Combine first six ingredients in medium bowl. Set aside.
Combine sugars, buttermilk, vegetable oil, eggs and vanilla in
a large bowl; stir until all ingredients are well blended. Add
flour mixture, carrots, pineapple, walnuts and coconut, stirring
just until well blended.
Cream cheese frosting- 1/2 c. Butter, softened; 1 (8 oz) cream
cheese, softened; 16 oz powdered sugar. Combine butter and
cream cheese in a large bowl. Add powdered sugar, mixing
well. (Icing is thick. I double the recipe as it's easier to cover
the entire cake )
