Prepare the Dough: In a mixing bowl, cream together the softened butter and cream cheese until smooth. Add the salt and sifted flour, mixing until combined and a dough begins to form.

Shape and Chill the Dough: Shape the dough into a ball, then press down to form a flat disc. Wrap in plastic wrap and refrigerate for 30 minutes.

Roll Out the Dough: Generously flour your countertop. Place the chilled dough on the floured surface and sprinkle a bit more flour on top. Using a rolling pin, roll out the dough to a 10” x 12” rectangle. Lift the dough, add more flour to the surface as needed, then roll it out further to reach a 10” x 30” rectangle.

Add the Jam and Roll: Spread an even layer of jam over the dough, leaving about 1/2 inch bare along one of the shorter edges. Roll the dough up tightly into a 10” log. Chill for another 15 minutes.

Slice and Bake: Preheat your oven to 375°F (190°C). Using sewing thread or dental floss, slice the dough into 1/4-inch rounds. Place each slice flat on a parchment-lined baking sheet.

Bake: Bake for 17-20 minutes, or until the edges are golden. Transfer cookies to a wire rack to cool completely.

Decorate: Once cooled, sprinkle powdered sugar over the top for a festive, snowy finish.
