Carrot cake with raisins stays moist for days when you soak the raisins for about 10 minutes before they go into the batter.
Dry raisins pull water from the crumb while the cake bakes and keep pulling as it rests, so an unsoaked cake can taste fine on day one and crumbly by day two.
I learned that the slow way, because my first carrot cake with raisins looked right coming out of the oven and turned dry overnight.
I blamed my oven for weeks before I noticed the real cause had been sitting in the pan the whole time.
Here’s what this guide covers: whether raisins belong in carrot cake at all, the full ingredient list with pineapple and walnuts, the 10-minute soak, five baking steps, frosting by pan style, and the mistakes that dry out the crumb.
Is Carrot Cake with Raisins Worth Making?
Carrot cake with raisins is worth making if you like small, chewy pockets of sweetness in a soft spiced cake.
Raisins pair well with pineapple and walnuts because each adds a different texture, chewy, juicy, and crunchy, but nothing else in the recipe depends on them, so you can leave them out for a smoother crumb.
Many old-fashioned carrot cake recipes include raisins, and this one keeps them for that reason. If someone at your table dislikes them, that alone is a good enough reason to skip them.
Dark raisins give a deeper, caramel-like sweetness, while golden raisins taste lighter and slightly tangier.
A carrot cake with golden raisins looks a little brighter when sliced, and both kinds work at the same measurement.
After more than nine years of baking and a degree in Baking and Pastry Arts, I’ve tested this cake with dry raisins and soaked ones more times than I can count.
The soaked version is the one that still tastes fresh on day three.
What Do You Need for Carrot Cake with Raisins?
Carrot cake with raisins is an oil-based, spiced cake that gets most of its sweetness and moisture from raisins, crushed pineapple, and grated carrot.
That lets the added sugar stay lower than in many classic versions while the crumb stays soft.
Ingredients for Carrot Cake with Pineapple and Raisins
This recipe makes one 9×13-inch cake or two 9-inch layers, enough for 12 to 16 servings. I group everything by type before I start, so nothing gets missed halfway through.
- Wet: 3 large eggs at room temperature, ¾ cup (180 ml) neutral oil, and 1 can (8 ounces or 227 g) crushed pineapple with its juice
- Sugars: ¾ cup (150 g) packed brown sugar and ½ cup (100 g) granulated sugar
- Dry: 2 cups (250 g) all-purpose flour, 2 teaspoons ground cinnamon, 1½ teaspoons baking soda, and ½ teaspoon salt
- Mix-ins: 2 cups (200 g) finely grated carrots from about 4 medium carrots, plus ¾ cup (110 g) raisins, soaked and drained
- Optional: ¾ cup (85 g) chopped walnuts and ½ cup (40 g) unsweetened shredded coconut
The sugar here totals 1¼ cups, well below the 2 cups that many classic carrot cakes call for, because the raisins and pineapple bring sweetness of their own.
A carrot cake with raisins and walnuts is the classic pairing, and unsweetened coconut adds chew without pushing the sweetness higher.
Pineapple also brings acid, and NC State’s explainer on how baking soda reacts shows that soda releases carbon dioxide almost as soon as it meets an acid.
That reaction, helped along by the brown sugar, lifts this cake without any baking powder, so keep the full can of pineapple and its juice in the batter.
Raisins and warm spice work the same way in our spiced healthy apple bread, which lists them as an optional add-in.
This cake contains wheat and eggs; the walnuts add a tree nut, and the frosting adds milk, so adjust the add-ins for anyone with a food allergy.
How to Prepare the Raisins
Cover the raisins with hot water, brewed black tea, or orange juice and let them sit for 10 minutes.
Water keeps the flavor neutral, orange juice adds a citrus note that suits cream cheese frosting, and tea gives a faint, pleasant bitterness that offsets the sweet fruit.
Hard, dry raisins need the full 10 minutes, while soft, fresh raisins only need about 5, so start the soak before you grate the carrots and it adds no time on a busy weeknight.
The same step works for the golden raisin add-in in our carrot cake muffins recipe, where plump raisins keep each muffin soft.
Drain the raisins well and pat them dry with a towel, because extra water thins the batter and can make them sink. You want raisins that look plump and feel soft but leave no wet patch on the towel.
How Do You Make Carrot Cake with Pineapple and Raisins?
To make carrot cake with pineapple and raisins, heat the oven to 350°F (175°C), mix the wet ingredients, stir in the dry ingredients until combined, and fold in the carrots, soaked raisins, and nuts.
Bake until a skewer comes out with a few moist crumbs, then cool the cake completely before frosting.
Step 1: Mix the Wet Ingredients
Heat the oven to 350°F (175°C) and grease and line your pan before you start, so the batter can go in as soon as it’s mixed.
Whisk the eggs, oil, and both sugars until smooth, then stir in the crushed pineapple and its juice.
The mixture only needs to look even, not fluffy, because the oil carries the moisture in this cake rather than air whipped into the eggs.
