Meanwhile, in small bowl, toss 3/4 cup flour, the brown sugar, butter and 1/4 teaspoon pumpkin pie spice until crumbly. Set aside.
In medium bowl, beat remaining ingredients except whipped cream with wire whisk until smooth. Pour over apples. Sprinkle with flour mixture. Bake 30 to 35 minutes or until golden brown and set. Cool 20 minutes. Serve warm with whipped cream.
