Let butter get to room temperature.
Cream butter and sugar together. Add
unbeaten egg and vanilla and mix until smooth. Sift dry ingredient and add to
mix. Divide into thirds refrigerate until firm. Roll out and cut. You can roll into
a log, wrap with waxed paper and refrigerate.
Preheat 350 degrees. Bake until
lightly brown. Do not overcook. These are delicate and melt in your mouth.
