Melt chocolate in large bowl set over pot of simmering water, stirring frequently until smooth. Remove bowl from the heat. Dip cookies, one at a time, in melted chocolate. (If chocolate begins to harden before you've finished dipping the cookies, return the bowl to the double boiler.) Place dipped cookies back on the parchment-lined baking sheet. If desired, drizzle some of the melted chocolate over the top of each cookie. Once all the cookies have been dipped, chill for 20 minutes. Store cookies in airtight container at room temperature for up to 1 week.
