Heat oven to 375°F. Pour melted butter into ungreased 13 x 9-inch (3-quart) glass baking dish.
Separate both cans of dough into 16 rolls; set icing aside. Cut each roll into 8 pieces and place pieces in dish.
In medium bowl, beat eggs. Beat in cream, cinnamon and vanilla until well blended; gently pour over roll pieces.
Sprinkle with chocolate chips and drizzle with 1 cup syrup. Bake 20 to 28 minutes or until golden brown. Cool 15 minutes.
While that cools, remove covers from icing and place on a microwave safe plate. Microwave on medium (50%) 10 to 15 seconds or until thin enough to drizzle. Stir before drizzling.
Drizzle icing over top; sprinkle with powdered sugar. If desired, spoon syrup from dish over individual servings. Serve with the additional 1/2 cup maple syrup, if desired.
