Instructions
Preheat oven to 375 degrees.
Brown the butter in a 10" skillet over medium heat until it becomes an amber color and becomes aromatic. Use a wooden spoon to swirl the butter around the pan often.
Pour the butter into a large bowl, leaving a coating of melted butter in the skillet. To the mixing bowl, add buttermilk, eggs, granulated sugar and vanilla. Beat with an electric mixer on medium-high speed until combined.
Combine the dry ingredients: whisk flour, baking soda, baking powder and salt in a medium bowl. Slowly beat the flour mixture into the wet ingredients on low speed until combined.
Sprinkle 1/4 cup turbinado sugar evenly onto the bottom of the prepared pan. Arrange cherries in a single layer on the bottom of the pan. Then, layer the sliced plums in an overlapping pattern. Sprinkle the fruit with another 1/4 cup turbinado sugar. Pour batter over the fruit. Sprinkle the batter with the remaining 1/4 cup sugar.
Place a baking sheet on the bottom oven rack to catch any drips. Bake 45 minutes, until golden brown. Cool to room temperature on a wire rack before inverting onto a serving plate.
