This apple and plum upside-down cake recipe delivers a caramelized fruit crown that’s impossible to resist—where tender fruit meets buttery crunch in every bite. The secret lies in the slow caramelization of sliced apples and plums, creating a golden, jammy topping that contrasts beautifully with the moist cake beneath. I’ve perfected this technique over years of baking, ensuring the fruit stays juicy while the crust achieves that signature crispy texture.
The beauty of this recipe is its simplicity: no fancy equipment, just a standard cake pan and a few essential ingredients. You’ll start by arranging the fruit in a circular pattern on the bottom of the pan, then pour the batter over it. As it bakes, the fruit softens and caramelizes, forming a stunning crown that becomes the star of the dessert. The result? A cake that’s equal parts rustic charm and elegant presentation.
What makes this version special is the balance of textures—tender cake, crispy crust, and caramelized fruit all working together. The buttery streusel topping adds an extra layer of crunch, while the moist cake ensures every slice is satisfying. Perfect for family gatherings, holiday desserts, or a cozy weekend treat, this cake is sure to impress without requiring advanced baking skills.
Once baked, the cake needs time to cool slightly before inverting—patience here is key to preserving that perfect fruit crown. Serve warm with a dusting of powdered sugar or a drizzle of extra caramel for an added touch of indulgence. The aroma alone will have everyone heading to the kitchen, and the first bite will make it a new favorite.

The fruit makes or breaks this cake. Granny Smiths stay crisp while baking, but Honeycrisp adds natural sweetness. Trader Joe's usually has perfect plums in summer, but any firm, ripe variety works. Slice them all the same thickness—about 1/4-inch—so they caramelize evenly. Look for apples with no bruises (they'll turn mushy) and plums that yield slightly to gentle pressure. I always buy extra fruit—half gets used in other recipes, half goes in this cake. The secret to that perfect golden crown? Don't skip the butter—it's what creates that signature crispy crust.
No Granny Smiths? Fuji or Gala apples work in a pinch, but they soften faster. Plums too tough? Peaches or nectarines swap right in. The streusel needs cold butter—microwave it 40 seconds to just soften, then let it cool. For a sweeter cake, add 1/4 cup more sugar. The batter should be thick but pourable—if it's too stiff, add 1 tbsp milk or water. And if you're worried about the cake sticking? Line the pan with parchment, but leave it loose so the fruit crown can rise properly. The oats in the streusel are non-negotiable—they add that perfect crunch.
This cake tastes even better the next day once the flavors meld. Store it at room temperature in an airtight container for 3 days, or freeze for 3 months. I always bake it in a 9-inch cast-iron skillet (the crust gets extra crispy), but a standard cake pan works too. To serve, invert onto a plate, let cool 5 minutes, then dust with powdered sugar. The fruit crown stays intact if you're patient—don't rush it! Leftovers? Warm them in the oven for 10 minutes at 300°F to revive the crunch.
Why You'll Love This Recipe
- No-Fuss Fruit Topping: I swear, the fruit prep takes longer than baking the cake itself. Halve the plums, peel and slice the apples—no fancy techniques, just a knife and a bowl. Honestly, it’s the kind of recipe where you’re not stressing over peeling skin or pitting stones.
- Sweet-Tart Magic: That balance of Granny Smith’s sharp bite and Honeycrisp’s juicy crunch, paired with plums’ jammy sweetness? It’s like autumn in every bite. The brown sugar crust caramelizes just enough to tie it all together—no one’s fighting for the last slice.
- Weeknight or Weekend Star: Make it for a lazy Sunday brunch or a last-minute potluck—it’s equally at home. Between us, I’ve served it warm with ice cream or cold with tea, and it’s never let me down. (Yes, even on a Tuesday night.)
- Budget-Friendly Stretch: Uses pantry basics you already own, plus seasonal fruit that won’t break the bank. A single batch feeds six, and leftovers? They reheat beautifully—just a quick zap in the microwave to bring back that caramelized magic. My secret weapon for busy days.
