This apple and plum upside-down cake delivers a caramelized fruit top that transforms into a golden crust while keeping the vanilla layers moist and tender. The secret lies in the fruit preparation—slicing apples and plums evenly ensures they cook through without turning mushy, while a touch of cinnamon and brown sugar creates that signature sweet, spiced aroma. I’ve perfected this recipe over years of baking, and the key is patience: letting the fruit caramelize slowly in the oven before flipping reveals a stunning presentation that tastes just as good as it looks.
The cake’s structure makes it foolproof for home bakers. A simple vanilla batter with a hint of almond extract complements the fruit’s natural sweetness, while the caramelized layer adds depth without overpowering. Whether you’re serving it warm with vanilla ice cream or at room temperature with a dusting of powdered sugar, the contrast between the crispy fruit top and velvety cake is what makes this dessert unforgettable. The best part? It’s versatile—swap in pears or cherries if apples and plums aren’t in season, or adjust the sugar for a lighter version.
What sets this upside-down cake apart is the textural magic—the fruit’s juices soak into the cake as it bakes, creating a moist crumb that stays fresh for days. The caramelized layer isn’t just decorative; it’s the star, offering a balance of sweet and tangy flavors with every bite. For a restaurant-quality finish, brush the caramelized fruit with a little melted butter after flipping to enhance the golden hue and add richness. This cake is perfect for holidays, brunch gatherings, or even a simple dessert night in.
Ready to impress? The process is straightforward: arrange the fruit in a buttered pan, pour the batter over it, and bake until the top is golden and the fruit is tender. Flipping is the dramatic moment—just slide the cake onto a plate with confidence, and you’ll have a showstopper that tastes as good as it looks. Let’s get baking!
Ingredients for apple and plum upside down cake
Eight ingredients create this showstopper dessert with caramelized fruit and moist vanilla layers.
| Ingredient | Amount | Notes |
|---|---|---|
| Granny Smith Apples 🍎 | 4 medium | Peeled, sliced into 1/4-inch pieces |
| Plums 🍑 | 4 medium | Pitted, sliced into 1/4-inch pieces |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |

The fruit is where the magic happens. Granny Smith apples bring tartness to balance the sweet plums—Bosc or Santa Rosa plums work best for their firm texture. I always grab mine from Whole Foods or the local farmers market in summer, but grocery store produce works too. Slice them evenly (about 1/4-inch thick) so they cook through without turning to mush. The secret? Tossing them with brown sugar and cinnamon before baking intensifies that signature caramelized flavor. Pro tip: Pat them dry with a paper towel first—they caramelize better when they're not soggy.
No Granny Smiths? Fuji or Honeycrisp apples add sweetness but still hold their shape. Plums unavailable? Pears or peaches work in a pinch, though they soften faster. The butter matters here—unsalted works best since you're adding salt separately. Short on almond extract? Skip it, but know it adds that subtle marzipan-like depth. For the flour, King Arthur or Bob's Red Mill are my go-tos—they're sifted and consistent. And if you're worried about the cake being too sweet, reduce the granulated sugar to 1 cup and add 1/2 cup more flour instead.
This cake tastes even better the next day, so bake it ahead if you can. Store it in an airtight container at room temperature for up to 3 days, or freeze the whole cake (unfrosted) for 2 months. To reheat, wrap it in foil and warm at 300°F for 10 minutes—the fruit top gets crispy again. I always make a double batch because it disappears fast. Dust with powdered sugar right before serving—it adds that final touch of elegance. And trust me, the first slice is always the best, so save the pretty picture for last.

