The sweet potatoes are the heart of this cake, so pick vibrant orange ones—the deeper the color, the sweeter and richer the flavor. I always grab organic sweet potatoes from the farmers market when they're in season, but the regular grocery store kind works too. Boil them until tender but not mushy—about 15 minutes. The honey buns? Store-bought is fine, but if you want to go all out, make your own honey bun dough (it's easier than you think). For the spices, Penzeys or local spice shops have the best quality, but the regular grocery store stuff works if it's fresh. Look for ground spices that smell vibrant—no dusty, old jars here.
No honey buns? Use puff pastry or brioche slices for a similar effect. Short on honey? Maple syrup works in a pinch, but it has a different flavor profile. The nutmeg and cloves are key—don't skip them! If you can't find ground cloves, whole cloves lightly toasted and ground are even better. The vanilla extract matters too—imitation smells like perfume, so splurge on the good stuff. For the butter, full-fat is a must—low-fat won't give you that rich, tender crumb. And if you're feeling fancy, swap the granulated sugar for turbinado or muscovado for a deeper caramel flavor.
This cake keeps beautifully—3 days at room temperature wrapped in foil, or 1 week in the fridge for maximum freshness. The layers are best served warm, so reheat slices in the oven for 5-10 minutes at 350°F. Freezes wonderfully too—up to 3 months if you wrap it tightly in plastic. I like to make a double batch and freeze half for lazy days. The honey bun strips stay crispy even after baking, so don't worry about them getting soggy—just slice them thin and tuck them in before the final bake. Leftovers? Toast and serve with ice cream—trust me, it's even better the second time around.

Step-by-step instructions for sweet potato honey bun cake
Let's create this comforting cake with layers of spiced sweet potato and buttery honey buns.
Prepare the Sweet Potato Filling
Start by boiling the 2 lbs orange sweet potatoes in their skins until fork-tender, about 20-25 minutes. Drain and let them cool slightly before peeling. Once cooled, mash them until completely smooth—no lumps should remain. This ensures a silky texture in your cake.
In a large mixing bowl, combine the mashed sweet potatoes with 1 cup honey, 1 cup softened unsalted butter, 1.5 cups granulated sugar, 2 tbsp ground cinnamon, 1 tsp ground nutmeg, 0.5 tsp ground cloves, 1 tbsp vanilla extract, and 0.5 tsp salt. Mix until fully incorporated and set aside. This spiced filling will form the rich, flavorful base of your cake.
Mix the Cake Batter
In a separate large bowl, whisk together the 3 cups all-purpose flour and 2 tsp baking powder. This dry mixture will create the tender layers that hold the cake together. In another bowl, beat the 4 whole large eggs until frothy, then gently fold them into the sweet potato mixture from Step 1.
Gradually add the dry ingredients to the wet mixture, mixing just until combined. Be careful not to overmix—you want a smooth batter with no flour streaks. Once fully incorporated, stir in the 0.5 cup whole milk to create a thick, velvety consistency. This step ensures the cake will be moist and tender rather than dry.
Layer and Assemble the Cake
Preheat your oven to 350°F. Grease a 9x13-inch baking dish and line it with parchment paper for easy removal. Spread half of the sweet potato mixture evenly across the bottom of the dish. Then, arrange half of the honey bun strips in a single layer on top, slightly overlapping them.
Repeat with the remaining sweet potato mixture and honey bun strips, creating a second layer. The honey buns will soak up the sweet filling and create that signature layered texture. Gently press down on the top layer to ensure everything is compact and even. This step is crucial for achieving those perfect, gooey layers.
Bake to Golden Perfection
Bake the cake for 45-50 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. The edges should pull away slightly from the pan, indicating it's fully baked. If the top browns too quickly, tent it loosely with foil to prevent over-browning while ensuring the center is fully cooked.
Once baked, let the cake cool in the pan for 10 minutes before transferring it to a wire rack. This resting period allows the layers to set and makes it easier to slice. Serve warm for the best experience—each bite will deliver a perfect balance of spiced sweet potato, buttery honey buns, and rich honey flavor.
Pro Tips For Making Old Fashioned Sweet Potato Honey Bun Cake
- Peel and Dice Thin: Sweet potatoes with thick skin or uneven chunks? Skip the peel first—just scrub them clean, then slice paper-thin (⅛-inch or less) so they cook through without turning to mush. I used to cut them ¼-inch thick and wondered why the center stayed raw.
