It's Monday, October 20th here in Austin, Texas. The air finally has a hint of a real chill, which means my kitchen has officially switched over to full fall baking mode. While pumpkin spice seems to get all the glory, my true heart belongs to the deep, comforting flavour of sweet potato. This recipe is my absolute treasure. It's not quite a traditional pound cake (it's far moister) and not quite a steamed pudding (it slices perfectly). It's this magical, elegant hybrid-a Sweet Potato Pudding Cake- with a plush, velvety crumb that just melts in your mouth, infused with warm cinnamon and nutmeg. If you're baking for a fall celebration, it pairs beautifully with a batch of Pumpkin Pie Cookies or even a slice of the Thanksgiving Piecaken if you're going all out.
It's the ultimate bake where pure comfort meets elegance. I love serving it after something savory and cozy like Cranberry Apple Twice-Baked Sweet Potatoes - it rounds out a fall menu with just the right touch of sweetness and spice.

Tested in my Austin kitchen: The 4-hour rest period mentioned in the instructions is not just a suggestion-it's essential! I tried slicing this loaf after only 2 hours (I was too impatient!), and while delicious, the crumb was slightly gummy. Letting it rest completely transforms the texture, allowing the moisture to settle and creating that perfect, velvety pound cake finish. Trust the process!
A Velvety Crumb for Fall Baking
What makes this cake so special is the method. By roasting the sweet potatoes first, you get a deep, concentrated, caramelized flavour that you simply cannot achieve by boiling. This rich puree is then folded into a classic pound cake batter, created using the "creaming method" for a fine, tender crumb. It's the perfect, sophisticated loaf to serve on a holiday table (hello, Thanksgiving planning!) or just to enjoy with a cup of coffee on a cozy afternoon.
Why You'll Love This Recipe
- Velvety, Moist Crumb: The combination of roasted sweet potato, butter, and milk creates an incredibly plush, tender, and moist pound cake texture.
- Deep, Rich Flavour: Roasting the sweet potatoes (instead of boiling) caramelizes their sugars and provides a deep, complex flavour that pairs beautifully with cinnamon and nutmeg.
- Classic, No-Fuss Technique: This recipe uses the traditional creaming method, which is straightforward and guarantees a reliable, high-quality result.
- Perfect Make-Ahead: The flavours actually improve on day two, making this an ideal bake to prepare in advance for holiday gatherings or brunch.
Ingredients
Here's what you'll need for this cozy loaf. For the full list with precise measurements, see the recipe card at the end of the post!
- Sweet Potatoes: You must use roasted sweet potatoes, not boiled or canned. Roasting removes moisture and concentrates the flavour. I find the Jewel or Garnet varieties (the ones with reddish-orange skin) provide the best colour and moisture.
- Unsalted Butter: Use full-fat, softened to room temperature. This is crucial for the creaming step.
- Sugar: Granulated sugar provides the main sweetness and structure.
- Eggs: Four large eggs, also at room temperature. This helps them incorporate smoothly into the batter for a stable emulsion.
- Vanilla Extract: Use pure vanilla extract, not imitation, for the best flavour.
- Spices: A classic, warm blend of ground cinnamon and ground nutmeg.
- Flour: Simple all-purpose flour, spooned and levelled for accuracy.
- Leavening: Baking powder provides the lift.
- Milk: Whole milk is preferred for its fat content, also at room temperature.
- Salt: A necessary ingredient to balance the sweetness and enhance all the other flavours.
How to Make Sweet Potato Pound/Pudding
This recipe is simple, but success lies in the details. Be sure to use room temperature ingredients for the best, most even crumb.
Step 1: Roast the Sweet Potatoes
First, roast your sweet potatoes. Preheat the oven to 400°F (200°C). Prick the sweet potatoes all over with a fork, place them on a baking sheet, and roast for 45-60 minutes until completely tender all the way through. Let them cool until you can handle them, then peel the skins off (they should slide right off) and mash the flesh until perfectly smooth. Set aside 2 cups of the mash for the recipe.
Step 2: Prep and Cream Butter & Sugar
Lower the oven temperature to 350°F (175°C). Thoroughly grease and flour a 9×5-inch loaf pan.
In the bowl of a stand mixer fitted with the paddle attachment, or in a large bowl with a handheld mixer, add the softened butter and granulated sugar. Cream together on medium speed for 3-4 minutes. The mixture should become visibly pale, light, and fluffy.
Step 3: Add Eggs and Sweet Potato
With the mixer on low, add the room-temperature eggs one at a time, making sure each egg is fully incorporated before adding the next. Scrape down the sides of the bowl.
Fold in the 2 cups of mashed sweet potato, the vanilla extract, ground cinnamon, ground nutmeg, and salt. Mix on low until the batter is combined and a beautiful, uniform orange colour.
Step 4: Alternate Wet and Dry Ingredients
In a separate medium bowl, whisk together the all-purpose flour and baking powder.
