Heat oven to 350 degrees. Grease and flour jelly roll pan (15 1/2x10 1/2x1 inch). Mix sour cream, water, and eggs in large bowl. Stir in cake mix (dry) until moistened. Batter will be slightly lumpy. Spread in pan. Drop pie filling by generous spoonfuls onto batter. Bake 30-35 min. or until cake springs back when touched lightly. Cool. Sprinkle with almonds. Mix powdered sugar, milk, and almond extract for glaze. Drizzle over coffee cake.
