ISO: Cake Mix Cookies with Lemon or Orange?

Over the holidays, up north, we visited with friends and she had a plate of Christmas cookies out. One of them was a white, soft drop cookie, glazed with holiday sprinkles on them. The flavor was very lemony or maybe even some orange, too, and it was very rich - they almost tasted like they had sour cream or cream cheese in them.

Would anyone have the ingredients for this - I asked the friend for the recipe, but she said they had come from another friend, and she'd try to get it, but --- maybe someone here can help out. I would say that it was made with a white cake mix not yellow, but with the citrus flavors.

Thanks in advance.
