Preheat the oven to 175°C. Prepare a mini round cake pan or similar cavity-style baking tin.
02 -
In a large bowl, beat together the room temperature butter and granulated sugar until light and fluffy.
03 -
Add eggs, vanilla extract, and sour cream. Mix until fully incorporated.
04 -
Add flour, baking powder, cornstarch, and salt. Mix just until a cohesive dough forms. Do not overmix.
05 -
In a separate bowl, combine the melted butter and light brown sugar, stirring until smooth.
06 -
Spoon approximately 1 tablespoon of the brown sugar mixture into the base of each cake pan cavity. Spread evenly.
07 -
Place one pineapple slice over the brown sugar mixture, then center a maraschino cherry within the pineapple ring.
08 -
Scoop about 3 tablespoons of cookie dough onto each pineapple-cherry assembly. Flatten the dough gently to cover the fruit and fill the cavity using an offset spatula.
09 -
Bake in the preheated oven for 25 minutes, or until the edges turn golden and the brown sugar mixture bubbles around the sides.
10 -
Let the cookies cool in the pan for 10 minutes. Invert onto a wax paper-lined surface, allowing excess caramel to run off. If pineapple slices stick, reposition on the cookies.

Allow cookies to cool completely before serving. Store the cookies in an airtight container and consume within 2 to 3 days for optimal texture.
