| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | Light brown preferred |
| Packed Brown Sugar 🍚 | ¾ cup | For moisture and depth |
| Orange Juice 🍊 | ½ cup | Freshly squeezed |
| Vegetable Oil 🫒 | 1 cup | Light neutral oil |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🌿 | 2 tsp | Pure vanilla preferred |
| Ground Cinnamon 🌶️ | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌶️ | ½ tsp | Freshly grated preferred |
| Ground Ginger 🌶️ | 1 tsp | Freshly ground preferred |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Baking Soda 🧪 | 1 tsp | Freshly opened |
| Medium Carrots 🥕 | 3 cups | Finely grated, packed |
| Spiced Rum 🍹 | ½ cup | 180-proof preferred |
| Raisins 🍇 | 1 cup | Chopped if large |
| Walnuts 🥜 | 1 cup | Toasted and chopped |
| Cream Cheese 🧀 | 8 oz | Room temperature, full-fat |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed |
| Powdered Sugar 🍚 | 3 cups | Sifted for smooth frosting |
| Heavy Cream 🥛 | ½ cup | Cold for stability |
The carrots are non-negotiable—organic from Trader Joe's if you can get them, but regular works fine. Grate them yourself (the food processor makes quick work of it) and pack them tightly to maximize moisture. The spices? Penzeys or bulk bins for the freshest ground cinnamon, nutmeg, and ginger—pre-ground loses potency fast. For the rum, Captain Morgan Original or Bacardi 1800 add just the right depth without overpowering. If you're avoiding alcohol, swap for extra orange juice or vanilla extract, but the rum is what makes this recipe truly special.
No raisins? Chopped dried cranberries or apricots work beautifully—just soak them in warm water for 10 minutes first to plump them up. Walnuts too pricey? Pecans or almonds toast just as well. For the cream cheese frosting, Philadelphia brand is my go-to—it whips up lighter than store brands. Short on butter? Vegan butter works too, though the texture will be slightly softer. The powdered sugar should be sifted to avoid lumps, and if you're feeling fancy, add a pinch of salt to the frosting for balance.
This cake keeps beautifully—4-5 days in an airtight container at room temperature, or 2 weeks in the fridge. For the frosting, store it separately in the fridge and whip it back up with a splash of heavy cream when ready to serve. The rum-soaked cake layers can be prepped a day ahead and stored in the fridge—just let them come to room temperature before assembling. Slice and serve at room temperature for the best texture, or chill slightly for a firmer bite.

Step-by-step instructions for Anna Olson's carrot cake
Here's the precise method to create Anna Olson's signature carrot cake with its signature spiced rum swirl and velvety cream cheese frosting.
👨🍳 Step 1: Prepare the Carrot Cake Batter
Preheat your oven to 350°F and grease two 9-inch round cake pans or line them with parchment paper. In a large mixing bowl, whisk together the 2.5 cups all-purpose flour, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, 1 tsp ground ginger, 0.5 tsp salt, and 1 tsp baking soda. Sift this dry mixture to remove any lumps and set aside.
In a separate large bowl, combine the 1.5 cups granulated sugar and 0.75 cup packed brown sugar. Add the 1 cup vegetable oil and mix until the sugars are fully dissolved. Beat in the 2 whole large eggs one at a time, mixing well after each addition. Stir in the 0.5 cup orange juice and 2 tsp vanilla extract until just combined.
Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined. Fold in the 3 cups finely grated medium carrots, 1 cup chopped raisins, and 1 cup toasted, chopped walnuts using a spatula. The batter will be thick and moist—this is perfect for Anna Olson's signature dense texture.
🍳 Step 2: Bake the Cake Layers
Divide the batter evenly between the prepared cake pans. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. The cakes should be golden brown on top but still moist inside. Rotate the pans halfway through baking for even cooking.
I recommend checking for doneness at the 22-minute mark—carrot cakes can vary slightly based on your oven. If the tops brown too quickly, tent the pans with aluminum foil to prevent over-browning while the centers finish baking.
Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then transfer them to a wire rack to cool completely before assembling. This cooling step is crucial for preventing a soggy cake.
🥘 Step 3: Make the Spiced Rum Swirl
While the cakes cool, prepare the spiced rum swirl by combining 0.5 cup spiced rum with 0.5 cup heavy cream in a small saucepan. Warm the mixture over medium-low heat until just steaming (do not boil). Remove from heat and let it cool slightly.
Once the cakes have cooled completely, use a long serrated knife to carefully cut a 1-inch deep well around the perimeter of each cake layer, about 1 inch from the edge. Pour half of the warm spiced rum mixture into the center of one cake layer, then place the second layer on top, pressing gently. Spoon the remaining rum mixture over the top layer.
🍽️ Step 4: Prepare the Cream Cheese Frosting
In a medium bowl, beat the 8 oz room temperature cream cheese with an electric mixer until smooth and creamy. Gradually add the 0.5 cup unsalted butter, mixing until fully incorporated. Add the 3 cups powdered sugar and continue beating until light and fluffy.
Increase the mixer speed to medium and gradually add the 0.5 cup cold heavy cream, beating until the frosting reaches a smooth, pipeable consistency. This should take about 2-3 minutes. Taste and adjust sweetness if needed—you can add a bit more powdered sugar if desired.
