Preheat oven to 350*F. Line cookie sheet with Parchment paper & set aside. In large mixing bowl beat butter for 30 seconds until fluffy. Add Brown sugar, spice, & salt. Beat til combined, scraping sides when necessary. Using a wooden spoon, mix in flour. (I ended up using hands to mix in last of flour..trying not handle to much)

Dip bottom of glass or cookie stamp into granulated sugar (I mixed 1 tsp of spice with 1/4 cup of sugar for this part.) And Flatten Cookie.
