Preheat oven to 350°.
Coat a 10-inch tube pan with cooking spray, and dust with 2 teaspoons flour. Set prepared pan aside.
Beat granulated sugar and next 8 ingredients (sugar through eggs) at medium speed of a mixer until blended. Lightly spoon flour into dry measuring cups; level with a knife. Combine flour, baking powder, and salt. Add flour mixture to sugar mixture, beating at low speed just until blended. Combine apple and remaining ingredients. Spoon half of batter into prepared pan. Top with half of apple mixture. Repeat with remaining batter and apple mixture. Bake at 350° for 1 hour and 15 minutes. Cool 10 minutes in pan on a wire rack; remove from pan. Cool completely on wire rack.
