These biscuits combine the natural sweetness of mashed sweet potato with the protein-rich goodness of peanut butter, creating a flavor your dog will love—and one that’s safe, vet-approved, and packed with nutrients. I developed this recipe after my own dog refused store-bought treats, so I knew it had to be something special.
The beauty of these biscuits lies in their simplicity: no complicated techniques, no fancy ingredients, just wholesome staples that come together in a single bowl. Sweet potatoes provide fiber and vitamins, while peanut butter adds protein and a taste dogs can’t resist.

Store them in an airtight container for up to two weeks, or freeze for longer storage. These biscuits are so delicious, even humans might sneak a bite—but don’t tell your dog. Let’s get baking for your furry friend!
Ingredients for sweet potato peanut butter dog biscuit
Five wholesome ingredients your pup will adore—crunchy, healthy, and ready in 10 minutes!
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potato, Mashed 🍠 | 1 cup | Cooked, cooled, no skin |
| Natural Peanut Butter 🥜 | ½ cup | Xylitol-free, unsweetened |
| All-Purpose Flour 🌾 | 2 cups | Unbleached preferred |
| Oat Flour 🥣 | ½ cup | Blended from rolled oats |
| Baking Powder 🧂 | 1 tsp | Aluminum-free |
| Ground Cinnamon 🌿 | ½ tsp | Dog-safe amount |
| Vanilla Extract 🍯 | ½ tsp | Pure, alcohol-free preferred |
| Water 💧 | ¼ cup | Room temperature |
| Egg 🥚 | 1 whole | Room temperature |
| Olive Oil 🫒 | 1 tbsp | For brushing |
| Sea Salt 🧂 | ¼ tsp | Fine grain |
Sweet potatoes are the star here—canned or fresh works, but fresh is more nutrient-packed. Grab the organic kind at Whole Foods or your local farmers market for the best flavor. The peanut butter? Creamy, xylitol-free is a must—check the label, some brands sneak in this toxic sweetener. I always buy the natural kind from Trader Joe's or Costco for bulk savings. For the flour, King Arthur Unbleached is my go-to—it's reliable and easy to find. Pro tip: if you don't have oat flour, just blend rolled oats in a food processor until it's fine.
No peanut butter? Almond butter or sunflower seed butter work in a pinch—just make sure they're also xylitol-free. Short on sweet potato? Pumpkin puree (unsweetened) at the same amount gives similar texture. The cinnamon is optional but adds a nice touch—just 1/4 tsp is plenty for dogs. For vanilla, alcohol-free extracts are best since dogs are sensitive to alcohol. And if you're worried about the egg, flax egg (1 tbsp ground flax + 3 tbsp water) works perfectly for a vegan version—just let it sit for 5 minutes to thicken.
These biscuits stay fresh for 2 weeks in an airtight container at room temperature. For longer storage, freeze them for up to 3 months—just lay them flat on a baking sheet first, freeze solid, then transfer to a bag. I like to portion them into small bags for easy grab-and-go treats. The crispy edges soften within minutes of baking, so let them cool completely before storing. And trust me, your dog will love them more than you'll love sneaking a bite!
Why You'll Love This Recipe
- No-Mess Mixing: I swear by the five-ingredient blend—just mash the sweet potato, stir in peanut butter, and fold the flours. No food processor, no sticky hands, just a big spoon and a bowl. Honestly, my dog doesn’t even notice when I skip the fancy tools.
- Peanut Butter Magic: That creamy peanut butter isn’t just for humans—it turns these biscuits into little flavor bombs. The sweet potato adds natural sweetness, while the oat flour gives them a satisfying chew. My pup goes nuts for them (literally—she barks until I drop one).
- Batch-and-Freeze Ready: Make a double batch on Sunday, bake them, then freeze half. When your dog’s treat jar is empty, just pull out a few and toss them in the oven. No last-minute scrambling, no sad puppy eyes at the store. It’s my secret to guilt-free prep.
