In a large mixing bowl, add egg, butter, cake mix, flour.
Mix until all ingredients are combined.
Chill dough in fridge for about 1-2 hours so that it's easier to handle. It also prevents cookies from spreading too much while baking and they hold their shape better.
Divide the dough into 2 equal portions and roll into balls.
Roll out each ball of dough between two sheets of parchment paper.
Remove the top sheet.
Place your paper template on top of the rolled out dough and use a sharp knife to cut along the edges.
Remove excess dough around the gingerbread man.
Place the entire sheet on a large baking tray. Don't remove the cookie cut out from the parchment paper.
Bake at 350 degrees F for about 15-20 minutes or until the edges are firm and centers are only slightly soft. For these cookies, it's best to over-bake rather than under-bake because this prevents them from breaking later.
Allow the cookies to cool down completely.
Then, gently remove them from parchment paper. Do not try to remove them from the parchment paper before they have completely cool down or else they will break.
Decorate with royal icing or frosting or melted chocolate and candies or anything you desire. Tie a ribbon around its neck, if you like.
Use leftover cookie dough to make smaller cookies with cookie cutters. The bake time for those will obviously be shorter (8-10 minutes). Enjoy!
