In a mixing bowl, combine the yellow cake mix, sweetened condensed milk, eggs, melted butter, coconut milk, shredded coconut, vanilla extract, and salt. Mix until well combined.
Pour the mixture into a greased baking dish.
Bake for 45 minutes or until the top is golden brown and a toothpick inserted comes out clean.
Let it cool slightly before serving.
