Raisin cookie is great to bake and serve fresh in the winter months. Raisin cookies are made with raisins that are embedded in the cookie after it is baked. Both flour and oatmeal are popular as the base for the batter for raisin cookies. Raisins are often paired with nuts in the cookies to pack an extra crunch. Raisin cookies may or may not be frosted with sugar. Some variations of the raisin cookies use cinnamon to flavor the cookie.
