Since the butter is hot, it’s important to make the batter ahead of time, chilling for at least 30 minutes (or up to a week) before baking.
* If using M&M’s, cook the batter for 5 minutes then add M&Ms (using a pot holder!) Continue baking until golden brown. About 11 minutes.
* If drizzling with chocolate, pour about 1 cup of chocolate chips into a microwave safe bowl. Zap for 30 seconds at a time, up to 2 minutes, until melted. Either scoop into a piping bag, or simply fill a spoon with chocolate and carefully zigzag over one side of each cookie. Sprinkle. Allow to set before serving.
* If using a specialty Christmas cookie pan, fill with one scoop of batter and bake for 10-11 minutes. Allow to cool for 3-5 minutes before removing from pan.
