3 pkg. ladyfingers, split lengthwise
3 (6 oz. size) pkg. semi-sweet chocolate pieces
1 c. granulated sugar
1 tsp. vanilla extract
8 eggs, separated
Confectioners sugar

Line side and then bottom of a 9 inch springform pan with ladyfingers, split side in. Set aside.

In medium saucepan, combine chocolate pieces, granulated sugar and 1/2 cup water. Over low heat, stir constantly until chocolate is melted and sugar dissolved. Remove from heat. Add vanilla, and beat with wooden spoon until smooth. Set aside and let cool slightly.

In large bowl, with portable mixer at medium speed beat egg yolks slightly. Gradually add chocolate mixture beating constantly, continue beating until it thickens.

With clean beaters, beat egg whites just until stiff peaks form when beaters are slowly raised. With wire whisk or rubber scraper, using under and over motion gently fold beaten egg whites into chocolate mixture just until combined. Spread a fourth of chocolate mixture over ladyfingers in springform pan. Cover mixture with a layer of ladyfingers. Repeat 3 times. Refrigerate 4 hours. Dust with confectioners sugar.
