1 cup unsifted unsweetened cocoa 
2 cups boiling water 
2 3/4 cups 1) all-purpose flour 
2 teaspoons baking soda 
½ teaspoon salt 
½ teaspoon baking powder 
1 cup butter or regular margarine, softened 
2 1/2 cups granulated sugar 
4 eggs 
1 1/2 teaspoons vanilla extract 
 
1 pkg (6 oz.) semisweet chocolate pieces 
1/2 cup light cream 
1 cup butter or regular margarine 
2 1/2 cups unsifted confectioners' sugar
 
1 cup heavy cream, chilled 
1/4 cup unsifted confectioners' sugar 
1 teaspoon vanilla extract
 
-  In medium bowl, combine cocoa with boiling water, mixing with wire whisk until smooth. Let cool completely. 
-  Sift four with soda, salt, and baking powder. Preheat oven to 350F. Grease well and lightly flour three 9-by-11/2-inch layer cake pans. 
-  In large bowl of electric mixer, at high speed, beat I cup butter, the granulated sugar, eggs and 11/2 teaspoons vanilla, scraping bowl occasionally with rubber scraper, until light –about 5 minutes. At low speed, beat in flour mixture (in fourths), alternately with cocoa mixture (in thirds), beginning and ending with flour mixture. Do not overbeat. Divide evenly into prepared pans; smooth tops. 
-  Bake 25 to 30 minutes, or until surface springs back when gently pressed with fingertip.  
-  Cool in pans 10 minutes. Carefully loosen sides with spatula; remove from pans; cool [completely] on wire racks. 
 
-  In medium saucepan, combine chocolate pieces, crea and butter; stir over medium heat until smooth. Remove from heat. 
-  With wire whisk, blend in 21/2 cups confectioners' sugar. In bow set over ice, beat until it holds shape. 
 
-   Whip cream with confectioners' sugar and vanilla; refrigerate. 
 
-  Place a cake layer on serving plate, top side down; spread with half of filling. Place second layer top side down; spread with rest of filling. Place third layer, top side up, on top. 
-  With spatula, frost side first, covering whipped cream; use rest of frosting on top, swirling decoratively.  note: you may not need to use all the frosting – I don't because my cakes made with French flour are not as tall– and it shouldn't be too thick or the cake will seem too sugary.  Refrigerate at least 1 hour before serving. 2)- .   
-  To cut, use a sharp, thin-bladed knife; slice with a sawing motion.
