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

Cream together softened unsalted butter and granulated sugar until light and fluffy.

Add one large egg and vanilla extract to the mixture and blend until combined.

Whisk together all-purpose flour, baking soda, and salt in a separate bowl.

Gradually add the dry mixture to your wet ingredients, stirring until a soft dough forms.

Scoop out 2 tablespoons of dough for each cookie and place them on the prepared trays.

Press a pineapple ring into the center of each cookie and sprinkle additional sugar on top.

Bake for 11 to 13 minutes until edges are golden brown; allow to cool for a few minutes before transferring to a wire rack.
