Chocolate Mousse Cake with Liqueur

BATTER

• 1/2 cup granulated sugar
• 1/2 cup water
• 8 tablespoons (1 stick) unsalted butter
• 12 ounces semisweet or bittersweet chocolate, cut into 1/2-inch pieces
• 1/3 cup sweet liqueur, such as Cointreau or Chambord (or strong coffee)
• 6 eggs

FINISHING

• 1 cup heavy whipping cream
• 2 tablespoons sugar
• One 1/2-pint basket fresh raspberries, optional
• One 8-inch round pan, buttered and the bottom lined with buttered parchment or buttered wax paper, cut to fit

This unusual cake may be made in advance. Just make sure to bring it to room temperature before serving it with whipped cream and a few raspberries.

1. Set a rack at the middle level of the oven and preheat to 325 degrees.
2. Combine the sugar and water in a saucepan and bring to a boil over low heat, stirring occasionally to make sure all the sugar crystals dissolve.
3. Remove the syrup from the heat and stir in the butter and chocolate; allow to stand 5 minutes. Whisk smooth.
4. Whisk liqueur, then the eggs, one at a time, into the chocolate mixture. Be careful not to overmix.
5. Pour the batter into the pan and place in a small roasting pan. Pour 1 inch of warm water into the roasting pan. Bake about 45 minutes, until dessert is set and slightly dry on the surface. Remove cake pan from roasting pan. Cool to room temperature, then cover with plastic wrap. Refrigerate dessert in pan several hours or until chilled. To unmold, run a knife between the dessert and the pan and pass the bottom of the pan over heat for no more than 10 seconds. Invert onto a platter.
6. To finish, whip the cream with the sugar until it holds a soft peak. Spread the whipped cream over the top of the dessert. Decorate the top with the raspberries.