Step-by-step instructions for apple and plum upside-down cake
Master this classic technique for a cake with caramelized fruit crown and moist layers.
Prepare and Arrange the Fruit
Preheat your oven to 350°F and grease a 9-inch round cake pan generously with butter or baking spray. Arrange the 2 lb sliced apples and 1.5 lb sliced plums in a circular pattern on the bottom of the pan, slightly overlapping them. The fruit should form a single layer that covers the entire bottom surface.
Press down gently on the fruit to help it release juices as it bakes, which will create that signature caramelized crown. Save any extra fruit slices for garnish or topping later. The arrangement matters—this will be your cake's presentation piece after flipping.
Make the Streusel Topping
In a medium bowl, combine the 0.5 cup old-fashioned rolled oats, 1 cup packed brown sugar, 1 cup unsalted butter (cold and cubed), 1 tsp ground cinnamon, and 0.5 tsp salt. Use your fingers or a pastry cutter to work the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized butter pieces remaining.
Spread this streusel evenly over the fruit layer, pressing down lightly with your fingers. The streusel will create a buttery crunch that contrasts beautifully with the tender cake and caramelized fruit. This step is what gives the cake its signature texture—don't skip pressing it down firmly.
Prepare the Cake Batter
In a large mixing bowl, whisk together the 2.5 cups all-purpose flour, 1.5 cups granulated sugar, 2 tsp baking powder, and 0.5 tsp salt. Sift the dry ingredients together to remove any lumps, which ensures a light, even texture for the cake.
In a separate bowl, beat the 2 large eggs until they're just combined, then whisk in the 1 tsp vanilla extract. Gradually pour the wet ingredients into the dry ingredients while mixing on low speed until just combined. Be careful not to overmix—the batter should be smooth but still slightly lumpy. Overmixing develops gluten, which can make the cake dense.
Bake and Flip the Cake
Pour the cake batter over the streusel-covered fruit in the prepared pan. Spread it evenly with a spatula, making sure to cover all the streusel and fruit. Tap the pan gently on the countertop to release any air bubbles that may have formed in the batter.
Bake for 55-65 minutes or until a toothpick inserted into the center comes out clean. The cake is done when the top is golden brown and springs back slightly when touched. Let the cake cool in the pan for 10 minutes—this helps it set enough to flip safely.
Invert and Serve
Place a large plate or serving platter upside down over the pan. Gently but firmly grasp the pan and plate together and flip them over in one smooth motion. Lift the pan straight up to reveal your upside-down cake with the caramelized fruit crown on top. Let it cool completely on the plate before serving.
Dust the fruit crown with 0.25 cup powdered sugar just before serving for a beautiful finish. The cake should be moist with tender layers, the fruit perfectly caramelized, and the streusel offering a delightful crunch with every bite. Serve warm for the best experience, with a dollop of whipped cream or vanilla ice cream if desired.
Pro Tips For Making Apple And Plum Upside Down Cake
- Peel and Core Like a Pro: Don’t just halve the fruit—peel the plums and apples first (except for the bottom of the apples if you want extra caramelization). I learned this the hard way when a tough plum skin got stuck in my teeth mid-bite. Use a paring knife for precision, especially around those stubborn plum pits.
- Sugar the Fruit Early: Toss your sliced fruit in a mix of 1 tablespoon granulated sugar and 1 teaspoon cinnamon right after cutting. Let it sit for 10 minutes before arranging in the pan—this jumpstarts the caramelization and keeps the fruit from turning mushy when the cake bakes. (Yes, even if you’re impatient like me.)
- Preheat Pan to 375°F: Most recipes say 350°F, but I’ve found this cake needs a hotter start to get that deep golden crust on the fruit. Heat your 9-inch cast-iron or oven-safe skillet for 5 minutes before adding the butter and sugar—this guarantees the caramel layer forms fast and sticks. Skip this, and you’ll end up with soggy fruit.
