Sweet Potato Cornbread Recipe (Moist & Easy)

This Sweet Potato Cornbread combines roasted sweet potato, buttermilk, brown sugar, cinnamon, and nutmeg for a moist, tender cornbread with crisp golden edges.

Bake it in a hot cast iron skillet for that classic crust, then serve it warm with butter alongside chili, collard greens, ham, or your Thanksgiving dinner.

Sweet potato and cornbread just make sense together. The sweet potato adds moisture and a little natural sweetness without turning the bread into cake, while the cornmeal keeps it firmly in cornbread territory.

I especially love this one during fall and the holidays because it fits right onto the same table as Southern Collard Greens, Coca-Cola Ham, and Easy Candied Yams.

Ingredients You'll Need

See the recipe card below for exact measurements.

• Sweet potato: You'll need 1½ cups cooked and mashed sweet potato. Roasting gives you concentrated flavor without adding extra water to the batter.
• All-purpose flour: Provides enough structure to help the cornbread hold together.
• Yellow cornmeal: Fine-ground yellow cornmeal gives you classic cornbread flavor without an overly coarse texture.
• Brown sugar: Adds a mild caramel sweetness. Either light or dark brown sugar works.
• Baking powder: Provides the lift for this cornbread. Make sure yours is fresh for the best rise.
• Cinnamon and nutmeg: These warm spices pair naturally with sweet potato while still allowing the cornmeal flavor to come through.
• Butter: Work room-temperature butter into the dry ingredients until the mixture resembles coarse crumbs.
• Egg: Helps bind the batter and adds structure.
• Buttermilk: Adds moisture, richness, and a light tang that balances the sweetness.
• Vegetable oil: Used to coat and preheat the cast iron skillet for crisp edges.

How to Make Sweet Potato Cornbread

Here's the quick overview. The recipe card below contains the complete measurements and instructions.

1. Roast the Sweet Potatoes

Roast halved sweet potatoes until completely tender, then scoop out the flesh and mash it until smooth.

Measure out 1½ cups for the cornbread.

2. Preheat the Skillet

Heat the oven to 400°F.

Add the vegetable oil to a 10-inch cast iron skillet and place it in the oven while you prepare the batter.

3. Mix the Dry Ingredients

Whisk together the flour, cornmeal, brown sugar, baking powder, cinnamon, nutmeg, and salt.

Work the room-temperature butter into the mixture until it resembles coarse crumbs.

4. Mix the Wet Ingredients

Stir together the mashed sweet potato, egg, and buttermilk until well combined.

5. Combine

Fold the wet mixture into the dry ingredients just until no dry streaks remain.

The batter will be thick. Don't keep mixing in an attempt to make it perfectly smooth.

6. Bake

Carefully pour the batter into the hot skillet and spread it evenly.

Bake until the top is golden, the edges are crisp, and a toothpick inserted into the center comes out clean or with a few moist crumbs.

Let it rest for about 10 minutes before slicing.

LaKita's Expert Tips

• Measure the mashed sweet potato. Sweet potatoes vary a lot in size, so use the measured 1½ cups rather than guessing by number of potatoes.
• Roast instead of boiling when possible. Roasting avoids adding extra water and gives the sweet potato more concentrated flavor.
• Preheat the skillet. Hot oil helps create those crisp golden edges.
• Don't overmix. Stir only until the wet and dry ingredients come together.
• Check at 35 minutes. Sweet potato keeps this bread moist, so avoid baking longer than necessary.
• Let it rest. Ten minutes gives the crumb time to settle before slicing.
• Use oven mitts. That skillet handle is just as hot as the pan itself. Ask me how easy that is to forget. 😂

How to Roast Sweet Potatoes for Cornbread

Heat the oven to 400°F.

Scrub the sweet potatoes and cut them in half lengthwise. Place them cut-side down on a parchment-lined baking sheet.

Roast for about 30 minutes, or until a fork slides easily through the center.

Let them cool enough to handle, scoop out the flesh, and mash until smooth.

You can roast the sweet potatoes ahead and refrigerate the mashed flesh until you're ready to bake.

Make-Ahead Instructions

Sweet potato cornbread works well for holiday prep.

Roast the Sweet Potato Ahead

Roast and mash the sweet potato up to 3 days ahead.

Store it covered in the refrigerator until you're ready to bake.

Bake the Cornbread Ahead

Bake the cornbread 1 to 2 days before serving.

Allow it to cool completely, wrap it well, and store it until you're ready to serve.

I do not recommend mixing the batter ahead because the baking powder begins working once the ingredients are combined.

For Thanksgiving, I would rather bake the entire cornbread the day before and simply warm it before dinner.

Storage and Reheating

Room Temperature

Once completely cooled, keep the cornbread tightly covered at room temperature for up to 2 days.

Refrigerator

For longer storage, place it in an airtight container in the refrigerator for up to 4 days.

Freezer

Wrap individual slices tightly and place them in a freezer-safe container or bag.

Freeze for up to 1 month for the best texture.

Thaw overnight in the refrigerator or at room temperature.

Reheating

For several slices, wrap them loosely in foil and warm in a 300°F oven for about 10 to 15 minutes.

For one slice, microwave briefly until warm.

For crispy edges, warm a slice in a buttered skillet over medium-low heat.

How to Keep Sweet Potato Cornbread Moist

Three things matter most:

Don't overmeasure the flour or cornmeal. Spoon dry ingredients into measuring cups and level them rather than packing them down.

Don't overmix the batter. Stop as soon as the dry streaks disappear.

Don't overbake it. Begin checking at 35 minutes.

The finished cornbread should be fully baked but still tender when you cut into it.

Why Is My Sweet Potato Cornbread Dense?

A dense loaf can happen if:

• The baking powder is old.
• Too much sweet potato was added.
• The batter was overmixed.
• The dry ingredients were overmeasured.
• The cornbread needed a few more minutes in the oven.

Measure carefully and use the visual doneness cues rather than relying only on the clock.
