Quick and Simple Plum Cake Recipe

Preheat the oven to 350 degrees F (175 degrees C). Grease an 10-inch springform pan.

Sprinkle prepared plums with lemon juice in a bowl.

Combine flour butter sugar eggs sour cream baking powder salt and lemon zest in the bowl of a food processor; pulse until blended. Process on low speed until smooth. Pour batter into the prepared springform pan.

Arrange plums cut-side down on the batter. They can touch or even overlap; the more plums you can fit the better the cake. Dust with cinnamon.

Bake in the preheated oven until a toothpick inserted into the center comes out clean 45 to 50 minutes. Cool on a wire rack for 15 to 20 minutes before serving. Run a table knife around the edges to loosen. Invert carefully onto a serving plate. Dust with confectioners' sugar.
