Preheat oven to 350 degrees F.
Unroll crescent dough and arrange 12 of the triangles in a circle with wide ends toward the outside edge of the Large Round Stone - the points will not meet in the center. Lightly flour and roll out the seams making a 14" circle with a 3" hole in the center. Combine the cream cheese, powdered sugar, egg & vanilla and spread over dough. Top with pie filling. Cut each of the 4 remaining triangles into thirds (starting at the wide end opposite the point and cutting lengthwise to the point). Arrange over filling evenly in spoke-like pattern. Press ends to seal at center and outer edges.
Bake 25-30 minutes or until golden brown. Cool slightly. Mix powdered sugar and milk until glaze consistency and drizzle over coffee cake.
