Sweet Potato Cake Recipe with Cream Cheese Icing: Moist Crumb and Tangy-Sweet Frosting

This sweet potato cake recipe delivers a moist, spiced crumb that's perfectly balanced with tangy-sweet cream cheese icing—every slice tastes like autumn in dessert form. The secret lies in using roasted sweet potato purée instead of canned, which creates a naturally sweet, velvety texture without added sugar.

I developed this recipe after years of baking sweet potato desserts, and the cream cheese frosting transforms it from simple to showstopping.

The cake itself is foolproof—just mix, pour, and bake at 350°F for 45 minutes—while the frosting requires only 5 minutes of active time but delivers restaurant-quality flavor.

The warm spices (cinnamon, nutmeg) complement the sweet potato beautifully, and the cream cheese icing adds a tangy contrast that keeps every bite interesting. This dessert is rich enough for celebrations but simple enough for a weeknight treat.

What you'll end up with is a golden, domed cake with a tender crumb and frosting so smooth it looks professionally decorated. The sweet potato base gives it natural moisture, while the cream cheese frosting adds that perfect balance of sweet and tangy.

It's the kind of dessert that disappears quickly—guaranteed to impress even picky eaters.

Perfect for fall gatherings, holiday menus, or when you want something special without the fuss. The recipe scales easily, so you can make it for a crowd or just a few slices. Let's get baking!

Ingredients for sweet potato cake recipe with cream cheese icing

Sweet potato purée, warm spices, and creamy frosting—just 15 ingredients for a showstopping dessert.

The sweet potato purée is non-negotiable—roast your own (425°F for 45 minutes) for the best flavor. Skip the canned stuff; it's watery and lacks depth. Trader Joe's sells organic sweet potatoes that work perfectly, but any orange-fleshed variety does the trick. For the spices, Penzeys has true cinnamon and nutmeg if you're willing to splurge, but the regular grocery store stuff works fine if it's fresh. The cream cheese should be full-fat and room temperature—no low-fat shortcuts here. That's where the richness comes from.

No sweet potato? Roasted butternut squash purée works in a pinch (adjust sugar to taste). Running low on vanilla? Vanilla bean paste at half the amount gives you those little specks. The frosting can be made ahead—just whip it up when ready to decorate. For a tangier frosting, add 1 tbsp lemon zest. The cake itself is foolproof, but if you're nervous, line the pan with parchment paper for easy removal. And trust me on the cold butter—it's worth the extra minute to cube it before mixing.

The cake keeps well for 3 days wrapped at room temperature, but the frosting is best used within 2 days. If making ahead, bake the cake, cool completely, then wrap tightly. The frosting can be made 1 day ahead and stored in the fridge—just rewhip before using. For serving, I like to dust with a light powdered sugar sift right before cutting. Leftovers? They disappear fast, but any remaining slices reheat beautifully in the microwave for 10 seconds

Step-by-step instructions for sweet potato cake with cream cheese icing

Here's how to create a perfectly moist sweet potato cake with that signature tangy-sweet cream cheese frosting.

In a stand mixer fitted with the paddle attachment, beat the 0.75 cup unsalted butter and 1.5 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy. You'll see the mixture nearly double in volume and turn pale—this is crucial for that tender crumb. I always use cold cubed butter for this step because it creates tiny air pockets that keep the cake moist.

Here's the thing—don't rush this part. The butter needs to fully incorporate with the sugar to create that perfect texture. If it looks grainy or hasn't lightened much after 3 minutes, give it another minute. The goal is that ribbon stage where the mixture holds soft peaks when the paddle is lifted.

Add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 1.5 cups roasted sweet potato purée and 1 tbsp vanilla extract. The purée should be smooth with no lumps—if you notice any, strain it through a fine-mesh sieve before adding.

This is where the cake gets its signature moisture and subtle sweetness. The sweet potato purée acts as both a natural sweetener and a tenderizer. Mix just until combined—overmixing develops gluten and can make the cake dense. The batter should be thick but pourable, with a beautiful golden hue from the sweet potatoes.

In a separate bowl, whisk together the 2 cups all-purpose flour, 2 tsp baking soda, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, 0.25 tsp ground cloves, and 0.5 tsp salt. Sift the dry ingredients directly into the wet mixture and gently fold together using a spatula.

I always sift the flour first to prevent lumps and ensure even distribution of the spices. The key here is to mix just until the flour disappears—about 15-20 strokes with the spatula. Overmixing develops gluten, which can make the cake tough. The batter should be thick and slightly sticky, with no flour streaks remaining.

Pour the batter into two 9-inch round cake pans lined with parchment paper. Bake in a preheated 350°F oven for 25-30 minutes, or until a toothpick inserted in the center comes out clean and the top springs back when gently pressed. I like to rotate the pans halfway through baking for even browning.

Don't open the oven during the first 20 minutes—this prevents the cakes from sinking. You'll know they're done when the edges are golden brown and the top has pulled away slightly from the pan. The cakes should be moist but not wet, with a beautiful domed shape. Let them cool in the pans for 10 minutes before transferring to a wire rack to cool completely.

In a large bowl, beat the 8 oz cream cheese and 0.5 cup heavy cream on medium speed until smooth and creamy. Gradually add the 3 cups powdered sugar and 1 tbsp lemon juice, mixing on low speed until fully incorporated. The icing should be thick but spreadable—if it's too stiff, add 1-2 teaspoons of milk to loosen it.

This is the moment that matters: the lemon juice brightens the sweetness and balances the richness of the cream cheese. Beat until completely smooth—any lumps will make the finished icing look unprofessional. The icing should be pale yellow with a glossy finish, ready to spread between layers and on top of your cooled cake.

Best sauces and condiments for these flavors

Classic Caramel Sauce

Drizzle a warm homemade caramel sauce over each slice for a luxurious finish. Simmer 1 cup granulated sugar with ¼ cup heavy cream and 2 tbsp unsalted butter until golden amber (about 10 minutes).

Cool slightly, then drizzle over the cake. The caramel's deep sweetness contrasts beautifully with the tangy frosting. 🍯

Spiced Maple Glaze

For a fall-inspired twist, make a quick spiced maple glaze by simmering ½ cup pure maple syrup with 1 tsp ground cinnamon and ¼ tsp ground ginger for 3 minutes.

Brush over the cake layers before adding frosting. The warm spices echo the cake's flavors while adding a glossy sheen. I like to let it set for 15 minutes before frosting.

Salted Caramel Drizzle

Elevate your cake with a salted caramel drizzle—simmer ½ cup brown sugar and ¼ cup heavy cream until bubbly, then stir in 1 tbsp unsalted butter and ¼ tsp flaky sea salt.

Cool slightly and drizzle over the frosting. The salt enhances the sweetness, creating a sophisticated balance. Use a squeeze bottle for clean, professional-looking lines.

Citrus Curd Swirl

Add a bright citrus note by swirling lemon or orange curd between cake layers. Mix ½ cup lemon juice, ½ cup sugar, 2 egg yolks, and ¼ cup butter in a saucepan, cooking until thickened.

Let cool, then pipe swirls onto the cake base before adding frosting. The acidity cuts through the richness, making every bite refreshing.

Chocolate Ganache Drip

For chocolate lovers, melt ½ cup dark chocolate chips with ¼ cup heavy cream until smooth, then drizzle over the cake. Let it set for 10 minutes before adding frosting.

The ganache adds a decadent layer that pairs perfectly with the sweet potato's natural sweetness. Use 70% dark chocolate for a balanced bitterness.
