Desserts
This apple and plum upside-down cake delivers a caramelized fruit crown that transforms ordinary dessert into a showstopper. The secret lies in baking the fruit first—halved apples and plums nestle into a buttery cake batter, creating golden, jammy layers beneath a tender, spiced crumb.
I perfected this technique after years of testing, ensuring the fruit stays juicy while the cake emerges perfectly moist, never dry.
The upside-down method isn’t just about presentation—it’s about flavor. As the fruit caramelizes, its natural sugars meld with the cake’s warm spices (cinnamon, nutmeg), creating a harmonious balance between sweet and tart.
A 350°F oven does the work while you prep, and the entire process takes just 60 minutes—including the 40 minutes of baking time that lets the fruit release its juices into the cake.
What you’ll end up with is a cake that’s impossible to resist: a golden fruit crown that peels away to reveal layers of spiced cake beneath, each bite offering a mix of tender fruit and moist crumb.
Serve it warm with a scoop of vanilla ice cream or a dollop of whipped cream for the ultimate dessert experience. The contrast of warm cake and cold ice cream is pure magic.
For extra texture, toast chopped pecans or walnuts and sprinkle them over the fruit before baking. Or, if you prefer a bolder spice profile, add a pinch of cardamom to the cake batter.
This recipe scales beautifully—double the batter for a crowd, or halve it for a single-serving skillet cake. The possibilities are endless, but the result is always delicious.
Ingredients for apple and plum upside down cake
Golden fruit crown meets spiced moist cake layers—just these ingredients transform dessert night.
| Ingredient | Amount | Notes |
|---|---|---|
| Apples (Granny Smith or Honeycrisp) 🍎 | 4 medium | Halved, cores removed |
| Plums (Italian or Purple) 🍑 | 4 medium | Pitted, halved |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Unsalted Butter 🧈 | 1 cup | Room temperature, full-fat |
| Large Eggs 🥚 | 3 whole | Room temperature |
| Vanilla Extract 🌿 | 1 tbsp | Pure extract preferred |
| Ground Cinnamon 🌶️ | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌶️ | ½ tsp | Freshly grated |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Pecans or Walnuts 🥜 | ½ cup | Toasted, chopped |
| Baking Powder 🍞 | 2 tsp | Aluminum-free preferred |
| Brown Sugar 🍚 | ¼ cup | Packed, for fruit caramel |
The fruit makes or breaks this cake. Granny Smith or Honeycrisp apples stay firm while baking, while Italian plums add that perfect jammy sweetness. Grab the freshest you can find—bruised spots turn mushy. I always check the produce section at Whole Foods for the best variety, but the regular grocery store works too. For the nuts, pecans have a buttery flavor that pairs perfectly, but walnuts add a nice crunch if that's what you've got. Toast them in a dry pan for 3-4 minutes until fragrant—don't skip this, it's worth the extra minute.
No Granny Smith apples? Fuji or Gala work too, though they're slightly softer. Plums can be swapped for peaches or nectarines if needed. Running low on brown sugar? White sugar plus 1 tsp molasses mimics the flavor. The butter needs to be room temperature—stick it in the microwave for 40 seconds if it's cold. For the spices, Penzeys has the best ground cinnamon and nutmeg, but the regular grocery store stuff works fine. If you want to get fancy, add a pinch of cardamom to the batter for a Middle Eastern twist—trust me on this.
This cake reheats beautifully—just pop a slice in the oven at 300°F for 5-10 minutes to restore that warm, gooey fruit center. Store leftovers wrapped tightly at room temperature for 2 days, or in the fridge for 5 days. The fruit caramel keeps best when the cake is at room temperature, so take it out 30 minutes before serving. I always make a double batch—one for dinner, one for breakfast the next morning with a dollop of whipped cream. The flavors actually get better as it sits overnight.
Why You'll Love This Recipe
- No-Fuss Fruit Prep: The fruit just sits in the pan—no peeling, no coring, no fuss. Slice those Granny Smiths and plums thick enough to hold their shape, and you’re done. (Yes, even if you’re mid-conversation with someone.)
