Rustic Plum Cake

This cake is a modern take on grandmother's kitchen: a tender, buttery bed into which sweet, juicy plums sink. Unlike yeast-based versions, this batter comes together quickly, with a texture balancing between sponge cake and butter cookie. The cinnamon sugar caramelizes with the fruit juices during baking, filling the kitchen with irresistible aroma.

Instructions

1

Cream butter and powdered sugar until pale, then beat in eggs one by one.

Tip: Creaming aerates the fat, creating a lighter cake.
2

Stir in sour cream, then fold in sifted flour, baking powder, and salt. Mix just until combined.

Tip: Overmixing develops gluten and makes the cake tough.
3

Spread batter into a greased and floured pan.

Tip: Greasing prevents sticking.
4

Halve or quarter plums and arrange them cut-side up on the batter.

Tip: Cut-side up prevents excess juice from making the dough soggy.
5

Mix granulated sugar with cinnamon and sprinkle generously over fruit.

Tip: Sugar creates a syrup with fruit juices.
6

Bake at 350°F (180°C) for 35-40 mins until a toothpick comes out clean.

Tip: Baking powder activates with heat to rise the cake.

Recipe FAQ

Plums too sour?
Toss plum pieces in cinnamon sugar before placing them on the dough, not just on top.
Dense, heavy dough?
You likely overmixed after adding flour. Mix only until just combined!
Fruit sank to bottom?
Normal for this batter, but tossing fruit in a little flour helps keep them suspended.
