2 lbs black plums, ripe but still firm to the touch
1 1/2 sticks butter (12 tbsp)
3/4 cup brown sugar
1 1/2 cups flour
2 tsp baking powder
1/2 tsp cinnamon
1 tsp vanilla extract
1/2 cup milk
3/4 cup granulated sugar
1/4 tsp salt
Preheat oven to 350 degrees.
Slice the plums 1/4" thick using a sharp knife. This will be easier if the plums are ripe, but not so super juicy that they don't slice easily. Look for ones that are still a bit firm to the touch. After you slice your plums, set slices aside.
In a cast iron skillet, heat four tablespoons of the butter (1/2 stick). Melt butter and then continue to brown butter (head over here for a browning butter photo tutorial). Once butter has browned, immediately add the brown sugar and stir. Cook sugar and butter, stirring constantly, for three minutes. Pour mixture into a greased 9" cake pan, spreading all over the bottom of the pan using a rubber spatula.
Arrange the plum slices on top of the brown sugar/butter mixture in the cake pan. You should be able to get three circles of plum slices out of this, overlapping if necessary. Set aside.
Cream together the remaining stick of butter with the granulated sugar until fluffy. Add the eggs, one by one, beating constantly. Then, add the vanilla.
In another bowl, whisk together the flour, baking powder, salt and cinnamon. Add these dry ingredients alternately with the milk and continue beating until light and fluffy.
Spread cake batter right on top of the plums. Bake for 40-45 minutes until golden brown.
Let cool three minutes before saying a quick prayer and flipping cake pan over onto a large plate. Serve cake with vanilla ice cream!
