This is one of Sam's favorites!
1 can cream of coconut
1 box of white cake mix
1 can sweetened condensed milk
1 small container of cool whip
Coconut to sprinkle on top
1 box of white cake mix - prepare as directed on the box in a cake pan - not layers.
Let the cake cool. Poke holes in it w/the end of a wooden spoon or something like that.
In a bowl, stir together until blended 1 can cream of coconut and 1 can sweetened condensed milk. Pour this mixture over the cake, letting some of it soak into the holes. Top with cool whip (usually a small container works) and sprinkle coconut on top. Refrigerate.
