Ingredients for sweet potato cinnamon roll cake
Sweet potato puree, warm spices, and gooey cinnamon swirls make this cake feel like fall in every bite.
| Ingredient | Amount | Notes |

| Vanilla Extract 🌸 | 2 tsp | Pure extract preferred |
| Baking Powder 🍞 | 2 tsp | Diamond Crystal brand |
| Ground Cinnamon 🌿 | 1 ½ tsp | For cake batter |

The sweet potato puree is non-negotiable here—Libby's unsweetened canned puree is my go-to, but homemade works too. Grab a 29-ounce can from the baking aisle, not the soup section. For the flour, King Arthur or Gold Medal brands give the best texture. The cinnamon-sugar filling is where the magic happens: mix 1 cup sugar with 3 tbsp cinnamon—don't skimp on the cinnamon. I like to toast my cinnamon sticks first for deeper flavor, then grind them in a spice grinder. The cream cheese? Philadelphia brand is foolproof, but any full-fat block works if you let it sit out for 30 minutes before mixing.
No sweet potato puree? Roast 2 lbs sweet potatoes until tender, scoop out the flesh, and blend until smooth. Short on butter? Coconut oil works in a pinch, but it'll taste slightly different. The frosting can be made ahead—just whip it up and store in the fridge for 3 days. Want extra warmth? Add a pinch of nutmeg or cardamom to the frosting. For the cake batter, don't overmix—just combine until just combined. The filling goes on right before baking, so keep it handy. Pro tip: use a spatula to spread the filling evenly—it makes all the difference in those perfect swirls.
This cake keeps beautifully—3 days at room temperature covered loosely, or 1 week refrigerated. The frosting can be stored separately for 2 days in the fridge. To reheat, wrap slices in foil and warm for 15-20 seconds in the microwave. Freezing? Slice first, then wrap individually—2 months is the limit. I always make a double batch because it disappears fast. The leftovers? Perfect for breakfast the next morning—just pop in the toaster.
Why You'll Love This Recipe
- One-Bowl Wonder: I swear by this trick—just mix everything in one bowl. No fancy layers, no fussing with yeast or rolling dough. The sweet potato puree does all the heavy lifting, blending seamlessly with the flour and butter for a cake that’s basically foolproof.
- Cinnamon-Sugar Magic: That first bite? Warm, spiced, and just sweet enough to make you slow down. The butter and sugar caramelize into a sticky, gooey crust while the center stays tender—like a cross between a cinnamon roll and a cake, but better.
- Weeknight or Celebration: Honestly, this works for everything. Serve it warm for breakfast with a drizzle of cream cheese frosting, or slice it cold for a picnic. Even my picky uncle asked for seconds at Thanksgiving—no one cares if it’s "fancy" when it tastes this good.
- Budget-Friendly Stash: Sweet potatoes and eggs stretch further than you’d think. I’ve made this last four days in the fridge, reheated in slices, and still tasted fresh. Plus, the puree keeps for weeks, so you’re not scrambling last-minute—just pull it out and bake.
Step-by-step instructions for sweet potato cinnamon roll cake
Let's bake this dreamy cake with gooey cinnamon swirls and creamy frosting.
👨🍳 Step 1: Mix the Cake Batter
Preheat your oven to 350°F and grease a 9-inch round cake pan or line it with parchment paper. In a large mixing bowl, combine the 1.5 cups sweet potato puree, 1.5 cups granulated sugar, 1 cup softened unsalted butter, and the 2 whole large eggs. Mix until smooth and creamy.
In a separate bowl, whisk together the 2.5 cups all-purpose flour, 2 tsp baking powder, 1.5 tsp ground cinnamon, 0.5 tsp ground nutmeg, and 0.5 tsp salt. Gradually add the dry ingredients to the wet mixture, alternating with 2 tsp vanilla extract, until just combined. Be careful not to overmix—the batter should be thick but pourable. Here's the thing—sweet potato puree makes the batter denser, so resist the urge to add extra liquid.
