Melt-in-your-mouth Peanut Butter Cookies

In a mixing bowl, cream together butter (margarine), shortening, peanut butter, and vanilla. When all blended, add sugar and cream well.

In a small bowl, mix together: flour, baking soda, and salt. Add alternately with water to creamed mixture.

Form dough (about 1 tsp) into balls and place on ungreased cookie sheet.
Flatten in a criss-cross pattern with a fork. (If you dip fork into Splenda first it will help to avoid sticking).

Bake at 350° for 15-18 minutes. Let cookies cool slightly on pan before moving to cooling rack.

Makes about 3-4 dozen.
