Sweet Potato Pound Cake Recipe From Scratch, Moist & Spiced

Sweet potato pound cake is a rich, buttery cake made with mashed sweet potato, warm spices, and a tender, close crumb. A little brown sugar deepens its flavor, while the sweet potato adds moisture; serve it plain or finish it with a simple vanilla glaze.

Ingredients

1 cup (250 g) cooked, mashed sweet potato, cooled and smooth
1 cup (227 g) unsalted butter, softened
1¾ cups (350 g) granulated sugar
¼ cup (50 g) packed light brown sugar
4 large eggs, at room temperature (about 200 g without shells)
2 teaspoons (10 ml) vanilla extract
3 cups (375 g) all-purpose flour, preferably weighed
1 teaspoon (4 g) baking powder
½ teaspoon (3 g) fine salt
1 teaspoon ground cinnamon
½ teaspoon ground nutmeg
¼ teaspoon ground ginger
½ cup (120 ml) whole milk, at room temperature
For the optional glaze: 1 cup (120 g) powdered sugar, 1½ tablespoons (22 ml) milk, and ¼ teaspoon vanilla extract
Softened butter and 1 tablespoon (8 g) flour for preparing the pan, or baking spray with flour

Instructions

Prepare the pan and oven. Set a rack in the lower-middle of the oven and heat it to 350°F (175°C). Thoroughly grease and flour a 10-inch tube pan or 12-cup Bundt pan, getting into every groove. Tap out excess flour. If using baking spray, coat the pan evenly just before adding the batter. This is a substantial cake, so avoid a smaller pan that could overflow.
Check the sweet potato. The puree should be fully cooked, cooled, and thick rather than watery. Mash it until there are no firm lumps; if it looks wet, blot or drain it briefly. Measure 1 cup (250 g) after mashing. Homemade puree can be prepared ahead by roasting or steaming a sweet potato until tender, then cooling and mashing it. Do not use sweet potato pie filling, which is already sweetened and spiced.
Combine the dry ingredients. In a medium bowl, whisk the flour, baking powder, salt, cinnamon, nutmeg, and ginger until the spices are evenly distributed. Breaking up any flour or spice clumps now helps prevent streaks in the finished cake. Set the bowl aside.
Cream the butter and sugars. In a large bowl, beat the softened butter, granulated sugar, and brown sugar with a hand mixer or stand mixer fitted with the paddle. Beat on medium speed for about 3–4 minutes, stopping to scrape the bowl once or twice. The mixture should look paler and fluffy, not greasy or melted. This step incorporates air that helps the dense batter rise.
Add the eggs and flavoring. Beat in the eggs one at a time, mixing just until each is incorporated before adding the next. Scrape the bowl, then mix in the vanilla and mashed sweet potato. The mixture may look slightly curdled at this point, especially if the ingredients are cool; it will come together when the flour is added. If the butter is very soft or the puree is warm, the batter can turn oily, so use room-temperature rather than hot ingredients.
Finish the batter. Add about one-third of the flour mixture and mix on low speed until only a few dry streaks remain. Mix in half the milk, then repeat with another third of the flour, the remaining milk, and the final flour. Scrape the bottom and sides of the bowl, then fold gently until no dry pockets remain. Avoid beating once the flour is in; overmixing can make the cake tough and create a peaked, dense texture.
Fill the pan and bake. Spoon the batter evenly into the prepared pan and smooth the top. Bake for 70–80 minutes, rotating the pan once after about 45 minutes if your oven browns unevenly. Begin checking at 70 minutes. A long wooden skewer inserted near the center should come out clean or with a few moist crumbs, not wet batter. Because this batter contains eggs, check with an instant-read thermometer that the center reaches at least 160°F (71°C), the USDA FSIS safe minimum for egg dishes; pound cake is typically fully baked at a higher center temperature, around 200–205°F (93–96°C). If the top is getting dark before the center is done, loosely tent it with foil.
Cool before turning out. Set the pan on a cooling rack for 15 minutes. Run a thin, flexible knife around the exposed edges if needed, then invert the cake onto the rack and lift off the pan carefully. Let the cake cool completely, about 90 minutes, before glazing or slicing. A warm cake can crumble when cut, and glaze poured over it may melt away.
Make and add the optional glaze. Whisk the powdered sugar, 1½ tablespoons milk, and vanilla in a small bowl. Add a few drops more milk for a thinner drizzle or a spoonful of powdered sugar if it is too loose. Drizzle over the cooled cake and let the glaze set for about 10 minutes before serving. For a plain cake, skip the glaze and serve the slices as they are.

Tips

Use thick puree, not watery mash. Roasting usually produces a drier, more concentrated sweet potato than boiling. If boiling is your method, drain the potato well and let it steam dry before mashing. Excess water can weigh down the crumb and extend baking time.
Bring the ingredients to room temperature. Soft butter should give slightly when pressed but should not look shiny or melted. Room-temperature eggs and milk blend more smoothly into the creamed butter, reducing the chance of a separated batter. If you forgot the eggs, place them in warm—not hot—water for several minutes.
Measure flour carefully. Weighing gives the most reliable result. If using cups, fluff the flour, spoon it into the measuring cup, and level the top instead of scooping directly from the bag. Too much flour can make this already substantial cake dry.
Grease every detail of a Bundt pan. Pay special attention to the center tube and any narrow grooves. Letting the cake rest for 15 minutes before turning it out helps it release, but leaving it in the pan much longer can make steam soften the crust and encourage sticking.

