preheat oven to 350°, rack in the middle position.

2 cups butter (4 sticks, 1 lb), melted
2 cups brown sugar
2 cups granulated sugar
4 eggs, beaten
1 teaspoon baking powder
1 teaspoon baking soda
1 teaspoon salt
2 teaspoons pineapple extract*
4 cups flour
2 1/2 cups chopped sweetened dried pineapple (measure AFTER chopping)
1/2 cup chopped coconut flakes (measure AFTER chopping)
3 cups rolled oats

melt the butter in a large microwave-safe bowl (about 3 minutes on HIGH). add the sugars and let it cool a bit. then add the beaten eggs, baking powder, baking soda, salt, and pineapple extract. mix in the flour. then add the chopped pineapple, chopped coconut, and rolled oats, mixing them in thoroughly. the dough will be quite stiff. drop by teaspoonful onto a greased cookie sheet. (i roll mine in a ball so the cookies turn out nice and round.) bake at 350° for 12-15 minutes. cool on the cookie sheet for 2 minutes and then remove them to a wire rack to cool completely.
