Preheat the oven to 350°F (175°C).

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

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

Beat in the egg and vanilla extract until well combined.

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

If using, fold in the chocolate chips.

Drop spoonfuls of dough onto a baking sheet lined with parchment paper.

Bake for 10-12 minutes, or until the edges are golden brown.

Allow cookies to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
