4 sq. (4 oz.) unsweetened baking chocolate
1 (14 oz.) can sweetened condensed milk (not evaporated)
2 tsp. vanilla extract

In 2-quart glass measure or large microwave-safe bowl, place chocolate, sweetened condensed milk and vanilla. Microwave at HIGH (100%) 2-4 minutes, stirring after each minute, until chocolate is melted and mixture is smooth when stirred. Cool to room temperature about 1 1/2 hours. Beat until smooth.

In large mixer bowl beat whipping cream until stiff. Gradually fold into chocolate mixture. Pour into baked shell. Refrigerate 4 hours or until set. Garnish as desired. Refrigerate leftovers. Makes 6-8 servings.
