When ready to assemble nut rolls, preheat oven to 350 degrees. Grease baking sheets.
Sprinkle a flat surface with powdered sugar. Roll out each ball into a circle about 12 inches in diameter. Cut each circle into 12 pizza-like wedges.
Spread each wedge with Nut Filling or any other kind of pastry filling. Roll from wide end to narrow end.
Place on prepared baking sheets and bake in preheated oven for 20 minutes.
Remove immediately from baking sheets and place on wire cooling racks and dust generously with powdered sugar.
Do NOT put in air-tight container. A gift box lined with waxed paper, with the lid on, is ideal as it lets enough air in to keep them from getting soggy. They may also be frozen. Makes about 100 cookies. Enjoy!