With the mixer on its lowest speed, add the dry ingredients to the sweet potato mixture in three parts, alternating with the room-temperature milk in two parts. Always begin and end with the flour mixture. (Example: ⅓ flour, ½ milk, ⅓ flour, ½ milk, final ⅓ flour). Mix only until each addition is just combined. Do not overmix.
Step 5: Bake and Cool (The Hard Part!)
Pour the thick batter into your prepared loaf pan and smooth the top with a spatula.
Bake for 55-65 minutes. The cake is done when a wooden skewer or toothpick inserted into the very centre comes out with a few moist crumbs, but no wet batter.
Cool the cake in the pan on a wire rack for 15 minutes. After 15 minutes, carefully invert the loaf onto the wire rack, flip it right-side up, and let it cool completely. For the absolute best "pudding" texture, let the cake rest for at least 4 hours before slicing.
Common Mistakes to Avoid
- Using Boiled or Canned Sweet Potatoes: This is the biggest pitfall. Boiling or canning adds water to the potatoes, which will make your pound cake dense, heavy, and potentially soggy rather than velvety. Roasting is essential.
- Using Cold Ingredients: If your butter, eggs, or milk are cold, they won't emulsify properly. The batter will look curdled, and the final cake may be heavy or greasy.
- Slicing While Warm: This cake is incredibly moist and "pudding-like." It must cool completely and rest for several hours for the crumb to set. Slicing it hot will result in a gummy, dense texture.
Tips and Tricks for Success
- Room Temperature is Key: I take my butter, eggs, and milk out of the fridge a full hour before I start. This is the single most important step for a fine-textured pound cake.
- Spoon and Level Your Flour: To avoid a dry, heavy cake, spoon your flour into the measuring cup and level it off. Scooping directly from the bag packs the flour down, adding too much.
- Smooth Mash: For a truly velvety crumb, make sure your roasted sweet potato mash is as smooth as possible. You can even pass it through a ricer or give it a quick pulse in a food processor (before adding to the batter) to remove any strings.
- The Creaming Method: The act of beating butter and sugar until "pale and fluffy" is a physical leavening step. As baking experts at America's Test Kitchen explain, this process forces air into the fat, creating tiny bubbles that, when combined with leaveners, result in a fine, tender crumb. Don't rush this step!
Variations
This loaf is a stunning base for other flavours, especially for the holidays!
- Add a Glaze: A simple vanilla glaze (powdered sugar + milk + vanilla) or a maple-cinnamon glaze would be delicious.
- Add Nuts: Fold in 1 cup of chopped, toasted pecans or walnuts along with the last addition of flour.
- Add a Kick: Add 2 tablespoons of bourbon or dark rum to the batter along with the vanilla for a deeper, richer flavour.
- Add Chocolate: Fold in 1 cup of mini chocolate chips (semi-sweet or white) at the end.
How to Serve
This Sweet Potato Pound Cake is elegant all on its own, but it's also a fantastic canvas.
- Serve a simple slice at room temperature with a hot cup of coffee or tea for a perfect fall breakfast or snack.
- Toast a slice and spread it with salted butter.
- Serve as a dessert topped with a dollop of whipped cream, a scoop of vanilla bean ice cream, or a drizzle of caramel sauce.
- This is a perfect addition to a Thanksgiving or Christmas dessert table.
Make Ahead and Storage
This cake is an excellent make-ahead bake, as the flavour and texture are even better on day two!
- Make Ahead: Bake the cake 1-2 days in advance.
- Storage: Store the completely cooled cake in an airtight container (or tightly wrapped in plastic) at room temperature for up to 4 days. You can also store it in the refrigerator for up to a week.
- Freezing: This cake freezes beautifully. Wrap the entire cooled loaf (or individual slices) in plastic wrap, followed by a layer of aluminum foil. Freeze for up to 3 months. Thaw overnight at room temperature.
Recipe Notes / What I Learned
The name "Pound/Pudding" in the original title is the perfect description. It bakes up with the fine, even, velvety crumb of a classic pound cake (thanks to the creaming method), but the high moisture content from the roasted sweet potato gives it an internal texture that is almost as dense and rich as a traditional steamed pudding. It's truly the best of both worlds.

FAQs
Can I use canned sweet potato puree?
I highly recommend against it. Canned puree is much more watery and has a thinner, more "steamed" flavour than roasted. Using it will likely result in a dense, overly soggy cake. Roasting is key!
Can I make this into muffins?
Yes, this batter should adapt well. Line a standard 12-cup muffin tin and fill the cups ¾ full. Bake at 350°F (175°C) for 22-28 minutes, or until a toothpick comes out clean.
Why did my cake sink in the middle?
This is often a sign of underbaking. Because the cake is so moist, it needs to be baked until a toothpick inserted in the very center comes out with just a few moist crumbs, not wet batter. It could also be from opening the oven door too early, causing the delicate structure to collapse.
