Three Milk Banana Heaven Cake

This is one of my hubby's favorite cakes. Very, very yummy! I've made it for family a few times now and it's always a hit.

Ingredients: 1 box white cake mix (I get betty crocker supermoist...but I don't think it matters....)
                    1 1/4 cups water
                    2 T. veggie oil
                   3 eggs
                    1 cup mashed banana (about 2 to 2 1/2 bananas)
                  1 can (14oz.) sweetened condensed milk
                    1/2 cup coconut milk (NOT cream of coconut!) I have never seen it at walmart...I always have to go to Kroger...and it's in the liquor aisle.
                   1/2 cup whipping cream
                    1 container whipped fluffy white frosting
                 extra banana and coconut flakes for the top *optional*

Directions: Heat oven to 350. Grease the Bottom Only of a 13x9  pan with spray.
  In a large bowl, beat the cake mix, water, oil, eggs and mashed bananas with electric mixer for 30 seconds on low, then about 2 minutes on medium speed.
  Pour into pan and bake for about 30-35 minutes or until done. Cool completely. (about 1 hour)
 Poke top of cake about every 1/2 inch with a long tined fork...or whatever works,...because honestly who has one of those?? Not me, I just used a baby spoon, but I flipped it around and used the end you hold it with. Perfect! So you'll find something around your house to use!
   In a large bowl, stir together the condensed milk, coconut milk and whipping cream. Carefully pour evenly over top of cake. Cover and refrigerate at least 2 hours or overnight until mixture is absorbed into the cake.
   Then, spread the frosting over the cake and top with shredded coconut and fresh banana slices.
Store covered in refrigerator.
