In a large bowl, beat butter, sugar, dry pudding mix and egg in a large bowl until well blended.

In a separate bowl, mix together remaining ingredients Slowly add ingredients from secondary bowl to the butter mixture. Refrigerate for at least one hour or until dough is firm.

Preheat oven to 350 F. Roll dough out on a floured work surface to 1/4-1/2-inch thick. Use cookie cutters to shape cookies. Place cookies on a parchment lined cookie sheet. Bake 10-15 min. or until edges are lightly brown.

To prepare glaze: Combine the white chocolate chips and shortening in a microwave safe bowl. Heat in the microwave, 10 seconds at a time, stirring between every heating. For me this took about 40 seconds overall, but microwaves vary. If the chocolate gets hard or has a very strange texture, it has gotten too hot and seized. If this happens, you will need to start over.
