- 2 teaspoons unsalted butter, softened
- 1/2 cup sugar
- 8 ounces semisweet chocolate, finely chopped
- 4 large egg whites
- 3 large egg yolks
- 1/4 cup Grand Marnier
- 3/4 cup Chocolate Grand Marnier Sauce 
- Confectioners' sugar
Preheat the oven to 400 degrees F. Using the butter, grease 4 individual ramekins and sprinkle them with about 1 teaspoon sugar per ramekin.
In a large metal bowl set over a pot of simmering water, melt the chocolate, stirring it with a whisk from time to time. Remove the bowl of melted chocolate from the heat.
In another bowl beat the egg whites with 1/4 cup of the sugar until stiff and glossy.
Whisk the egg yolks into the chocolate one at a time, add the Grand Marnier, and whisk in the remaining 2 tablespoons sugar. Fold in the egg whites and whisk until thoroughly blended
Pour the chocolate mixture into the prepared ramekins, place on a baking sheet, and bake until theyíre puffed and somewhat firm, for about 20 to 25 minutes. Remove from the oven.
While the soufflÈs are baking, prepare the Chocolate Grand Marnier Sauce, and cover to keep warm.
To serve, place a ramekin on each of 4 plates and sift powdered sugar over the top of each soufflÈ. Break the tops of the soufflÈs and spoon in the warm Chocolate Grand Marnier Sauce, allowing it to drip over the sides.
