This is a single-layer carrot cake made with freshly grated carrots, vegetable oil, and warm spices — it bakes in one 9-inch round pan and takes just over an hour start to finish. The oil-based batter keeps it genuinely moist for days, which is the real reason this cake has stayed popular. If you want a reliable, unfussy cake that works for a weeknight or a birthday, this is it.
Why this recipe works
Two things carry this cake. First, using oil instead of butter keeps the crumb tender even after a day or two in the fridge — butter-based cakes firm up when cold, oil-based ones don’t. Second, the combination of granulated and brown sugar does real work here: granulated sugar gives structure, while brown sugar adds a faint molasses depth that makes the cinnamon and nutmeg taste more rounded. Neither swap is accidental. Get those two things right and the rest of the recipe is straightforward.
What can go wrong
- Wet, sunken center: Carrots release moisture as they bake. If you grate them and let them sit in a bowl for 20 minutes before folding in, they’ll weep liquid into the batter and the center can sink. Grate them right before you need them.
- Dense, gummy texture: This almost always comes from over-measuring the flour. Spoon flour into your measuring cup and level it off — don’t scoop directly from the bag, which packs it down and adds up to 20% more flour than the recipe intends.
- Cake sticks to the pan: Greasing alone isn’t always enough. Line the bottom of your pan with a circle of parchment paper after greasing, then grease the paper too. It takes 30 seconds and guarantees a clean release.
- Spices taste flat: Ground spices lose potency fast once opened. If your cinnamon or nutmeg has been in the cupboard for more than a year, the cake will taste bland no matter how carefully you bake it. Buy fresh ones — it’s worth it.
- Cake overbrowns on top before the center sets: Oven hot spots are common. If the top looks dark at the 25-minute mark but a skewer still comes out wet, loosely tent the pan with foil and continue baking. Don’t open the oven before 25 minutes or the center may not set.
Ingredient notes
- Carrots: Pre-shredded carrots from a bag are too dry and too coarse — they don’t soften properly inside the cake. Use whole carrots and grate them on the fine or medium holes of a box grater.
- Vegetable oil: Any neutral oil works. Canola is fine. The recipe notes coconut oil as a swap — it does add a mild coconut flavor, so skip it if you want a straightforward spice cake.
- Brown sugar: Pack it firmly into the measuring cup. Loosely spooned brown sugar can leave you 20–25% short, which flattens the flavor noticeably.
- Cream cheese frosting: Not included in this recipe card, but it’s the standard pairing. Skip the powdered-sugar dusting — it disappears within an hour and isn’t worth the extra step.
Storage and make-ahead
Unfrosted, the cake keeps well wrapped at room temperature for up to 2 days. Once frosted with cream cheese frosting, it needs to go in the fridge — store it covered for up to 5 days. Cold cake straight from the fridge can taste a little dense, so let slices sit at room temperature for 15–20 minutes before serving. To freeze, wrap the unfrosted, fully cooled cake tightly in plastic wrap, then in foil, and freeze for up to 3 months. Thaw overnight in the fridge still wrapped. You can also bake the cake a day ahead, wrap it well, and frost it the next day — the flavor actually improves slightly overnight.

Equipment
- Mixing Bowls
- Whisk
- 9-inch round cake pan
- Oven
- Cooling Rack
Ingredients
- 1 ½ cups all-purpose flour Preferably unbleached.
- 1 tsp baking powder Ensure it's fresh for proper rise.
- ½ tsp baking soda Checks acidity.
- 1 tsp ground cinnamon
- ½ tsp ground nutmeg Freshly grated if possible.
- ¼ tsp salt
- ½ cup granulated sugar
- ½ cup brown sugar Packed.
- ¾ cup vegetable oil Or melted coconut oil for a hint of coconut flavor.
- 2 large eggs Room temperature.
- 1 tsp vanilla extract Pure extract preferred.
- 1 ½ cups grated carrots Freshly grated for texture.
Instructions
- Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan with butter or non-stick spray.
- In a large mixing bowl, whisk together the flour, baking powder, baking soda, cinnamon, nutmeg, and salt.
- In another bowl, mix the granulated sugar, brown sugar, and vegetable oil until combined. Add the eggs one at a time, whisking after each addition for a smooth mixture. Stir in the vanilla extract.
- Gradually add the wet mixture to the dry ingredients, stirring gently until just combined. Avoid over-mixing.
- Fold in the grated carrots, ensuring they are evenly distributed in the batter.
- Pour the batter into the prepared pan, smoothing the top with a spatula.
- Bake for 30-35 minutes, or until a skewer inserted in the center comes out clean with a few moist crumbs.
- Remove from oven and let the cake cool in the pan for 10 minutes, then transfer to a cooling rack to cool completely.
Notes
Tammy’s Tips
- Enhance the flavor by adding a handful of chopped walnuts or raisins to the batter.
- For a dairy-free version, substitute eggs with flax eggs.
- To intensify the spices, you might add a pinch of ground ginger or cloves.

Common questions
Do I really need to grate my own carrots?
Yes — pre-shredded carrots from a bag are too dry and won’t give you the same moisture in the finished cake. Freshly grated carrots release just enough liquid during baking to keep the crumb tender without making it soggy.
Can I make this in a different pan size?
You can bake it in an 8-inch square pan at the same temperature — start checking at 30 minutes. For a loaf pan, expect 45–55 minutes; tent with foil if the top browns early.
How do I know when the cake is actually done?
Insert a skewer or thin knife into the center — it should come out with just a few moist crumbs, not wet batter. The edges will also start to pull away slightly from the sides of the pan.
My batter looks very thick. Is that normal?
Yes, carrot cake batter is thicker than most — the grated carrots and oil make it dense before baking. Spread it evenly in the pan with a spatula and don’t worry about it being pourable.
Can I double the recipe to make a layer cake?
Doubling the recipe and dividing it between two 9-inch pans works well — bake time stays roughly the same at 30–35 minutes. Check both layers with a skewer since oven heat can vary between racks.
What if I don’t have baking powder and baking soda — can I use just one?
Don’t substitute one for the other in equal amounts — they aren’t interchangeable. Baking powder provides lift while baking soda neutralizes the acidity from the brown sugar; removing either will affect both the rise and the texture.
