A choco pie is a very yummy treat! It's like a little cake with a soft filling inside and covered in chocolate. Imagine a round cookie with marshmallow in the middle, then it's covered in chocolate like you would put on ice cream. It's kind of like a sandwich, but instead of bread or cheese, it's all sweet and delicious. People all over the world love choco pies because they're so tasty and they make us happy!
