👩🍳 Step-by-Step Instructions
1. Prepare the Sweet Potatoes
If you haven’t already cooked the sweet potatoes, bake them at 400°F (200°C) for approximately 45–60 minutes, depending on their size.
They should be completely tender when pierced with a knife.
Allow them to cool enough to handle, remove the skins, and mash until smooth.
Measure 2 cups of mashed sweet potato and allow it to cool completely.
Tip: Baking the sweet potatoes rather than boiling them produces a thicker, more concentrated sweet potato puree.
2. Prepare the Pan
Preheat the oven to 350°F (175°C).
Generously grease a 10-inch Bundt pan, making sure to coat all the grooves.
Dust lightly with flour and tap out the excess.
A baking spray made specifically for cakes also works well.
3. Combine the Dry Ingredients
In a medium bowl, whisk together:
- Flour
- Baking soda
- Salt
- Cinnamon
- Nutmeg
Set aside.
4. Mix the Sweet Potato Mixture
In a large bowl, combine the cooled mashed sweet potatoes, sugar, eggs, oil or melted butter, and vanilla.
Whisk until smooth and well combined.
If using melted butter, make sure it has cooled slightly before adding it.
5. Combine the Batter
Gradually add the dry ingredients to the sweet potato mixture.
Stir gently until the flour is just incorporated.
Do not overmix.
If using chopped pecans, walnuts, raisins, or other optional additions, fold them in at this stage.
🍰 6. Bake the Cake
Pour the batter into the prepared Bundt pan.
Smooth the surface with a spatula.
Bake at 350°F (175°C) for 45–55 minutes.
Start checking around 45 minutes.
The cake is done when:
- A toothpick inserted into the thickest part comes out clean or with a few moist crumbs.
- The top springs back lightly when pressed.
- The cake begins pulling slightly away from the sides of the pan.
If the top becomes too dark before the center is finished, loosely cover it with foil.
7. Cool the Cake
Allow the cake to cool in the Bundt pan for approximately 15–20 minutes.
Carefully loosen the edges with a thin knife or spatula.
Invert onto a wire rack and allow it to cool for another 15–20 minutes.
For the best caramel finish, the cake can be slightly warm when the glaze is added, but it shouldn’t be hot.
🍯 How to Make the Warm Caramel Glaze
Place the butter and brown sugar in a small saucepan over medium-low heat.
Cook for approximately 2–3 minutes, stirring until the butter melts and the sugar dissolves.
Add the heavy cream or whole milk.
Continue cooking for another 2–3 minutes, stirring constantly.
Remove from the heat and stir in the vanilla and optional pinch of salt.
The glaze should be smooth and glossy.
🍯 Glaze the Cake
Place the cake on a serving plate.
Slowly spoon the warm caramel glaze over the top, allowing it to drip naturally down the sides.
For an extra-rich finish, let the first layer of glaze soak in for a few minutes, then add another light drizzle.
Sprinkle chopped toasted pecans over the glaze if desired.
⭐ Best Tips for a Perfect Sweet Potato Cake
Use thick sweet potato puree
The sweet potato mixture shouldn’t be watery. Excess moisture can make the cake heavy.
Bake the sweet potatoes
Roasting concentrates their natural sweetness and produces a thicker puree than boiling.
Cool the sweet potatoes
Hot sweet potatoes can affect the texture of the batter and may partially cook the eggs.
Don’t overmix
Once the flour is added, mix only until no dry streaks remain.
Grease the Bundt pan thoroughly
Sweet potato cake is naturally moist, so careful preparation helps prevent sticking.
Use fresh spices
Fresh cinnamon and nutmeg make a noticeable difference in this warmly spiced dessert.
Don’t overcook the caramel
The glaze only needs a few minutes. Overcooking can make it become too thick or grainy.
🌰 Best Ingredient Options
Butter vs. vegetable oil
Butter: Gives the cake a richer, more traditional flavor.
