This 1kg plum cake recipe delivers layers of spiced fruit and buttery crust that taste like a bakery secret. The magic lies in balancing tender crumb with juicy plums and warm spices, creating a cake that’s rich yet light—perfect for special occasions or weekend treats.
I’ve perfected this recipe over years of baking, ensuring every slice delivers that ideal texture and flavor harmony.
The secret starts with a buttery crust that encases layers of moist cake and spiced plums, baked just until golden. This recipe uses a simple yet effective technique: steaming the plums before layering them, which preserves their juiciness and intensifies their natural sweetness.
The spices—cinnamon, nutmeg, and cardamom—add warmth that complements the fruit beautifully.
By the time it emerges from the oven, you’ll have a golden, fragrant cake with layers that stay moist for days. The buttery crust adds a satisfying crunch, while the spiced plum filling creates pockets of fruity goodness in every bite.
This cake is elegant enough for celebrations but simple enough for a weekend baking project.
For those with dietary preferences, variations include gluten-free flour blends and vegan butter substitutes—though the classic version remains unbeatable. Let’s get baking!
Ingredients for 1kg plum cake
Buttery layers, spiced plums, and golden crust—this 1kg cake delivers bakery-quality perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 4 cups | Sifted for even texture |
| Unsalted Butter 🧈 | 1 ½ cups | Cold, cubed for crust |
| Granulated Sugar 🍚 | 1 ½ cups | Superfine preferred |
| Large Eggs 🥚 | 4 whole | Room temperature |
| Fresh Plums 🍑 | 3 lbs | Pitted, halved, steamed |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | 1 tsp | Freshly grated nutmeg |
| Ground Cardamom 🌿 | ½ tsp | Lightly toasted |
| Vanilla Extract 🍯 | 1 tbsp | Pure Madagascar preferred |
| Baking Powder 🧂 | 2 tsp | Double-acting type |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Heavy Cream 🥛 | ½ cup | Cold for crust |
| Powdered Sugar 🍚 | ¼ cup | For dusting |
| Lemon Zest 🍋 | 1 tbsp | Freshly grated |
The butter and flour form the foundation of this cake’s signature crust. European-style butter (like Plugrá or Land O’Lakes) works best—it has higher fat content for that rich, flaky texture. For the flour, King Arthur or Gold Medal are excellent choices, but any all-purpose will do. The key is keeping everything cold until the final moment—this prevents the butter from melting prematurely. If your kitchen runs warm, chill the dough for 30 minutes before baking. The plums should be ripe but firm; Santa Rosa or Italian prune plums are ideal for their balance of sweetness and acidity. If you can’t find fresh plums, frozen works in a pinch—just thaw and drain them thoroughly.
Substitutions can work, but with caution. Vegan butter (like Miyoko’s) can replace the unsalted butter, though the crust will be slightly less flaky. For the spices, if you don’t have cardamom, allspice at half the amount adds depth. The vanilla extract is non-negotiable—imitation won’t cut it here. For the sugar, superfine is ideal, but if you only have granulated, pulse it in a food processor for a few seconds to break it down. The heavy cream can be swapped for full-fat coconut cream, though the texture will differ slightly. If you’re baking at high altitude, reduce the baking powder by one-quarter teaspoon to prevent over-rising.
This cake keeps beautifully for 5 days at room temperature, wrapped tightly in plastic. For longer storage, freeze individual slices wrapped in parchment and plastic—up to 3 months. The crust stays crisp, while the cake layers remain moist. To reheat, warm at 300°F for 10 minutes to restore the buttery aroma. I always bake an extra layer—it disappears faster than you’d think. The spiced plum filling can be made ahead and stored in the fridge for 2 days before assembling the cake.

Step-by-step instructions for 1kg plum cake
Here’s how to create a perfectly layered plum cake with a rich buttery crust and spiced fruit filling.
Prepare the Plum Filling
In a large saucepan, combine the 3 lbs of fresh plums with the 1.5 cups of granulated sugar, 2 tsp of ground cinnamon, 1 tsp of ground nutmeg, 0.5 tsp of ground cardamom, and the 1 tbsp of lemon zest. This spice blend creates the signature warmth of a proper plum cake.
Bring the mixture to a gentle simmer over medium heat, stirring occasionally. Let it cook for 15-20 minutes until the plums soften and the liquid reduces by about half. The filling should coat the back of a spoon and have a thick, jam-like consistency. This reduction is crucial for preventing a soggy cake.
Remove from heat and let the plum mixture cool completely. Once cooled, stir in the 1 tbsp of vanilla extract. This step develops the flavors and ensures the filling is ready for layering without making the cake too moist.
Create the Cake Layers
Preheat your oven to 350°F (175°C). In a large mixing bowl, cream together the 1.5 cups of unsalted butter and the remaining 1.5 cups of granulated sugar until light and fluffy. This should take about 3-5 minutes using an electric mixer on medium speed.
In a separate bowl, whisk together the 4 cups of sifted all-purpose flour, 2 tsp of baking powder, and 0.5 tsp of salt. Gradually add the dry ingredients to the butter mixture, alternating with the 4 whole large eggs. Begin and end with the flour mixture to ensure even distribution. Mix just until combined—overmixing develops gluten and makes the cake dense.
Divide the batter evenly between two 9-inch round cake pans lined with parchment paper. Spread the cooled plum filling evenly over the first layer in one pan. Top with the second layer of batter. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
Assemble and Bake the Cake
Once both layers are baked and cooled, carefully remove them from the pans. Place the first layer on a serving plate and spread a thin layer of the 0.5 cup of heavy cream over it. This cream layer acts as a glue and adds moisture to the cake.
