Preheat oven to 350 degrees. Grease a 9 X 13 inch baking dish; set aside.
In a large bowl, mix together cake mix, eggs, coconut milk, water, butter, vanilla and coconut flavor on low for 30 seconds.
Turn speed up to medium and mix together for 1-2 minutes, or until combined.
Pour batter into prepared baking dish.
Bake for 20-30 minutes, or until a toothpick inserted in center comes out clean.
Using a handle of a wooden spoon (or similar instrument), poke holes in the cake ( approximately 35).
Pour the lemon fruit filling over warm cake, gently spreading as necessary.
Let cake cool to room temperature.
To make the frosting, beat butter until smooth, about 1-2 minutes.
Add coconut milk, powdered sugar, and vanilla extract. Beat until well combined.
Stir in pinch or two of salt, to taste.
Spread frosting over cooled cake, and top with coconut chips.
Store leftovers covered in fridge.
