Ingredients
Preparation
Step 1
Preheat the oven to 350°F. Brush a 9-inch-square cake pan or 10-inch cast-iron skillet with 2 tablespoons butter; set aside. Whisk together the flour, 3/4 cup sugar, and the baking powder, allspice, and 3/4 teaspoon salt in a medium bowl; set aside.
Step 2
Whisk together the egg, milk, vanilla, and remaining 4 tablespoons butter in another medium bowl. Add the egg mixture to the flour mixture; stir to combine. Spread the batter evenly into the buttered pan.
Step 3
Toss the plums, nectarines, lemon juice, remaining 1/4 cup plus 2 tablespoons sugar, and a pinch of salt in a large bowl. Spread the fruit mixture evenly over the batter. Sprinkle with the topping. Bake until a cake tester inserted into the center comes out with moist crumbs, about 1 hour and 15 minutes. Let cool in the pan on a wire rack 1 hour before serving.