- Pocketbook Perk: Sweet potatoes and peanut butter are cheap staples, and oat flour stretches the dough further than all-purpose alone. I’ve fed my dog for weeks with what costs less than a fancy treat bag. Plus, the leftovers? My toddler “accidentally” eats them. (Don’t tell.)
Step-by-step instructions for sweet potato peanut butter dog biscuits
Here's how to make these irresistible treats your pup will beg for in minutes.
Mix Wet Ingredients Until Smooth
In a large mixing bowl, combine the 1 cup sweet potato, mashed with the 0.5 cup natural peanut butter until fully blended. The mixture should be creamy and uniform—no lumps allowed. This is the flavor foundation, so take your time to ensure everything's well incorporated.
Next, add the 1 whole egg and 0.25 cup water to the bowl. Stir gently until everything comes together into a smooth batter. The egg adds binding power while the water helps create the perfect dough consistency. If the mixture feels too thick, add an extra tablespoon of water—just enough to make it workable without being soupy.
Combine Dry Ingredients Separately
In a separate medium bowl, whisk together the 2 cups all-purpose flour, 0.5 cup oat flour, 1 tsp baking powder, 0.5 tsp ground cinnamon, 0.5 tsp vanilla extract, and 0.25 tsp sea salt. The cinnamon adds a warm, dog-friendly flavor that most pups love, while the baking powder ensures a light, crisp texture.
Use a whisk to break up any flour clumps completely—this prevents dense biscuits later. The oat flour adds a nice chewy texture that contrasts beautifully with the crisp edges. Once everything is evenly distributed, create a well in the center of the dry ingredients for the wet mixture.
Form the Dough and Chill
Gradually pour the wet ingredients into the dry ingredients while stirring with a wooden spoon. Mix just until combined—you want to avoid overworking the dough, which can make the biscuits tough. The dough should be soft and slightly sticky but manageable.
Turn the dough out onto a lightly floured surface and knead gently for about 30 seconds until it comes together. If it feels too sticky, add a little more flour, 1 tablespoon at a time, until it holds its shape. Wrap the dough in plastic wrap and refrigerate for 30 minutes—this resting period makes rolling and cutting much easier.
Roll and Cut the Biscuits
After chilling, preheat your oven to 350°F and line two baking sheets with parchment paper. On a lightly floured surface, roll the dough to about 1/8-inch thickness. I like to use a rolling pin, but you can also press it down gently with your hands if you prefer.
Use a 2-inch round cookie cutter or a glass to cut out biscits. Place them about 1 inch apart on the prepared baking sheets—they'll spread slightly during baking. Brush the tops lightly with 1 tbsp olive oil for extra crispiness. This step is where the magic happens—proper spacing ensures even baking and crisp edges.
Bake to Golden Perfection
Bake the biscuits for 12-15 minutes until the edges are golden brown and the centers look slightly underdone. The biscuits should be firm to the touch but still soft in the middle. Rotate the pans halfway through for even baking—this prevents any one side from getting too dark.
Remove from the oven and let them cool on the baking sheets for 5 minutes before transferring to a wire rack. The first few minutes after baking are when they're most fragile, so handle them gently. Once completely cooled, store in an airtight container for up to 5 days or freeze for longer storage. Your pup will thank you!
Pro Tips For Making Sweet Potato Peanut Butter Dog Biscuit
- STEAM THE SWEET POTATO: I learned this the hard way—microwaving sweet potatoes for these biscuits leaves them waterlogged and gummy. Instead, steam them whole with the skin on for 45-60 minutes until fork-tender. The texture stays dry, and the flavor concentrates perfectly for mashing.
- USE ROOM-TEMP PEANUT BUTTER: Cold peanut butter makes the dough stiff and uneven. Scoop it straight from the jar and let it sit for 10 minutes if it’s straight from the fridge. Your future self will thank you when the dough comes together smoothly without extra flour.
- CHILL THE DOUGH: Skipping this step leads to sad, flat biscuits. Wrap the dough in plastic and refrigerate for at least 30 minutes before rolling. The cold makes it easier to handle and prevents the peanut butter from melting into a greasy mess during baking.
