In a large bowl, beat softened butter and sugar until light and creamy.

Add egg yolks and vanilla extract, mixing until fully combined.

In a separate bowl, mix all-purpose flour, almond flour, and salt. Gradually add the dry ingredients to the wet mixture, forming a soft dough.

Divide the dough into two portions, flatten each into a disk, wrap in plastic wrap, and refrigerate for at least 1 hour.

Roll out one dough disk to ⅛-inch thickness on a floured surface. Cut out shapes with a cookie cutter and transfer to a parchment-lined baking sheet.

Roll out the second dough disk and cut the same shapes, but with smaller cutouts in the center.

Preheat oven to 350°F (175°C) and bake the cookies for 8–10 minutes or until edges are golden.

Let the cookies cool completely on a wire rack.

Spread a thin layer of warmed jam on the flat side of each whole cookie.

Place a cutout cookie on top to make a sandwich.

Dust the cookies with powdered sugar before serving. Enjoy!
