"Now you see & Now you don't" Cookies

I made Chocolate Chips Cookies for my husband's collegues. All the varieties...Normal Chocolate Chips Cookies, Chocolate Chips with Hazelnuts cookies & Chocolate Chips Oats cookies. Until one day, the boss, Hasrin, requested Chocolate Chips with Nestum cookies.It was a hit! Everyone likes them, even my kids love them. At home,a full container will be empty by the end of the day...." Now you see them & now you don't"
