Preheat oven to 350 degrees F. Line a 9-inch springform pan with foil, smoothing out the wrinkles. Coat the foil with cooking spray. Sprinkle 2 tablespoons of the sugar in the bottom of the pan and set aside.Advertisement
Halve plums lengthwise and remove the pits. Cut each half lengthwise into thin slices. Arrange circular rows of overlapping slices in the prepared pan; place any remaining slices in an even layer on top.
Stir together cake flour and whole-wheat flour, the remaining 1 cup sugar, baking powder, baking soda, cinnamon, nutmeg and salt in a mixing bowl. Whisk together yogurt, oil, egg, egg white and vanilla in another bowl until well combined. Stir the yogurt mixture into the dry ingredients with a rubber spatula just until blended.
Gently spoon the batter onto the plums, smoothing the top. Bake until a skewer inserted in the center of the cake comes out clean, 40 to 50 minutes.
Remove the outer ring of the springform pan, fold back the foil, and invert the cake onto a cake plate. Remove the pan bottom and foil.
Whisk jelly in a small saucepan over low heat until melted. Brush over the top of the warm cake. Serve warm or at room temperature.
