1/2 cup shortening
1 cup white sugar
1 cup milk
2 eggs
1 teaspoon vanilla extract
1 (15 ounce) can marshmallow creme
1/4 cup light rum
1/2 cup water
1 1/2 cups all-purpose flour
1 teaspoon baking powder
1/2 teaspoon salt
1 cup chopped walnuts
Preheat oven to 350 degrees F (175 degrees C). Grease cookie sheets.
In a large bowl, cream together the shortening and white sugar until smooth. Beat in the milk, eggs and vanilla until a soft dough is formed. Mix in the marshmallow creme, rum, water and flour. Roll dough into 1 inch balls and place them 2 inches apart onto the cookie sheet.
Bake for 10 to 12 minutes in the preheated oven, until lightly browned. Allow to cool completely before cutting into squares.
