re meant to be served at room temperature. If a batch has softened slightly in storage, you can warm them in a 300°F (150°C) oven for a few minutes to re-crisp them before letting them cool again.

Frequently Asked Questions

Can I make this recipe ahead of time? Yes. These biscuits store well, so you can bake a batch in advance and keep it at room temperature, refrigerated, or frozen until you’re ready to use it.

How long do these dog biscuits last? Stored in an airtight container at room temperature, they’ll keep for about 1 week, or up to 3 months in the freezer.

Can I freeze homemade dog biscuits? Yes. Freeze them in a freezer-safe container or bag and thaw at room temperature before serving.

Can I use pumpkin instead of sweet potato? Yes. An equal amount of 100% pure pumpkin purée works well in place of the mashed sweet potato.

Why is my dough too crumbly or too sticky? If the dough is dry and crumbly, add water a tablespoon at a time until it holds together. If it’s too sticky to roll, work in a bit more flour.

Why aren’t my biscuits crunchy enough? This usually means they need more time in the oven, or could benefit from the optional oven-cooling step, which lets residual heat continue drying them out for extra crunch.

How many of these treats can I give my dog? Treats like these should only make up a small portion of your dog’s daily diet. The right portion size depends on your dog’s size, weight, and regular food intake, so when in doubt, check with your veterinarian, especially for very small dogs or dogs with health conditions.
