Cast-Iron Sweet Potato Sticky Biscuit Rolls with Sorghum Caramel & Toasted Pecans
Sunday mornings at my grandmother Miss Pearl's Atlanta table always smelled like baking sweet potatoes and dark sorghum syrup. I can still picture her flour-dusted apron and the way her hands moved like lightning over the wooden board, turning out biscuits so light they practically floated. Years later, working the line in Charleston, I found myself craving those slow mornings and wondering how to elevate that comforting memory. That is how these sticky rolls were born. I took my grandmother's transcendent sweet potato biscuit dough, rolled it up with warm autumn spices, and nested the spirals right into a cast-iron skillet bubbling with buttery sorghum caramel and toasted pecans. Baking them in cast iron is the secret—it gives you those crackling, deeply caramelized edges while keeping the centers melt-in-your-mouth tender. This recipe is deeply special to me because it bridges the gap between my childhood memories and the modern technique I learned along the way. If you want to make it your own, try swapping the pecans for toasted hazelnuts or steep a little fresh rosemary in your sorghum caramel for an unexpected herbal note. Pour yourself some strong coffee, pull up a chair, and taste a little piece of my history.

Instructions
- 1
Position a rack in the center of your oven and preheat to 400°F (200°C). In a small bowl, whisk together 1 cup roasted sweet potato puree, 0.75 cup whole buttermilk, and 1 tsp pure vanilla extract until completely smooth and velvety. Place the bowl in the refrigerator to stay thoroughly chilled.
5 min
Tip: Keeping your wet ingredients ice-cold is the secret to soaring, flaky biscuit layers.
- 2
In a 10-inch well-seasoned cast-iron skillet set over medium-low heat, melt 4 tbsp unsalted butter. Whisk in 0.33 cup Southern sorghum syrup, 0.75 cup dark brown sugar, 0.25 cup heavy cream, 0.5 tsp ground cinnamon, and 0.5 tsp kosher salt. Cook, whisking gently, for 3 minutes until the sugar dissolves and the caramel gently simmers. Remove the skillet from heat and scatter 1 cup pecan halves evenly across the caramel bed.
5 min
Tip: Do not let the caramel boil hard; you just want the granules melted so it creates a silky sauce under the rolls.
- 3
In a wide mixing bowl, whisk together 2.75 cups all-purpose flour, 1 tbsp baking powder, 0.5 tsp baking soda, 0.75 tsp kosher salt, 0.5 tsp ground ginger, and 0.5 tsp freshly grated nutmeg. Add 8 tbsp unsalted butter (frozen and grated) into the dry mixture. Use your fingertips to quickly toss the butter shreds through the flour until every shred is coated, without melting the fat.
6 min
Tip: Grating frozen butter on the large holes of a box grater guarantees cold, even pockets of steam when baking.
- 4
Pour the chilled sweet potato-buttermilk mixture into the flour bowl. Stir gently with a rubber spatula just until a soft, shaggy dough pulls together. Turn the dough out onto a lightly floured work surface and gently pat into a rough rectangle. Fold it like a business letter in thirds, rotate 90 degrees, and repeat once more to develop distinct buttery strata.
5 min
Tip: Handle the dough with a light, confident touch—overworking develops gluten and toughens biscuits.
- 5
Gently roll the laminated dough into a 10-by-14-inch rectangle about 1/2-inch thick. Brush the surface with 2 tbsp unsalted butter (melted) and 0.5 tsp pure vanilla extract. In a small cup, mix 0.5 cup dark brown sugar with 1.5 tsp ground cinnamon, then sprinkle it evenly across the buttered dough, leaving a 1/2-inch border along the far long edge.
5 min
Tip: A pastry brush helps spread the melted butter evenly without tearing the tender dough.
- 6
Starting from the long edge closest to you, roll the dough into a snug, even log. Using a sharp serrated knife or unflavored dental floss, slice the log crosswise into 8 equal, thick rounds. Gently nestle the rolls cut-side up into the warm caramel and pecan bed in the cast-iron skillet, spacing them evenly with one in the center and seven around the perimeter.
6 min
Tip: Slicing with dental floss looped under and crossed over prevents squishing the delicate biscuit spirals.
- 7
Transfer the skillet to the preheated oven and bake at 400°F for 26 to 28 minutes, until the tops of the biscuit rolls are deeply puffed, burnished golden brown, and the sorghum caramel is bubbling vigorously up around the edges.
28 min
Tip: Place a sheet of foil on the oven rack below just in case the bubbling sorghum syrup splashes over.
- 8
Carefully remove the skillet from the oven using heavy-duty oven mitts. Let the rolls rest in the skillet for exactly 5 minutes so the caramel slightly settles. Sprinkle the tops with 0.25 tsp flaky sea salt. Serve directly from the skillet warm, spooning extra sorghum-pecan caramel over each roll.
5 min
Tip: Serve warm within 20 minutes for peak flaky tenderness and crisp caramelized edges.
Chef's Notes
My grandmother Big Mama always roasted sweet potatoes whole in their skins until the sugars caramelized into sweet black beads on the pan; that deep roasted flavor is the heartbeat of this recipe. Unlike heavy yeast cinnamon buns that take hours to proof, biscuit dough rewards you with sky-high lift and lightning speed, letting you serve warm, bubbling heritage comfort on a crisp morning in under an hour.

Heritage recipes with a chef's touch
My grandmother's kitchen in Atlanta is where I learned that food carries history. Every pot of collards, every batch of biscuits, every Sunday roast told stories of resilience, family, and love. I went on to train at the finest restaurants in Charleston and worked my way up through white-tablecloth kitchens. But I always came back to those family recipes—now I cook them with a chef's technique but a grandmother's heart. Because the best food honors where it came from.
