Preheat oven to 350F. Line a baking sheet with parchment paper.
In a medium bowl, whisk together flour, baking soda, salt and spices.
In a large bowl, whisk together sugar and olive oil until well-blended. Beat in egg, molasses and vanilla extract. Stir in flour mixture until no streaks of flour remain.
Shape dough into 1 inch balls, roll in sugar and place on baking sheet, allowing about 2-inches between cookies to allow for spread. The cookies do not need to be flattened.
Bake for about 7-9 minutes until the outside edge of the cookies are just set and are very lightly browned. Do not overbake.
Let cookies cool for 3-5 minutes on cookie sheet, then transfer them to a wire rack to cool completely.
Makes about 3 dozen.
