In a large bowl, mix together melted butter, 1 cup sugar, and egg.
Mix in the molasses. Do not over-mix.
Combine dry ingredients in a separate bowl.
Slowly add dry ingredients to wet ingredients.
Cover and chill dough for at least 2 hours.
Preheat oven to 375.
Roll dough into golf ball sized balls.
Roll them in the remaining sugar.
Place cookies 2 inches apart onto ungreased cookie sheet. A darker cookie sheet will work best.
Press on the cookies to flatten them out slightly.
Bake 8-10 minutes, or until the tops are slightly cracked.
Cool on a wire rack if you have one (or just take them off the pan fairly quickly after they come out of the oven).
Note: Depending on the cookie sheet you use, the bottoms will sometimes burn. Prevent this by placing the cookie sheet on the top rack, or putting parchment paper on the cookie sheet before the cookies.
