Preheat oven to 325 degrees. Prepare an 8-inch baking pan by spraying with non-stick spray w/ flour. You can even line the pan with foil or parchment paper, spray the paper with non-stick spray, this will allow for easy removal.
Add the oreos and melted butter to a food processor and blend until crumbs are fine. Pour the crumbs into the bottom of the prepared pan and press into the bottom. Bake at 325 for 10 minutes.
While the crust is baking and cooling, chop the dried pineapple into small pieces and blend the macadamia nuts in a food processor until crumbs are formed.
Start to layer the remaining ingredients onto the cooked crust. Sprinkle 1 cup of the white chocolate chips along the bottom, then sprinkle with the pineapple, coconut and nuts. Pour the sweetened condensed milk evenly over the top. Decorate the top with the remaining chocolate chips and a little coconut.
Turn the temperature up to 350 degrees. Bake for 30 minutes, just until the sides are starting to turn golden in color. Cool completely, then cover with foil and chill for a few hours. When ready to cut into bars, allow them to sit at room temperature for 10-15 minutes and then slice and enjoy!
