Ingredients You’ll Need
Getting the perfect balance of flavor and texture in this cake isn’t complicated at all. Each ingredient plays a crucial role: sweet potatoes add moisture and natural sweetness, spices create that signature warm aroma, and the cinnamon swirl brings a burst of sweetness and a little texture contrast that makes each slice unforgettable.
- 1 cup mashed sweet potatoes: The heart of the cake, bringing natural moisture and wholesome sweetness.
- 1 cup granulated sugar: Balances the earthiness of sweet potatoes with just enough sweetness – adjust to your taste.
- 1/2 cup packed brown sugar: Adds depth and a subtle caramel note that mellows the overall flavor.
- 1/2 cup vegetable oil: Keeps the cake tender and moist; coconut oil works beautifully too for a hint of tropical flavor.
- 2 large eggs: Bind everything together while contributing to the cake’s rich texture; flax eggs are perfect for a vegan twist.
- 1 cup buttermilk: Adds tang and helps the cake stay soft and fluffy; you can substitute with milk and vinegar.
- 2 tsp vanilla extract: Enhances all the flavors and adds a sweet, fragrant finish.
- 2 1/2 cups all-purpose flour: The structure of the cake; whole wheat flour is a wholesome alternative.
- 1 tbsp baking powder: Helps the cake rise beautifully—make sure it’s fresh!
- 1/2 tsp baking soda: Supports leavening and helps tenderize the crumb.
- 1/2 tsp salt: Just enough to bring out all the sweetness and spice.
- 1 tsp ground cinnamon: For that warm, inviting aroma that makes this cake irresistible.
- 1/2 tsp ground nutmeg: Adds a cozy spice note; allspice can be swapped if needed.
- 1/2 tsp ground ginger: Provides a gentle kick; adjust according to your spice preference.
- 1/2 cup granulated sugar (for cinnamon swirl): The sweet, crunchy layer inside the cake.
- 1 tbsp ground cinnamon (for cinnamon swirl): Essential for the signature honeybun flavor.
- 1 cup powdered sugar (for glaze): Creates a silky finish that tones down the spice gently.
- 2 tbsp milk (for glaze): Helps create a smooth, pourable glaze.

How to Make Irresistibly Moist Sweet Potato Honeybun Cake Recipe
Step 1: Get Your Oven and Pan Ready
Start by preheating your oven to 350°F (175°C) so it reaches the perfect temperature while you prepare your batter. Grease a 9×13-inch baking pan thoroughly to ensure your cake doesn’t stick and comes out with beautiful edges.
Step 2: Mix the Wet Ingredients
In a large mixing bowl, combine your mashed sweet potatoes, granulated sugar, brown sugar, vegetable oil, eggs, buttermilk, and vanilla extract. Use a hand mixer or a sturdy whisk to blend everything until the mixture is smooth and homogenous. This blend ensures your cake has a rich sweetness and incredible moisture throughout.
Step 3: Combine the Dry Ingredients
In a separate bowl, sift the all-purpose flour, baking powder, baking soda, salt, cinnamon, nutmeg, and ginger. Sifting is key here to make sure there are no lumps and the spices distribute evenly, giving every bite a balanced flavor.
Step 4: Bring Wet and Dry Together
Now, gently add the dry ingredients to the wet mixture in batches. Stir with a spatula or wooden spoon just until everything is combined—overmixing can make the cake dense, and we want fluffy and tender!
Step 5: Prepare the Cinnamon Swirl
In a small bowl, stir together the 1/2 cup granulated sugar and 1 tablespoon ground cinnamon. This cinnamon swirl is the magic layer that creates those signature honeybun cake ribbons of sweet, spicy goodness.
Step 6: Layer the Batter and Cinnamon Swirl
Pour half of the batter into your prepared pan, smoothing it evenly. Sprinkle half of your cinnamon sugar mixture on top. This layering step is what creates that delightful swirl and texture contrast inside.
Step 7: Complete the Layering and Create the Swirl Effect
Add the remaining cake batter over the cinnamon layer. Take a knife and gently swirl through the batter to create a beautiful marbled effect. Then, sprinkle the remaining cinnamon sugar on top to finish.
Step 8: Bake to Perfection
Pop the cake into the oven and bake for 35 to 40 minutes. You’ll know it’s done when a toothpick inserted in the center comes out clean or with just a few moist crumbs. This precise baking time is crucial to achieve that irresistibly moist crumb.
Step 9: Let It Cool
Remove the cake from the oven and let it cool completely in the pan on a wire rack for about 30 minutes. Cooling ensures that your glaze will set properly and the cake slices cleanly.
Step 10: The Glaze Finish
Whisk together powdered sugar, milk, and vanilla extract until smooth. Drizzle generously over the cooled cake. The glaze adds a sweet, creamy touch that perfectly balances the cinnamon and spices, making this truly the Irresistibly Moist Sweet Potato Honeybun Cake Recipe you’ve been dreaming of.
How to Serve Irresistibly Moist Sweet Potato Honeybun Cake Recipe

Garnishes
While the glaze looks stunning on its own, consider topping slices with a sprinkle of chopped toasted pecans or a light dusting of additional cinnamon. Whipped cream or a dollop of vanilla ice cream can turn this into an elegant dessert that’s hard to resist.
Side Dishes
This cake is wonderfully versatile. Pair it with a hot cup of chai tea or rich coffee for breakfast or brunch. For an afternoon treat, it complements fruit salads or a cheese plate featuring mild cheddar or cream cheese spreads.
Creative Ways to Present
Present individual slices on rustic wooden platters with fresh mint leaves for a pop of color. Or flip the script and serve this cake warm topped with a drizzle of honey and a side of caramelized banana slices for a unique twist that will wow your guests.
Make Ahead and Storage
Storing Leftovers
You can keep leftover cake wrapped tightly in plastic wrap or stored in an airtight container at room temperature for up to 2 days. For longer freshness, refrigerate for up to 5 days, but warm it slightly before serving to bring back that soft texture.
Freezing
This cake freezes beautifully. Wrap tightly with plastic wrap and then aluminum foil to prevent freezer burn. Freeze for up to 3 months. When you’re ready, thaw overnight in the fridge for the best texture.
Reheating
Reheat slices gently in the microwave for 15-20 seconds or warm in a low oven (about 300°F) for 10 minutes. Adding a tiny brush of melted butter on top before reheating can make it taste freshly baked again!
FAQs
Can I use canned sweet potatoes instead of fresh?
Absolutely! Make sure to drain them well and mash thoroughly. The flavor and moisture content might vary slightly, but the cake will still turn out delicious.
Is there a vegan version of this cake?
Yes, simply replace eggs with flax eggs (mix 1 tablespoon flaxseed meal with 3 tablespoons water per egg and let sit) and use plant-based milk and oil. The cake remains just as moist and flavorful.
Can I substitute the buttermilk?
If you don’t have buttermilk on hand, mix 1 tablespoon of vinegar or lemon juice with milk and let it sit for 5 minutes. This DIY buttermilk substitute works perfectly in this cake.
Why is the cinnamon swirl important?
The cinnamon swirl not only adds a sweet, slightly crunchy texture but also mimics the nostalgic honeybun flavor we all love, turning a simple cake into an extraordinary treat.
Can I make this cake gluten-free?
Yes, using a gluten-free all-purpose flour blend can work well. Just ensure the blend includes xanthan gum or a similar binder for the best texture.