Step 2: Add the Dry Ingredients
Add the flour, cinnamon, baking soda, and salt to the wet mixture and stir gently until no dry flour remains. Stop there, because extra stirring once the flour goes in makes the cake tough.
Step 3: Fold in the Add-Ins
Toss the drained raisins and the walnuts with a spoonful of the measured flour so they don’t clump together in the batter.
Fold them in with the grated carrots and the coconut, if using, and stop as soon as they’re evenly spread.
Step 4: Bake by Pan Size
Pour the batter into the prepared pan and smooth the top. Baking time depends on the pan, so start checking at the low end of each range:
- Two 9-inch round layers: 25 to 35 minutes
- One 9×13-inch pan: 35 to 45 minutes
- One 10- to 12-cup Bundt pan, greased and floured in every ridge: 50 to 60 minutes
Step 5: Check and Cool
Test the center with a skewer rather than relying on the clock, and take the cake out when the skewer shows a few moist crumbs.
Wet batter on the skewer means it needs another 3 to 5 minutes.
Let the cake rest in the pan for 10 to 15 minutes, then turn layers or a Bundt out onto a rack. A 9×13 cake can cool completely in its pan, which makes it the easiest style to frost and carry.
With the cake cooled, the pan you chose decides how much frosting it needs.
Frosting and Pan Styles for Carrot Cake
Cream cheese frosting suits this cake best, because its tang balances the sweetness of the raisins and pineapple.
How much you make, and whether you frost or glaze, depends on the pan, so match your topping to the style you baked.
| Pan or Finish | Best Topping | How to Make It | Why It Works |
| 9×13-inch cake | Cream cheese frosting | Beat 8 ounces (226 g) softened cream cheese with 4 tablespoons (57 g) softened butter, then add 2 cups (240 g) powdered sugar and 1 teaspoon vanilla | Covers the top in a thick, tangy layer |
| Two 9-inch layers | Cream cheese frosting | Make about 1½ times the 9×13 amount | Gives enough to fill and cover both layers |
| Bundt cake | Thin glaze | Whisk 1 cup (120 g) powdered sugar with 2 to 3 tablespoons milk or orange juice, then drizzle over the cooled cake | Thick frosting slides into the ridges and pools at the base |
| Walnuts in the batter | Chopped walnuts | Fold them in with the carrots | Add crunch in every bite, though they soften a little from the moisture |
| Walnuts on top | Toasted chopped walnuts | Toast in a dry skillet for a few minutes, then scatter over the frosting | Stay crisp and taste fuller and nuttier |
What Mistakes Make Carrot Cake with Raisins Dry or Dense?
Most carrot cake with raisins turns dry because the raisins went in dry, and most turns dense because of overmixing or too much pineapple juice.
Soak and drain the raisins, measure the pineapple as written, and stop stirring once the flour disappears.
- Raisins added dry: Unsoaked raisins pull moisture from the crumb as the cake bakes and rests, so soak them for 10 minutes before they go in.
- Raisins sinking to the bottom: This usually means they went in wet or extra juice thinned the batter, and a loose batter can’t hold them up however well they’re coated in flour. Pat them dry and skip any extra splash of pineapple liquid.
- Overmixing after the flour goes in: Extra stirring develops gluten and makes the cake dense, so stop as soon as no dry flour shows.
- Gummy center: The cake came out of the oven too early, so give it another 3 to 5 minutes and test again.
- Dry, dark edges: The cake stayed in too long. Press the top lightly before testing, because a cake that springs back and leaves moist crumbs on the skewer is ready.
Keeping Carrot Cake with Raisins Moist After Day One
A frosted carrot cake with raisins keeps best covered in the refrigerator for up to 4 days, because cream cheese frosting is perishable.
Press plastic wrap against any cut edge so the exposed crumb doesn’t dry out, and let slices sit out about 20 minutes before serving.
Don’t leave the frosted cake out for long at a party; under the ideal case, limit perishable food to 2 hours at room temperature, or 1 hour above 90°F.
A Ten-Minute Soak Makes the Difference
Carrot cake with raisins stays soft past the first day when the raisins are soaked, the pineapple is measured, and the batter is mixed only until the flour disappears.
The rest comes down to your oven, and every oven has habits of its own.
Testing one change at a time is how I’ve worked since my start in a small-town bakery, and it works at home too.
Jot down the pan, the bake time, and how the crumb felt, and by your third cake you’ll have a version tuned to your kitchen.
Put the raisins in to soak before you grate the carrots, and bake this cake as written this weekend.
Frequently Asked Questions
Can You Make Carrot Cake with Raisins and Buttermilk?
Yes, swap about ½ cup of the crushed pineapple for buttermilk to get a tangier, more tender crumb. Both are acidic, so replace rather than add, or the batter turns loose and gummy.
Why Use Oil Instead of Butter in Carrot Cake?
Oil stays liquid in the fridge, so chilled slices stay soft, while butter firms up as it cools. For a little butter flavor, swap up to ¼ cup of the oil for melted butter.
