Tres Cocos Cake (Three Coconuts Cake) - This is one of my favorite coconut cakes. I DON'T toast the coconut. To the topping, I ADD 2 tsp unflavored gelatin. I ADD 1/3 cup sour cream to the Cool Whip and blend together before spreading over the top of the cake. If you are out of coconut pudding, you can substitute 1 pkg of vanilla pudding + 1/2 tsp coconut flavoring.
