Ingredients for betty crocker sweet potato cake
Sweet potatoes, spices, and a velvety vanilla swirl—this cake delivers that signature Betty Crocker moistness.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Sweet Potatoes 🍠 | 1 ½ cups | Drained, mashed smooth |
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Vegetable Oil 🫒 | 1 cup | Light or canola preferred |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🌸 | 2 tsp | Pure, not imitation |
| Baking Soda 🧪 | 1 tsp | Pure, not baking powder |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated if possible |
| Ground Ginger 🌶️ | 1 tsp | Freshly ground for warmth |
| Salt 🧂 | 1 tsp | Fine sea salt preferred |
| Vanilla Pudding Mix 🍮 | 1 box | Instant, 3.4 oz size |
| Milk 🥛 | ½ cup | Whole for creaminess |
| Sour Cream 🥛 | ½ cup | Full-fat for best texture |
The sweet potatoes are the secret weapon here. Grab the canned, drained kind—it’s pre-cooked and saves time. Libby’s or Great Value brands work perfectly, but if you’re feeling fancy, grab fresh sweet potatoes and roast them first. For the spices, Penzeys or bulk bins give the freshest grind—nutmeg and ginger lose flavor fast once opened. The vanilla extract? Nothing but pure—imitation just won’t cut it. I always double-check the label to avoid that artificial aftertaste. And for the pudding mix, Betty Crocker’s vanilla is the classic choice, but any instant vanilla will do in a pinch.
No vanilla pudding mix? Make your own swirl with 2 tbsp powdered sugar, 1 tbsp cornstarch, and 1/4 tsp salt mixed with 1/4 cup milk and 1/2 cup sour cream. Short on sweet potatoes? Substitute 1.5 cups mashed regular potatoes—it’ll still work, though the flavor won’t be quite the same. For the oil, vegetable or canola keeps it light, but melted butter adds richness if you prefer. And if you’re watching sugar, reduce it by 1/4 cup—just know the cake might be slightly denser. The spices? Don’t skip the nutmeg—it’s what gives that warm, cozy vibe.
This cake keeps beautifully—wrapped in plastic at room temp for 2 days or fridge for 5 days. For leftovers, slice and reheat in the microwave for 15 seconds. Freezes like a dream too—wrap tightly and it’ll stay moist for up to 3 months. I always bake two cakes when I make this—one for now, one for later. The vanilla swirl sets perfectly, but if you’re worried, chill the cake for 10 minutes before slicing. Trust me, it’s worth the wait.

Step-by-step instructions for Betty Crocker sweet potato cake
This spice cake delivers that perfect moist crumb with a warm vanilla swirl—here's exactly how to nail it every time.
👨🍳 Step 1: Prep the Sweet Potato Base
Drain the 1.5 cups canned sweet potatoes thoroughly and mash them completely smooth using a potato masher or fork. You want a texture with no lumps—this ensures your cake will be tender, not dense. I like to press the mashed sweet potatoes through a fine-mesh sieve to remove any skin bits that might make the batter grainy.
In a medium bowl, whisk together the mashed sweet potatoes, 1.5 cups granulated sugar, 1 cup vegetable oil, 2 whole large eggs, 2 teaspoons vanilla extract, and 1 teaspoon baking soda. Mix until everything is fully combined and smooth. The batter should be thick but pourable—if it looks too stiff, don't worry, it'll come together as we add the dry ingredients.
👨🍳 Step 2: Combine Dry Ingredients and Vanilla Swirl
In a separate large bowl, sift together the 2 cups all-purpose flour, 2 teaspoons ground cinnamon, 0.5 teaspoon ground nutmeg, 1 teaspoon ground ginger, and 1 teaspoon salt. This sifting step is crucial—it prevents lumps and gives your cake that light, airy texture we're after. Make a well in the center of the dry ingredients and gently pour in the sweet potato mixture from the first bowl.
Using a spatula, fold everything together just until combined—you should still see some flour streaks. This prevents overmixing, which can make the cake tough. In a small bowl, whisk together the 1 box vanilla pudding mix, 0.5 cup milk, and 0.5 cup sour cream until smooth. This will be our swirl—set it aside for now.
🥘 Step 3: Create the Vanilla Swirl
Pour about half of the batter into a greased and floured 9-inch round cake pan (or two 8-inch pans if you prefer). Spoon the vanilla pudding mixture evenly over the top, then carefully dollop it into a spiral pattern using the back of a spoon. This creates those beautiful swirls when baked. Top with the remaining batter and gently swirl with a knife to create marbled patterns.
Here's the thing—don't overmix the swirls. You want visible streaks of vanilla pudding mixture throughout the batter. Tap the pan gently on the counter a few times to release any air bubbles that might have formed. This step is what gives this cake its signature look and flavor.
⏰ Step 4: Bake to Golden Perfection
Preheat your oven to 350°F and bake the cake for 35-40 minutes, or until a toothpick inserted into the center comes out clean. I know it seems like a long time, but this ensures that moist, tender crumb we're after. The cake should be golden on top with just a slight pull from the edges when you gently tug on it.
Don't open the oven door during the baking process—this can cause the cake to sink. If the top starts to brown too quickly, tent the pan with a piece of aluminum foil to prevent overbrowning while still allowing the cake to bake through. The center should be just set but still slightly springy to the touch.
🍽️ Step 5: Cool and Serve
Remove the cake from the oven and let it cool in the pan for 10 minutes. Then transfer it to a wire rack to cool completely. This cooling step is important—it allows the cake to set properly and prevents it from becoming gummy. Once fully cooled, you can frost it with your favorite vanilla or cream cheese frosting if desired, though the vanilla swirl is delicious enough on its own.
