Heat oven to 350°F. Spray bottom and sides of 13x9-inch pan with cooking spray. Unroll dough; press in bottom and 1/2 inch up sides of pan.
In large bowl, beat cream cheese, sugar, flour, vanilla and egg with electric mixer on medium speed until smooth.
Spread cream cheese mixture evenly over dough. Spoon apple pie filling evenly over cream cheese mixture. Sprinkle with crushed granola bars.
Bake 32 to 35 minutes or until crust is deep golden brown and filling is set. Cool 30 minutes. Refrigerate 2 hours. For bars, cut into 6 rows by 4 rows. Drizzle each with maple syrup. Cover and refrigerate any remaining bars up to 3 days.
