Preheat the oven to 350 degrees F. In a large mixing bowl, combine eggs, sugar, melted butter and milk. (I used an electric hand mixer). Add vanilla, coconut extract (if using) and Bisquick, mix well.
Stir in the shredded coconut. Pour mixture in a pie pan and bake for approximately 1 hour or until the center sets and the top is golden brown.
Remove from the oven and let sit for at least 30 minutes before serving (this will let the custard firm up a little more). If you will not be serving right away, store in your refrigerator until you are ready to do so.
