1. Preheat oven to 425°F. Butter 4 (6-ounce) custard cups or soufflé dishes. Place on baking sheet.
2. Microwave chocolate and butter in large microwavable bowl on HIGH 1 minute or until butter is melted. Stir with wire whisk until chocolate is completely melted. Stir in wine, vanilla and confectioners' sugar until well blended. Stir in eggs and yolk. Stir in flour, cinnamon, ginger and cloves. Pour batter evenly into prepared custard cups.
3. Bake 13 to 15 minutes or until sides are firm but centers are soft. Let stand 1 minute. Carefully loosen edges with small knife. Invert cakes onto serving plates. Sprinkle with additional confectioners' sugar. Serve immediately.
Make Ahead: The chocolate mixture can be prepared up to 1 day ahead of time. Pour the batter into prepared custard cups; cover with plastic wrap and refrigerate. Bring to room temperature for 30 minutes before baking.
Test Kitchen Tip: Molten cakes prepared with Saigon Cinnamon will have a warm, flavorful cinnamon taste. Use Roasted Saigon Cinnamon for a robust, sweet-spicy cinnamon flavor.