🥘 Step 2: Prepare the Cinnamon-Sugar Filling
While the batter rests, make the cinnamon-sugar filling. In a small bowl, mix 1 cup granulated sugar with 3 tbsp ground cinnamon (this makes the 1.5 cups cinnamon-sugar filling). Set aside—this is what'll create those gorgeous swirls in your cake.
Here's a pro tip: Use a fine-mesh sieve to dust the cinnamon-sugar mixture over the batter. This ensures even distribution and prevents clumps that can make your cake dense. You'll want to keep this mixture handy because we'll use it to create the signature swirl pattern in the next step.
🍳 Step 3: Layer and Swirl the Cake
Pour about half of the cake batter into your prepared pan. Using the back of a spoon or a spatula, gently spread it evenly to cover the bottom. Now for the fun part—sprinkle about half of the cinnamon-sugar filling over the batter. Use a butter knife to create a spiral pattern, pulling from the center outward.
Add another layer of batter, then sprinkle the remaining cinnamon-sugar filling on top. Use the knife to swirl it through the batter, creating those beautiful cinnamon streaks. Top with the final layer of batter, then gently smooth the surface with the back of a spoon. This layering technique is what gives this cake its signature look and flavor—don't rush it!
🔥 Step 4: Bake to Golden Perfection
Bake the cake for 45-50 minutes, or until a toothpick inserted into the center comes out clean. The edges should be golden brown, and the top should spring back when gently pressed. I know it's tempting to check early, but resist—this cake needs that full baking time to develop its moist texture and rich flavor.
Once baked, let the cake cool in the pan for 15 minutes, then transfer it to a wire rack to cool completely. This resting period is crucial—it allows the cake to set properly and makes slicing much easier. The aroma filling your kitchen as it bakes? That's your reward for waiting.
🍽️ Step 5: Make the Cream Cheese Frosting
While the cake cools, make the frosting. In a medium bowl, beat the 8 oz room-temperature cream cheese until smooth. Gradually add the 3 cups powdered sugar and 0.5 cup cold heavy cream, mixing on low speed until combined. Add the 1 tsp vanilla extract and beat until fluffy and smooth.
Here's the key: Cold heavy cream whips up lighter than room-temperature cream. Spread the frosting over the completely cooled cake, then decorate with extra cinnamon-sugar swirls if you're feeling fancy. This frosting is what ties the whole cake together—creamy, sweet, and perfectly balanced with the spiced cake layers.
Pro Tips For Making Sweet Potato Cinnamon Roll Cake
- STRAIN THAT PUREE: The first time I skipped this, my cake turned out gummy and sad. Sweet potato puree has more water than you’d think—strain it through a fine-mesh sieve or cheesecloth to remove excess moisture. This keeps your batter light and prevents a dense, gluey texture. (Yes, even if you’re tempted to skip it for speed.)
- WHIP THE BUTTER COLD: I used to melt the butter right into the mix, and the cake always ended up dry. Instead, beat the cold, cubed butter into the flour and sugar first—this creates a proper crumb structure. Once the eggs come in, the butter will soften naturally, but starting cold guarantees flakiness. (And don’t overmix—just until it looks like wet sand.)
- DON’T OVERBAKE THE CENTER: Sweet potato cakes are forgiving, but overbaking turns them into brick. Test with a skewer at 325°F (165°C)—it should come out with light crumbs clinging, not a clean stick. The center will firm up as it cools, but if it’s dry at this stage, it’s past saving. (Pro move: Tent with foil 10 minutes before the time’s up to slow the top from browning too fast.)
- SWAP 1 EGG FOR YOGURT: This one’s for when you’re fresh out of eggs or want extra moisture. Replace one large egg with ½ cup plain Greek yogurt—it keeps the cake tender without sacrificing rise. The acidity also balances the sweetness, which is especially helpful if your sweet potato puree is extra starchy. (Works best if you add it after the wet ingredients are mixed.)
