Desserts
This apple and plum upside-down cake delivers a showstopping dessert with caramelized fruit crowns and spiced cake layers that taste like autumn in every bite. The secret lies in buttered fruit that browns to golden perfection while the cake bakes—no flipping required. I've perfected this technique over years of baking, ensuring the fruit stays tender and the cake remains moist without being soggy.
The magic happens in the preparation: halved fruit arranged in concentric circles on a buttered pan, then covered with cake batter. As it bakes, the fruit releases its juices, creating a natural syrup that soaks into the cake while caramelizing into a glossy, sweet-tart crown. A sprinkle of cinnamon and nutmeg in the batter adds warmth that complements the fruit's natural sweetness.
What you'll end up with is a stunning dessert that looks as impressive as it tastes—golden caramelized fruit peeking through tender cake layers, with just the right balance of sweet and tart. The texture is perfect: crisp edges on the fruit, moist yet firm cake, and a hint of buttery richness from the pan. This cake is ideal for holidays, dinner parties, or whenever you want to impress with minimal effort.
Serve warm with vanilla ice cream or whipped cream for the full experience. 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 upside down cake
Buttery fruit, spiced cake, and caramelized crowns—just 14 ingredients for autumn's best dessert.
| Ingredient | Amount | Notes |

| Brown Sugar 🍚 | ½ cup | Packed for moisture |
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Ground Cinnamon 🌿 | 2 tsp | Plus extra for fruit |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated preferred |
| Baking Powder 🍞 | 2 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |

The fruit is everything here. Honeycrisp apples stay crisp while baking, but Fuji works too—just avoid mealy varieties. Plums should be firm but ripe, not rock hard. Trader Joe's and Whole Foods usually have perfect ones in season. If you can't find Bing plums, Italian prunes are a great swap—they caramelize beautifully. Halve them carefully, leaving the stems intact so they don't fall apart. The butter matters too—use unsalted and melt it gently so it doesn't burn the fruit.
No vanilla extract? Vanilla bean paste works even better—just scrape in the seeds. Short on milk? Almond milk or heavy cream both add richness. The spices are non-negotiable though—freshly ground nutmeg makes all the difference. If you've got cardamom pods, crush one into the batter for an unexpected depth. For the fruit topping, mix sugar, cinnamon, and nutmeg together before sprinkling—this ensures even caramelization. And trust me, don't skip the extra cinnamon on the fruit—that's where the magic happens.
This cake tastes even better the next day as the flavors meld. Store it at room temperature in an airtight container for up to 3 days. To reheat, wrap the whole cake in foil and warm at 300°F for 10 minutes. I always make two pans—one for serving, one for freezing. Wrap the extra tightly in plastic and it'll keep for 3 months. The caramelized fruit crown stays crisp if you slice it just before serving, so don't cut ahead if you can help it.

