Sweet Potato Skillet Cake with Toasted Brown Sugar is the kind of dessert that feels warm, comforting, and unforgettable from the very first bite. Made with naturally sweet mashed sweet potatoes, rich butter, fragrant spices, and a caramel-like brown sugar topping, this rustic cake is baked in a skillet for crisp golden edges and a soft, moist center. It’s perfect for autumn gatherings, holiday dinners, or anytime you want a homemade dessert with old-fashioned charm.
The sweet potato gives the cake a tender texture and deep flavor, while cinnamon and nutmeg add warmth in every slice. Baking it in a cast-iron skillet creates beautiful browning around the edges and helps the toasted brown sugar topping melt into a glossy, buttery crust. Serve it warm with whipped cream, vanilla ice cream, or simply on its own with coffee or tea.
Ingredients
For the Cake:
- 1 cup mashed cooked sweet potato
- 1 cup all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon cinnamon
- 1/4 teaspoon nutmeg
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, softened
- 3/4 cup brown sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/3 cup milk
For the Toasted Brown Sugar Topping:
- 1/2 cup brown sugar
- 2 tablespoons butter, melted
- 1 tablespoon heavy cream or milk
- 1/4 teaspoon cinnamon
- 1/4 cup chopped pecans or walnuts (optional)
Instructions
Begin by preheating your oven to 350°F (175°C). Grease a 10-inch cast-iron skillet or oven-safe baking pan with butter.
In a medium bowl, whisk together the flour, baking powder, baking soda, cinnamon, nutmeg, and salt. Set aside.
In a large mixing bowl, beat the softened butter and brown sugar until light and fluffy. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract and mashed sweet potato until smooth.
Gradually add the dry ingredients to the wet mixture, alternating with the milk. Mix until just combined. Do not overmix.
Spread the batter evenly into the prepared skillet.
To make the topping, combine brown sugar, melted butter, cream, cinnamon, and nuts if using. Sprinkle or spoon evenly over the batter.
Bake for 35 to 45 minutes, or until the center is set and a toothpick inserted comes out clean. The topping should be bubbling and caramelized.
Allow the cake to cool for 10 minutes before serving.
Serving Suggestions
Serve warm directly from the skillet for a cozy presentation. Add a scoop of vanilla ice cream for a rich contrast, or drizzle with maple syrup for extra indulgence. A dollop of whipped cream and a dusting of cinnamon also pair beautifully.
Tips for Best Results
Use freshly roasted or boiled sweet potatoes mashed until smooth for the best texture. If canned sweet potato puree is used, make sure it is plain and unsweetened. Do not overbake, as the cake should remain soft and moist inside.
Storage
Cover leftovers tightly and store at room temperature for up to 2 days or refrigerate for up to 5 days. Reheat slices in the microwave for a warm, fresh-from-the-oven taste.
Final Thoughts
Sweet Potato Skillet Cake with Toasted Brown Sugar is a comforting dessert that combines rich southern flavor with simple homemade goodness.
