How to Make Sweet Potato Honeybun Cake with Pecans & Grated Sweet Potato Icing
Step 1: Prepare the Pan and Preheat
Set yourself up for success by preheating your oven to 350°F (175°C) and generously greasing and flouring a 9×13-inch baking pan. This ensures the Sweet Potato Honeybun Cake with Pecans & Grated Sweet Potato Icing releases cleanly, showing off those beautiful swirls.
Step 2: Mix the Cake Batter
In a large mixing bowl, combine the box of yellow cake mix, mashed sweet potato, eggs, sour cream, vegetable oil, honey, cinnamon, and nutmeg. Stir until the batter is smooth and evenly blended. Fold in the chopped pecans, making sure every bite will get a little crunch.
Step 3: Make the Filling
In a separate small bowl, stir together the brown sugar, cinnamon, and chopped pecans for the ultimate honeybun swirl. This filling will nestle into the center of your cake, creating a gooey, spiced surprise.
Step 4: Assemble the Cake
Pour half of the batter into your prepared pan, spreading it into an even layer. Sprinkle the entire filling mixture evenly over the top. Spoon the remaining batter over and gently spread so it covers the filling. Take a butter knife and swirl the layers lightly, so you get a ribbon effect without fully mixing them together.
Step 5: Bake
Place your pan in the oven and bake for 35 to 40 minutes. To test for doneness, insert a toothpick into the center—if it comes out clean or with just a couple of moist crumbs, you’re ready! Let your Sweet Potato Honeybun Cake with Pecans & Grated Sweet Potato Icing cool slightly in the pan to make icing a breeze.
Step 6: Make the Grated Sweet Potato Icing
Melt the butter in a small saucepan over medium heat. Add the grated sweet potato and cook while stirring for about 2-3 minutes, just until slightly softened—it should still have a bit of texture. In a mixing bowl, whisk together powdered sugar, milk, vanilla, and a pinch of salt until smooth. Stir in your cooked grated sweet potato, then adjust with a splash of milk if needed for the perfect spreadable consistency.
Step 7: Ice and Finish
Spread the icing generously over your warm cake, letting it gently melt into the nooks and crannies. For the best Sweet Potato Honeybun Cake with Pecans & Grated Sweet Potato Icing experience, allow the icing to set before slicing and serving.

Make Ahead and Storage
Storing Leftovers
Keep your Sweet Potato Honeybun Cake with Pecans & Grated Sweet Potato Icing covered at room temperature for up to two days, or pop it in the refrigerator for four to five days. The icing keeps the cake moist, but be sure the pan is tightly wrapped to lock in freshness.
Freezing
If you want to make the whole cake ahead, you can freeze it (either iced or plain) by wrapping individual slices or the entire pan tightly in plastic wrap and then foil. Thaw overnight in the fridge—this cake holds its texture beautifully, so you can enjoy a taste of autumn any time you crave it.
Reheating
For that fresh-from-the-oven coziness, warm slices in the microwave for about 20 seconds or pop the whole pan into a low oven until just heated through. The icing will get a little melty and luscious—exactly how it should be for the perfect Sweet Potato Honeybun Cake with Pecans & Grated Sweet Potato Icing experience.
FAQs
Can I use homemade cake mix instead of boxed?
Absolutely! If you prefer a from-scratch approach, replace the boxed cake mix with your favorite homemade yellow cake batter. Just make sure to adjust for sweetness and leavening so the Sweet Potato Honeybun Cake with Pecans & Grated Sweet Potato Icing rises properly and retains the right sweetness.
How do I get the smoothest grated sweet potato for the icing?
For a super-smooth icing, use the finest holes on your box grater or food processor attachment. If you’d like some extra texture and visual appeal, a coarser grate is lovely too. The sweet potato will soften further as it cooks with the butter.
Can I make this cake nut-free?
You can absolutely leave out the pecans if allergies are a concern. The Sweet Potato Honeybun Cake with Pecans & Grated Sweet Potato Icing will still have plenty of flavor and moisture; try adding a handful of raisins or a sprinkle of oats for a different twist if you like.
What makes this different from a regular honeybun cake?
