I have cookie nip and I've used it a few times. I actually don't care for it. I prefer using the almond flavor.
My friends that I make cookies for love it. My recipe uses a little more flour an no salt. I use between one and two tablespoons of flavoring, the woman who taught me to make sugar cookies told me that people lose their sense of flavor as they age, so in sugar cookies she doubles her vanilla. also use unsalted butter. I read salt can take away the sweetness.
I rarely makes vanilla sugar cookies anymore. I use Julia ushers gingerbread recipe for 3D construction. Everyone loves the flavor and it has minimal spread. It is also very soft. Great recipe! It is made with crisco.
