Best sugar cookie recipe ever! Same recipe my grandmother taught me when I was nine years old, which was 65 years ago. My cousin and I used it with our children and now grandchildren. Still teaching it to my younger (ages 9 & 11) grandchildren yesterday, who raved over how delicious. I have always use shortening, but I will try butter next time. I only sift once then measure. If dough is too sticky, I add a tiny bit more flour. Chilled dough 2 hours or overnight, then got out and closer to room temp, until malleable. I baked 7 to 8 minutes, not nine.
