Scrape sides of bowl and transfer the dough onto a floured surface. If dough is too soft, chill until easier to handle. With a floured rolling pin, roll the dough out to a G-inch thickness. Or, roll between two sheets of waxed paper. With a cookie cutter, make 2-inch diameter rounds.
Place rounds on a cookie sheet.
Bake for 10 minutes or until pale golden-brown. Let cookies cool. Make cookie sandwiches using dulce de leche as a filling. Sift a generous amount of powdered sugar on top of alfajores. Makes about 16.
