In a mixing bowl, whisk together the flour, baking soda, ginger, cinnamon, nutmeg, and salt.

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

Beat in the egg and molasses until well combined.

Gradually add the dry ingredients to the wet mixture, mixing until just combined.

Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.

Using a cookie scoop, form the dough into 1-inch balls and place them on the prepared baking sheet.

Bake for 12-15 minutes until the edges are set but the centers are still soft.

Remove from the oven and let cool on the baking sheet for 5 minutes before transferring to a cooling rack.

While the cookies are still warm, roll them in powdered sugar until fully coated.

Allow the cookies to cool completely before serving.