- Sweet-Tart Magic: That first bite? Crisp caramelized edges from the sugar, then the bright tang of Honeycrisp apples and juicy plums cutting through the buttery cake. It’s like summer in a slice—no overpowering sweetness, just perfect balance.
- Weeknight or Celebration: Make it for a lazy Sunday brunch or pull it out for a dinner party—no one will guess it’s this easy. The upside-down magic means you can serve it warm or at room temp, and it still looks impressive. (Between us, I’ve served it to in-laws cold from the fridge.)
- Leftovers? Best Part: This cake actually improves overnight. The fruit soaks up more of the cake’s moisture, making every second slice even better. And honestly? It’s cheap to make—just fruit you’d buy anyway, plus pantry staples. Win-win.
Step-by-step instructions for apple and plum upside down cake
Here's how to create a showstopping cake with caramelized fruit on top and perfectly moist layers below.
Prepare the Fruit Topping
Preheat your oven to 350°F and position a rack in the lower third. In a small bowl, toss the 4 medium Apples (Granny Smith or Honeycrisp) and 4 medium Plums (Italian or Purple) with 0.25 cup Brown Sugar until evenly coated. Arrange the fruit halves cut-side up in a greased 9-inch round cake pan, packing them snugly but not overlapping.
Here's the thing—don't skip the sugar coating. This creates that beautiful caramelized crown when baked. I like to arrange the fruit in a circular pattern with the apples forming the outer ring and plums in the center for visual appeal. The fruit should fit tightly to prevent the cake batter from seeping underneath.
Create the Caramel Base
In a small saucepan, combine 1 cup Unsalted Butter, 1.5 cups Granulated Sugar, and 0.5 cup Pecans or Walnuts. Cook over medium heat for 3-4 minutes, stirring constantly, until the butter melts and the mixture turns golden brown. This is your flavor foundation.
Watch carefully as it cooks—you want it to bubble gently but not burn. The nuts will toast slightly, adding wonderful depth to the cake. Pour this caramel mixture evenly over the fruit in the prepared pan, pressing down gently to help it settle. This step ensures your fruit stays in place and gets that perfect caramel glaze.
Mix the Cake Batter
In a large mixing bowl, cream together the 1 cup Unsalted Butter (room temperature) and 0.5 cup Brown Sugar until light and fluffy, about 2-3 minutes. Add the 3 whole Large Eggs one at a time, beating well after each addition. Mix in the 1 tbsp Vanilla Extract until fully combined.
In a separate bowl, whisk together the 2.5 cups All-Purpose Flour, 2 tsp Ground Cinnamon, 0.5 tsp Ground Nutmeg, 0.5 tsp Salt, and 2 tsp Baking Powder. Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined. Don't overmix—you should still see some flour streaks.
Bake to Golden Perfection
Pour the batter over the fruit and caramel mixture in the prepared pan, spreading it evenly. Bake for 50-60 minutes or until a toothpick inserted in the center comes out clean. The cake is done when the top is golden brown and springs back when gently touched.
I know it seems like a long time, but patience pays off here. The cake needs time to set properly with that beautiful fruit crown on top. If the edges brown too quickly, tent the pan with aluminum foil to prevent over-browning while allowing the center to cook through.
Invert and Serve
Let the cake cool in the pan for 10 minutes, then carefully invert it onto a serving plate. Run a thin knife around the edges to loosen it if needed. Let it cool completely before slicing—this makes it easier to flip and serves the cake properly.
Here's a pro tip: I like to dust the cooled cake with a light layer of powdered sugar just before serving. This highlights the beautiful caramelized fruit and adds a touch of elegance. The contrast between the warm spiced cake and the cool fruit topping makes every bite special. Serve with a dollop of whipped cream or vanilla ice cream for the ultimate experience.
Pro Tips For Making Apple And Plum Upside Down Cake
- Core the Plums First: I learned this the hard way—waiting until after baking to remove pits is a mess. Use a small spoon or melon baller to scoop out the pits and a little flesh from each plum before arranging them in the pan. This keeps your cake from looking like a fruit bomb went off mid-bake.
