If you do not have a piping bag or large open star tip, you can put the dough into a plastic bag and press the dough into the corner. Then, cut the bag's tip and pipe the cookies onto the parchment paper. Another alternative is to use a cookie press or cookie scoop. Or, just use a smaller size spoon and make the cookies round. Depending on your method and the piping tip size, you may get more or fewer cookies than noted in the recipe.
