Chick-fil-A describes an average Icedream cone as a "delicious, frozen dairy treat with an old-fashioned vanilla taste" — very similar to everyday vanilla soft serve. However, technically speaking, Chick-fil-A's soft serve isn't exactly soft serve or even ice cream.

Regular ice cream and Icedream are both made up of cream, sugar, and milk, but Icedream lacks the butterfat that can be found in other ice cream varieties. According to the United States Department of Agriculture, ice cream must have at least 10% butterfat, and Chick-fil-A's Icedream is said to have only 3% butterfat.

The lower butterfat content is because an Icedream cone has more air in it than a regular serving of vanilla soft serve, meaning there's not as much room for butterfat as there is in regular ice cream. While Chick-fil-A hasn't released an official recipe regarding how it's made, one former employee speculated on Reddit that the treat contains eggs.
