While ice bound the other day I experimented with the old standard tollhouse recipe that is on the back of the chocolate chip bag and came up with a basic chocolate drop cookie that you can add anything to. By increasing the brown sugar from 3/4 cup to 1 full cup and by adding a 1/2 cup of baking cocoa you get a chocolate drop cookie. The I split the dough in half. In one half I added mint chocolate chips, YUMMY! and in the other half I added heath bar crunchy stuff that you can buy in the bag just like choc chips. They were awesome too.
