How to Make Sweet Potato Honeybun Cake with Pecans & Grated Sweet Potato Icing Recipe
Step 1: Prepare Your Pan and Oven
Start by preheating your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan thoroughly. This ensures that your cake will bake evenly and come out cleanly without sticking, laying the foundation for a beautiful honeybun cake.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine the all-purpose flour, granulated sugar, baking powder, baking soda, ground cinnamon, and salt. Whisking these dry ingredients together not only ensures even distribution of flavors but also guarantees a light, airy texture throughout the cake.
Step 3: Combine Wet Ingredients and Make Batter
Add the softened unsalted butter, mashed cooked sweet potato, buttermilk, eggs, and vanilla extract into the dry mixture. Use a hand or stand mixer to blend everything until the batter is smooth and uniformly mixed. The mashed sweet potato enriches the batter with moisture and natural sweetness, while the butter adds a silky texture that makes every bite melt in your mouth.
Step 4: Prepare the Pecan Swirl
In a small bowl, mix the brown sugar, ground cinnamon, and 1/2 cup chopped pecans. This fragrant, buttery swirl will be the highlight that makes this cake so irresistible. It’s the perfect blend of sweetness and crunch that contrasts the tender cake beautifully.
Step 5: Assemble the Cake
Pour half of the cake batter into your prepared pan and smooth it out. Sprinkle the pecan swirl mixture evenly over the batter, then pour the remaining batter on top, gently spreading it to cover the swirl. This layering is what creates the signature honeybun effect, with sweet, spicy layers and nutty surprises in every bite.
Step 6: Bake and Add the Topping
Bake the cake in the preheated oven for about 35 to 40 minutes, or until a toothpick inserted into the center comes out clean. Once out of the oven, immediately sprinkle the remaining chopped pecans over the top to add a toasty, crunchy finish that enhances every forkful.
Step 7: Prepare the Grated Sweet Potato Icing
While the cake cools, combine grated sweet potato, powdered sugar, melted butter, vanilla extract, ground cinnamon, and enough milk to reach a drizzling consistency. This unique icing brings a fresh and creamy texture that elevates the entire cake and ties the sweet potato theme beautifully together.
Step 8: Ice the Cake
Once the cake has cooled to room temperature, drizzle the grated sweet potato icing evenly over the top. Let it set for a few minutes so the flavors meld and you’re ready for a slice of pure comfort and indulgence.
How to Serve Sweet Potato Honeybun Cake with Pecans & Grated Sweet Potato Icing Recipe

Garnishes
A generous sprinkle of toasted pecans or a small dollop of whipped cream can bring an extra layer of decadence to your presentation. Fresh herbs like a sprig of rosemary or a dusting of cinnamon powder make it visually striking and scent inviting.
Side Dishes
This cake pairs wonderfully with a cup of spiced chai tea, creamy vanilla ice cream, or even a scoop of cinnamon-swirled yogurt. These sides harmonize beautifully with the sweet potato and pecan flavors, enhancing the experience without overpowering it.
Creative Ways to Present
If you want to wow your guests, serve individual slices topped with toasted pecan halves and a drizzle of warm caramel sauce. You could even cut small squares and create a layered mini-trifle using whipped cream and crushed pecans for a playful twist on the classic cake.
Make Ahead and Storage
Storing Leftovers
Store the leftover cake tightly covered in the refrigerator for up to 3 days. It stays moist and flavorful, with the icing softening beautifully as it sits.
Freezing
You can freeze the unfrosted cake layers wrapped in plastic wrap and foil for up to 2 months. Thaw fully before adding the grated sweet potato icing for the best texture and flavor.
Reheating
Warm individual slices in the microwave for 20-30 seconds to bring back the homemade, just-baked feel. Adding a touch of butter or serving with warm milk or cream enhances the fresh-from-the-oven sensation.
FAQs
Can I use canned sweet potato instead of fresh?
While fresh sweet potatoes give the best flavor and texture, you can substitute canned sweet potato purée in the cake batter in equal amounts. However, for the grated sweet potato icing, fresh is key to achieve the right texture and freshness.
Is this cake gluten-free friendly?
This particular recipe calls for all-purpose flour, which contains gluten. If you want to make it gluten-free, consider substituting with a trusted gluten-free flour blend and adjust moisture as needed.
Can I make this cake vegan?
To make this cake vegan, swap the butter with plant-based margarine, replace eggs with flax eggs or chia eggs, and use a plant milk variety instead of buttermilk. The pecan swirl and grated sweet potato icing will still shine beautifully.
What is the best way to cook sweet potatoes for this recipe?
The best method is to boil or roast sweet potatoes until tender and then mash them smoothly. This brings out the sweetness and helps integrate them perfectly into the cake batter.
Can I add other nuts or toppings?
Absolutely! Walnuts or almonds would work wonderfully in place of pecans for the swirl or topping, and a sprinkle of shredded coconut or a drizzle of maple syrup on top adds delightful flavor variations.

Instructions
- Prepare the Cake Pan: Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan thoroughly to ensure the cake releases easily after baking.
- Mix Dry Ingredients: In a large mixing bowl, whisk together 2 cups all-purpose flour, 1 cup granulated sugar, 1 teaspoon baking powder, 1 teaspoon baking soda, 1 teaspoon ground cinnamon, and 1/2 teaspoon salt until evenly combined.

Using a hand mixer or stand mixer, beat the mixture on medium speed until smooth and well incorporated to form the cake batter.
- Prepare the Swirl Mixture: In a separate bowl, mix together 1/2 cup chopped pecans, 1/2 cup packed brown sugar, and 1 tablespoon ground cinnamon. This mixture will be used to create a delicious swirl inside the cake.
- Assemble the Cake with Swirl: Pour half of the prepared batter into the greased pan. Sprinkle half of the pecan and brown sugar mixture evenly over the batter. Add the remaining batter on top, then sprinkle the remaining swirl mixture over it. Use a knife or skewer to gently swirl the pecan mixture through the batter for a marbled honeybun effect.

Add milk 1 tablespoon at a time, stirring until the icing reaches a smooth, spreadable consistency.

Notes
- Substitute buttermilk with regular milk plus 1 tsp lemon juice or vinegar for a similar tang in the cake.
- Ensure the sweet potato used in the batter is fully cooked and mashed smoothly to avoid lumps.
- The grated sweet potato icing adds a unique texture and freshness; if unavailable, a simple cinnamon powdered sugar glaze can be used as an alternative.
- Store leftover cake covered at room temperature for up to 3 days or refrigerate for up to 5 days.
- For a nuttier flavor, toast the pecans before chopping and adding to the swirl and topping.
