Ingredients
FOR THE TOPPING
Unsalted butter, for greasing pan
1 cup/220 grams packed light brown sugar
2 pounds plums, pitted and sliced into wedges (about 7 plums)
2 tablespoons lemon juice
FOR THE CAKE
1 ⅓ cups/260 grams granulated sugar
4 large eggs, at room temperature
½ teaspoon vanilla extract
½ cup/113 grams unsalted butter, melted
1 ⅓ cup/170 grams all-purpose flour
2 teaspoons baking powder
1 teaspoon ground cardamom
Pinch of salt
Preparation
- Step 1
Heat oven to 350 degrees. Generously butter a 9-inch springform pan. Coat the bottom of the pan evenly with light brown sugar. Toss plum slices with lemon juice, then arrange in a single layer on the sugar, skin side down. Set aside.
- Step 2
Put granulated sugar in the bowl of a stand mixer fitted with whisk attachment (or in a sturdy mixing bowl if using a whisk). Add the eggs and vanilla, and beat on medium until the mixture begins to thicken, about 5 minutes. Add butter. Increase speed a bit and continue beating until mixture is fluffy, another 5 minutes.
- Step 3
Sift together flour, baking powder, cardamom and salt. On low speed, add flour mixture to egg-sugar mixture. Stir briefly to incorporate into a smooth batter.
- Step 4
Spread the batter over the plums in the prepared pan. Bake until a tester inserted in the center comes out clean, about 1 hour.
- Step 5
Let the cake rest in the pan for 10 to 15 minutes, then invert over a cake platter. Loosen and remove pan. Cool completely to room temperature.

And what kind of plum? Three types are at my grocery store: very big black plums, medium size purple plums (round and slighty red skin) and small Italian prune plums. I just made the classic plum torte recipe (which does not specific what type of plum) and it was a total failure: the ripe purple plums I got stayed firm and did not cook down like in the picture. The result was: a boring white cake with hard plum halves on top. So before I do this recipe PLEASE let us know: WHAT KIND OF PLUMS?!
Approach with caution! The pear/plum confusion should have been a tip-off, but there are a number of problems. 1. The amount of plums called for is weirdly high and left me with a bunch of leftover slices (3-4 avg purple is enough). 2. Strongly recommend a parchment circle. 3. The beating times are way too long (maybe for by-hand vs. stand mixer)? I followed them against my better judgement and the batter collapsed. Cake still rose but had a chewy texture. Guessing 2-3 min is more accurate.
“Generously made with any kind of pear” while probably true, plum is in the title so is this from a different recipe? Perhaps I’ll try with 6 of one, half a dozen if the other.
Tastes great but turned out very soupy. I used 2 lb of small plums. Once I took the ring off (per instructions) it fell apart and sort of disintegrated.
Mine didn't look very pretty, but still tasted amazing. My husband said it was the best cake he'd ever tasted. Also suggested I make a second one right away. before plums go out of season.
20 minutes for prep?? I don't think so. Takes that long to slice the plums. also disappointed! Also, how to get pretty pink top pictured rather than brown, pale slices when flipped over? Many problems with this recipe.