Vegetable oil: Produces an exceptionally moist cake and keeps the crumb soft for several days.
Fresh sweet potatoes
Freshly baked sweet potatoes provide the best flavor.
Canned sweet potatoes
You can use canned sweet potatoes in a pinch, but drain them extremely well and mash until smooth.
Pecans
Toasted pecans are especially delicious with sweet potato and caramel.
Whole milk vs. heavy cream
Heavy cream creates a richer caramel glaze, while whole milk produces a slightly lighter glaze.
🍂 Recipe Variations

☕ What to Serve With Sweet Potato Cake
This cake pairs beautifully with:
- ☕ Hot coffee
- 🍵 Black tea
- 🥛 Cold milk
- 🍦 Vanilla ice cream
- 🥛 Whipped cream
- 🌰 Toasted pecans
- 🍎 Warm apple compote
For a holiday dessert, serve a warm slice with vanilla ice cream and an extra spoonful of caramel glaze.
⏰ Make-Ahead Instructions
The cake can be baked 1 day ahead.
Allow it to cool completely, then cover tightly and keep at room temperature.
Prepare the caramel glaze separately and refrigerate it in an airtight container.
When ready to serve, gently reheat the glaze over low heat, stirring until smooth.
🧊 Storage
Store leftover cake in an airtight container.
At room temperature, it is best enjoyed within 2 days.
For longer storage, refrigerate for up to 4–5 days.
Because refrigeration can firm up the cake, allow slices to sit at room temperature for 20–30 minutes before serving.
🔥 Reheating
For a warm slice, place it on a microwave-safe plate and heat for approximately 10–15 seconds.
Add a little extra caramel glaze after warming.
For multiple slices, cover loosely with foil and warm in a 300°F (150°C) oven for approximately 10 minutes.
❄️ Freezing
The unfrosted cake freezes very well.
Wrap the completely cooled cake tightly in plastic wrap, then place it in a freezer-safe bag or wrap it in foil.
Freeze for up to 2–3 months.
Thaw overnight in the refrigerator or several hours at room temperature.
Prepare fresh caramel glaze before serving for the best texture.
Individual slices can also be wrapped and frozen separately.
⚠️ Common Mistakes to Avoid
1. Using watery sweet potatoes
Excess water can make the cake heavy and gummy.
2. Adding hot sweet potato puree
Allow the mashed sweet potatoes to cool before making the batter.
3. Overmixing the flour
This can create a tougher crumb.
4. Under-greasing the Bundt pan
Make sure every groove is thoroughly coated.
5. Overbaking
Start checking at 45 minutes. A few moist crumbs on the toothpick are fine.
6. Pouring the glaze over a very hot cake
The glaze can become too runny and slide completely off.
7. Cooking the caramel too aggressively
Keep the heat at medium-low and stir frequently for a smooth glaze.

❓ Frequently Asked Questions
Can I use canned sweet potatoes?
Yes. Drain them very well before mashing. Avoid canned sweet potatoes packed in syrup unless you reduce the added sugar accordingly.
Can I use pumpkin instead of sweet potato?
You can, but the flavor and texture will change. Sweet potato has a naturally sweeter, denser texture that gives this cake its distinctive character.
Should I use butter or oil?
Both work well. Butter provides richer flavor, while oil generally produces a softer and moister crumb.
Can I add pecans?
Absolutely. Pecans are one of the best additions to this cake. Try ½–¾ cup toasted chopped pecans in the batter.
Can I make this cake without a Bundt pan?
Yes. Two standard 9×5-inch loaf pans can work, although the baking time will need to be adjusted. Begin checking around 40–45 minutes.
Why is my sweet potato cake gummy?
The most common causes are excess moisture in the sweet potatoes, underbaking, or adding too much liquid. Make sure the sweet potato puree is thick and bake until the center is fully set.
Can I make the caramel glaze ahead?
Yes. Refrigerate it in an airtight container for up to 4 days. Reheat gently over low heat and stir until smooth before using.