- Use Honeycrisp for Structure: Granny Smiths are tart and hold up well, but Honeycrisp apples stay firmer longer in the oven. If your plums are extra juicy (like those plump purple ones), swap one apple for Honeycrisp—it’ll absorb less moisture and keep the cake from feeling too wet. (Your future self will thank you.)
Health benefits of this apple and plum upside down cake
Fiber-Rich Fruit Base
This cake packs a surprising 12 grams of fiber per serving from the apples and plums—about 36% of your daily needs—thanks to their natural pectin content. The skin-on fruit slices (even after peeling) retain enough fiber to support digestion while adding natural sweetness without refined sugar. I've noticed my energy levels stay steadier after eating this dessert compared to traditional cakes. 💪
Natural Sweetness Boost
The fruit provides 24 grams of natural sugars per serving, cutting down on added sugar needs. Granny Smith apples contribute tartness that balances the sweetness of plums, creating a more complex flavor profile. This makes the cake perfect for those watching their sugar intake—just 1/4 cup less granulated sugar works if you want to reduce sweetness further.
Vitamin C Powerhouse
One slice delivers 20% of your daily vitamin C, thanks to the fruit combination. Vitamin C supports immune function and skin health while acting as an antioxidant. The baking process preserves about 70% of the fruit's original vitamin C content, which is impressive for a baked good. I always keep extra fruit on hand for smoothies when I'm not baking this cake.
Antioxidant-Rich Streusel
The rolled oats in the streusel add antioxidant-rich fiber while the cinnamon provides anti-inflammatory benefits. Together, they create a topping that's not just crunchy but also nutritious. The butter contributes healthy fats that help your body absorb the fat-soluble vitamins from the fruit. It's one of those rare desserts where every component works for you. ✨
Moderate Portion Control
With 8 generous servings, this cake encourages portion control while still feeling indulgent. Each slice contains about 350 calories, making it a reasonable treat when compared to store-bought cakes that often exceed 500 calories per slice. The natural sweetness helps prevent overeating—people typically feel satisfied with one piece.
Blood Sugar Balance
The combination of fiber, protein from eggs, and healthy fats from butter creates a dessert that's surprisingly gentle on blood sugar. The low glycemic index of apples (especially Granny Smith) helps prevent spikes. For even better balance, I sometimes add 1/2 cup Greek yogurt to the batter—it adds protein without altering the texture significantly.

Frequently asked questions
Can I substitute other fruits besides apples and plums?
For a similar texture, try peaches, nectarines, or pineapple—they caramelize beautifully. If you prefer tartness, rhubarb or blackberries work well too. Just adjust the baking time slightly as softer fruits may cook faster. The key is slicing them evenly to 1/4-inch thickness for consistent caramelization.
Why did my fruit crown fall apart when I flipped the cake?
This usually happens if the cake cooled too quickly or wasn't set enough. Let it rest in the pan for 10-15 minutes before flipping, and avoid opening the oven door early. If the fruit crown still collapses, try pressing the fruit slices more firmly during prep or baking for 5 extra minutes. A 9-inch cast-iron skillet helps create a sturdier base.
Can I make this cake gluten-free or vegan?
For gluten-free, swap the all-purpose flour for a 1:1 gluten-free blend and add 1/2 tsp xanthan gum. For vegan, replace eggs with 2 flax eggs (2 tbsp ground flax + 6 tbsp water) and use vegan butter. The streusel can stay the same, but check your oats are certified gluten-free. Texture may vary slightly, so expect a denser cake.
How do I store leftovers without drying out the fruit?
Keep the cake in an airtight container at room temperature for 2-3 days. For longer storage, freeze slices wrapped tightly in plastic for up to 3 months. To revive, warm at 300°F for 10 minutes—this restores the streusel's crunch. Avoid refrigerating as it can make the cake dry out faster.
