Make the tart a day ahead, and store it in the refrigerator. You can use a 9-inch pie plate instead: simply roll the dough to a 13-inch circle, fold the edges under, and flute.
1 cup packed light brown sugar
3/4 cup dark corn syrup
3 tablespoons all-purpose flour
2 tablespoons bourbon
2 tablespoons molasses
1 tablespoon butter, melted
1/2 teaspoon vanilla extract
1/4 teaspoon salt
2 large eggs
1 large egg white
2/3 cup pecan halves
1/2 (15-ounce) package refrigerated pie dough (such as Pillsbury)
1/2 ounce bittersweet chocolate, chopped
How to Make It
Preheat oven to 350°.
Combine first 10 ingredients, stirring well with a whisk. Stir in pecans. Roll dough into a 13-inch circle; fit into a 9-inch removable-bottom tart pan coated with cooking spray. Trim excess crust using a sharp knife. Spoon sugar mixture into prepared crust. Bake at 350° for 45 minutes or until center is set. Cool completely on a wire rack.
Place chocolate in a microwave-safe bowl; microwave at HIGH 1 minute. Stir until smooth. Drizzle chocolate over tart.
