Mini Kiss Blondie Bars

1/2 cup butter or margarine, softened
1/2 cup shortening
1 cup packed light brown sugar
1/2 cup granulated sugar
2 eggs
1 teaspoon vanilla extract
1/2 teaspoon baking soda
2 1/2 cups all-purpose flour
1 3/4 cups (10 ounce package) Hershey's
    Mini Kisses, Milk Chocolate, divided
1 cup chopped nuts

Heat oven to 375 degrees F.

Beat butter and shortening in large bowl on medium speed of mixer just until blended. Add brown sugar and granulated sugar; beat well. Beat in eggs, vanilla extract and baking soda. Gradually beat in flour (if dough becomes too stiff, stir in remaining flour with spoon). Set aside 1/2 cup Mini Kisses; stir in remaining Kisses and nuts. Press dough into ungreased 15 x 10-inch jellyroll pan (dough will be stiff). Bake 15 to 20 minutes or until top is golden.

Remove from oven; immediately place reserved Kisses over top, pressing down lightly. Cool completely in pan on wire rack. Cut into bars.
