Cream together butter and sugar. Mix in vanilla and cornstarch, then add flour gradually. When combined (it probably won’t hold into a ball yet), mix in orange zest and cranberries. Knead a couple times if needed.
Roll dough into a log. To create a smooth log, I used a rolling motion like when kids make play dough snakes. Wrap the log with waxed paper and refrigerate at least an hour.
After the dough is chilled, cut into approximately ¼ inch slices. If you’d like to decorate the cookies with nuts or sugar, do so now.
Set cookies on ungreased cookies sheet allowing for some spread.
Bake at 350 F for 12-15 minutes. Cookies are done when they are just starting to brown on the edges.