Top with the second layer and gently press down to ensure the layers adhere. Spread the remaining heavy cream evenly over the top and sides of the cake. This step creates the signature buttery finish and prevents the cake from drying out.
Return the assembled cake to the oven and bake for an additional 15-20 minutes at 325°F (160°C). This final baking step helps the layers set and the cream to caramelize slightly, giving the cake its signature sheen and texture.
Finish and Serve
Remove the cake from the oven and let it cool completely on a wire rack. Once cooled, dust the top and sides generously with the 0.25 cup of powdered sugar. This step enhances the visual appeal and balances the rich flavors of the cake.
Slice the cake into 12 equal portions and serve at room temperature. The layers should be moist and tender, with a perfect balance of buttery crust and spiced plum filling. This cake is best enjoyed within 2-3 days for optimal texture and flavor.
Pro Tips For Making 1kg Plum Cake
- Cream Butter Properly: Beat the butter and sugar until it’s pale, almost fluffy—like a cloud you could float on. I used to stop when it looked “light,” but it needs to be almost translucent. This ensures the cake stays tender, not dense, especially with the weight of plums. (Yes, even if you’re impatient like me.)
- Poke the Plums: Cut a shallow cross in each plum before baking—it keeps them from bursting and makes them soften faster. I learned this the hard way when a batch of plums turned into a gooey mess mid-bake. Also, save the juices! Strain them and toss them into the batter for extra moisture.
- Don’t Overmix the Batter: Mix the wet and dry ingredients just until combined—lumps are fine. Overmixing develops gluten, and your cake will turn out tough instead of light. I used to beat it like I was punishing the bowl, but now I stop as soon as the flour disappears. (Your future self will thank you.)
- Bake in Stages: Start at 180°C (350°F) for 20 minutes, then drop to 160°C (320°F) for the rest. The high heat sets the structure, while the lower temp ensures even baking without a dry crust. I was skeptical until I tried it—now it’s non-negotiable for a 1kg cake. (Your oven’s hot spots will hate you less, too.)
Regional styles of this dish
German Plum Streusel
In Germany, plum cakes often feature a crisp streusel topping that contrasts beautifully with the soft cake layers. Replace the heavy cream with a streusel mix of 1 cup all-purpose flour, ½ cup brown sugar, ½ cup cold butter, and 1 tsp cinnamon.
Sprinkle this over the assembled cake before the final bake—it adds texture and a caramelized crunch. 🌟
French Plum Clafoutis
French bakers transform plum cake into clafoutis, a custard-based dessert. Replace the cake layers with a batter of 4 eggs, 1 cup milk, ½ cup sugar, and ½ cup flour, then pour it over steamed plums in a baking dish.
Bake at 350°F for 35-40 minutes until golden. Serve warm with vanilla ice cream.
Scandinavian Cardamom Twist
Nordic bakers emphasize cardamom in plum cakes, often adding 1 tsp extra ground cardamom to the batter. Swap the nutmeg for allspice and fold in ½ cup chopped almonds into the crust. The result is a nutty, aromatic cake with a crunchy base—perfect with whipped cream. ❄️
British Plum Loaf
Traditional British plum loaf skips layers entirely, baking the cake and plums together in a loaf pan. Mix 1 cup chopped plums into the batter before baking at 325°F for 50-60 minutes.
Top with a sugar glaze of ½ cup powdered sugar and 1 tbsp lemon juice for a glossy finish.
Italian Plum Panettone
For a festive twist, blend plum cake with panettone flavors. Add ½ cup raisins and 1 tsp orange zest to the batter, then bake in a tube pan at 325°F for 45 minutes.
Serve with a dusting of powdered sugar and a sprinkle of candied citrus peel for a holiday-worthy dessert.
American Spiced Rum Version
Southern bakers often infuse plum cakes with spiced rum. Replace the vanilla extract with 1 tbsp dark rum and add ½ tsp cloves** to the spice mix.
The rum enhances the plum flavor and adds warmth—ideal for a cozy autumn dessert. Pair with a scoop of bourbon ice cream for extra decadence. 🍹

Frequently asked questions
Can I use canned plums instead of fresh?
Fresh plums are ideal for their natural juiciness, but you can use canned plums in a pinch. Drain them well and pat dry to remove excess moisture, which prevents a soggy cake. For best results, simmer the canned plums with the spices for 10 minutes to intensify their flavor before layering.
How do I adjust this recipe for a smaller cake?
For a 6-inch cake (about 500g), halve all ingredients and bake in a single layer. Reduce the plum filling to 1.5 lbs and bake the layers for 20-25 minutes each. The final assembly time remains the same. Always use the same oven temperature for consistency.
Why did my cake turn out dense?
Overmixing the batter or using warm butter are common culprits. Keep the butter cold and mix just until combined—stop when no dry flour remains. Also, ensure your baking powder is fresh (test by mixing with water; it should bubble). If the plums were too wet, drain them thoroughly before layering.
Can I make this cake gluten-free?
Yes! Replace the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob’s Red Mill). Add ½ tsp xanthan gum to improve texture. For the crust, use a gluten-free flour mix with 1 tbsp cornstarch. Note that gluten-free cakes may be slightly denser but still delicious.
How do I store leftovers?
Wrap the cake tightly in plastic wrap and store at room temperature for 3-4 days. For longer storage, freeze individual slices wrapped in parchment and plastic for up to 3 months. To reheat, warm at 300°F for 10 minutes to restore the buttery aroma.
