Preheat your oven to 350 degrees. Prepare your cookie sheet by either spraying with cooking spray or line with parchment paper.
In a large bowl, cream butter and sugars until light and fluffy. Beat in the egg and sorghum. Add the spices, baking soda, and salt until combined. Add the flour and mix well.
Shape into 2-inch balls and roll in the sugar. Place 2 1/2 inches apart on the cookie sheets. Press the cookies down with a fork in opposite directions (like a peanut butter cookie). Bake for 12 minutes or until the tops are cracked. Remove to wire racks to cool.
