Pyure is a stevia and erythritol blend that does not cause a spike in blood sugar like sugar does. The ingredients are natural substances and a wonderful replacement for sugar without the aftertaste of stevia. Truvia can work as well. I find mine at Wal-Mart You can use regular chocolate chips if you rather, it just wouldn't be completely sugar-free, it would though still have way less sugar than normal. Coconut flour will give the cookies a subtle coconut flavor, but it wasn't bad to me who dislikes coconut a lot. It is also a very thirsty flour so add in water or almond milk to get to a good consistency, it is ok to be a little crumbly as dough. It doesn't taste dry with the cheesecake on it.