Slice into wedges and serve warm or at room temperature. You'll notice the moist, tender crumb with those beautiful swirls of vanilla throughout. The spices—cinnamon, nutmeg, and ginger—will give it a warm, comforting flavor that pairs perfectly with a cup of coffee or a glass of milk. Enjoy your cake while it's still moist and delicious!
Pro Tips For Making Betty Crocker Sweet Potato Cake
- Drain Sweet Potatoes Dry: The canned sweet potatoes will have syrup—pour it off and rinse the tubs under cold water. I learned this the hard way: skipping this step makes your cake dense and gummy instead of light and moist. Pat them dry with a paper towel too—wet tubs add extra liquid you don’t need.
- Whisk Eggs First: Beat the eggs until they’re fully blended before mixing them into the batter. I used to just crack them in and stir, but this recipe relies on the eggs for structure. A quick whisk ensures they’re smooth and evenly distributed—no surprise lumps in your cake.
- Skip Overmixing the Batter: Once the flour is added, mix just until combined—overdoing it develops gluten and turns your cake tough. I know, it’s tempting to make sure everything’s perfectly smooth, but this batter is forgiving. Stop when the dry ingredients disappear.
- Test Doneness with a Toothpick: The cake’s done when the center reads almost clean—just a few moist crumbs. I’ve pulled cakes too soon (dry, crumbly) and too late (soggy). A 205°F internal temp works, but the toothpick test is foolproof—no guesswork.
Pro cooking tips for betty crocker sweet potato cake
Sweet Potato Mixing Mastery
Mashing the sweet potatoes is where the magic starts—no lumps allowed. I use a potato masher and press the mixture through a fine-mesh sieve to remove any stubborn skin bits. This ensures your cake has that signature tender crumb without dry spots.
For extra smoothness, I blend the mashed sweet potatoes in a food processor for 10-15 seconds before mixing with wet ingredients. 💫
Spice Balance Secrets
The cinnamon, nutmeg, and ginger trio is non-negotiable for that warm, cozy flavor, but precision matters. I measure spices using a spice scoop (like the Penzeys brand) for accuracy—pre-ground spices lose potency fast.
For an extra boost, toast the spices in a dry skillet over low heat for 1 minute before adding to the batter to deepen their aroma.
Swirl Technique Pro Tips
The vanilla swirl is the showstopper—don't overmix! After pouring half the batter into the pan, I use a popsicle stick to create a well in the center for the pudding mixture.
Then, with a spoon, I gently drag the pudding through the batter in a zigzag pattern rather than a perfect spiral. This creates more visible swirls when baked. Tap the pan 3-4 times on the counter to release air bubbles before baking. ✨
Baking Time Precision
Baking at 350°F is critical—any hotter and the cake may dry out. I use an oven thermometer (like the Thermoworks brand) to confirm accuracy. For a 9-inch pan, bake for 35-40 minutes, but check at 30 minutes if your oven runs hot.
The cake is done when a toothpick comes out with just a few moist crumbs—not wet batter. Overbaking is the #1 mistake that turns moist cake into dry cake.
Pan Prep Matters
Grease your pan with vegetable oil (not butter) and dust with flour for easy release. I use a 9-inch round pan for a classic look, but 8-inch pans work too—just reduce baking time by 5-7 minutes.
For extra insurance, I line the pan with parchment paper cut to fit the bottom, then grease the paper. This prevents sticking and makes cleanup a breeze. 💡
Cooling Like a Pro
Let the cake cool in the pan for exactly 10 minutes—no more, no less. Then transfer to a wire rack to cool completely. This step is crucial for preventing a gummy texture.
If you're in a hurry, chill the cake in the fridge for 20 minutes instead of letting it cool at room temperature. For the best slices, use a serrated knife and dip it in hot water between cuts to get clean edges. 🔥

Frequently asked questions
Why does this sweet potato cake turn out so moist?
The secret lies in the combination of vegetable oil (not butter) and the natural moisture from sweet potatoes. The oil keeps the crumb tender, while the sweet potatoes add natural sweetness without drying out the cake. The vanilla pudding swirl also adds richness that locks in moisture. Plus, we avoid overmixing to preserve that light, airy texture.
Can I substitute regular potatoes for sweet potatoes?
You can use regular potatoes, but the flavor and texture will differ. Sweet potatoes provide a natural sweetness and moisture that regular potatoes lack. If substituting, use 1.5 cups mashed white potatoes and add 1 extra tablespoon of sugar to compensate for the lost sweetness. The cake will still be delicious but won't have that signature sweet potato warmth.
How do I make this cake vegan?
Replace the 2 eggs with 2 tablespoons ground flaxseed mixed with 6 tablespoons water (let sit for 5 minutes). Use vegan vanilla pudding mix and swap the sour cream for vegan sour cream or coconut yogurt. The milk can be replaced with almond or oat milk. The texture will be slightly denser but still moist and delicious.
What's the best way to store leftovers?
Wrap the cake tightly in plastic wrap and store at room temperature for up to 2 days. For longer storage, refrigerate for up to 5 days or freeze for 3 months. To reheat, slice and microwave for 10-15 seconds. The cake freezes beautifully—just thaw overnight in the fridge before serving. The vanilla swirl stays creamy even after freezing.
Can I bake this cake in a different pan size?
Yes! For an 8-inch pan, reduce baking time by 5-7 minutes (check at 30 minutes). For a 9x13-inch pan, bake for 30-35 minutes and reduce the batter by 25%. Always use the toothpick test—it should come out with just a few moist crumbs. Adjust oven racks to the middle position for even baking, regardless of pan size.
