Preheat your oven to 375 Fahrenheit.

Mix the shortening, peanut butter, brown sugar, egg, milk and vanilla in a large mixing bowl with a hand held mixer. Just mix until all the ingredients are combined. Do not over mix.

In a separate bowl, combine the flour, cocoa, salt and baking soda.

Then gradually stir in the flour mixture into the wet mixture by hand. The dough will be thick.

Use a cookie scoop to drop about 1 tablespoon of the cookie mixture onto an ungreased cookie sheet.

Then make the crisscross design on the top of each cookies with a fork.

Bake for approximately 7-8 minutes until the cookies are firm. Cool on the cookie sheets for a few minutes and then move them to a wire rack to cool completely.
