I wanted to let you know that the folks at Bumbalooza have responded and clarified. The printing on the side of the package of the Cookies and Cream mix that I received was an error. All of the products that Bumbalooza makes are dairy-free except for the Cookies and Cream mix. The ingredient list was accurate. The label on the side has been corrected.
As a reminder, if you aren't allergic to dairy, the Cookies and Cream muffins that I made were quite tasty!
