Servings: persons

1/2 cup plus 1 tablespoon unsalted butter, plus extra for the pan, at room temperature
4 firm, ripe plums, each cut into 8 wedges
1/4 cup plus 2/3 cup granulated sugar
1 cup all-purpose flour
3/4 teaspoon baking powder
1/4 teaspoon baking soda
1/4 teaspoon kosher salt
1 large egg
2/3 cup sour cream
1 teaspoon pure vanilla extract

1
Heat oven to 350 degrees. Butter an 8 inch cake pan and line the bottom with parchment paper.
2
Melt 1 tablespoon of the butter in a large skillet over medium-high heat. Add the plums and 1/4 cup granulated sugar and cook, tossing, until the sugar dissolves and the juices from the plums become syrupy, 3-4 minutes. Arrange the plumbs in the cake pan in slightly overlapping concentric circles, starting from the outside. Spoon any pan juices over the top.
3
In a small bowl, whisk together the flour, baking powder, baking soda, and salt.
4
With an electric mixer, beat the remaining 1/2 cup of butter and 2/3 cup of the sugar until fluffy. Beat in the egg, sour cream, and the vanilla. Gradually ad the flour mixture, mixing just until incorporated.
5
Pour the batter over the plums and bake until a toothpick inserted in the center comes out clean, 50-55 minutes. Let cool in the pan for 1 hour. Place a large plate over the cake pan and invert the cake onto the plate.
