Preheat your oven to 350°F (180°C) and line a baking tray with parchment paper.

Cream together ½ cup of softened unsalted butter and 1 cup of granulated sugar until light and fluffy.

Add 1 large egg and 1 teaspoon of vanilla extract, and mix until fully combined.

Whisk together 1 ½ cups of all-purpose flour, ½ teaspoon of baking powder, and ¼ teaspoon of salt in a separate bowl. Gradually add to the wet mixture.

Portion out 2 tablespoons of dough for each cookie, placing them on the prepared baking tray with space.

Press a pineapple ring or chunks into each dough mound and sprinkle a little sugar on top.

Bake for 11-13 minutes until edges are golden and centers are set.

Allow cookies to cool on the tray for 5 minutes before transferring to a wire rack.
