This recipe came with my cookie press and I am posting it here for safe keeping. The dough works particularly well with the press, and makes well-formed cookies.
Combine the butter and sugar in a large bowl. Using an electric mixer set on medium speed, beat until light and fluffy.
Beat in the egg, vanilla extract, cardamom (if using), and salt. Using a spoon, stir in the flour until well mixed.
Pack the dough into a cookie press. Fit the press with the desired disk, and press the dough out onto an ungreased cookie sheet, spacing the cookies 1 inch apart.
Bake until lightly golden, about 10 to 12 minutes. Gently transfer the cookies to wire racks to cool. Sprinkle with vanilla sugar, if desired, or decorate with icing.
