Melt butter in the bottom of a 9x13 pan. Sprinkle graham cracker crumbs over butter. Stir with a fork until combined. Spread evenly over bottom of pan and pat down slightly with the back of the fork to form crust.
Sprinkle white chocolate chips evenly over crust. Layer chopped macadamia nuts evenly over white chocolate chips. Spread Baker's Coconut in a layer over the macadamia nuts. Pour sweetened condensed milk over the layers.
Bake at 350°F for 30 to 45 minutes, until coconut is lightly browned. Remove from oven and cool to room temperature before cutting. Cut into bars. Enjoy!!!