Serving Suggestions

Serve the cake in modest slices at room temperature, when its buttery texture and sweet potato flavor are easiest to appreciate. The vanilla glaze is pleasant but not essential: a light dusting of powdered sugar also gives the slices a finished look without making the cake much sweeter. For a simple dessert plate, add whipped cream or a spoonful of lightly sweetened yogurt and a few toasted pecans.

This cake works well alongside coffee or black tea for an afternoon treat, and it can be part of a holiday dessert table with fruit, custard, or a less-sweet dessert for contrast. If serving it after a large meal, cut thinner slices; the rich crumb is satisfying without a large portion. For a brunch spread, serve it plain so it does not compete with other sweet dishes. Glazed slices are best served after the icing has set, so the topping stays neat on the plate.

Variations

Make it citrusy: Add 1 tablespoon finely grated orange zest to the butter and sugars, and use orange juice in place of 1 teaspoon of the glaze milk. The citrus brightens the warm spices without changing the basic cake method.

Add nuts: Fold in ¾ cup (85 g) chopped toasted pecans or walnuts with the final flour addition. Toasting first brings out their flavor; cool them completely so they do not soften the butter in the batter. Keep the pieces small enough to distribute evenly.

Adjust the spices: Use 1½ teaspoons cinnamon and omit the ginger for a gentler, familiar flavor, or add a pinch of cloves for a more pronounced spice profile. Ground spices vary in strength, so keep additions restrained if they have been open for a long time.

Use a different milk: Unsweetened oat milk can replace the whole milk in equal quantity, although the cake may taste slightly less rich. Avoid sweetened or flavored milk because it can make the batter sweeter and alter the vanilla-spice balance. A dairy-free butter substitute may work, but choose a firm baking stick rather than a soft tub spread; the texture and browning may differ.

Storage and Reheating

Let the cake cool completely before storing it so trapped steam does not make the crust damp. Keep it covered at room temperature for up to 2 days if your kitchen is cool and the cake is unglazed. For longer storage, refrigerate it in an airtight container for 3–4 days; refrigerate within 2 hours of baking or serving. A glaze can become sticky in a sealed container, so allow it to set first and place a sheet of parchment loosely over the top if needed.

To freeze, wrap the whole unglazed cake or individual slices tightly in plastic wrap and then foil, or use a freezer-safe container. Freeze for up to 2 months for the best flavor and texture. Thaw wrapped slices in the refrigerator overnight or at room temperature for about 1–2 hours, then add glaze if desired. For a gently warmed slice, microwave it for about 10–15 seconds; avoid heating for too long, which can make the crumb rubbery. If reheating a portion as a leftover, heat it to 165°F (74°C) in accordance with USDA FSIS guidance.

Frequently Asked Questions

Can I use canned sweet potato? Yes, provided it is plain cooked sweet potato rather than pie filling. Drain it if there is liquid, mash it smooth, and weigh or measure 1 cup (250 g). Canned puree can be softer or wetter than roasted homemade puree, so drain excess moisture before adding it to the batter.

How do I cook sweet potatoes for the puree? Roast a whole sweet potato at 400°F (200°C) until completely tender, usually 45–60 minutes depending on its size. Cool it, remove the skin, and mash the flesh. Steaming is another option; boiling works too, but drain the pieces thoroughly and let excess moisture evaporate before mashing.

Why did my cake stick to the pan? The most common causes are missed spots when greasing, flour that was not distributed into the pan’s grooves, or turning the cake out too soon or too late. Coat the pan carefully, use flour or baking spray made for baking, and wait 15 minutes before inverting. If a section sticks, place the pan back over the warm cake for a few minutes to loosen it gently.

Can I bake this in a loaf pan? The full recipe makes more batter than one standard loaf pan can safely hold. Divide it between two greased 9-by-5-inch loaf pans and fill each no more than about two-thirds full. Start checking around 50 minutes, but expect the actual time to vary with the pans and oven; use the skewer and temperature checks rather than relying on the clock alone.

Can I make the cake ahead? Yes. Bake and cool it a day ahead, then cover it tightly and keep it at room temperature if unglazed, or refrigerate it if needed. Add the glaze closer to serving for the cleanest finish. You can also freeze the cooled, unglazed cake and thaw it before serving.

How can I tell if the cake is done without drying it out? Start checking at 70 minutes. The skewer should come out clean or with a few moist crumbs, and the center should be set rather than wobbling. A thermometer gives another useful check: the cake must reach 160°F (71°C) for egg safety, but its texture is generally fully baked when the center is closer to 200–205°F (93–96°C). Remove it once those cues agree rather than baking extra time just in case.
