1 pkg. yellow cake mix
1 1/2 c. sweet milk
1/2 c. sugar
2 c. grated coconut

Prepare cake as directed on package. Cool 15 minutes. Poke holes through cake with fork. Combine milk, sugar, and 1/2 of coconut in saucepan. Bring to a boil, reduce heat, and simmer 1 minute. Spoon over cake, allowing liquid to soak through holes. Cool completely.

Fold 1/2 of remaining coconut into Cool Whip and spread over cake. Sprinkle with remaining coconut. Chill overnight.
