Apple And Plum Upside Down Cake Recipe: Caramelized Fruit Crown and Spiced Crunch

This apple and plum upside-down cake delivers a caramelized fruit crown that makes every slice look like a work of art. 🌟 The secret lies in arranging the fruit perfectly in a buttered pan, letting their natural sugars melt into a glossy, spiced glaze while the cake beneath stays moist and tender. I've perfected this recipe over years of baking, balancing sweetness and acidity to create a dessert that feels both nostalgic and refined.

The magic happens in the oven, where the fruit softens into a sticky, spiced caramel while the cake rises just enough to hold its shape. Traditional techniques like buttering the pan and using a simple cake batter ensure the fruit stays in place, creating that iconic upside-down presentation. This isn't just dessert—it's a showstopper that transforms ordinary fruit into something extraordinary.

What you'll end up with is a warm, spiced cake topped with a crown of caramelized apples and plums, their juices pooling into a syrupy glaze. The texture is perfect—crisp edges on the fruit, a tender crumb in the cake, and just the right amount of moisture to keep everything luscious. Serve it warm with a dollop of whipped cream or a dusting of powdered sugar for that final touch of elegance.

Whether you're baking for a special occasion or simply craving comfort, this recipe delivers restaurant-quality results with minimal effort. The best part? It's versatile enough to work with gluten-free flour or vegan butter if needed, so everyone at the table can enjoy it. Let's get baking!

Ingredients for apple and plum upside down cake

Eight simple ingredients transform into a stunning upside-down cake with caramelized fruit crown.

The fruit is everything here. Farmers market apples and plums have the best flavor, but grocery store varieties like Honeycrisp apples and Santa Rosa plums work perfectly. Look for firm fruit—soft spots turn mushy when baked. I always slice the apples into 1/4-inch rounds and halve the plums lengthwise. Costco or Trader Joe's usually have great organic options if you want to splurge. Pro tip: Toss the fruit with the extra 2 tbsp sugar and 1 tsp cinnamon before arranging—this jumpstarts the caramelization.

No vanilla extract? Almond extract at half the amount works in a pinch. Short on apples? Swap in pears or pineapple chunks—just reduce baking time by 5 minutes. The brown sugar can be swapped for white sugar, but you'll lose that deep caramel flavor. For a gluten-free version, use a 1:1 gluten-free flour blend. The cake batter is forgiving—if it's slightly lumpy, don't stress. The fruit arrangement is where the magic happens, so take your time placing those slices in a perfect circle.

This cake tastes even better the next day once the fruit has fully caramelized. Store it in an airtight container at room temperature for up to 3 days. For longer storage, wrap tightly in plastic and refrigerate for 1 week. To reheat, warm slices at 300°F for 5-10 minutes—this revives that warm, gooey fruit topping. I always bake an extra pan because it disappears faster than you'd think.

Step-by-step instructions for apple and plum upside down cake

Here's how to create that stunning caramelized fruit crown and perfectly spiced cake.

Preheat your oven to 350°F. Grease a 9-inch round cake pan with the 0.25 cup vegetable oil, then sprinkle evenly with 2 tablespoons granulated white sugar (from the extra amount in your ingredients). This creates that beautiful caramelized crust we're after.

In a bowl, toss the 4 medium apples and 4 medium plums (sliced as directed) with 1 tablespoon granulated white sugar and 1 teaspoon ground cinnamon. Arrange the fruit in a single layer in the prepared pan, pressing down gently so they fit snugly. The fruit should cover the bottom completely—this is your cake's future crown!

In a large mixing bowl, cream together the 0.75 cup unsalted butter and 1.5 cups granulated white sugar until light and fluffy—about 3-4 minutes with an electric mixer. This step is crucial for that tender cake texture. Scrape down the sides of the bowl occasionally to ensure even mixing.

Add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 1 teaspoon vanilla extract. In a separate bowl, whisk together the 2 cups all-purpose flour, 2 teaspoons baking powder, 1.5 teaspoons ground cinnamon, 0.5 teaspoon ground nutmeg, and 0.5 teaspoon salt. Gently fold the dry ingredients into the wet mixture just until combined—don't overmix or your cake will be tough.

Pour the batter over the arranged fruit in the prepared pan, spreading it evenly to the edges. Tap the pan gently on the counter to release any air bubbles. Bake for 45-50 minutes or until a toothpick inserted in the center comes out clean and the top is golden brown.

Here's the thing—don't open the oven during baking. The fruit releases moisture that helps create that perfect caramelized crust. When the cake is done, let it cool in the pan for 10 minutes before carefully inverting it onto a serving plate. The dramatic fruit crown will reveal itself as the cake cools completely.

Once the cake has cooled completely (about 1 hour total), dust the fruit crown with an additional 1 teaspoon ground cinnamon for extra warmth. Serve warm or at room temperature with a scoop of vanilla ice cream or a dollop of whipped cream for that classic upside-down cake experience.

This cake tastes even better the next day as the flavors meld together. Store leftovers covered at room temperature for up to 3 days or refrigerate for up to 5 days. The fruit will keep its beautiful caramelization and the cake will stay moist.

Dietary considerations for these flavors

Gluten-Free Adaptation

For a gluten-free version, replace the 2 cups all-purpose flour with a 1:1 gluten-free flour blend like King Arthur Measure for Measure or Bob's Red Mill 1-to-1. These blends mimic the texture of regular flour while maintaining the cake's tender crumb. I’ve tested this substitution and found that adding 1 extra teaspoon of xanthan gum helps bind the batter, preventing a crumbly texture. 🌾

When measuring gluten-free flour, spoon it into your measuring cups and level off—don’t scoop directly from the bag, as it’s lighter than all-purpose flour. For extra moisture, reduce the baking time by 3-5 minutes to prevent over-browning. The fruit caramelization remains just as stunning!

Vegan Butter Option

To make this cake vegan, swap the unsalted butter for Earth Balance vegan butter or Miyoko’s Creamery cultured vegan butter. These brands melt and brown beautifully, just like dairy butter. For the pan preparation, use coconut oil instead—it has a neutral flavor and high smoke point. 🧈

Vegan butter works best when softened to room temperature before creaming with sugar. If your batter seems too thick, add 1 tablespoon of plant-based milk (like almond or oat) to improve texture. The cake will still rise properly, and the fruit caramelization won’t be affected!

Nut-Free Considerations

This recipe is naturally nut-free, but always double-check your ingredients—especially the vanilla extract and spices. Brands like McCormick and Pure Extracts offer nut-free certified vanilla. For extra safety, use a separate whisk and measuring spoons when handling spices to avoid cross-contamination. 🌿

If you’re serving this cake to guests with severe nut allergies, consider labeling it clearly. The all-purpose flour and baking powder in this recipe are typically processed in nut-free facilities, but always verify packaging for allergen warnings.

Lower Sugar Options

To reduce sugar, replace half of the granulated white sugar with coconut sugar or monk fruit sweetener. Coconut sugar caramelizes similarly to white sugar but has a deeper molasses flavor. For monk fruit, use a 1:1 ratio—it’s zero-calorie and won’t affect the cake’s texture. 🍚

The fruit will still caramelize, though the crust may be slightly less glossy. To compensate, brush the fruit with 1 tablespoon of apple cider before baking—this adds natural sweetness and enhances browning. The cake will taste just as delicious with 25% less sugar!
