Moist, lightly sweet with a jammy tartness you'll love. This delicious plum cake is versatile and can be served as a breakfast cake with coffee or topped with ice cream for a decadent summer dessert.
Preheat oven to 350°. Cut a piece of parchment paper into a 9" round to fit the bottom of a 9" x 2" cake pan. Spray the pan liberally with vegetable spray. Place the parchment in the bottom of the pan and spray again. Set aside.
Slice 5 plums into 6-8 wedges each and transfer to a bowl. Sprinkle with 1 tablespoon sugar and toss to coat. Set aside.
In a medium bowl, combine 1½ cups all purpose flour, ½ cup cornmeal, 1 teaspoon baking powder, ½ teaspoon baking soda, ¼ teaspoon salt. Whisk to combine and set aside.
In a large mixing bowl beat 8 tablespoons unsalted butter, ½ cup sugar and ½ cup brown sugar until creamy, about 2-3 minutes. Add 3 large eggs one at a time, beating each one in before adding the next. Add 1 teaspoon vanilla and mix to combine.
In two additions, alternate adding the flour mixture and ½ cup buttermilk to the sugar mixture. Don't overmix.
Spread 2/3 of cake batter evenly in the prepared pan. Arrange the plums in concentric circles starting at the edge and working your way around the pan.
Dollop the remaining batter over the plums (it doesn't need to cover them completely). Bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
Cool the cake on a wire rack until it reaches room temperature. Carefully turn the cake out onto a plate, remove the parchment paper, then flip it over onto a cake plate so the top side is up. Serve.
