Add butter, sugar, molasses, and egg to the bowl of an electric mixer
Beat well at medium-high speed until light and fluffy
In a separate bowl, combine flour with remaining dry ingredients
Add flour mixture to butter mixture and mix until just blended
Chill dough, covered with plastic wrap, for at least one hour.
If you are not using parchment paper or a silicone sheet, then grease your cookie sheets.
Pour extra granulated sugar in a medium bowl.
Form 1" dough balls and roll in granulated sugar. I like using a 1 Tbsp cookie scoop to form the cookies.
Place 1" apart on prepared baking sheets, parchment paper, or Silpat.
Heat oven to 375°F and bake 8-10 minutes until set.
Let cool on cookie sheet for 5 minutes, and then transfer to a wire rack to cool.
Once cool, store in an airtight container.
