Heat oven to 375°F. Pour melted butter into ungreased 13x9-inch (3-quart) glass baking dish. Separate both cans of dough into 16 rolls; set icing aside. Cut each roll into 8 pieces; place pieces over butter in dish.
In medium bowl, beat eggs. Beat in cream, cinnamon and vanilla until well blended; gently pour over roll pieces. Sprinkle with pecans; drizzle with 1 cup syrup.
