01 - Preheat oven to 350°F. Line two large muffin tins (18 wells) or baking sheets with parchment paper.
02 - Spoon 1 teaspoon melted butter into the bottom of each muffin cup or onto the lined baking sheet, then sprinkle 1 teaspoon brown sugar on top.
03 - Place a halved pineapple ring and a maraschino cherry in the center of each cup or mound.
04 - In a medium bowl, whisk together flour, baking powder, and salt.
05 - In a large bowl, cream the softened butter and granulated sugar until light and fluffy. Beat in the egg and vanilla extract.
06 - Gradually add the dry ingredients to the wet, mixing until just combined.
07 - Scoop about 2 tablespoons of dough, roll into a ball, and flatten slightly. Place each dough disc over the pineapple and cherry, covering them completely.
08 - Bake for 18–20 minutes, or until edges are lightly golden.
09 - Cool in the pan for 5 minutes, then run a knife around the edges and carefully invert onto a wire rack. Let cool completely.
