12 Oreo Cotton Candy Cookies. Our delicious Oreo Cotton Candy cookies can be made in rainbow colors, all white or a mix of pink and blue for gender reveal parties. Made to order so they are always fresh. Each cookie is approximately 3" round and individually packaged. Cotton candy is heat sensitive so you must be home the day of delivery. Store in a cool room away from heat/sunlight or refrigerate until the day of the party. Please put your party date in the notes so we know when to ship your order.
