Ingredients for sweet potato biscuit recipe buttermilk
Sweet potato puree, buttermilk, and cold butter—these are the magic trio for flaky, golden biscuits.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potato Puree 🍠 | ½ cup | Homemade or canned, unsweetened |
| All-Purpose Flour 🌾 | 3 cups | Sifted for light texture |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for flakiness |
| Buttermilk 🥛 | 1 cup | Full-fat for richness |
| Granulated Sugar 🍚 | 1 ½ tbsp | Balances sweetness |
| Baking Powder 🧂 | 2 ½ tsp | Diamond Crystal preferred |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Garlic Powder 🧄 | ½ tsp | For subtle depth |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Honey Butter 🍯 | ¼ cup | For serving (optional) |
The sweet potato puree is non-negotiable here. Canned unsweetened works in a pinch, but homemade—just boil, peel, and blend—gives that restaurant-quality depth. Trader Joe's sells a great pre-made version if you're short on time. For the butter, cold is critical—cut it into small cubes and keep it chilled until the last minute. The buttermilk? Full-fat is worth it—it adds richness that regular milk can't match. And if you're using store-bought, shake the carton first—settled buttermilk loses its tang.
No buttermilk? Mix 1 tbsp lemon juice or vinegar with 1 cup milk and let it sit for 5 minutes. Short on sweet potato? Substitute 1/4 cup pumpkin puree—it's close but not identical. The baking powder matters too—Diamond Crystal is lighter than other brands, so if that's not available, add an extra 1/4 tsp. For the honey butter, any honey will do, but local raw honey adds a nice floral note. And if you're feeling fancy, add a pinch of cinnamon to the dough—it pairs perfectly with the sweet potato.
These biscuits are best served fresh out of the oven, but they reheat beautifully. Wrap them in foil and pop in a 350°F oven for 5-10 minutes to restore that crispy crust. Store leftovers in an airtight container at room temperature for 2 days or freeze for up to 3 months. For freezing, wrap individually in plastic—it keeps them from getting soggy. And if you're making a big batch, freeze the dough before baking. Just shape, freeze, and bake straight from frozen—add 2-3 minutes to the cook time.

Step-by-step instructions for sweet potato buttermilk biscuits
Here's how to create tender, flaky biscuits with that perfect golden crust.
Mix the Wet Ingredients
In a medium bowl, combine the 0.5 cup sweet potato puree with the 1 cup buttermilk. Stir gently until fully blended—this creates the base for our moist, flavorful dough. The sweet potato adds natural sweetness and moisture while keeping the biscuits tender.
In a separate small bowl, whisk together the 0.75 cup cold unsalted butter (leave it cubed) with the 1.5 tbsp granulated sugar, 0.5 tsp garlic powder, and 0.5 tsp black pepper. This butter mixture will create those signature flaky layers when folded into the dough. Keep this bowl cold while you prepare the dry ingredients.
Combine Dry Ingredients
In a large bowl, sift together the 3 cups all-purpose flour, 2.5 tsp baking powder, and 1 tsp salt. Sifting ensures an even distribution of ingredients and prevents lumps in your biscuits. Use a whisk to break up any remaining clumps—this step is crucial for light, airy texture.
Make a well in the center of the dry ingredients and pour in the wet ingredients mixture. Using a wooden spoon or silicone spatula, gently fold everything together just until combined. Avoid overmixing—you should still see some dry flour streaks. The dough will be sticky but should come together when pressed.
Cut in the Cold Butter
Add the cold butter mixture to the flour mixture and use a pastry cutter or your fingers to work it into the dough. Cut in the butter until you have pea-sized pieces throughout—this creates those beautiful flaky layers. The butter should be cold enough to hold its shape when pressed.
Here's the thing—if the dough feels too warm or sticky, pop it in the refrigerator for 10-15 minutes to firm up. Cold butter is your secret weapon for achieving that signature flakiness. When the dough is ready, turn it out onto a lightly floured surface and gently shape it into a rectangle about 1-inch thick.
Fold and Shape the Dough
Fold the dough rectangle in thirds like a letter, pressing gently to seal the edges. Rotate the dough 90 degrees and repeat this folding process two more times. This technique creates multiple layers of butter, ensuring maximum flakiness when baked. After folding, flatten the dough again to about 1-inch thickness.
Now for the fun part—cut out your biscuits. Use a 2.5-inch round cutter (or a glass of that size) to cut out circles. Press straight down and twist slightly to release the biscuits cleanly. Place them on a parchment-lined baking sheet, spacing them about 1 inch apart—they'll expand as they bake.
Bake to Golden Perfection
Preheat your oven to 425°F. Bake the biscuits for 12-15 minutes until they're deep golden brown on top and the edges look set. The centers should still be slightly soft—this ensures they remain tender. Don't overbake, or they'll turn tough.
