Pour boiling water on chocolate in small bowl, stirring until chocolate is melted; cool. Beat egg whites until stiff.

Mix sugar and butter in large mixer bowl until light and fluffy. Beat in egg yolks, one at a time. Beat in chocolate and vanilla on low speed. Mix in flour, baking soda and salt alternately with buttermilk, beating after each addition until batter is smooth. Fold in egg whites. Divide batter among pans.

Bake until toothpick inserted in center comes out clean, 45 to 50 minutes for 8-inch square layers, 40 to 45 minutes for 9-inch square layers, 35 to 40 minutes for 8-inch round layers, 30 to 35 minutes for 9-inch round layers. Cool. Fill layers and frost top of cake with Coconut-Pecan Frosting.

not a recipe but a question
My sister in Law has mentioned several times that she is having a problem with her german choc cake uses the recipe on the back of the chocolate (german). For years it did great then it started falling. She has tried many things and it still falls. Any idea of the problem? I want to try and make it for her but don't want it to fall. I'm thinking that she makes it in a oblong pan but not sure of that and she frosts it with 7 min frosting not sure why I love the coconut/pecan frosting
