Last year, I received a very last-minute email for an upcoming Christmas class party for one of my kids.
Usually we're notified weeks in advance of a class party and parents are either assigned something for the child to take to the party, or they sign up for a certain dish (main dish, dessert, etc.).
Despite the last-minute notice, I still wanted to make something, so I decided to just use whatever I had on hand - OREOs, sprinkles, candy canes, and almond bark. The result was chocolate-dipped OREOs covered in crushed candy canes and sprinkles.
The best part is that kids can help decorate! They'll love dipping the OREOs in chocolate and throwing on the crushed candy canes and sprinkles.
