Remove the dough from the refrigerator. If the dough has been in the refrigerator for more than 4 hours, then leave it on the work surface for 10-15 minutes so that it warms up. Roll out the dough into a layer 0.5-0.7 mm thick. Cut out the cookies using a cookie cutter (the size of a large heart is 9×9 cm), set aside half of the cookies, and in the second half of the cookies cut out smaller hearts (4.5×4.5 cm). Collect the remaining dough, roll out and cut out a few more cookies.
