Ingredients:
1 package white cake
14 oz cream of coconut (from the alcohol section)
14 oz can sweetened condensed milk
1 16 oz tub Cool Whip
8 oz flaked coconut
Directions:
Prepare and bake white cake mix according to package directions. Remove cake from oven. While still hot, using a utility fork, poke holes all over the top of the cake.
Mix cream of coconut and sweetened condensed milk together. Pour over the top of the still hot cake. Let cake cool completely then frost with the whipped topping and top with the flaked coconut. Keep cake refrigerated.
Notes: My cream of coconut came in a squeeze jar and was larger than 14 oz. I just squeezed the amount into the sweetened condensed milk can to get exactly 14 ounces. Also, if making into a layer cake, make sure each layer is well greased in the pan, because once you pour the cream and the condensed milk, it's easy to have pieces stuck in the pan. Might be prettier as a 9x13. Also would be nice as an Easter Lamb cake.
