Sweet Potato Cake

The first bite of sweet potato cake has a way of stopping you in your tracks. Soft, moist, and full of gentle spice, it’s the sort of cake that feels like it was meant to be shared around a table.

The mashed sweet potatoes give it a natural sweetness and that tender, melt-in-your-mouth texture that you don’t forget easily.

It’s the kind of cake that feels homemade in the truest sense—warm, simple, and deeply satisfying.

What makes this cake special is how it balances flavor and texture so naturally.

The earthy sweetness of the sweet potatoes, paired with cinnamon, nutmeg, and ginger, creates layers of taste that unfold slowly as you eat.

It doesn’t need heavy frosting to impress; just a soft dollop of cream on top is enough to make it shine.

This is a recipe that feels familiar, like something passed across generations, yet it has a freshness that makes it just as enjoyable today.

It’s a cake worth baking not because it’s quick or trendy, but because it fills the kitchen with a rich aroma and delivers a slice that feels honest and satisfying every single time.

Sweet Potato Cake Recipe

Ingredients

1 ½ cups mashed sweet potatoes (cooked and cooled)
1 ½ cups all-purpose flour
1 teaspoon baking powder
1 teaspoon baking soda
½ teaspoon salt
1 teaspoon ground cinnamon
½ teaspoon ground nutmeg
½ teaspoon ground ginger
¾ cup granulated sugar
½ cup brown sugar, packed
½ cup vegetable oil
2 large eggs, room temperature
1 teaspoon vanilla extract
½ cup milk

Instructions

Preheat your oven to 350°F (175°C). Grease and flour an 8-inch round or square cake pan, or line it with parchment paper for easy removal.
In a medium bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, nutmeg, and ginger. Set aside.
In a large bowl, combine the mashed sweet potatoes, granulated sugar, brown sugar, and oil. Whisk until smooth and creamy.
Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
Gradually add the dry ingredients to the wet mixture in three parts, alternating with milk. Begin and end with the dry ingredients, mixing gently until just combined. Do not overmix.
Pour the batter into the prepared pan and spread it evenly. Tap the pan lightly on the counter to release any air bubbles.
Bake for 35–40 minutes, or until a toothpick inserted into the center comes out clean.
Remove from the oven and let it cool in the pan for about 10 minutes, then transfer to a wire rack to cool completely.
Serve plain, dusted with powdered sugar, or topped with a generous swirl of whipped cream for a delightful finish.

What Makes Sweet Potato Cake So Moist?

The secret to the incredible moisture in sweet potato cake is the natural starch and sweetness of the mashed sweet potatoes. When blended into the batter, they lock in moisture and create a tender crumb that stays soft for days.

Unlike many cakes that rely only on oil or butter, this recipe uses sweet potatoes as a natural moisture booster, which gives the cake its velvety, melt-in-the-mouth feel.

Can I Use Canned Sweet Potatoes Or Fresh Ones?

You can bake this cake using either, but the choice changes the flavor slightly.

Fresh sweet potatoes: These give the richest taste and allow you to control the texture since you mash them yourself. Baking or boiling them until soft makes them ideal for the cake.
Canned sweet potatoes: These are convenient and work well too, but always choose unsweetened canned sweet potatoes. If they come packed in syrup, they will make the cake overly sweet.

What Type Of Frosting Pairs Well With Sweet Potato Cake?

Sweet potato cake is already flavorful, so it doesn’t require heavy toppings. A light finish works best.

Whipped cream: Soft and airy, it balances the natural richness of the cake.
Cream cheese frosting: Adds a tangy touch that complements the sweetness beautifully.
Powdered sugar dusting: Perfect if you prefer to keep it extra simple but still attractive.

How Can I Make Sweet Potato Cake More Flavorful?

If you want to deepen the taste, small tweaks can make a big difference.

Add orange zest: A hint of citrus brightens the earthy flavor of sweet potatoes.
Mix in nuts: Chopped pecans or walnuts bring crunch and warmth.
Sprinkle shredded coconut: It adds a delicate sweetness and texture.
Use extra spice: Boosting cinnamon, ginger, or nutmeg creates a more aromatic cake.

Can Sweet Potato Cake Be Made Ahead Of Time?

Yes, this cake is an excellent make-ahead dessert. The flavors actually improve as it rests, making it even more delicious the next day.

Bake the cake, let it cool completely, and then cover tightly with plastic wrap or store in an airtight container.

If you plan to serve with whipped cream or frosting, add it just before serving to keep the topping fresh.

How Do I Store Sweet Potato Cake Properly?

Storing the cake correctly keeps it moist and tasty for days.

Room temperature: Store in an airtight container for up to 2 days. Keep it in a cool spot, away from direct sunlight.
Refrigerator: If frosted or topped with cream, place in the fridge. It will stay fresh for 4 to 5 days. Let it sit at room temperature for 15 minutes before serving, so it’s soft again.
Freezer: Wrap unfrosted slices individually in plastic wrap, then place in a freezer bag. It freezes well for up to 2 months. Thaw overnight in the refrigerator and bring to room temperature before serving.

Can I Make Sweet Potato Cake Gluten-Free?

Yes, you can swap the all-purpose flour for a gluten-free flour blend that’s made for baking.

Choose a blend that already contains xanthan gum for structure. The flavor will stay the same, but the texture might be slightly denser depending on the blend used.

Is Sweet Potato Cake Healthy Compared To Regular Cake?

Sweet potato cake is not a health food, but it does have some advantages compared to traditional cakes. Sweet potatoes provide natural sweetness, fiber, and nutrients like vitamin A and potassium.

Using them in a dessert means you’re adding more than just empty calories. Of course, sugar and oil are still part of the recipe, so it’s best enjoyed as a balanced treat rather than an everyday snack.

What Can I Serve With Sweet Potato Cake?

Sweet potato cake stands beautifully on its own, but pairing it with other foods can make it even more satisfying.

Fresh fruits: Strawberries, blueberries, or sliced pears add a refreshing touch.
Warm drinks: A cup of tea, hot chocolate, or spiced coffee makes it feel extra cozy.
Ice cream: Vanilla or caramel-flavored ice cream works wonderfully for a more indulgent dessert.
