- 6 large eggs separated at room temperature
- 1 cup granulated sugar
- 1 tablespoon creme de cacao kahlua or dark rum
- 1/2 teaspoon vanilla extract
- 1 1/2 cups whipping cream well chilled
- 3 Tbsp. powdered sugar

- Place rack in the lower third of oven; preheat oven to 375 °F. Butter and flour a 9-inch spring form pan.
- In double boiler top over simmering water, melt chocolate with butter. Keep chocolate warm over a pan of warm water.
- In a large bowl of mixer, beat egg yolks at high speed. Gradually add 3/4 cup of the granulated sugar, beating until mixture is pale yellow and thick, 4-6 minutes. Add chocolate mixture to yolk mixture; beat until completely smooth.
- Add creme de cacao and vanilla; beat until blended. In a medium bowl of mixer, beat egg whites at high speed until soft peaks form. Gradually add remaining 1/4 cup sugar, beating until stiff but not dry peaks form.
