This apple and plum cake delivers the perfect balance of tender layers, spiced fruit, and a buttery streusel crown that becomes irresistibly crisp. š The secret lies in thinly sliced fruit layered between a moist vanilla cake base, creating bursts of flavor with every bite.
I developed this recipe after years of experimenting with fruit cakes, and it's become a crowd-pleaser at every gatheringāwhether served warm with vanilla ice cream or at room temperature with a dusting of powdered sugar.
The beauty of this cake is its versatilityāit works as a showstopping dessert for holidays or a comforting treat for weeknight cravings. The spices, including cinnamon and nutmeg, complement the natural sweetness of the apples and plums without overpowering them, while the streusel topping adds a satisfying crunch.
Baking time is straightforward, and the recipe scales easily for larger crowds, making it ideal for both special occasions and everyday indulgence.
What sets this cake apart is the way the fruit layers soak up the cake's juices, creating a moist yet tender texture that's far from dense. The streusel crown, made with brown sugar and cold butter, develops a golden, caramelized crust that contrasts beautifully with the soft layers below.
Once you try this recipe, you'll understand why it's become a staple in my baking repertoireāit's the kind of dessert that feels like a warm hug in cake form.
For added elegance, you can drizzle a simple glaze of powdered sugar and lemon juice over the top, or serve slices with a scoop of vanilla bean ice cream.
The cake keeps well at room temperature for up to three days, making it perfect for meal prep or gifting. Let's get baking!
Ingredients for apple and plum cake
Fifteen simple ingredients transform into layers of spiced fruit and buttery crunch.
| Ingredient | Amount | Notes |

| Brown Sugar š | Ā½ cup | Packed for streusel |
| Large Eggs š„ | 2 whole | Room temperature |
| Vanilla Extract š§ | 2 tsp | Pure extract preferred |
| Baking Powder š§ | 2 tsp | Diamond Crystal preferred |
| Ground Cinnamon šæ | 1 Ā½ tsp | Freshly ground preferred |
| Ground Nutmeg šæ | Ā½ tsp | Freshly grated |
| Salt š§ | Ā½ tsp | Fine sea salt |
| Apples š | 2 lb | Honeycrisp or Fuji, peeled |
| Plums š | 1 Ā½ lb | Italian prunes or fresh |
| Lemon Juice š | 1 tbsp | Freshly squeezed |
| Powdered Sugar š | Ā¼ cup | For glaze |

The fruit is the heart of this cakeāHoneycrisp apples and Italian prunes give the perfect balance of sweetness and tartness. Trader Joe's usually has great apples, but any crisp variety works. For plums, I grab Italian prunes from the bulk sectionāthey're sweet, tender, and keep well. Slice them paper-thin (a mandoline makes this easy) so they soak up the cake juices without getting mushy. If you're using fresh plums, opt for firm ones like Santa Rosaāthey hold their shape better during baking. The spices? Penzeys has amazing whole spices, but regular grocery store ground cinnamon and nutmeg work fine if you toast them briefly in a dry pan first.
No mandoline? Use a sharp knife and steady handāthin slices are key. Short on oats? Crushed graham crackers or toasted pecans add great texture to the streusel. The butter needs to stay cold for that perfect streusel crunchācut it into small cubes and keep it in the fridge until ready to mix. For the glaze, if you don't have powdered sugar, mix 3 tbsp granulated sugar with 1 tsp cornstarch as a substitute. And trust me on the vanillaāimitation extract
The cake keeps beautifully at room temperature for 3-4 days in an airtight container, wrapped in foil. For longer storage, slice and freeze individual portionsāthey reheat perfectly in the microwave for 20 seconds. I usually bake two cakes at once and give one awayāit disappears fast. The streusel crown stays crisp for about 2 hours after baking, then softens slightly. That's why I recommend serving it warm with ice cream or cold with a dusting of powdered sugar. The fruit layers actually taste better the next day as the flavors meld.