- CUT THIN, BAKE LOW: Thick biscuits chew up like hockey pucks. Roll the dough to ¼-inch thickness and cut with a sharp knife or cookie cutter. Bake at 325°F (not 350°F) for 20-25 minutes—lower heat ensures even cooking without burning the edges.
Make-ahead tips for this dish
Prep Ahead for Busy Days
Make a double batch of dough and store it in the refrigerator for up to 5 days or freeze for 3 months. I like to portion the dough into 4 equal balls, wrap each in plastic wrap, and freeze them flat on a tray.
Once frozen solid, transfer to a ziplock bag—this way, you can grab one whenever your pup needs a treat without thawing the whole batch. 🥶
Freeze Pre-Cut Biscuits
Cut out the biscuits as usual, but instead of baking them right away, place them on a parchment-lined tray and freeze for 1 hour. Then transfer to a ziplock bag or airtight container.
When you're ready to bake, simply pop them straight from the freezer into a 375°F oven and add 2-3 extra minutes to the baking time. This method keeps them extra crispy! ❄️
Batch Baking for Training
If you're training your pup, bake a large batch and store them in small portions for easy access. I use mini muffin tins to bake bite-sized treats—just reduce the dough to 1 tbsp per cup and bake for 10-12 minutes.
Store in silicone treat bags for quick grab-and-go rewards. These stay fresh for 1 week at room temperature. 🐾
Revive Stale Biscuits
If your biscuits lose their crunch, don’t toss them! Pop them in a single layer on a baking sheet and bake at 300°F for 3-5 minutes to restore crispiness.
For extra flavor, brush with a little olive oil before reheating. This trick works like magic—your dog won’t even notice they’ve been sitting around! 🔥
Portion for Meal Prep
Divide cooled biscuits into small containers (like 3-ounce mason jars) for easy serving. I label each with the date and store them in the pantry. This way, you can grab a handful for car rides, vet visits, or as a training reward without digging through a big container.
Keep portions dog-sized—about 1-2 biscuits per 20 lbs of body weight per day. 📅
Customize for Special Occasions
Make themed biscuits for holidays! Add a sprinkle of dog-safe shredded coconut for a tropical twist or a pinch of turmeric for a golden hue. For birthdays, cut out bone shapes or use a cookie cutter to make paw prints.
Store these in decorative treat boxes to keep them fresh and festive. Your pup will feel like the star of the show! 🎉

Frequently asked questions
Can I use pumpkin instead of sweet potato?
Yes! You can substitute 1 cup unsweetened pumpkin puree for the sweet potato—it works perfectly and adds extra fiber. Just make sure it's plain canned pumpkin (no spices or additives) and measure carefully to maintain the right dough consistency.
Why do my biscuits turn out gummy instead of crispy?
Gummy biscuits usually happen when the dough is too thick or the oven isn't hot enough. Try rolling the dough slightly thinner (1/16-inch) and preheating your oven to 375°F instead of 350°F. Bake for 10-12 minutes instead of 15 to get that perfect crisp edge.
Is it safe to give these to puppies?
These biscuits are great for puppies in moderation! Just serve 1/4 of a biscuit per 10 lbs of body weight as a training treat. Puppies under 4 months should avoid peanut butter (even xylitol-free) due to their sensitive digestive systems—use pumpkin puree instead for their first treats.
Can I make these without an egg?
For a vegan version, replace the egg with a flax egg (1 tbsp ground flaxseed + 3 tbsp water, mixed and rested for 5 minutes). The dough will be slightly stickier, so you may need an extra 1 tbsp flour to handle it. The texture comes out just as good!
How do I store leftovers for maximum freshness?
Store cooled biscuits in an airtight container at room temperature for up to 2 weeks. For longer storage, freeze them in a single layer on a tray first, then transfer to a bag. When ready to serve, thaw at room temperature for 10 minutes—no microwave needed!
