Instructions
In a large mixing bowl, cream together the softened unsalted butter and granulated sugar until light and fluffy (about 3-5 minutes). Add the egg yolk and vanilla extract, mixing well.
In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually add to the wet ingredients, mixing until just combined.
Divide the dough into two portions, shape into disks, wrap in plastic wrap, and refrigerate for at least 1 hour.
Preheat the oven to 350°F (175°C) and line baking sheets with parchment paper.
Roll out one disk of dough on a floured surface to about 1/8-inch thickness. Cut out rounds with a cookie cutter and place on baking sheets.
Bake for 10-12 minutes or until edges are lightly golden. Cool on baking sheets for a few minutes before transferring to a wire rack.
Spread dulce de leche on the flat side of one cookie, top with another cookie to create a sandwich. Repeat with remaining cookies.
Dust with powdered sugar before serving. Optionally roll edges in shredded coconut.
