Plum Shortcakes

Preheat grill to medium (300 to 350 degrees). Cut two 12-by-18-inch sheets of foil. Place half the plums in the center of each sheet; dot with butter. Fold up sides of foil and seal tops to form 2 packets. Place packets on a baking sheet.

Place baking sheet on grill rack. Grill 8 to 10 minutes. Remove baking sheet from grill.

Meanwhile, place marmalade in a medium microwave-safe bowl; microwave on HIGH 45 to 60 seconds or until melted. Stir in almond extract.

Carefully open foil packets; add plums to marmalade in bowl; stir. Spoon plum mixture on each shortcake. Top with 1 tablespoon whipped topping. Sprinkle with almonds, if desired, and serve immediately.
