In a large saucepan, bring the water, milk, butter and salt to a boil. Add flour all at once and stir until a smooth ball forms. Remove from the heat; let stand for 5 minutes. Add eggs, one at a time, beating well after each addition. Continue beating until mixture is smooth and shiny.
Drop by 1/4 cupfuls into a 10-in. ring on a greased 12-in. pizza pan (mounds should be slightly touching). Bake at 400° for 40-45 minutes or until golden brown.
Remove to a wire rack. Immediately cut a slit in the side of each puff to allow steam to escape. Carefully cut ring in half horizontally and set top aside; remove soft dough from inside with a fork. Cool.
In a small bowl, whisk the milk, sour cream, pudding mix and 1/4 teaspoon extract for 2 minutes. Let stand for 2 minutes or until soft-set.
Just before serving, place bottom of cream puff ring on a serving plate. Fill with pudding mixture. In a small bowl, beat the cream, confectioners' sugar and remaining extract until stiff peaks form. Spread over pudding. Top with pie filling. Replace cream puff ring top. Sprinkle with confectioners' sugar. Yield: 12-16 servings.
