1Preheat your oven to 325°F (165°C) and line a baking sheet with parchment paper.
In a large mixing bowl, cream together the unsalted butter and brown sugar until light and fluffy.
Add the vanilla extract and mix until well combined.
Gradually add the all-purpose flour to the butter mixture, mixing until a dough forms.
Gently fold in the finely chopped dried pineapple and chopped macadamia nuts until evenly distributed.
Roll the dough into small balls, about 1 inch in diameter, and place them on the prepared baking sheet, spacing them about 2 inches apart.
Flatten each ball slightly with the palm of your hand or the bottom of a glass.
Bake in the preheated oven for 15-20 minutes, or until the edges are lightly golden.
Remove from the oven and allow the shortbread to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
Enjoy your Tropical Pineapple Shortbread with a cup of tea or coffee!
