Glazed Peanut Butter Bars

Ingredients:
1 cup peanut butter, crunchy or smooth
2/3 cup butter or margarine, softened
1 teaspoon vanilla extract
2 cups firmly packed light brown sugar (push through a sieve to remove any lumps)
3 eggs
1 cup all-purpose flour
1/2 teaspoon salt
3/4 cup powdered sugar
2 teaspoons water
2 squares semi-sweet chocolate OR 1/4 cup semi-sweet chocolate pieces + 1 teaspoon shortening, melted

Directions:
First: Combine peanut butter and butter in a large bowl and beat until light and fluffy. Add brown sugar and continue to beat for 1-2 minutes. Beat in eggs one at a time then add vanilla.
Second: Stir in flour and salt just until well blended; spread batter in greased or foil lined 13×9 inch baking pan.
Third: Bake in 350-degree oven for 35 minutes, or until center springs back when lightly touched with fingertip. Allow to cool slightly.
Fourth: Combine powdered sugar with water in a small bowl and stir until smooth. Drizzle from a spoon over still-warm cookies in pan; Swirl with a spoon to make random pattern.
Fifth: Melt chocolate in a small zippered, plastic bag for one minute in microwave. Knead with fingers to make sure it is melted. Return to microwave for a few additional seconds if necessary. Chips may take a little longer. Snip a small tip from one corner and drizzle over the white glaze in a random black and white pattern. When cool, use a sharp knife to cut into 36 rectangles.
