Beat cream cheese, brown sugar, coconut, coconut extract and egg until light and fluffy. Add a small pinch of salt.
Pour mixture into partially baked pastry shell to create a thin, even layer. Add pineapple rings as a topping, cutting in half to fit as necessary.
Bake filled pie in the hot oven for around 20 minutes or until filling sets.
While the pie is baking, mix pineapple juice with sugar and cornstarch in a small saucepan. Cook over low heat, stirring constantly, to create a glaze.
Remove cake from oven and spoon glaze evenly over the surface.
Cool pie to room temperature, then refrigerate until completely chilled. Serve and enjoy!