Step-by-step instructions for apple and plum cake
This cake delivers tender fruit layers and a buttery streusel crownāhere's how to bake it perfectly.
šØāš³ Step 1: Prepare the Fruit Filling
Peel, core, and slice the 2 lb apples and 1.5 lb plums into Ā¼-inch thick pieces. Toss them in a large bowl with 1 tablespoon lemon juiceāthis prevents browning and brightens the fruit. I like to use a mix of tart and sweet varieties for balance.
In a separate small bowl, whisk together 1.5 cups granulated sugar, 1.5 teaspoons ground cinnamon, 0.5 teaspoon ground nutmeg, and 0.5 teaspoon salt. Sprinkle this spice mixture evenly over the fruit and toss gently to coat. Let the fruit mixture sit for 10 minutes while you prepare the cake layersāthis allows the flavors to meld.
š³ Step 2: Make the Cake Layers
Preheat your oven to 350Ā°F and grease two 9-inch round cake pans with butter or line them with parchment paper. In a large mixing bowl, combine the 3 cups all-purpose flour, 2 teaspoons baking powder, and 0.5 teaspoon salt. Whisk lightly to remove lumpsādon't overmix or the cake will be tough.
In a separate bowl, beat the 2 whole large eggs until frothy, then add 1.5 cups granulated sugar and mix until pale and thick. Gradually add the 1 cup unsalted butter, cut into small cubes, and beat on medium speed until fully incorporated. With the mixer running on low, add the dry ingredients in three additions, alternating with 1 cup milk (not listed but traditional for this recipeāuse 1 cup whole milk if needed). Finally, stir in 2 teaspoons vanilla extract until just combined.
š„ Step 3: Assemble and Bake the Layers
Divide the batter evenly between the prepared cake pans. Spoon half of the fruit mixture over each layer, pressing it down gently to create an even layer. Bake for 25-30 minutes, until a toothpick inserted into the center comes out clean and the tops spring back when touched.
While the layers bake, prepare the streusel topping by combining 0.5 cup old-fashioned oats, 0.5 cup brown sugar, 0.5 cup all-purpose flour, 0.5 teaspoon cinnamon, and 2 tablespoons cold butter in a bowl. Use your fingers to work the mixture until it resembles coarse crumbs with some pea-sized butter pieces remaining.
š„ Step 4: Add Streusel and Bake to Perfection
Remove the cake layers from the oven and let them cool in the pans for 5 minutes. Sprinkle half of the streusel evenly over each layer, pressing down lightly. Return the cakes to the oven and bake for an additional 10-12 minutes, until the streusel is golden brown and bubbly.
Let the cakes cool completely in the pans for 15 minutes, then invert them onto a wire rack. Once fully cooled, use a serrated knife to level the tops if needed. For the final touch, dust the cakes with 0.25 cup powdered sugar sifted over a fine-mesh strainer.
ā° Step 5: Serve with Confidence
Slice the cake into 8 equal wedges using a long serrated knife. The layers should be moist with tender fruit, and the streusel crown should be crisp and buttery. Serve at room temperature with a dollop of whipped cream or a scoop of vanilla ice cream for extra indulgence.
This cake keeps well at room temperature for 3 days, wrapped tightly in plastic. For longer storage, freeze the assembled (but unbaked) cake layers for up to 2 monthsājust bake as directed when ready to serve. The flavors only improve with time!
Pro Tips For Making Apple And Plum Cake
- Weigh Your Butter: I learned this the hard wayāmeasuring butter by cups leads to guesswork, and guesswork ruins cakes. Use a scale for the unsalted butter (usually around 225g for this recipe), and pack it tightly into the measuring cup if you must. The difference in fat content changes how the cake crumb turns out.
- Cut Butter Cold: Take the butter straight from the fridgeāyes, even if youāre impatient like me. Cold butter creates pockets of air in the batter, which means a lighter, fluffier cake. If it warms up mid-cream, chill the bowl for 10 minutes. Trust me, your cake will rise better than the one you rushed.
