1. Heat oven to 350°F. Grease and flour three 9-inch round baking pans.
2. Stir together cocoa and water in small bowl until smooth; set aside. Beat butter, sugar and vanilla in large bowl until light and fluffy. Add eggs, one at a time, beating well after each addition. Stir together flour, baking soda and salt; add to butter mixture alternately with chocolate mixture and buttermilk, beating just enough to blend. Pour batter into prepared pans.
3. Bake 25 to 30 minutes or until top springs back when touched lightly. Cool 5 minutes; remove from pans to wire racks. Cool completely. Prepare COCONUT PECAN FROSTING; spread between layers and over top. Makes 12 servings.
* To sour milk: Use 1 tablespoon white vinegar plus milk to equal 1 cup.