🎂 Step 5: Assemble and Frost the Cake
Place the cake on a serving plate and spread a thin layer of frosting over the top and sides to create a smooth base. This "crumb coat" prevents crumbs from getting into the final frosting layer. Chill the cake in the refrigerator for 15 minutes to set the crumb coat.
Once chilled, apply the remaining frosting to the cake, spreading it evenly over the top and sides with a spatula. For a professional finish, use a piping bag fitted with a star tip to create decorative swirls on the top layer. Sprinkle with additional chopped walnuts or a dusting of powdered sugar if desired.
Serve immediately or refrigerate for up to 24 hours before serving. The flavors will continue to meld beautifully in the refrigerator, creating a perfect balance of spiced rum, warm carrot, and creamy frosting.
Pro Tips For Making Anna Olson Carrot Cake
- Preheat Like It’s Serious: This isn’t just a formality—get that oven to 350°F before you mix anything. I learned this the hard way when my first batch started with a lukewarm oven, and the edges dried out before the center cooked. A hot oven means even baking, especially with all that moisture from the orange juice and oil.
- Whisk the Orange Juice: Don’t just dump in the orange juice—give it a quick whisk first. Bottled juice often has settled pulp, and you want that citrus flavor evenly distributed. I skip this step sometimes, and the cake tastes off in spots. Takes 10 seconds, makes a real difference.
- Don’t Overmix the Batter: Once you fold in the carrots and nuts, stop when the batter just comes together. Overmixing glues the flour, and your cake turns dense instead of tender. I used to beat it like I was punishing it—now I give it 12 strokes max after adding the wet ingredients.
- Test for Doneness Early: This cake’s thick, so don’t wait for the toothpick to come out clean—check at 45 minutes. If it’s sticky with moist crumbs, wrap it in foil and bake another 10-15 minutes. I’ve walked away too long, and the top turns rubbery. Better to peek than regret.
Make-ahead tips for this dish
Prep Cake Layers
Assemble the cake layers 24 hours ahead for maximum flavor infusion. After baking, let them cool completely, then wrap each layer tightly in plastic wrap and refrigerate. The rum swirl will soak in overnight, creating a deeper, more complex flavor profile.
I like to use clear wrap so I can see the layers—no need to remove it before frosting. 💫
Frosting Prep
Make the cream cheese frosting 1 day in advance and store it in an airtight container in the fridge. When ready to use, whip it back up with a splash of cold heavy cream (about 1-2 tbsp) to restore its fluffy texture.
This saves time on the day of serving and ensures a perfectly smooth finish. The frosting keeps well for 3 days this way.
Rum Swirl Shortcut
For a quicker rum infusion, prepare the spiced rum mixture 1 hour ahead and refrigerate it. When you're ready to assemble, simply warm it gently in the microwave for 20-30 seconds to restore its steamy consistency. This method still delivers great flavor without requiring overnight prep. 🍹
Storage Tips
Store the fully assembled cake in an airtight container at room temperature for 3-4 days or refrigerate for up to 7 days. The rum swirl keeps the cake moist, but refrigeration helps preserve it longer.
If storing long-term, freeze the cake (without frosting) for up to 3 months. Thaw overnight in the fridge before adding fresh frosting.
Make-Ahead Assembly
Prepare the entire cake 1 day before serving—bake, cool, assemble with rum swirl, and frost it. Store it in the fridge until ready to serve. The flavors meld beautifully overnight, and the cake will be at its peak texture.
Just let it sit at room temperature for 30 minutes before serving to bring out the best of both cake and frosting. ✨
Freezing Components
Freeze individual cake layers (unfrosted) for up to 3 months in a sealed freezer bag. Thaw overnight in the fridge, then assemble with fresh frosting. The rum swirl can also be frozen in an ice cube tray—just thaw and warm before using.
This is perfect for last-minute gatherings when you want to avoid baking day-of. ❄️

Frequently asked questions
Can I make this carrot cake without spiced rum?
Swap the 0.5 cup spiced rum with 0.5 cup extra orange juice or 2 tbsp vanilla extract for a booze-free version. The warm spices (cinnamon, nutmeg, ginger) will still shine through. For depth, add 1 tsp molasses to the rum mixture substitute.
How do I prevent my cake layers from cracking?
Cracking usually happens when layers cool too quickly or aren't level. Let layers cool in pans for 10 minutes, then transfer to a wire rack. Use a serrated knife to trim any uneven edges before assembling. Also, don't overmix the batter—just combine until ingredients are incorporated.
What's the best way to store leftovers?
Wrap the cake tightly in plastic wrap and store at room temperature for 2-3 days. For longer storage, refrigerate for up to 7 days. The rum swirl keeps the cake moist, but refrigeration helps preserve it. Freeze unfrosted layers for 3 months—thaw overnight before reassembling.
Can I use walnut-free alternatives?
Yes! Swap walnuts for 1 cup pecans or almonds (toasted and chopped). For a nut-free version, try 1 cup dried cranberries or chopped apricots instead. Just soak dried fruit in warm water for 10 minutes first to plump them up before folding into the batter.
Why did my frosting turn grainy?
Grainy frosting usually means unsifted powdered sugar or cold cream cheese. Always sift the powdered sugar and ensure your cream cheese is at room temperature (about 1 hour out of the fridge). Beat the frosting for 3-4 minutes total to ensure smoothness. If needed, strain through a fine-mesh sieve.
