I searched quite a bit online for vegan chocolate chips that are white, vegan and keto without much luck, so I used this brand of vegan white chocolate chips that has less sugar but is not really keto. I managed to contain the carbs to 4 net grams per cookie, however. Evolved has a vegan white chocolate bar that is dairy-free and keto. I haven't tried it and I don't know if it is suitable for baking, but I assume you could break it into pieces and use it in the cookies. If you are not vegan or dairy free you can use white chocolate chips from Lily's. I use their dark chocolate chips, which are vegan, in my keto baking).
