Description
This is the cookie version of the fudgy, chocolaty goodness that is a Texas sheet cake. Make sure to frost these cookies while both the cookies, and the frosting, are still warm–because this frosting sets up quickly! Feel free to top these with either chopped walnuts or pecans, if desired. Store in airtight containers.
