Sometimes a classic is so simple that when you taste it, you know it’s PERFECT. Nick Malgieri developed this cookie at the New York Restaurant School in 1981 when we worked together. The students ran a restaurant and served petits-fours at the end of meals. I personally polished off way too many of them, and even came to work early to gobble one or two left from the previous day while I had my first cup of coffee. They are melt-in-your-mouth terrific. With his permission, I share the recipe here and in my cookbook. Thanks, Nick.
