How to make chewy chocolate chip cookies
Preheat the oven to 350f/180c.
Add the vanilla, sugar, brown sugar, eggs, and butter to a bowl.
Use coarser sugar for thicker, chewier cookies. When sugar dissolves, it acts as a tenderizer that interferes with dough structure.

Choices:
(A). Sugar replacement works best with non-concentrated, non-starchy pastry that is not fried. Add the flour to a mixing bowl.;
(B). It gives your dough more body and adds flavor. Mix the dry ingredients in a separate bowl.;
(C). This increases spreading because finer sugar dissolves more easily than coarser sugar. So if you want your cookies to remain thick and chewy, use coarse sugar (or use fine sugar for the opposite effect).;
(D). Baking the cookies lightly in the oven causes them to become sticky and make them chewy. Sift the flour and baking powder in a separate bowl.;. The answer should be
(C).
