Here we go. It's super simple.
1 1/2 cups sugar
1 cup butter or margarine (I use Golden Soft)
1/2 Tbl. vanilla (real is best)
1/2 Tbl. butter flavoring
3 1/2 cups flour
Chill until firm - at least 3 hours. I always bake at 325 instead of the typical 350, and I don't set a timer. I take them out when the tops are "dry" to the touch. It's just a thing with me. It works best for my purposes, but if you're more comfortable using a timer, I'd set it for about 6 minutes and then check the tops. I've found that the "until the edges are golden brown" guideline leaves the cookies too hard. I like them on the soft side.
There you go! Let me know if you have any questions. :)
