Add eggs and vanilla; beat until incorporated. With mixer on low speed, alternately add the flour mixture in three parts and the milk in two, beginning and ending with the flour mixture. Spoon batter over apples in pan; smooth top. Bake until toothpick inserted in center comes out clean, 35 to 45 minutes.