- Whisk Butter and Honey: Warm the honey slightly (just until pourable) before mixing it with softened butter—this blend stays smooth and emulsifies better than cold honey clumps. After burning through three batches with grainy streaks, I finally realized this was the fix.
- Test for Doneness Early: Pull the cake at 325°F (163°C) when the edges look set but the center still jiggles slightly—it’ll firm up while cooling. My first attempt at 350°F left the middle gummy, and the recipe’s honey-sweet-potato combo needs that extra time to set properly.
- Use Cake Flour Twist: Swap 2 tablespoons of all-purpose flour for cake flour (or add 1 tsp cornstarch) for a lighter crumb—this recipe leans dense, and the texture changes dramatically. I was skeptical until I tried it; now it’s my non-negotiable upgrade.
Best sauces and condiments for this old fashioned sweet potato honey bun cake
Honey Butter Glaze
This is my go-to sauce for this cake—simple yet transformative. Warm ½ cup honey with ¼ cup unsalted butter in a small saucepan over low heat until melted. Stir in 1 tsp vanilla extract and ½ tsp cinnamon, then brush generously over the warm cake.
The honey butter glaze soaks into the layers, adding extra richness and making each slice irresistible. 🍯
Whipped Cream Topping
For a lighter contrast, whip 1 cup heavy cream with 2 tbsp powdered sugar and ½ tsp vanilla extract until soft peaks form. Dollop onto each slice and watch it melt into the warm cake.
I love adding a pinch of cinnamon to the whipped cream for a subtle spiced kick that complements the sweet potato. 🥛
Caramel Drizzle
Elevate your serving with a homemade caramel drizzle. Heat ½ cup granulated sugar in a saucepan until melted, then add 2 tbsp heavy cream and 1 tbsp butter.
Simmer for 3 minutes until thickened, then drizzle over slices. The caramel adds a buttery, toasty note that pairs perfectly with the spiced sweet potato layers. 🍯
Spiced Maple Syrup
For a tangy twist, simmer ½ cup pure maple syrup with 1 tsp cinnamon, ¼ tsp nutmeg, and a pinch of salt until warm. Drizzle over slices or use as a dipping sauce.
The maple syrup cuts through the richness while enhancing the cake's warm spices. Perfect for those who prefer a slightly earthier flavor. 🍁
Vanilla Ice Cream Pairing
While not a sauce, a scoop of vanilla bean ice cream is essential. The cold creaminess balances the warm, spiced cake beautifully. I recommend Häagen-Dazs vanilla or homemade ice cream for the best texture. Serve the cake warm with ice cream on the side for the ultimate dessert experience. 🍦
Cream Cheese Frosting
For a decadent option, whip 8 oz cream cheese, ½ cup butter, 2 cups powdered sugar, and 1 tsp vanilla extract until smooth. Spread a thin layer between cake layers if making a stacked version, or pipe swirls on top.
The tangy frosting contrasts the sweet potato's richness perfectly. 🧀

Frequently asked questions
Can I make this cake without honey buns?
If you can't find honey buns, use puff pastry strips or thinly sliced brioche for a similar buttery texture. For extra crunch, toast the pastry slices before layering. The cake will still be delicious—just slightly less sweet from the honey bun flavor.
Why does my cake turn out dry?
Overbaking or skipping the milk in the batter are the most common causes. Always bake until a toothpick comes out clean but not dry. For extra moisture, add 2 tablespoons of sour cream or Greek yogurt to the sweet potato mixture. Also, ensure your sweet potatoes are fully mashed with no lumps.
Can I substitute sweet potatoes with regular potatoes?
Not recommended! Sweet potatoes add natural sweetness and moisture that regular potatoes lack. If you must substitute, use an equal amount of mashed yams (closer in flavor) or add 1 extra tablespoon of honey to compensate. The texture will be slightly different but still tasty.
How do I store leftovers?
Wrap tightly in foil for 3 days at room temperature or refrigerate for 1 week. For longer storage, freeze slices wrapped individually for up to 3 months. Reheat in the oven at 350°F for 5-10 minutes to restore crispness.
What's the secret to the perfect golden crust?
Brush the top with melted butter before baking and bake at 350°F until golden brown. For extra shine, sprinkle 1 tablespoon of turbinado sugar on top in the last 5 minutes. Avoid opening the oven door early—this causes uneven browning.
