Why Upside-Down Cake?

Upside-down cakes have charmed dessert lovers for generations. The classic technique involves layering fruit on the bottom of the pan, often with a sticky, sweet glaze, then covering with batter.

What Makes This Upside-Down Plum Cake Special?

• Fresh Seasonal Plums: The star of the show, offering a natural tang and juicy bite.
• Bright Citrus Notes: Orange juice and zest lift the natural sweetness of the fruit.
• Aromatic Ginger: Adds a gentle warmth that highlights the plums’ complexity.
• Lighter Batter: Incorporates yogurt and olive oil for a tender crumb and less saturated fat.
• Wholesome Cornmeal: Adds subtle nuttiness and provides an appealing texture.
• Balanced Sweetness: With just the right amount of sugar, this dessert is flavorful without being cloying.

Ingredients for the Upside-Down Plum Cake

For a standard 9-inch round cake:

• 1/2 cup orange juice (freshly squeezed works best)
• 1 tablespoon finely grated fresh ginger
• 1 cup granulated sugar, divided
• 6-8 ripe but firm plums, pitted and sliced into wedges (about 1 1/2 lb)
• 1 tablespoon orange zest (from one large orange)
• Olive oil (for greasing and batter)
• 1 cup all-purpose flour
• 1/2 cup medium or fine-ground cornmeal
• 1/2 teaspoon fine sea salt
• 2 teaspoons baking powder
• 1/2 teaspoon baking soda
• 3/4 cup low-fat plain yogurt (Greek or regular)
• 1/3 cup light olive oil (or neutral oil)
• 2 large eggs
• 1 teaspoon pure vanilla extract
• Optional: Additional yogurt or whipped cream for serving

Step-by-Step Directions

1. Prepare the Syrup & Fruit

• Heat oven to 350°F (177°C).
• In a large saucepan, combine the orange juice, grated ginger, and 1/4 cup of the sugar. Cook over low heat until the sugar fully dissolves, about 2–3 minutes.
• Increase heat to bring mixture to a low boil; then reduce to a simmer. Cook until syrupy and slightly reduced (another 2–3 minutes).
• Remove saucepan from heat. Add the plum wedges and orange zest, toss gently, and let cool while you prepare the cake pan and batter.

2. Prepare the Pan and Dry Ingredients

• Oil a 9-inch round cake pan. Line the bottom with parchment paper and oil the parchment as well for easy release.
• In a big mixing bowl, whisk together the flour, cornmeal, salt, baking powder, baking soda, and the remaining 3/4 cup sugar. This base gives rise, body, and a lovely crumb to the cake.

3. Wet Ingredients & Combining

• In a separate bowl, blend the yogurt, 1/3 cup olive oil, eggs, and vanilla extract. Whisk until fully combined and creamy.
• Pour the yogurt mixture into the dry ingredient bowl. Mix gently with a spatula until just incorporated; avoid overmixing to maintain a tender cake.

4. Arrange the Fruit and Finish Assembly

• Place the cooled plum wedges (rescued from their syrup) in concentric circles, starting at the center of the pan and working outward, overlapping slightly to cover the base.
• Spoon the reserved syrup from the saucepan evenly over the plums, infusing the fruit with extra flavor and sheen.
• Gently dollop the batter over the arranged fruit. Using an offset spatula or the back of a spoon, smooth the batter to fully cover the plums and reach the edges of the pan.

5. Bake & Unmold

• Transfer the pan to the preheated oven, baking for 65–70 minutes, or until the cake is golden, springs back slightly, and a wooden pick inserted in the center emerges clean.
• Let cake cool in the pan for 10 minutes. Slide a butter knife around the edges to loosen any stuck bits.
• In one confident motion, invert a serving platter over the cake pan, then flip both together to invert the cake onto the platter. Gently peel off the parchment paper to reveal the stunning plum mosaic.

6. Serve & Enjoy!

• Let cool for at least another 10–15 minutes.
• Slice and serve warm or at room temperature, dolloped with extra yogurt or a cloud of whipped cream if desired.

Nutritional Advantages

This cake is as health-conscious as it is beautiful. By using olive oil and yogurt, the recipe lowers saturated fat while maintaining a rich crumb. Plums deliver fiber, vitamin C, and antioxidants, while cornmeal provides an extra bump of complex carbs and micronutrients. Clocking in at just 377 calories per serving, it’s a satisfying treat you can savor without guilt.

Tips for Success

• Choose Ripe but Firm Plums: Too soft and they turn mushy; too hard and they’re tart. The Goldilocks zone—firm yet yielding—is perfect.
• Parchment Is Essential: This ensures a flawless release of the sticky fruit topping.
• Don’t Overbake: Check at the 65-minute mark; overbaked cake becomes dry.
• Layer That Fruit: Be generous and overlap slices. The plums shrink during baking.

Seasonal & Ingredient Variations

• Switch Up the Stone Fruit: Try peaches, nectarines, apricots, or even cherries in place of plums. Each brings its own summery character.
• Add Berries: Scatter a handful of blueberries or raspberries among the plums for pops of flavor and color.
• Spice it Up: A pinch of cardamom or cinnamon in the batter complements stone fruits beautifully.
• Gluten-Free Option: Substitute your favorite one-to-one gluten-free flour blend for best results. If using, increase yogurt slightly for added moisture.

Serving Suggestions

• At Brunch: This cake is a showstopper when served with coffee and fresh fruit on a sunny morning.
• As Dessert: Dress up slices with a dollop of tangy Greek yogurt, crème fraîche, or lightly-sweetened whipped cream.
• Ice Cream Pairing: Vanilla or honey ice cream is a luxurious (but highly recommended) finishing touch.
• Warmed or Cold: The cake is delicious at room temperature or slightly warmed through; leftovers make an excellent next-day treat.