For serving, brush the warm biscuits with melted honey butter while they're still hot. The butter will melt into those flaky layers, adding a sweet, rich finish. These biscuits are best enjoyed immediately while they're warm and tender—perfect for soaking up gravy or pairing with honey.
Pro Tips For Making Sweet Potato Biscuit Recipe Buttermilk
- STORE BUTTERMILK COLD: Use straight-from-the-fridge buttermilk—room temperature makes biscuits dense and gummy. I learned this the hard way after a batch turned out like hockey pucks.
- WEIGH THE FLOUR: Spoon flour into your measuring cup, then level it off—don’t scoop directly from the bag. Packed cups add too much, and your biscuits will be heavy instead of light and fluffy.
- DON’T OVERMIX: Stop stirring once the dough comes together—just 2-3 turns after the flour disappears. Overworking it turns sweet potato biscuits into tough, sad crackers.
- USE COLD BUTTER: Cut the butter into pea-sized chunks and fold it in last—don’t melt it first. Cold butter creates flaky layers, and skipping this step means you’ll get a dense, cake-like biscuit instead.
Creative variations of this dish
Sweet Potato Swap
Trade the sweet potato puree for ½ cup mashed roasted beets to add earthy depth and vibrant color. The natural sweetness of beets complements the buttermilk beautifully, creating biscuits with a subtle pink hue.
I’ve tested this variation and found it works best with 1 tsp cinnamon added to the dry ingredients for warmth. 🍠➡️🍠
Cheesy Twist
Fold in ½ cup shredded sharp cheddar or Monterey Jack when mixing the dough for a gooey, melty center. The cheese pairs perfectly with the sweet potato’s natural sweetness, creating a biscuit that’s both savory and slightly sweet.
For extra richness, use 2% milk instead of buttermilk in the wet ingredients—it adds creaminess without overpowering the tang.
Herb-Infused Version
Add 1 tbsp fresh rosemary or thyme leaves to the dough for an aromatic twist. These herbs brighten the sweet potato’s earthiness while keeping the biscuits tender. I recommend finely chopping the herbs and mixing them into the butter before cutting it into the flour.
A pinch of lemon zest in the dry ingredients adds a citrusy lift that cuts through the richness.
Gluten-Free Adaptation
Replace the all-purpose flour with a 1:1 gluten-free baking flour blend like Bob’s Red Mill or King Arthur. Add ½ tsp xanthan gum to the dry ingredients to mimic the structure of traditional biscuits.
The sweet potato puree and buttermilk still work wonders here, but expect a slightly denser texture. Brush the baked biscuits with melted butter mixed with honey to compensate for any dryness.
Spiced Pumpkin Spice
Swap the sweet potato for ½ cup pumpkin puree and add 1 tsp pumpkin pie spice to the dry ingredients. This fall-inspired variation keeps the buttermilk’s tang while introducing warm spices like cinnamon, nutmeg, and cloves.
The result? Biscuits that taste like a cross between a classic biscuit and a spiced pumpkin muffin. Serve with a drizzle of maple syrup for a cozy breakfast treat. 🍂

Frequently asked questions
Can I use canned sweet potato instead of fresh?
Yes! Unsweetened canned sweet potato puree works perfectly—just drain it well to avoid excess moisture. For homemade, boil 1 medium sweet potato, peel it, and blend until smooth. The texture difference is minimal, but fresh adds slightly more depth of flavor.
Why does my dough keep sticking to my hands?
Sticky dough happens when the butter melts too quickly or the flour isn't sifted properly. Keep everything cold (including your work surface) and flour your hands lightly. If it's still sticky, chill the dough for 10-15 minutes before shaping. The buttermilk and sweet potato puree naturally add moisture, so don't overcompensate with extra flour—just handle it gently!
Can I make these biscuits ahead of time?
Shape the biscuits, wrap them tightly in plastic, and freeze for up to 3 months. Bake straight from frozen at 425°F for 15-18 minutes, adding 2-3 minutes to the cook time. For reheating, warm in a 350°F oven for 5-10 minutes to restore that crispy crust. They won't be quite as flaky when reheated, but they'll still be delicious!
What's the best way to store leftover biscuits?
Store in an airtight container at room temperature for 2 days or freeze for up to 3 months. To prevent sogginess, place parchment paper between layers. For serving, reheat in a 350°F oven for 5 minutes or toast in a skillet with a little butter for that fresh-baked taste.
Can I substitute buttermilk with something else?
Yes! Mix 1 tbsp lemon juice or vinegar with 1 cup milk and let it sit for 5 minutes to mimic buttermilk's tang. For extra richness, use 2% milk instead of whole milk. Avoid almond milk—it lacks the fat and acidity needed for proper texture and flavor. The buttermilk's acidity helps activate the baking powder for that perfect rise!
