Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking pan.

In a medium mixing bowl, combine the cake mix, melted butter, and one egg until the mixture forms a cohesive dough.

Press the cookie dough into the bottom of the prepared baking pan evenly.

Whisk together the sweetened condensed milk, vanilla extract, the remaining egg, chopped pecans, and shredded coconut.

Once the cookie base is done baking, pour the coconut pecan mixture over it evenly and sprinkle milk chocolate chips on top.

Bake for an additional 24-30 minutes until lightly golden brown and set.

Remove from the oven, cool completely in the pan, then refrigerate for an hour before cutting into squares.
