Preparation
In a large bowl, cream butter, shortening and sugar until light and fluffy. Add eggs and yolks; mix well. Combine the flour, baking powder and baking soda; add to the creamed mixture alternately with buttermilk. Beat in extract.
Pour into three greased and floured 9-in. round baking pans. Bake at 350° for 30 -35 minutes or until a toothpick inserted in the center comes out clean. Cool for 10 minutes before removing from pans to wire racks.
In a heavy saucepan, combine the sugar, egg whites, water and cream of tartar. With a portable mixer, beat on low speed for 1 minute. Continue beating on low speed over low heat until frosting reaches 160°, about 9 minutes. Pour into a large bowl; add vanilla. Beat on high until frosting forms stiff peaks, about 7 minutes.
Place one cake layer on a serving plate; spread with 1/2 cup frosting and sprinkle with 1/3 cup coconut. Repeat. Spread remaining frosting over top and sides of cake; sprinkle remaining coconut over the top.
