It is definitely NOT low calorie, but oh-so-yummy. Once in a while you just want to say 'Gimmie some sugar' ~This is just what you need. 
This recipe is very similar to the coconut cake that Mr. Mac always made at the WhistleStop Cafe. People are still asking what happened to that cake. The new owner doesn't serve it anymore... but you can make it at home!
Coconut Cake
1 white cake mix
3 eggs
1 1/4 cups water
1/3 cup oil
1 cup cream of coconut
1 cup sweetened condensed milk
1 tub cool whip
1 small container vanilla yogurt
1 cup coconut flakes
Combine the cake mix with the eggs, water, and oil. Pour into a buttered 9x13 baking dish or into a spring form pan. Bake as directed on the box. The cake will be done when a toothpick comes out clean. When cooled, poke holes around the cake with a straw. Combine the cream of coconut and the sweetened condensed milk. Gently pour over the cake, allowing it time to seep into the holes. Combine the cool whip and the vanilla yogurt for a creamy 'icing'. Cover the cake generously with the icing. Top with coconut flakes.
This cake is really better the second day. So plan to make it a day ahead and store in the fridge. This is a dessert that only gets better as time goes by! If it lasts that long.
Y'all enjoy!
