A favorite cookie of mine at Christmas is Tingalings. Super easy to make, although you need some space in the frig to chill them. Here's the recipe.
Melt 12 oz semisweet chocolate chips (2 cups or small package). I do this in the microwave a minute or two at a time. Note that it's important to take out and stir, as the top can look as if they are not melted when they actually are, and you do *not* want to burn the chocolate! Using a very big bowl because it gets messy, stir in 4 cups of Wheaties. Drop by the tablespoonful onto waxed-paper lined cookie sheets. Chill in refrigerator for 2 hours or in freezer for less time. You can substitute other types of chips and other types of wheat flakes, but this is my personal favorite.
These are delicious, look good, last a long time in tins, and are fun for kids to make.
