Line a cookie sheet with parchment paper. Set aside.

In a medium bowl, whisk together the flour, baking powder, salt, cinnamon, and nutmeg. Set aside.

In a large bowl, with an electric mixer, cream together the butter, white sugar and brown sugar.

Add the eggnog, egg, and rum extract beating until smooth.

Add the flour mixture and stir until just combined.

Fold in the white chocolate chips.

Use a cookie scoop to scoop tablespoonful of the dough and place them on the prepared cookie sheet 1 inch apart.

Chill in the refrigerator for 20 minutes.

Heat the oven to 350F and bake for 15-18 minutes, until edges of the cookies are just beginning to brown.

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