Preheat oven to 350 degrees F.
Combine the cookie mix with the cream cheese until crumbly. Mix in the eggs and flavoring until well combined. Add enough flour to make a firm dough that can be rolled out. Roll dough out on lightly floured board to 1/4-inch thickness. Cut out snow flakes, doves, or other desired shapes.
Place on ungreased baking sheet and bake for about 8 minutes.
While the cookies are baking, make the icing by combining powdered sugar and meringue powder. Add 1 teaspoon of water at a time until it reaches desired consistency.
Decorate cookies with royal icing. Allow to dry for 1 hour.
To make the cookies into ornaments, use a toothpick or chopstick to form a hole in the dough at the top of the design before baking. Make the hole large enough to be sure it doesn't close up during baking. Remember to clear the hole before icing hardens.
