This upside-down style plum cake is the kind of simple bake that feels special without being fussy: fluffy vanilla-like crumb on top, jammy plums underneath, and a thin caramel layer from brown sugar. It’s a great everyday dessert for late summer when plums are abundant, and it slices neatly for lunchboxes or coffee breaks. If you like quick fruit cakes, you might also enjoy this fast apple and dark chocolate cake for another easy treat. Nutrition-wise, this is a traditional sweet cake—best enjoyed as a treat, especially since it includes a full cup of sugar.
Why This Recipe Is Helpful
- Uses basic pantry ingredients plus fresh plums—no butter to soften, no mixer required (though a whisk helps).
- The plums bake into a soft, saucy layer so the cake stays moist for days.
- Ground ginger adds a gentle warmth that makes the fruit taste brighter.
Best For
Anyone who wants a reliable, homey fruit cake for coffee time, potlucks, or a simple family dessert.
Be Careful If
This recipe is fairly high in sugar and includes gluten (flour) and dairy (yogurt), so it may not suit everyone’s needs.
Ingredients
- 3 large eggs
- 1 cup + 1 tablespoon (200 g) granulated sugar
- 5 tablespoons (100 g) plain yogurt (full-fat or low-fat)
- 1/2 cup (120 ml) vegetable oil (neutral, like sunflower or canola)
- 1 2/3 cups (250 g) all-purpose flour
- 2 teaspoons (10 g) baking powder
- 1 tablespoon (12–15 g) brown sugar
- 1.1 lb (500 g) plums, pitted and sliced into wedges
- 1/2 teaspoon ground ginger
- Optional for the pan: a little oil or baking spray (if not using parchment)
Ingredient Notes
- Plums: Slightly firm plums hold their shape best; very ripe plums will be softer and juicier (still delicious, just more jammy).
- Yogurt: Plain yogurt adds tenderness; Greek yogurt works too, but loosen it with 1–2 teaspoons water if very thick.
- Oil: Keeps the crumb moist longer than butter-based cakes.
- Ginger: Subtle but important; you can reduce to 1/4 teaspoon if you prefer it very mild.
Kitchen Tools Needed
- 8–9 inch (20–23 cm) cake pan or similar baking dish
- Mixing bowl
- Whisk (or hand mixer)
- Spatula
- Measuring cups/spoons or kitchen scale
- Knife and cutting board
Step-by-Step Instructions
- Preheat and prep the pan. Heat the oven to 360°F (180°C). Lightly grease your baking dish, or line the bottom with parchment for easier unmolding.
- Make the plum base. Sprinkle the brown sugar evenly over the bottom of the dish.
- Arrange the fruit. Pit and slice the plums, then arrange them over the brown sugar, cut side up and fairly snug (they’ll shrink as they bake).
- Season the fruit. Sprinkle the ground ginger evenly over the plums.
- Whip eggs and sugar. In a mixing bowl, beat the eggs and granulated sugar for 3–4 minutes until the mixture looks paler, thicker, and slightly fluffy. (This helps the cake rise and stay light.)
- Add wet ingredients. Whisk in the yogurt and vegetable oil until smooth.
- Add dry ingredients carefully. Add the flour and baking powder. Mix just until you no longer see dry flour. Stop as soon as the batter is combined—over-mixing can make the cake tight.
- Pour and level. Pour the batter over the plums and gently spread it to the edges so the fruit is fully covered.
- Bake. Bake for about 55 minutes, or until the top is golden and a toothpick inserted into the cake (not through a plum pocket) comes out clean or with a few moist crumbs.
- Cool before serving. Let the cake cool in the pan for 15–20 minutes so the plum layer settles. If you want to flip it, run a knife around the edge and invert onto a plate while still warm (parchment makes this easier).
Pro Tips
- Beat the eggs and sugar until thickened—this small step really helps the cake feel lighter.
- If your plums are very juicy, keep them in larger wedges (not thin slices) so the base doesn’t turn watery.
- Check doneness in a spot that’s mostly cake; fruit juices can make a toothpick look “wet” even when baked.
- Let it cool a bit before slicing so the plum layer doesn’t slide out.
Lighter Swaps
- Use low-fat yogurt instead of full-fat.
- Reduce the granulated sugar to 3/4 cup (150 g) for a less-sweet cake (it will be slightly less tender and less golden, but still good).
- Use 2/3 whole-wheat flour + 1/3 all-purpose for a slightly heartier crumb.
Common Mistakes
- Over-mixing after adding flour, which can make the cake dense.
- Using an unprepared pan, leading to sticking—at minimum, grease well; parchment is even better.
- Cutting too soon, which can make slices messy and cause the fruit layer to run.
Serving Suggestions
Serve slightly warm with plain yogurt or a small scoop of vanilla ice cream, or enjoy it at room temperature with tea or coffee.
Storage Instructions
Store covered at room temperature for 1 day, then refrigerate for up to 4 days. The cake stays moist thanks to the fruit and oil.
Reheating Tips
Warm individual slices for 10–15 seconds in the microwave, just until the plum layer loosens and smells fragrant.

Frequently Asked Questions
Can I use other fruit instead of plums?
Yes. Nectarines, apricots, or sliced peaches work well in a similar amount. Very juicy berries can make the base wetter, so expect a softer set.
Do I have to flip it upside down?
No. You can serve it straight from the pan as a “plum-bottom” cake. Flipping is optional—it’s mostly for presentation.
Why did my cake sink a little in the middle?
A slight dip can happen from the fruit layer and steam. Make sure it’s fully baked (test in a cake-only spot) and avoid over-mixing the batter.
Conclusion
This plum cake is a simple, cozy bake with big payoff: tender crumb, jammy fruit, and a hint of warm spice. It’s an easy way to use up seasonal plums and still have a dessert that feels like something you’d proudly set out for guests.
