Pecan Tassies

1/2 cup plus 1 tablespoon butter or margarine
3 ounce cream cheese
1 cup all-purpose flour
1 egg
3/4 cup packed brown sugar
1 teaspoon vanilla
1 dash salt
1/2 cup coarsely chopped pecans

For pastry, beat 1/2 cups butter or margarine with cream cheese. Add flour, beating well. Cover bowl and chill for about 1 hour. In a small mixing bowl, combine egg, brown sugar, 1-tablespoon butter, vanilla, and salt, blending just until smooth. Set egg mixture aside. Shape chilled pastry dough into 2 dozen 1-inch balls. Place each ball in an ungreased 1 3/4-inch muffin cup, pressing the dough onto the bottom and sides of the cup. Spoon about1 teaspoon of pecans into each pastry cup, and fill with egg mixture. Bake at 325 degrees for 25 minutes or until filling is set. Cool on wire racks before removing.
