Directions

1. Preheat oven to 350 degrees. Combine 6 tablespoons butter and 3/4 cup brown sugar in a medium skillet, and cook over medium-high heat, stirring constantly, until melted and thoroughly combined, about 6 minutes. Pour into a 10-by-2-inch professional round cake pan.
2. Peel pears, core, and slice into 1/2-inch-thick wedges. Coat with lemon juice, and arrange on top of brown-sugar mixture in a spiral pattern around edge of pan. Fan out slices in center. Sprinkle 1/2 cup cranberries over pears, and set aside.
3. Sift flour, baking powder, salt, cinnamon, and ginger together in a medium bowl, and set aside. Combine remaining 6 tablespoons of butter with remaining cup brown sugar in the bowl of an electric mixer, and beat until well combined. Add eggs one at a time, beating after each addition. Add milk alternately with flour mixture, beginning and ending with four; beat until smooth. Stir in remaining 1/2 cup cranberries; pour over fruit in pan. Bake until a tester inserted in the center of cake comes out clean, about 40 minutes.
4. Transfer to a wire rack to cool for 15 minutes. Run a knife around eggs and invert onto a serving platter. Serve with spice ice cream.
