Combine the cookie dough and all-purpose flour using a stand mixer.
Roll out the dough between two sheets of parchment until it is about 1/4-inch thick.
Cut the shape of a Christmas tree and transfer the tree to a baking sheet. Combine the remaining scraps of dough and roll out to the same thickness as before. Cut the rolled scraps with assorted cookie cutters, these will be used as ornaments to decorate your tree. Place on a separate baking sheet. Bake the tree for 16 to 18 minutes and the smaller decorations for 12 minutes. Let cool completely and decorate as you wish.
