I've had this cookie mix sitting on the shelf for a while, and I was glad for an opportunity to try them out. I made the chocolate chocolate chip cookies over the summer, and we enjoyed them, so I had high expectations that weren't disappointed.
The additional ingredients are butter, an egg, and vanilla. I like that it also gave instructions for oil - I've been caught low on butter before - and it makes them gluten-free and dairy-free.
I had to use my hand to get the ingredients well-blended. Butter is that way sometimes. But over all this was easy to do and I would recommend this product for a nice treat.