Regional styles of this recipe
Southern Comfort Style
In the South, this cake gets an extra layer of warmth with a touch of bourbon or pecan butter in the frosting. I like adding 1 tablespoon bourbon (like Buffalo Trace) to the cream cheese frosting for depth, or swirling in 2 tablespoons pecan butter after baking.
The pecans add a nutty crunch that pairs perfectly with the cinnamon. Serve with a cup of hot sweet tea for the ultimate Southern experience. 🌶️
Midwest Spiced Twist
The Midwest version leans into cardamom and ginger for a cozy, aromatic twist. Add ½ teaspoon ground cardamom and ½ teaspoon ground ginger to the cinnamon-sugar filling for a warm, almost gingerbread-like flavor.
Top with a sprinkle of crushed gingersnaps before baking for extra texture. This variation feels like a hug on a chilly fall day. ❄️
Pacific Northwest Maple Glaze
Out West, they love a maple glaze drizzled over the frosting. Mix ½ cup maple syrup with 1 cup powdered sugar and 1 teaspoon vanilla extract, then thin with 1-2 teaspoons milk until pourable.
Drizzle over the cooled cake for a sticky, sweet finish that complements the cinnamon without overpowering it. Pair with a chai latte for the perfect cozy dessert. 🍁
New England Pumpkin Swirl
For a seasonal twist, replace half of the sweet potato puree with ½ cup pumpkin puree and add 1 teaspoon pumpkin pie spice to the cake batter. The filling stays the same, but the cake gains a subtle pumpkin depth.
Top with whipped cream and a sprinkle of pumpkin seeds for a festive touch. This version is a crowd-pleaser during harvest season. 🎃
Gluten-Free Adaptation
In regions with dietary restrictions, swap the all-purpose flour for a 1:1 gluten-free baking blend like King Arthur Measure for Measure. Add ½ teaspoon xanthan gum to the dry ingredients to improve texture.
The cake will still be moist, but slightly denser—perfect for those who want to enjoy the flavors without compromise. 🌾
Vegan Version
For plant-based bakers, use vegan butter (like Miyoko's) and flax eggs (replace eggs with 2 tablespoons ground flaxseed + 6 tablespoons water). The frosting becomes dairy-free with vegan cream cheese (such as Kite Hill) and coconut cream instead of heavy cream.
The texture stays rich and creamy, with no one guessing it's vegan. 🌱

Frequently asked questions
Can I make this cake without sweet potato puree?
You can substitute with 1 cup unsweetened applesauce or ½ cup pumpkin puree to maintain moisture, but the flavor will differ slightly. The sweet potato adds natural sweetness and a velvety texture that's hard to replicate. If you're avoiding carbs, try ½ cup mashed avocado—it keeps the cake tender while adding healthy fats.
How do I prevent the cinnamon-sugar filling from sinking to the bottom?
Use a fine-mesh sieve to dust the cinnamon-sugar evenly over the batter layers. This creates a light, airy distribution that stays put during baking. Also, don't overmix the batter—keep it thick but pourable. For extra insurance, chill the cake in the fridge for 15 minutes before baking to help the layers set.
Can I bake this cake in a different pan shape?
Yes! For a 9x13-inch pan, reduce baking time to 35-40 minutes. For a 6-inch round pan, bake for 40-45 minutes. Adjust the batter quantity proportionally—this cake works best with a height of 1.5-2 inches. Line the pan with parchment paper for easy removal.
Why did my cake turn out dense instead of light?
Overmixing the batter is the most common culprit—stop mixing once the dry ingredients are just combined. Another reason could be too much flour or not enough butter. For extra moisture, add 1 tablespoon sour cream or Greek yogurt to the batter. Also, ensure your sweet potato puree isn't watery—drain canned puree if needed.
How can I make this cake ahead of time?
Bake the cake up to 2 days ahead and store it at room temperature, covered loosely with plastic wrap. For longer storage, refrigerate for up to 5 days or freeze for 3 months. Frost the cake just before serving to keep it looking fresh. The flavors actually improve overnight!
