Sweet sliced peaches are arranged in the bottom of a cake pan and topped with a sweet cornbread cake mixture. The peaches caramelize in the butter and brown sugar mixture and make for an elegant cake topping.
Butter a 9-inch cake pan and cut a 9-inch circle of parchment paper and press it into the bottom of the pan. Drizzle 6 tablespoons of the butter (half) around the bottom of the pan and sprinkle with brown sugar. Arrange slices of peaches in the bottom of the pan.
In a large mixing bowl stir together the cornmeal, flour, sugar, salt and baking powder. In another medium mixing bowl whisk together the remaining butter, eggs and buttermilk. Use a wooden stone to mix the buttermilk mixture into the dry ingredients until just combined.
Spread the batter evenly over the peaches and bake until a knife inserted into the center comes out clean, about 40 minutes.
Let cool completely, about 20 minutes, then place a serving plate over the top of the pan and carefully flip the cake over. Wait one minute then remove the pan from the cake. Cut into slices and serve.
