* If needed, please refer to Baking Conversion Charts.
In a large bowl with a handheld mixer or stand mixer with the paddle attachment, place softened butter and whip, gradually adding powdered (icing) sugar. Add scraped seeds of vanilla bean, lemon zest, salt and continue to whip until light and fluffy (about 10 minutes).
In a separate bowl, beat egg yolks with milk, using a fork. In another bowl, sift half of the flour, using a flour sifter. Add egg yolks/milk mixture to the principal preparation, alternating with flour, and beat until well-combined after each addition.
Sift the remaining flour with baking powder and combine with a rubber spatula, working from bottom to top.
Transfer the cookie batter into a pastry bag with an open star pastry tip and pipe rings onto a baking sheet covered with parchment. Sprinkle cookies with nuts, chocolate chips, or leave them plain. Refrigerate the cookie sheet for about 30 minutes.
Preheat oven to 350 F/175 C. Bake cookies for about 13 to 15 minutes, until the cookie edges are lightly browned. Remove from the oven and allow cookies to cool completely on the baking sheet. Sprinkle cookies with powdered (icing) sugar if you desire.
