Ingredients for sweet potato biscuit recipe buttermilk
Twelve golden biscuits with flaky layers and buttery crunch await—just eight ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 3 cups | Sifted for light texture |
| Granulated Sugar 🍚 | ¼ cup | White or light brown |
| Baking Powder 🧂 | 2 tbsp | Diamond Crystal preferred |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Cold Unsalted Butter 🧈 | ¾ cup | Cut into small cubes |
| Cooked Sweet Potato 🍠 | 1 ½ cups | Mashed, no skin, cooled |
| Buttermilk 🥛 | 1 ½ cups | Room temperature preferred |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | For subtle heat |
The sweet potato is the star here, so pick a firm, vibrant orange variety—like Yukon Gold or Jewel. Roast or boil until tender, then mash it smooth. Costco or Trader Joe's often carry pre-cooked sweet potatoes in the canned goods aisle if you're short on time. The buttermilk? Homemade is best—mix 1.5 cups milk with 1.5 tbsp vinegar or lemon juice and let it sit for 5 minutes. For the flour, King Arthur or Gold Medal brands are my go-to—they handle high-moisture doughs like this one beautifully.
No buttermilk? Substitute with 1.5 cups plain yogurt or sour cream thinned with a splash of milk. The sweet potato can be swapped for mashed white potato if you're in a pinch, but you'll lose that caramelized depth. Running low on baking powder? Use 1.75 tbsp plus 1.5 tsp cream of tartar as a substitute. The butter must stay cold—cut it into small cubes and keep it in the freezer until ready to use. If your kitchen's warm, chill the dough for 15 minutes before shaping. And for the pepper? Freshly ground makes all the difference—pre-ground loses its punch quickly.
These biscuits keep well for 3 days at room temperature wrapped in a clean kitchen towel, or 1 week in the fridge. For longer storage, freeze shaped biscuits on a tray before transferring to a bag—up to 3 months. To reheat, warm in a 350°F oven for 5-7 minutes until golden. Pro tip: Brush the tops with melted butter before serving for extra richness. The secret to perfect biscuits? Don't overwork the dough—just handle it enough to bring it together.

Step-by-step instructions for sweet potato buttermilk biscuits
Here's the method for tender, flaky biscuits with perfect golden layers.
Mix Dry Ingredients for Light Texture
In a large mixing bowl, combine the 3 cups All-Purpose Flour, 0.25 cup Granulated Sugar, 2 tbsp Baking Powder, and 1 tsp Salt. Use a whisk to break up any flour clumps and distribute the ingredients evenly. I like to sift the flour first for an even lighter texture, but whisking works too. This dry mixture forms the structural foundation of your biscuits.
Next, stir in the 0.5 tsp Freshly Ground Black Pepper. The pepper adds subtle warmth that complements the sweet potato flavor beautifully. Make sure the pepper is evenly distributed throughout the flour mixture before moving to the next step. This ensures every bite has that gentle kick.
Cut in Cold Butter for Flaky Layers
Add the 0.75 cup Cold Unsalted Butter, cut into small cubes, to the dry ingredients. Using a pastry cutter or two forks, work the butter into the flour mixture until you achieve pea-sized crumbles. The butter should be completely incorporated but still visible as small pieces. This creates those coveted flaky layers when baked.
I press down gently on the butter pieces during this process—this prevents them from melting into the flour too quickly. The butter should maintain its shape while still being evenly distributed. If the mixture starts to look like wet sand, it's too warm. Place the bowl in the refrigerator for 5 minutes to chill before proceeding.
Combine Wet Ingredients for Moist Dough
In a separate bowl, whisk together the 1.5 cups Cooked Sweet Potato (cooled and mashed) and 1.5 cups Buttermilk. The sweet potato should be completely smooth with no lumps. Pour this wet mixture into the bowl with the dry ingredients. Using a wooden spoon or silicone spatula, gently fold everything together until just combined.
Here's the thing—don't overmix. You want to preserve the flaky texture created by the cold butter. Stop mixing as soon as the dough comes together. The dough will be slightly sticky, but that's normal. If it feels too wet, add 1-2 tablespoons more of the All-Purpose Flour until it holds together when pressed.
Shape and Cut for Perfect Biscuits
Turn the dough out onto a lightly floured surface and gently pat it into a 1-inch thick rectangle. I use my hands, dusted with flour, to shape it evenly. Fold the rectangle in half like a book, then fold it in half again to create a compact block. This helps maintain the structure when cutting.
Using a 2.5-inch biscuit cutter, press straight down through all layers to cut out biscuits. Don't twist the cutter—this keeps the layers intact. Place each biscuit on a parchment-lined baking sheet, spacing them about 1 inch apart. If you have leftover dough scraps, gently press them together and cut out one more biscuit.
Bake Until Golden and Flaky
Preheat your oven to 425°F. Bake the biscuits for 12-15 minutes until they're golden brown on top and the edges look set. You'll know they're done when they pull away slightly from the parchment paper. The centers should still feel soft—this ensures they stay tender.
