Sweet potato cake is the kind of dessert that tastes like comfort rather than sugar, the mash whipped until it is almost like frosting. I add a little butter at the end so the flavor stays round instead of flat.
The recipe is simple to follow and introduces a wonderful balance of flavors and textures, making it a perfect choice for anyone looking to explore Korean desserts.
Korean Sweet Potato Cake Recipe

This Korean Sweet Potato Cake features a soft and moist cake layered with a creamy filling made from sweet potato. With a cooking time of about 1 hour, this delightful dessert serves 8 people and brings a touch of Korean culinary tradition to your table.
Ingredients
- 2 cups Korean sweet potatoes, peeled and steamed
- 1 ½ cups all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- ¾ cup sugar
- ½ cup unsalted butter, softened
- 3 large eggs
- 1 teaspoon vanilla extract
- 1 cup heavy cream, whipped
- Additional sweet potato for decoration (optional)
Instructions
- Prepare the Sweet Potatoes: Steam the Korean sweet potatoes until tender, about 20 minutes. Allow to cool, then mash and set aside.
- Mix the Dry Ingredients: In a bowl, whisk together flour, baking powder, baking soda, and salt until well combined.
- Cream the Butter and Sugar: In a large bowl, beat the softened butter and sugar together until light and fluffy. Add the eggs one at a time, mixing well after each addition, followed by the vanilla extract.
- Combine Ingredients: Gradually add the dry ingredients to the butter mixture, alternating with the mashed sweet potato until just combined.
- Bake the Cake: Preheat the oven to 350°F (175°C). Pour the batter into a greased cake pan and bake for 30-35 minutes or until a toothpick comes out clean. Let it cool completely.
- Prepare the Cream: In a separate bowl, whip the heavy cream until soft peaks form. Gently fold in some of the mashed sweet potato into the whipped cream for flavor and color.
- Assemble the Cake: Once the cake is cool, layer the whipped sweet potato cream between the cake layers. Top the cake with remaining cream and decorate with additional sweet potato if desired.
- Chill and Serve: Refrigerate the cake for at least an hour before slicing. Serve chilled and enjoy!
