I have bought the cookie cremes also in the mint flavor and my daughter has not reacted to them (at least not in any dramatic way). I believe there is no kosher marking at all on the package, and I remember calling Hain (the manufacturer) and they assured me there was no dairy in them and no cross contamination. I think they said that although their products are not kosher marked, they always put an allergy warning on any products that could potentially be cross contaminated with ingredients like milk and nuts.
