2large eggsroom temperature

Instructions
Preheat oven to 350°F. Lightly grease and flour a 9-inch springform pan or 9-inch square baking pan. Set aside.
In a medium mixing bowl whisk together the flour, almond flour, salt, baking powder and baking soda. Set aside.
In a small bowl whisk together the buttermilk, vanilla and almond extracts. Set aside.
In a large mixing bowl combine the butter and sugar. Beat with an electric mixer until light and fluffy, about 3 minutes. With the mixer on medium-low add the eggs one at a time mixing just until the yolk disappears.
With the mixer on low the add 1/3 of the flour mixture and blend just until incorporated. Add half the buttermilk and beat until combined. Repeat adding half the remaining flour mixture, then all the buttermilk. Finally add all remaining flour and mix lightly until incorporated. Scrape down the sides and bottom of the bowl using a spatula. Fold the batter a few times to ensure it’s well blended. The batter will be thick.
Scoop the batter into the prepared pan and smooth the top with a spoon or offset spatula. Fan pieces of plums into groups around the top. You can do as many plums as you wish and even cover the top completely if desired. Sprinkle with coarse sugar and bake for 40 to 45 minutes or until a toothpick inserted in the center comes out with no wet batter. Moist crumbs are okay. Top with sliced almonds about 10 minutes before the cake is due to come out of the oven. Cool in the pan for 30 minutes. Remove the sides and transfer to a wire rack to cool.
Serve dusted with powdered sugar and/or a dollop of whipped cream
