1 chocolate cake mix
3/4 cup shortening
6 oz chocolate chips (half a bag)
1/2 teaspoon peppermint extract
Mix together. Bake at 350 degrees for 9 - 12 minutes, until cookies look slightly under done. Then let finish baking on cookie sheet. These cookies will be slightly crunchy. If you prefer soft cookies, after the cookies have cooled, put them in a plastic bag with a slice of bread overnight, and they will get nice and soft.
Note: if you use a cookie scoop, you will want to break the dough balls in half so they won't take too long to cook. Also, cookies baked with Crisco seem to take longer than cookies using a generic brand.
