For cookies, preheat oven to 350 degrees. In a large bowl, cream
first 4 ingredients until fluffy. Add eggs and vanilla; beat until
smooth. Stir in peanut butter. In another large bowl, stir together
flour and salt. Add dry ingredients to creamed mixture; stir until a
soft dough forms. On a lightly floured surface, use a floured rolling
pin to roll out dough to 1/4" inch thickness. Use a 3 inch round
cookie cutter to cut out cookies. Transfer to a greased baking sheet.
Bake 10-12 minutes or until golden brown. Transfer to a wire rack
with waxed paper underneath to cool completely. For icing, stir
together sugar and milk in a small bowl until smooth. Ice cookies.
Allow icing to harden. Use a small round tip to pipe red icing on
cookies to resemble stitching on baseballs. Allow icing to harden.
Store in an airtight container. Makes about 5 dozen cookies.
