Ice Cream Cookies

This is going back...way back...old school.

Ice Cream Cookies

     1 lb butter, softened
     2 c sugar
     1 tbsp vanilla
     1 egg
     5 c flour

Preheat oven to 350 degrees.  Cream butter and sugar together.  Add vanilla and egg.  Add flour, one cup at a time, until all incorporated.  Using a #60 disher (a little less than a tablespoon), scoop dough onto ungreased cookie sheet (a flat cookie sheet can accommodate 20-23 cookies).  Flatten to 1/4" thickness with the bottom of a drinking glass (use parchment paper between dough and glass).  Bake for 13 minutes, rotating cookie sheet once.  Remove to a cooling rack to cool completely before storing in an airtight container.  For slightly larger cookies, use a #50 disher and bake for 15 minutes, rotating cookie sheet once.
