In a large bowl, cream together the butter and granulated sugar until light and fluffy. Add eggs, vanilla extract, and sour cream. Mix until combined.

In a separate bowl, whisk together flour, baking powder, cornstarch, and salt. Gradually add the dry ingredients to the wet mixture until just combined. Set aside.

In another bowl, stir together the melted butter and brown sugar until smooth.

Add about 1 tablespoon of the brown sugar mixture to the bottom of each cavity of the pan, spreading it evenly. Place one pineapple slice over the brown sugar mixture and a maraschino cherry in the center of each pineapple slice. Using a 3-tablespoon scoop, add cookie dough on top of the pineapple and flatten slightly with an offset spatula.

Bake for 25 minutes, or until edges are golden and the brown sugar is bubbling up the sides.

Let cool for 10 minutes, then carefully invert onto wax paper (the brown sugar glaze will run). Allow to cool completely before serving.
