Preheat oven to 350 degrees. On a lightly floured surface, unroll crusts. With a 4-inch round cutter, cut circles from pie crusts. Line 12 (3½-inch) removable-bottom tart pans with crust; prick bottoms of crusts with a fork. Place on a baking sheet, and bake for 5 minutes.
In a medium bowl, combine brown sugar, molasses, and corn syrup. Whisk in melted butter and eggs until well combined. Whisk in vanilla and salt. Stir in walnuts. Evenly divide filling between prepared crusts. Bake for 20 to 22 minutes or until lightly browned and center is set.
