1 1/3 cups all-purpose flour
3/4 cup coarsely ground walnuts
1/2 scant cup granulated sugar
3/4 cup butter or margarine
1/2 teaspoon vanilla extract
2 (1 ounce) squares semisweet chocolate

Combine flour, walnuts and sugar. Cut in butter until mixture is crumbly. Quickly stir in vanilla extract and chocolate, being careful not to cream the mixture. Press mixture into a 9-inch round cake pan.

Bake at 350 degrees F for about 50 minutes. Cool.

Break into pieces and serve.

This is good served with vanilla ice cream and espresso coffee, if desired.
