The cake is chock full of juicy summer peaches, and the addition of ground almonds sets it apart from other simple butter cakes. It's luscious and a bit custardy in the areas surrounding the peaches -- a texture that works when the cake is either warm or at room temperature.
Preheat the oven to 350°F. Butter and flour a 9-inch cake pan. Cut the peaches into bite-sized pieces. Toss the peaches with nutmeg and 2 tablespoons sugar. Set aside.
Cream together the butter and remaining sugar with a wooden spoon or spatula. Add the egg, buttermilk and extracts, and stir to combine. Combine the flours, baking powder, baking soda and salt. Add this flour mixture to the butter mixture, and blend until smooth (some lumps may remain). Pour into the prepared pan. Press the peaches into the top of the cake. They can be nicely arranged, or you can cram as many peaches as possible into the cake. Sprinkle turbinado sugar over the top.
Bake for 10 minutes, then reduce the oven heat to 325°F and bake for an additional 45 to 55 minutes, or until a toothpick inserted in the center comes out clean.
