- 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.
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.