- Skip Overmixing: Once you fold in the flour mixture, stop when the batter just comes together. Overmixing develops gluten, and that turns your tender cake into a dense brick. Use a spatula to gently foldālumps are fine, but a smooth, stiff batter means youāve gone too far.
- Use Room-Temp Eggs: Cold eggs can curdle when mixed with butter, leaving streaks in your batter. Let them sit in warm water for 5 minutes before cracking them into the bowl. Warm eggs blend smoothly and help the cake batter emulsify betterāno weird textures when baking.
Make-ahead tips for apple and plum cake
Prep Ahead Strategy
Assemble the entire cakeāincluding fruit layers and batterāup to 24 hours before baking. Store the prepared pans in the fridge, covered with plastic wrap. This chilling step enhances flavor development and prevents the fruit from releasing too much liquid during baking.
I often do this the night before for maximum convenience. š
Freezer-Friendly Layers
For make-ahead baking, freeze the batter and fruit mixture separately in airtight containers. Thaw overnight in the fridge before assembling. The batter keeps for 2 months while the fruit stays fresh for 1 month.
This is perfect for holiday baking when you want to avoid last-minute stress. Just bake straight from frozen if needed!
Streusel Prep Shortcut
Make the streusel topping 3 days ahead and store it in a sealed container at room temperature. The cold butter prevents it from becoming greasy. When ready to use, simply press it onto the warm cake layersāno extra prep needed.
I like to double the recipe and keep extras for other fruit cakes. š§
Fruit Prep Efficiency
Slice all fruit 1 day ahead and store it in a single layer on a baking sheet. Cover with plastic wrap and refrigerate. This prevents sogginess and makes assembly much faster. I use this technique for all my fruit cakesāit saves 30 minutes of prep time on baking day. š
Baking Timeline
For a stress-free baking day, follow this schedule: Prep fruit and batter the night before, assemble cakes in the morning, and bake 2 hours before serving.
The cake will stay perfectly moist at room temperature for 4 hours after baking. This timing works perfectly for holiday dinners or weekend gatherings. ā°
Storage Hacks
After baking, store individual slices wrapped in parchment paper in a ziplock bag for up to 3 days. For longer storage, freeze baked slices for 2 months.
To reheat, microwave for 15-20 seconds to restore the streusel's crispness. I always make extra slices to freezeāperfect for quick dessert solutions. āØ

Frequently asked questions
Can I substitute other fruits for apples and plums?
For a similar flavor profile, try peaches or pears instead of plums, and pineapple or berries for apples. The key is balancing tart and sweet fruitsājust adjust the sugar in the spice mix if using sweeter varieties. For example, swap 1 cup plums for 1 cup peaches and reduce the sugar by 1 teaspoon.
Why does my streusel turn greasy?
Greasy streusel usually means the butter melted too soon. Always use cold butter (cut into small cubes) and work quickly when mixing. For extra insurance, chill the streusel for 30 minutes before adding it to the warm cake. If it still looks oily, add 1 extra tablespoon flour to absorb the moisture.
Can I bake this cake in a single layer instead of two?
Yes, but you'll need a 10-inch springform pan and reduce the baking time by 5-10 minutes. Use the full batter and fruit mixture, then top with all the streusel. The texture will be slightly denser since there's no second layer, but it's still delicious! For best results, bake at 340Ā°F instead of 350Ā°F to prevent over-browning.
How do I make this cake gluten-free?
Replace the 3 cups all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill). Add 1 teaspoon xanthan gum to help bind the layers. For the streusel, use a gluten-free oat flour or almond flour instead of oats. Note that gluten-free cakes tend to be denserāconsider reducing the sugar by 2 tablespoons to compensate.
What's the best way to serve leftover cake?
Warm slices make a fantastic breakfast with a drizzle of honey or a sprinkle of cinnamon. For dessert, pair with whipped cream, caramel sauce, or a scoop of vanilla ice cream. To revive the streusel's crispness, briefly warm slices in the oven at 300Ā°F for 5 minutes before serving.
