Cream shortening, peanut butter and brown sugar until well combined and fluffy. Add milk, vanilla and egg. Mix just until combined.
In a separate bowl, mix flour, salt and baking soda. Add to the creamed mixture and stir to combine.
Drop by heaping teaspoonfuls 2 inches apart on an ungreased cookie sheet. Dip a fork in sugar and press lightly twice on one cookie, flattening it slightly to create a crisscross pattern. Repeat for each cookie.
Bake for 7-8 minutes until set and just beginning to brown on the edges. Do not overbake, as cookies will continue to cook on the hot cookie sheet after removing them from the oven.
Allow cookies to rest on the cookie sheet for 2 minutes and then remove to a cooling rack.
Yield: 3 dozen cookies
Hack: Store cookies in a tightly sealed container at room temperature for up to 5 days.
Hack: Cookies can be frozen for up to 3 months. Place cookies on a cookie sheet lined with parchment paper and place them in the freezer until completely frozen. Remove to a sealable freezer bag and place in a freezer-safe container. To thaw, remove the desired number of cookies from the bag and place them on a paper towel-lined plate. Allow to thaw completely before serving.