- Preheat Pan and Oven Together: Cold pans steal heat, and this cake’s caramelized bottom depends on even cooking. Place your 9-inch cast-iron or oven-safe skillet in the preheating oven for 5–10 minutes while you prep the fruit. The pan’s warmth helps the butter melt faster and creates that perfect sticky crust from the get-go.
- Slice Apples Thin and Toss: Thick apple slices turn mushy, and that’s no good in an upside-down cake. Cut Granny Smiths into ¼-inch slices, then toss them with a teaspoon of sugar and a pinch of cinnamon—this keeps them firm and adds just enough sweetness to balance the plums. Spread them evenly in the pan so no one slice gets overcooked.
- Skip the Extra Egg Wash: The cake batter already has enough moisture to create a tender crumb and a golden top. Brushing extra egg wash on the batter before baking makes the cake dense and gummy. Just bake it at 350°F (175°C) for the full 45–50 minutes, and the natural sugars will caramelize beautifully without help.
Storing and reheating this dish
Room Temp Storage
This cake tastes best at room temperature, so store leftovers in an airtight container for up to 2 days. The fruit caramel stays gooey and delicious when kept away from fridge cold.
I always take it out 30 minutes before serving to let the flavors bloom—trust me, that warm fruit center is worth the wait. 🌟
Fridge Preservation
For longer storage, refrigerate wrapped tightly for up to 5 days. The cake will keep its moisture but might need 5-10 minutes at 300°F to restore that warm, gooey center.
I like to slice it before refrigerating so it reheats more evenly—just pop individual portions in the oven until heated through.
Freezing Techniques
Freeze slices wrapped individually in plastic wrap for up to 3 months. Thaw overnight in the fridge, then warm in the oven at 300°F for 10-12 minutes for that perfect texture.
The fruit stays juicy when frozen properly—just avoid ice crystals by using airtight containers. I double-wrap slices with foil first for extra protection.
Reheating Methods
For individual servings, microwave for 20-30 seconds on medium power—just enough to warm through without drying. For best results, I prefer the oven method: 300°F for 5-10 minutes until the fruit center is soft and gooey again. The oven method preserves the cake's structure better than microwave reheating.
Serving Warm
Serve warm slices straight from the oven with a scoop of vanilla ice cream or whipped cream. The contrast of warm cake and cold topping is pure magic. For extra flair, dust with powdered sugar right before serving—it makes the caramelized fruit look even more stunning.
I often make a double batch so we can enjoy it warm one night and cold the next. ✨

Frequently asked questions about apple and plum upside down cake
Can I use other fruits instead of apples and plums?
This cake works beautifully with peaches, nectarines, or even pears—just adjust the baking time slightly since softer fruits cook faster. For tartness, try sour cherries or blackberries (halved), but reduce the sugar in the fruit coating to 2 tablespoons to balance flavors.
Why does my cake come out dry?
Overbaking or using too much flour are the usual culprits. Stick to the 50-60 minute baking time and check with a toothpick—it should come out with moist crumbs, not dry. For extra moisture, add 2 tablespoons sour cream or Greek yogurt to the batter. Also, ensure your oven isn't running hot by testing with an oven thermometer.
How do I make this cake gluten-free?
Replace the 2.5 cups all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill) plus 1 teaspoon xanthan gum. For best results, also swap the baking powder for a gluten-free version. The cake will still be moist but may have a slightly denser texture. Test with a small batch first!
Can I bake this in a different pan shape?
Yes! Use a 9-inch square pan for a different presentation, but reduce baking time to 40-45 minutes (check at 35 minutes). For individual servings, try 6-ounce ramekins—bake for 25-30 minutes at 350°F. Just adjust the fruit quantity proportionally (e.g., 1 apple half + 1 plum half per ramekin).
What’s the secret to perfect caramelized fruit?
The sugar coating is key! Toss the fruit with brown sugar (not white) for deeper caramelization. Use firm fruits like Granny Smith apples that hold their shape. For extra shine, brush the baked fruit with apricot jam warmed with 1 teaspoon lemon juice before inverting. The acidity helps set the glaze beautifully.