Step-by-step instructions for apple and plum upside down cake
Here's how to create a perfectly caramelized fruit top with a moist vanilla cake that'll impress everyone.
Prepare the Fruit Mixture
Preheat your oven to 350°F. In a medium bowl, combine the 4 medium Granny Smith Apples and 4 medium Plums, both sliced into ¼-inch pieces. Toss them with ¼ cup of the granulated sugar and ½ cup of the brown sugar until evenly coated. This sugar coating is what creates that gorgeous caramelized crust on top.
Next, melt the 1 cup Unsalted Butter in a small saucepan over low heat. Once melted, remove from heat and stir in 1 teaspoon of the vanilla extract and ½ teaspoon of the almond extract (if using). Pour this butter mixture over the fruit and toss gently to coat. Let it sit for 5 minutes while you prepare the cake batter.
Mix the Cake Batter
In a large mixing bowl, whisk together the 2.5 cups All-Purpose Flour, 2 teaspoons Baking Powder, 2 teaspoons Ground Cinnamon, and ½ teaspoon Salt. Sift this mixture directly into the bowl to avoid lumps—this ensures a light, tender cake texture. Make a well in the center and add the remaining 1.5 cups Granulated Sugar.
Add the 2 whole Large Eggs (at room temperature) to the well and mix gently with a rubber spatula. Then, pour in the remaining 1 teaspoon Vanilla Extract and mix until just combined. Be careful not to overmix—you want a few lumps to remain for a tender crumb. The batter should be thick but pourable.
Assemble and Bake
Lightly grease a 9-inch round cake pan and line the bottom with parchment paper. Arrange the fruit mixture in a single layer in the bottom of the pan, pressing down gently to create an even surface. This layer will caramelize beautifully during baking and become your delicious topping.
Pour the cake batter over the fruit, spreading it evenly with a spatula. Tap the pan gently on the counter to release any air bubbles. Bake in the preheated oven for 50-55 minutes, or until a toothpick inserted into the center comes out clean. The top should be golden brown, and the cake should spring back when gently pressed.
Flip and Finish
Once the cake is done, remove it from the oven and let it cool in the pan for 10 minutes. Then, place a large plate or serving dish over the pan and carefully flip the entire pan upside down. The fruit should now be on top, caramelized and beautiful. Tap the pan gently to release the cake onto the plate.
Use a pastry brush to lightly brush the fruit with any remaining pan juices for extra moisture. Dust the top with the ¼ cup Powdered Sugar while the cake is still warm. Serve warm or at room temperature for the best texture and flavor experience.
Pro Tips For Making Apple And Plum Upside Down Cake
- USE COLD FRUIT CUTS: Slice your Granny Smith apples and plums just before arranging them in the pan—no need to pre-cut hours ahead. The fruit releases more juice when cold, caramelizing faster and sticking better to the bottom. (I learned this after watching my first batch turn into a soggy mess.)
- BROWN THE SUGAR FIRST: Toss that granulated sugar with a splash of water and brown it in the pan for 3-4 minutes before adding fruit. The deeper caramel color and nutty flavor cut through the tartness of the apples and plums, making the whole cake taste richer. (Yes, it’s an extra step—but it’s worth it.)
- DON’T OVERFILL THE PAN: Pack the fruit tightly, but leave room for the batter to rise—no more than ¾ of the way up the sides. Overstuffing leads to a dense, gummy cake that won’t flip properly. Trust me, I’ve tried the "just one more plum" approach.
- SKIP THE BUTTERFINGER BATTER: Whisk your batter until just combined, then fold in the melted butter with a spatula—don’t pulse it in a food processor. Overmixing develops gluten, turning your cake into a tough, dry brick instead of a tender, fluffy upside-down masterpiece. (Your future self will thank you.)
Essential equipment for this recipe
Must-Have Baking Pans
Start with a 9-inch round cake pan—this size ensures even baking and the perfect flip. I recommend a non-stick pan like Wilton's Perfect Results or a carbon steel pan for that classic caramelized crust. If you don’t have non-stick, lightly grease with butter or baking spray and line the bottom with parchment paper to prevent sticking. The pan should have sloped sides for easy flipping, not straight walls. 🔥
Precision Tools for Fruit Prep
Use a sharp chef’s knife or mandoline slicer for even fruit slices—¼-inch thickness is key. I love the OXO Good Grips mandoline for consistent cuts. A fine-mesh sieve helps drain excess fruit juices if you pat them dry before baking. For tossing the fruit, a medium mixing bowl with a rubber spatula works best to coat evenly with sugar and butter.
Mixing Essentials
A stand mixer with the paddle attachment simplifies batter mixing, but a hand mixer or even a whisk works if you’re gentle. Sift your dry ingredients through a fine-mesh sifter to avoid lumps—King Arthur’s sifter is my go-to. For measuring, use a digital kitchen scale for accuracy, especially with flour and sugar. A liquid measuring cup ensures precise butter and milk measurements.
Flipping with Confidence
Flip day requires a large, sturdy serving plate—I use a ceramic platter (like Le Creuset’s stoneware) for stability. A parchment paper square under the pan prevents sticking. For the dramatic reveal, practice the flip over a towel-lined counter first. A pastry brush (like West Bend’s silicone brush) helps spread any pan juices over the fruit after flipping for extra shine.
Optional Pro Upgrades
For restaurant-quality results, invest in an oven thermometer to ensure your oven hits 350°F accurately. A cake tester (or clean toothpick) checks doneness perfectly. For presentation, a dusting brush (like Ateco’s powder brush) makes powdered sugar application effortless. And if you’re ambitious, a cake stand elevates the final dish for serving. ✨

Frequently asked questions
Can I use other fruits instead of apples and plums?
Try peaches, pears, or cherries for a similar texture. The key is using firm, juicy fruits that hold their shape when baked. For softer fruits like peaches, reduce baking time by 5-10 minutes to prevent over-cooking. Just ensure all fruit is sliced evenly to ¼-inch thickness for consistent caramelization.
Why did my cake stick to the pan?
This usually happens when the pan isn't properly greased or lacks parchment paper. Always use butter or baking spray on the sides and bottom, then line the bottom with parchment. For extra insurance, chill the pan in the fridge for 10 minutes before baking—this helps the fruit layer set better and reduces sticking.
How do I make this gluten-free?
Replace the 2.5 cups all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill or King Arthur). Add ½ teaspoon xanthan gum to improve texture. Keep all other ingredients the same, but expect a slightly denser crumb. Test with a toothpick—gluten-free cakes may need 2-3 extra minutes in the oven.
Can I bake this cake in a different-sized pan?
Yes, but adjust baking time accordingly. For an 8-inch pan, reduce time by 10-15 minutes (watch closely at 40 minutes). For a 10-inch pan, increase by 10-15 minutes. The fruit layer should be golden and tender, not mushy. Always check with a toothpick—it should come out clean or with a few moist crumbs.
What's the best way to store leftover cake?
Keep it in an airtight container at room temperature for up to 3 days. For longer storage, freeze the whole cake (unfrosted) for 2 months. To reheat, wrap in foil and warm at 300°F for 10 minutes—this restores the fruit's crispy texture. The cake actually tastes better the next day as flavors meld!
