01 - Preheat oven to 350°F. Line two large baking sheets with parchment paper.
02 - In a small bowl, combine melted butter and brown sugar until smooth.
03 - Place a teaspoon of the butter-sugar mixture in the center of each parchment-lined cookie spot (18 spots total, spaced apart).
04 - Arrange a few pineapple pieces and half a cherry over each butter-sugar mound, pressing gently to adhere.
05 - In a medium bowl, whisk together flour, baking powder, and salt until evenly blended.
06 - In a large bowl, beat softened butter and granulated sugar until light and fluffy, about 2-3 minutes. Add egg and vanilla; beat until fully combined.
07 - Gradually add the dry ingredients to the wet mixture, mixing just until a soft dough forms. Be careful not to overmix.
08 - Scoop 2-tablespoon portions of dough and flatten into thick discs. Place each disc over the pineapple-cherry topping, fully covering the fruit.
09 - Bake for 13-15 minutes, until edges are lightly golden and centers are set.
10 - Let cool on the sheet for 3 minutes, then carefully invert each cookie onto a wire rack while still warm to reveal the caramelized fruit topping.
11 - Cool completely before serving to allow flavors to set.
