3 Ingredient Sweet Potato Dog Cookies (Easy Homemade Treats Your Pup Will Love)

Sometimes the best dog treat recipes are the ones with almost nothing in them. These sweet potato dog cookies use just three ingredients: sweet potato, oat flour, and an egg.

There’s no sugar, no oil, and no long shopping list, just a soft, lightly sweet cookie that dogs go crazy for.

If your dog loves the flavor of sweet potato, you’ll also want to try my Easy Homemade Sweet Potato Dog Chews, which are chewy and dried, and my Sweet Potato Dog Ice Cream for a frozen option.

These cookies sit in the middle: soft, easy to bake, and perfect for training or a daily reward.

Why You’ll Love These Sweet Potato Dog Cookies

A few reasons this recipe is a keeper.

Only three ingredients. Sweet potato, oat flour, and egg.

No added sugar. Sweet potato provides all the natural sweetness.

Soft and gentle. Easy for puppies, seniors, and dogs with sensitive teeth.

Quick to make. About 10 minutes of prep and 20 minutes in the oven.

Great for sensitive dogs. Simple, familiar ingredients.

Freezer friendly. Bake a big batch and keep extras for later.

Is Sweet Potato Safe for Dogs?

Plain, cooked sweet potato is a popular, dog friendly ingredient, as long as you prepare it the right way.

Cook it fully. Raw sweet potato is hard to chew and digest.

Remove the skin if your dog has a sensitive stomach. The skin is safe in small amounts, but it’s tougher to digest.

Keep it plain. No butter, salt, brown sugar, marshmallows, or spices. Nutmeg is toxic to dogs.

Serve in moderation. Sweet potato is high in fiber and natural sugar, so too much can cause loose stools or weight gain.

Check with your vet if needed. Dogs with diabetes or weight concerns should have sweet potato treats only with veterinary approval.

Ingredients You’ll Need

Here’s what goes into the dough and what each ingredient contributes.

Mashed cooked sweet potato is the star. It adds natural sweetness, moisture, fiber, and beta carotene.

Oat flour gives the cookies structure. You can make it by blending rolled oats until fine. Whole wheat flour also works.

One egg binds everything together and adds a little protein.

Ingredient List

• 1 cup mashed cooked sweet potato, cooled
• 1 1/2 cups oat flour, plus more for rolling
• 1 large egg

How to Make 3 Ingredient Sweet Potato Dog Cookies

1. Bake, steam, or boil a sweet potato until very soft. Peel it, if you like, and mash it until smooth. Let it cool.
2. Preheat your oven to 350°F and line a baking sheet with parchment paper.
3. In a large bowl, mix the mashed sweet potato and egg until combined.
4. Stir in the oat flour until a soft dough forms. If it’s sticky, add a spoonful more oat flour.
5. Turn the dough onto a floured surface and roll to about 1/4 inch thick.
6. Cut into shapes with a cookie cutter and place on the baking sheet.
7. Bake for 18 to 22 minutes, until the edges are lightly golden and the cookies are firm.
8. Cool completely on a wire rack before serving.

Getting the Right Texture

For soft, chewy cookies, roll the dough a little thicker and bake closer to 18 minutes.

For crunchy cookies, roll thinner, bake a few minutes longer, and leave them in the turned off oven for an hour.

Sweet potato dough can be sticky, so flour your hands and the surface well. Chilling the dough for 15 minutes also makes it easier to handle.

If the dough is too dry, add a teaspoon of water. If it’s too wet, add a little more oat flour.

Mash the sweet potato well. Lumps make the dough uneven.

Recipe Variations

Once you’ve made the base recipe, these are easy to try.

Sweet potato and peanut butter. Add 2 tablespoons of xylitol free peanut butter.

Sweet potato and cinnamon. Add a light pinch of Ceylon cinnamon.

Sweet potato and pumpkin. Replace half the sweet potato with plain pumpkin puree, like in my Homemade Pumpkin Applesauce Dog Treats.

Sweet potato and bacon. Add a small amount of finely crumbled bacon, similar to my Dog Treats with Sweet Potato and Bacon.

Mini training cookies. Cut into tiny squares for pea sized rewards.

Common Mistakes to Avoid

Adding butter, sugar, salt, or spices. Keep it plain.

Using sweet potato pie filling. It contains sugar and spices.

Using a lumpy mash. Smooth it out for even dough.

Rolling it too thin without chilling. The dough will tear.

Storing them while warm. Cool completely first.

Giving too many. Sweet potato is high in fiber and sugar.

How Many Cookies Can a Dog Have?

One or two cookies is plenty for a small dog, and two to three for a larger dog.

Treats should make up only a small part of your dog’s daily calories, with the rest coming from a complete and balanced diet. If you’re unsure how it fits into your dog’s day, ask your veterinarian.

How to Store Sweet Potato Dog Cookies

These cookies contain fresh sweet potato and egg, so they need cool storage.

Refrigerator. Store in an airtight container for up to 5 days.

Freezer. Freeze in a sealed bag or container for up to 3 months.

Check before serving, and discard anything that smells off or shows signs of mold. For treats that last longer, see my DIY Dog Biscuits That Last for Weeks.

Can You Freeze Sweet Potato Dog Cookies?

Yes, and freezing is the easiest way to keep a big batch fresh.

1. Cool the cookies completely.
2. Arrange them in a single layer on a tray and freeze for about an hour.
3. Transfer to a labeled freezer bag or container.
4. Thaw a few at room temperature for 10 minutes before serving.
