Add cookie mix to a large bowl.

Stir in pumpkin pie spice, ginger and cinnamon and mix well.

Add butter, egg and vanilla and work dough with the back of a spoon. The dough will seem dry and crumbly. Continue to work it until a dough forms.

Cover and refrigerate for 30 minutes.

Preheat oven to 350 and line a baking sheet with parchment paper.

Use a tablespoon portion scoop to scoop dough into the palm of your hand and roll into 32 balls.

Place the balls on baking sheet 2" apart.

Bake for 8-11 minutes or until set. Let set on cookie sheet for 1 minute before moving to a cooling rack to cool completely.

Once cookies are cool, add a dollop of frosting and top with another cookie. Repeat until all cookies are turned into sandwiches.
