White Three-Layer Butter Cake With White Chocolate Frosting - cake flour

Method

• Grease and lightly flour three 8x1-1/2-inch or 9x1-1/2-inch round baking pans. Set aside.
• In a medium bowl, sift together flour, baking powder, and salt; set aside.
• In a large bowl, beat butter with an electric mixer for 30 seconds. Add 1 cup sugar and the vanilla; beat until fluffy. Add the flour mixture alternately with half-and-half to creamed mixture, beating on low to medium speed after each addition just until combined.
• Clean beaters. In another large bowl, beat egg whites on medium to high speed until soft peaks form (tips curl). Gradually add 1 cup sugar and beat on high speed until stiff peaks form (tips stand straight). Gently fold the egg whites, about 1/4 at a time, into creamed mixture. (If necessary, transfer mixture into a larger bowl.).
• Divide mixture into prepared pans. Bake in a 350 degree F oven about 30 minutes for 8-inch rounds and about 25 minutes for 9-inch rounds or until a toothpick inserted near centers comes out clean*. Cool layers in pans on wire racks for 10 minutes. Remove the layers from the pans and completely cool on wire racks.
• Frosting: In a heavy saucepan, melt 18 ounces chopped white chocolate baking squares or bars over low heat. Cool until slightly warm. In a large bowl, beat one softened 3-ounce package cream cheese with an electric mixer until smooth. Cut 1-1/2 cups butter into pieces. Add to cream cheese; beat until fluffy. Gradually add cooled chocolate, beating until well blended.
• Frost. Cover and refrigerate. Let stand at room temperature for 30 minutes before serving. Makes 16 servings.