For extra browning, I like to broil for 1-2 minutes at the end, watching carefully to avoid burning. Let the biscuits cool on a wire rack for 5 minutes before serving. This resting time allows them to set properly and prevents a gummy texture. Serve warm with honey butter or your favorite jam for the perfect combination of sweet and savory.
Pro Tips For Making Sweet Potato Biscuit Recipe Buttermilk
- Chill the Sweet Potato: DESCRIPTION: Don’t skip this—let your cooked and mashed sweet potato cool completely before mixing it into the dough. I learned this the hard way when my biscuits turned out dense and gummy. Warm sweet potato adds moisture in all the wrong ways, and you’ll end up with a sad, flat biscuit instead of a tender, fluffy one.
- Cut Butter in Small Batches: DESCRIPTION: Work with 1-2 tablespoons of cold butter at a time when cutting it into the flour mixture. This isn’t the prettiest method, but it’s the tastiest—it guarantees even distribution and prevents the butter from melting into a greasy mess. (Yes, even if you’re impatient like me.)
- Measure Flour Correctly: DESCRIPTION: Spoon the flour into your measuring cup, then level it off with a knife—don’t scoop directly from the bag. Packing it down or overfilling the cup throws off the ratio, and your biscuits will either be tough or fall apart. This small step makes a real difference in texture.
- Don’t Overmix the Dough: DESCRIPTION: Stir the dough just until the flour is mostly incorporated—lumps are fine. Overmixing develops the gluten, and your biscuits will turn out dense instead of light and crumbly. My grandmother swore by this, and she was right: less handling = better biscuits.
Make-ahead tips for this dish
Prep Ahead Basics
Make the dough up to 24 hours ahead and store it tightly wrapped in plastic in the fridge. The cold temperature keeps the butter from melting and maintains the perfect texture.
When ready to bake, let the dough sit at room temperature for 15-20 minutes before shaping—this makes it easier to handle without sticking. I find this prep step especially helpful for busy mornings when I want fresh biscuits for brunch. 💪
Freezer-Friendly Dough
Shape the biscuits and freeze them on a parchment-lined tray for 1 hour to set, then transfer to a freezer bag with parchment between layers. This prevents sticking and makes them easy to grab later.
To bake from frozen, add 2-3 extra minutes to the cooking time—no thawing needed. I keep a stash of these in my freezer for lazy weeknights or last-minute guests. ✨
Baking Shortcuts
Preheat your oven while the biscuits are still in the fridge—this ensures even baking. For extra crispy tops, brush the biscuits with melted butter before baking. I like to use Land O'Lakes unsalted butter for this step.
If you're short on time, use a lightweight aluminum baking sheet instead of heavy steel—it heats up faster and bakes more evenly. 🔥
Reheating Perfection
Warm biscuits in a 350°F oven for 5-7 minutes with a splash of water in the pan to restore moisture. For microwave reheating, cover with a damp paper towel and heat in 20-second bursts until warm.
Avoid the microwave if you want crispy layers—it tends to make biscuits gummy. I always reheat mine in the oven for the best texture. 💫
Storage Secrets
Keep biscuits fresh at room temperature for 3 days wrapped in a clean kitchen towel to maintain softness. For longer storage, freeze shaped biscuits (unbaked) for up to 3 monthsquart-sized freezer bags and squeeze out excess air. Thaw in the fridge overnight before baking. 🧊

Frequently asked questions
Can I substitute regular milk for buttermilk in this recipe?
Not ideal, but you can! Mix 1.5 cups milk with 1.5 tablespoons lemon juice or vinegar, stir, then let sit for 5 minutes to curdle. This mimics buttermilk's tanginess and acidity, which helps activate the baking powder for flaky layers. For best results, use room-temperature milk.
Why did my sweet potato biscuits turn out dense instead of flaky?
Overmixing the dough or using warm butter are the most common culprits. The butter must stay cold when cutting into the flour, and you should stop mixing as soon as the dough comes together. Also, avoid pressing down on the biscuits when shaping—they should be gently placed on the baking sheet to maintain those air pockets.
How do I make these biscuits extra crispy on top?
Brush the tops with melted butter before baking, then broil for 1-2 minutes at the end. For even crispier results, bake on a preheated lightweight aluminum pan instead of heavy steel. The key is high heat at the end—just watch carefully to avoid burning!
Can I use canned sweet potatoes instead of fresh? Yes! Drain and mash 1 (15-ounce) can of sweet potatoes (like Libby's) until smooth. For extra flavor, add 1/4 teaspoon cinnamon to the dry ingredients. The texture will be slightly different but still delicious. Just
What's the best way to serve these sweet potato biscuits?
They're perfect with honey butter, maple syrup, or fresh berries for a sweet touch. For a savory option, try serving with fried chicken gravy or scrambled eggs. The subtle sweetness of the potato pairs beautifully with both sweet and savory flavors—just brush with melted butter before serving for extra richness!
