Ugly Green Plums, Olive Oil, and Cornmeal Cake (Kopie)

*****

cake recipe inspired by David Lebovitz's Ready for Dessert
makes one 9 x 13" cake

2 Tbspn (20 gr) + 3/4 cup (130 gr) stone-ground yellow cornmeal
1 cup (140 gr) AP flour
2 tspn baking powder
1 tspn salt
1/2 cup olive oil
6 large eggs, at room temperature
1 tspn vanilla extract
1/2 cup butter
2/3 cup (132 gr) sugar
2/3 cup (~120 gr) dark brown sugar, lightly packed
3-4 small green plums

1. Preheat oven to 350 degrees F. Grease the bottom and sides of a 9x13" baking pan, and dust the insides with 2 Tbspn (20 gr) of cornmeal. If desired, wrap with bake-even strips. Set aside.
2. Whisk to combine the flour, remaining 3/4 cup (130 gr) cornmeal, baking powder, and salt.
3. In a separate bowl, whisk together the olive oil, eggs, and vanilla extract.
4. In a mixer bowl using the paddle attachment, cream the butter and sugar until light and fluffy, about 3-5 minutes. Slowly add the egg mixture, a little at a time while still beating. Stir in the flour mixture in two additions, but do not overmix.
5. Pour the batter into the prepared cake pan. Slice the plums and arrange the slices on top of the batter. Bake for 30-40 minutes until a toothpick inserted into the cake comes out cleanly. Let cool for 30 minutes before inverting onto a wire rack to cool. Top with powdered sugar, if desired.
