Drinks like snow top coffee

According to your description, this is not a KFC drink. ...

First, there is no ice cream in the following drinks in KFC;

Secondly, there are many smiling faces on the cup for drinking cool drinks in summer, with the words "Have fun in summer" on it and the logo of KFC in the middle.

You can order another Ding Xue coffee to confirm. Now it's the Xueding caramel macchiato, with caramel concentrate. If stirred evenly, the whole coffee liquid should be caramel sweet. If you don't stir it evenly when you make it or there is caramel precipitation when you take it out, the taste of the liquid should be what you said, sweet first and bitter later.
