The only real roadblock to organizing a cookie buffet is narrowing down the options for your guests to choose from. Naturally, any all-American soiree should include traditional chocolate chip cookies, but there are literally hundreds of other selections to choose from. If your party is more down-home than highbrow, consider setting the table with sugar, macadamia nut and peanut butter baked treats. If you really want to earn brownie points from your guests, provide vanilla ice cream for classic ice cream sandwiches.
There are plenty of options to choose from if you'd like a little more style at your dessert table. Any flavor of biscotti, cream-filled sandwich cookies, pecan tassies, fruity pinwheels and macaroons are all popular selections that go well with coffee, wine, Champagne or whatever beverage your guests choose to enjoy.
Be sure to identify the cookies so people with nut or other food allergies can make safe selections.
