Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.

In a large mixing bowl, whisk together flour, baking soda, ginger, and cinnamon.

In another bowl, cream together butter, brown sugar, and granulated sugar until light and fluffy.

Beat in egg and molasses until fully incorporated.

Gradually add the dry mixture to the wet mixture, stirring gently until just combined.

Drop rounded balls of dough onto prepared baking sheet and bake for 8-10 minutes.

Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack.
