Preheat your oven to 350°F. Start by beating the butter and sugar together until the mixture becomes light and fluffy, which should take about 2-3 minutes with an electric mixer. Then, add the egg and molasses, mixing well until combined.

In a separate bowl, mix together the flour, baking soda, salt, cinnamon, and ginger. Gradually add these dry ingredients to the wet mixture, stirring until everything is well incorporated.

Shape or scoop the dough into balls that are slightly smaller than a golf ball. For an extra touch, you can roll the dough balls in granulated sugar. Arrange them on a baking sheet, spacing them about 2-3 inches apart to allow for spreading.

Bake the cookies for 10-12 minutes. Once done, remove them from the oven and let them cool on the baking sheet for about 10 minutes before transferring them to a wire rack to cool completely.
