Upside Down Plum Cake: A Taste of Late Summer

The memory is etched in my mind: the scent of plums simmering on the stove, mingling with warm butter and sugar. My grandmother, her hands dusted with flour, would hum softly as she arranged the fruit in the bottom of her cast-iron skillet. This Upside Down Plum Cake wasn’t just a dessert; it was a symbol of late summer, of family gathered together, and of the simple joys in life. The way the caramelized plums would burst with flavor, soaking the tender cake with their sweet juice – it was pure magic. Every bite was a comforting reminder of home, and a tradition I’m delighted to share.

Ingredients

Topping:

2 tablespoons butter, melted
2 tablespoons brown sugar
½ teaspoon fresh lime juice
4 Italian plums, not peeled, each cut into 6 wedges (use more if you like plums!)

Batter:

1 ⅔ cups all-purpose flour, sifted
¾ teaspoon baking soda
½ teaspoon baking powder
¼ teaspoon salt
1 pinch grated nutmeg
½ teaspoon ground cinnamon
½ cup butter, softened
1 cup sugar
2 eggs
¾ cup milk

Equipment Needed

10″ springform cake pan
Mixing bowls
Sifter
Electric mixer
Wire rack

Instructions

Preheat your oven to 350 degrees F (175 degrees C). Ensuring accurate oven temperature is crucial for even baking.
Pour the melted butter into a 10″ springform cake pan. The springform pan is essential for easy release of the delicate cake after baking.
Swirl the butter around to totally cover the inside surfaces of the pan. This creates a non-stick barrier and helps the cake release cleanly.
Sprinkle the brown sugar evenly on top of the buttered pan. The brown sugar will caramelize and create a beautiful, rich sauce.
Arrange the plum wedges in a single layer over the brown sugar, covering the base of the pan. Don’t be afraid to use more plums if you like a fruitier cake. The more plums, the more intense the flavor and moisture.
Drizzle the lime juice over the arranged plums. The lime juice adds a touch of brightness and acidity, balancing the sweetness of the plums and brown sugar.
Set the prepared pan aside while you make the batter.
In a medium bowl, sift together the all-purpose flour, baking soda, baking powder, salt, nutmeg, and cinnamon. Sifting ensures a light and airy cake. Set aside the dry ingredients.
In a large bowl, cream together the softened butter and sugar using an electric mixer until light and fluffy. This step is crucial for incorporating air into the batter and creating a tender crumb.
Add the eggs one at a time to the creamed mixture, beating well after each addition until smooth. This emulsifies the batter and prevents curdling.
Gradually add the dry ingredients and the milk to the creamed butter mixture, alternating between them. Begin and end with the dry ingredients. Add a third of the dry ingredients, then a third of the milk, beating in between additions until just combined. Repeat until all the dry ingredients and milk are used up. This ensures even distribution of ingredients and prevents overmixing.
Scrape down the sides of the bowl and beat the batter for 1 minute to ensure everything is well incorporated. This step helps to further develop the gluten and create a smooth batter.
Carefully pour the batter evenly over the plum wedges in the prepared cake pan. Spread the batter gently to avoid disturbing the plum arrangement.
Bake in the preheated oven for about 1 hour. Start checking for doneness at 50 minutes.
The cake is done when a toothpick inserted in the center comes out clean. If the top of the cake is browning too quickly, you can loosely tent it with foil during the last 15 minutes of baking.
Remove the cake from the oven and leave it in the pan to cool on a wire rack for 30 minutes. This allows the cake to settle and makes it easier to release from the pan.
After 30 minutes, carefully invert the cake onto a serving plate. Ensure the plate is larger than the cake pan to catch any excess caramel sauce.
Serve warm or at room temperature.

Expert Tips & Tricks

For an even deeper caramel flavor, use dark brown sugar instead of light brown sugar.
If you don’t have Italian plums, other stone fruits like peaches, nectarines, or apricots can be used. Adjust baking time as needed.
To prevent sticking, you can line the bottom of the springform pan with parchment paper before adding the butter and sugar.
If the cake is browning too quickly on top, loosely tent it with aluminum foil for the last 15-20 minutes of baking.
For a richer flavor, add a tablespoon of rum or brandy to the melted butter before pouring it into the pan.

Serving & Storage Suggestions

This Upside Down Plum Cake is best served warm or at room temperature, either on its own or with a dollop of whipped cream or a scoop of vanilla ice cream. It pairs beautifully with a cup of black coffee or a glass of dessert wine.

Leftovers can be stored in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 5 days. To reheat, warm individual slices in the microwave for a few seconds or in a preheated oven at 300°F (150°C) for about 10 minutes.

For longer storage, the cake can be frozen for up to 2 months. Wrap it tightly in plastic wrap and then foil before freezing. Thaw overnight in the refrigerator before serving.

FAQs (Frequently Asked Questions)

Q: Can I use frozen plums?
A: Yes, you can use frozen plums. Thaw them completely and drain any excess liquid before arranging them in the pan.

Q: Why is my cake soggy in the middle?
A: A soggy middle could be due to underbaking. Make sure to check for doneness with a toothpick and bake for a longer time if needed.

Q: Can I make this cake ahead of time?
A: Yes, you can bake the cake a day ahead of time. Store it at room temperature, tightly covered.

Q: What if I don’t have a springform pan?
A: While a springform pan is ideal, you can use a regular cake pan lined with parchment paper, leaving an overhang to help lift the cake out after baking.

Q: My caramel is too dark and bitter. What did I do wrong?
A: The brown sugar may have burned. Ensure your oven temperature is accurate and consider loosely tenting the cake with foil if the top is browning too quickly.
