Combine butter and 1/4 cup powdered sugar until light and fluffy.  Mix in vanilla and rum.

Slowly add the flour, cornstarch, cinnamon, cloves, nutmeg, and salt and combine.

Place the dough onto a piece of parchment paper. Fold the parchment over the dough and roll into a log that is about 1 1/2″ thick. Wrap in parchment.

Place in the freezer for at least an hour  or until firm.

Preheat oven to 350º.

Remove dough from parchment and slice into 1/4″ slices (or if you are a rebel like me, slice it a little wider. Place on lined cookie sheets and bake about 15 minutes.

Let cool about 15 minutes.

Gently toss cookies in remaining 2/3 cup powdered sugar. Brush excess sugar away from cookies and enjoy!
