Can I use raw sugar to make cookies instead of granulated? I am currently outside of the United States and I haven't been able to find granulated sugar, all I've been able to find is what seems to be raw sugar and powdered sugar. Would either of these work to make chocolate chip/sugar cookies?
Granulated sugar is 100% sucrose with the molasses removed. Raw sugar on the other hand is refined sucrose with its natural molasses. The answer is yes, you can use them but you might need a bit of tweaking within the recipe. If your raw sugar looks a bit more like brown sugar then your chocolate chip cookies would come out more chewy (not that its a bad thing) because of the molasses in them, whereas granulated sugar would yield a crumb that is more crisp. 

P.S. Its alright to use powdered sugar. Some recipes even call for it when baking cookies. However, when substituting granulated sugar to powdered sugar, i recommend that you use a scale since powdered sugar holds so much air when packing into a cup measurement. Measure 7 oz of powdered sugar per 1 cup of granulated sugar.