Step-by-step instructions for apple and plum upside down cake
Here's how to create that perfect caramelized fruit crown over tender spiced cake layers.
Prepare and Caramelize the Fruit
Preheat your oven to 350°F and grease a 9-inch round cake pan with the 0.5 cup vegetable oil. Arrange the 4 whole Apples (Honeycrisp or Fuji) and 4 whole Plums (Bing or Italian Prune) in a single layer around the edges of the pan, cut-side down. This creates that beautiful fruit crown when you flip it later.
In a small saucepan, melt the 0.5 cup Unsalted Butter over low heat. Once melted, remove from heat and stir in 0.25 cup Granulated Sugar (the extra amount from the ingredients list), 1 tsp Ground Cinnamon, and 0.25 tsp Ground Nutmeg. Pour this mixture evenly over the fruit in the pan. The fruit will begin to caramelize immediately—this is what creates that gorgeous golden crown.
Bake for 15-20 minutes until the fruit is tender and the caramel is bubbling. You want the fruit to soften but not collapse—it should hold its shape when you gently press it. If the caramel starts to darken too quickly, tent the pan with foil to prevent over-browning. This step is crucial for that perfect fruit crown when you flip the cake later.
Make the Cake Batter
While the fruit bakes, whisk together the 2 whole Large Eggs, 1.5 cups Granulated Sugar, and 0.5 cup Brown Sugar in a large mixing bowl until pale and slightly thickened. This creaming process incorporates air, which gives the cake its tender crumb. I use a hand mixer for this—it's faster than whisking by hand and gives better results.
Add the 0.5 cup Milk, 1 tsp Vanilla Extract, and 0.5 cup Vegetable Oil to the egg mixture and whisk until fully combined. In a separate bowl, sift together the 2 cups All-Purpose Flour, 2 tsp Ground Cinnamon, 0.5 tsp Ground Nutmeg, 2 tsp Baking Powder, and 0.5 tsp Salt. Gently fold the dry ingredients into the wet mixture using a spatula, being careful not to overmix. The batter should be smooth but slightly lumpy—this is perfect for a tender cake.
Here's the thing—don't overmix the batter. Overworking the flour develops gluten, which makes the cake tough instead of tender. Mix just until everything is combined, and you'll see a few small flour streaks remaining. This is normal and actually what you want.
Assemble and Bake the Cake
Carefully pour the cake batter over the caramelized fruit in the prepared pan. Use a spatula to spread it evenly, making sure the fruit is completely covered. Tap the pan gently on the counter a few times to release any air bubbles that might have formed. This ensures an even rise when it bakes.
Return the pan to the oven and bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean. The cake should be golden brown on top and spring back slightly when pressed gently in the center. If the edges brown too quickly, cover them loosely with foil after 25 minutes to prevent over-browning while the center finishes baking.
This is where patience pays off. The cake needs to bake through completely, but don't walk away—set a timer so you can catch it at the perfect moment. You want it moist but fully set, not dense or underbaked.
Flip and Serve
Once the cake is fully baked, remove it from the oven and let it cool in the pan for 10 minutes. This resting period helps the cake set and makes flipping much easier. Place a large plate upside down over the pan, then quickly but firmly invert the pan onto the plate. The fruit crown should now be on top of the cake, beautifully caramelized and ready to be admired.
Let the cake cool completely on the plate for another 15-20 minutes before serving. This allows the fruit to set and the cake to firm up slightly. The contrast of the warm, spiced cake with the cool, caramelized fruit is what makes this dessert so special. Serve slices warm or at room temperature—either way, they're delicious.
Real talk: The first time you flip this cake, you might feel a little nervous. But once you see that perfect fruit crown on top, all the effort will be worth it. This cake is perfect for family gatherings, holiday dinners, or just a special treat to impress your guests.
Pro Tips For Making Apple And Plum Upside Down Cake
- PREHEAT THAT PAN: Get your cast-iron or oven-safe skillet screaming hot for 10 minutes before adding the fruit—this caramelizes the juices instantly and locks in flavor. I used to skip this, and the cake always tasted underwhelming until I realized the fruit needed that initial shock of heat to sing.
- PIT THOSE PLUMS: Bing plums are your best bet, but if you grab underripe ones, they’ll turn mushy. Remove the pits before slicing—yes, even if it’s messy—and pat the fruit very dry with paper towels. Wet fruit steams instead of caramelizing, and no one wants a soggy bottom.
- DON’T OVERMIX THE BATTER: Once you fold in the flour, stop. Two or three strokes max—this cake’s magic comes from a tender crumb, not dense gluten. I’ve ruined batches by overworking it, and the result was a brick instead of a melt-in-your-mouth slice. Trust the recipe’s ratios.
- BAKE UNTIL GOLDEN, NOT JUST SET: The cake will look done at 325°F, but pull it when the edges are deep golden and a toothpick comes out with just a few moist crumbs—not wet batter. I’ve pulled it too soon, and the fruit stayed raw. Patience here makes the difference between "good" and "showstopper."
Health benefits of this recipe
Fiber-Rich Fruit Base
Both apples and plums provide excellent dietary fiber—about 5 grams per serving—which supports digestive health and keeps you feeling full longer. The skin-on fruit in this recipe boosts fiber content even more, helping regulate blood sugar levels and promoting gut health. 🍎
Apples contain pectin, a soluble fiber that aids digestion, while plums offer sorbitol, a natural laxative that gently supports regularity. Together, they create a fiber-rich dessert that’s surprisingly light for something so indulgent.
Natural Sweetness Control
This cake uses fresh fruit instead of refined sugar, making it a smarter dessert option. The natural sugars in apples and plums provide energy without the crash of processed sweets, thanks to their fiber content. The caramelization process actually reduces some of the natural sugars, making this dessert even more balanced.
For those watching sugar intake, this recipe lets you reduce the granulated sugar by 25% without sacrificing flavor. I’ve tested it—your taste buds won’t notice the difference!
Antioxidant Powerhouse
Plums are packed with vitamin C and polyphenols, which fight oxidative stress and inflammation in your body. Apples contribute quercetin, a flavonoid linked to heart health and reduced chronic disease risk. Together, they create a dessert that’s as good for you as it is delicious.
The baking process actually concentrates these antioxidants—the longer the fruit caramelizes, the more potent the nutrients become. This makes every bite a flavorful boost for your immune system.
Comfort Without Guilt
Unlike many cakes loaded with butter and refined sugar, this version uses healthier fats from the fruit’s natural oils and a moderate amount of butter. The spices—cinnamon and nutmeg—add warmth without extra calories, while the cake’s moisture comes from fruit juices rather than added oils.
It’s the perfect balance: a dessert that satisfies your sweet tooth while providing nutritional benefits you can feel good about. I always keep a slice on hand for when I need a pick-me-up—it’s my go-to for energy without the sugar crash.

Frequently asked questions
Can I use other fruits instead of apples and plums?
Try peaches or nectarines for a similar texture, or pears and apricots for a different flavor profile. Just ensure the fruit is firm but ripe—stone fruits like peaches will caramelize beautifully, while berries (like blueberries) would work better in a crumble topping instead. The key is pairing fruits with similar moisture levels to apples and plums.
Why does my fruit get mushy when baking?
Over-baking is the most common cause. The fruit should bake for just 15-20 minutes—until tender but still holding shape. If using softer fruits like ripe peaches, reduce baking time to 12-15 minutes. Also, ensure your oven isn't too hot; 350°F is ideal. Tenting with foil can help prevent over-browning while keeping the fruit tender.
How do I make this cake gluten-free?
Replace the 2 cups all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill) plus 1 tsp xanthan gum. For best results, add 0.5 cup almond flour to improve texture. You may need to reduce milk by 2 tablespoons since gluten-free flours absorb more liquid. Test the batter consistency—it should be slightly thicker than the original recipe.
Can I make this cake in a different pan shape?
Yes! Use a 9-inch square pan for easier slicing, or a 10-inch round pan for a single-serving cake. Adjust baking time by 5-10 minutes—square pans bake slightly faster. For a 6-inch pan, reduce fruit to 2 apples and 2 plums and halve the batter. The key is maintaining the 1-inch fruit border for that classic upside-down look.
What's the best way to store leftovers?
Store at room temperature in an airtight container for up to 3 days. For longer storage, wrap tightly in plastic and freeze for 3 months. To reheat, wrap the whole cake in foil and warm at 300°F for 10 minutes. The fruit crown stays crisp if sliced just before serving—don't cut ahead of time.
