1 white cake mix
1 can sweetened condensed milk
1 can cream of coconut mixer (found on the mixed drink aisle)
1 (8 oz.) Cool Whip

Mix cake mix according to package directions and bake. Let cool. Poke holes with a fork every inch or so. Pour 1 can sweetened condensed milk over top. Then pour 1 can cream of coconut over the cake slowly, mixing well before pouring. Top with Cool Whip and frozen coconut. Make this at least 1-2 days before you need it to let the flavors soak in. A really moist coconut cake.
