This is a single-layer pumpkin spice cake made with canned pumpkin puree, vegetable oil, and a straightforward spice blend of cinnamon, nutmeg, and ginger. It bakes in one 9-inch round pan in about 40 minutes and comes out dense, moist, and genuinely flavorful. The honest reason to make it: it holds up well over several days, which makes it one of the more practical cakes to have in your repertoire when you’re baking ahead for a gathering.
Before you start
Two things actually matter here. First, measure your pumpkin puree carefully — a heaping cup instead of ¾ cup adds too much moisture and the center won’t set properly in 40 minutes. Use a dry measuring cup and level it off. Second, don’t skip fully greasing and flouring the pan, including the bottom. Pumpkin cakes are stickier than standard butter cakes because of the puree’s natural sugars; a light coating isn’t enough. Parchment on the bottom plus greased and floured sides is the most reliable approach if you plan to turn the cake out cleanly for frosting.
Storage and freezing
Unfrosted, this cake keeps well at room temperature under a cake dome or wrapped tightly in plastic for up to 3 days — the oil-based batter actually improves the texture slightly on day two. If you’ve added cream cheese frosting, refrigerate it and plan to use it within 4 days; bring slices to room temperature for 20 minutes before serving or the crumb will feel dense. For longer make-ahead planning, freeze the unfrosted cake layer: wrap it tightly in two layers of plastic wrap, then foil, and freeze for up to 2 months. Thaw overnight in the refrigerator still wrapped, then finish at room temperature before frosting. Skip the garnish — not worth the extra dish when the cake looks clean and the frosting does the work.
What can go wrong
- Sunken center: Usually caused by opening the oven door before 30 minutes or by underbaking. The pumpkin puree keeps the batter looking wet even when it’s nearly done — trust the toothpick test over visual cues.
- Gummy, dense texture: Overmixing after the dry ingredients go in develops gluten and tightens the crumb. Fold just until the flour disappears; a few small streaks are fine.
- Cake sticks to the pan: Even with greasing, if the cake is turned out before the 10-minute rest, the bottom layer tears. Let it sit in the pan on a rack for the full 10 minutes — it firms up and releases cleanly.
- Flat, pale top: If your baking soda or baking powder is more than 6 months open, they may have lost potency. Test baking soda by dropping a pinch in hot water — it should fizz immediately. Stale leaveners produce a flat cake with a pale, slightly tacky surface.
- Spice flavor too faint after baking: Ground spices fade in storage. If your cinnamon, nutmeg, or ginger have been open for over a year, increase each by about 25% to compensate — the recipe has enough sweetness to handle it.
Pumpkin Spice Cake
Equipment
- Mixing Bowls
- Whisk
- 9-inch round cake pan
- Oven
- Cooling Rack
- Spatula
Ingredients
- 1 ½ cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- 1 teaspoon ground cinnamon preferably Ceylon
- ½ teaspoon ground nutmeg
- ¼ teaspoon ground ginger
- ¼ teaspoon salt
- 1 cup granulated sugar
- ½ cup packed brown sugar
- ¾ cup unsweetened pumpkin puree
- ½ cup vegetable oil
- 2 large eggs room temperature
- 1 teaspoon vanilla extract
Instructions
- Preheat the oven to 350°F (175°C). Grease and flour a 9-inch round cake pan, ensuring every side is coated to prevent sticking.
- In a mixing bowl, whisk together the all-purpose flour, baking soda, baking powder, cinnamon, nutmeg, ginger, and salt. Set aside.
- In a separate large mixing bowl, combine the granulated sugar, brown sugar, and pumpkin puree. Stir until smooth and thoroughly combined.
- Gradually add the vegetable oil, followed by the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
- Gently fold the dry ingredients into the wet mixture, taking care not to over-mix. The batter should be smooth with a few small lumps.
- Pour the batter into the prepared cake pan. Smooth the top with a spatula to ensure even baking.
- Bake for 35-40 minutes, or until a toothpick inserted into the center of the cake comes out clean. Let the cake cool in the pan for 10 minutes, then transfer to a cooling rack to cool completely.
Notes
Lori’s Tips
- For a richer flavor, consider adding a pinch of cloves to the spice mix.
- If you prefer a lighter cake, substitute half of the vegetable oil with unsweetened applesauce.
- To ensure even baking, rotate the cake halfway through baking.

FAQ
Can I make this cake the day before I need it?
Yes — this is one of the better cakes to bake a day ahead. Wrap the cooled, unfrosted cake tightly in plastic and leave it at room temperature overnight; the texture is actually slightly better the next day. Frost it the morning of your event.
Can I use fresh pumpkin instead of canned?
You can, but the results are less consistent. Fresh pumpkin puree often has more water than canned, which can make the cake too wet and slow the bake time. If you use it, drain the puree in a fine mesh strainer or cheesecloth for at least 30 minutes first.
Does this recipe work as a double layer cake?
It does — double the recipe and divide the batter evenly between two greased 9-inch pans, checking for doneness at 30–35 minutes. Cream cheese frosting between the layers and on top works well and holds up without refrigeration for a few hours at a cool room temperature.
Can I bake this in a different pan size?
A 9×5-inch loaf pan works and gives you something closer to a pumpkin bread shape; start checking at 50 minutes. An 8-inch square pan also works at roughly the same bake time as the round. Avoid a bundt pan with this recipe — the batter is too dense and it tends to stick in the crevices.
How do I know the cake is fully baked and not just set on the outside?
Insert a toothpick into the very center — it should come out clean or with a dry crumb or two, not wet batter. The top of the cake should also spring back lightly when pressed in the center. If the edges look done but the center still jiggles slightly, give it 5 more minutes and test again.
