1/3 cup butter
1/3 cup firmly packed brown sugar
1 cup all-purpose flour
1/2 cup finely chopped walnuts or pecans
1/4 cup sugar
8 oz. cream cheese, softened (Low-fat cream cheese is fine in my opinion. But if you don't usually like it, stick with the regular)
1/2 tsp vanilla
2 Tbsp milk
1 Tbsp lemon juice
Heat oven to 350. In a small bowl, cream butter and brown sugar until light and fluffy. Lightly spoon flour into measuring cup; level off. Combine flour and walnuts or pecans with creamed mixture. Reserve 1 cup for topping. Press remainder into bottom of ungreased 8" or 9" square pan. Bake for 9-11 minutes or until lightly browned.
In a small bowl, blend sugar and cream cheese until smooth (if using fat-free cream cheese, mixture will be kind of lumpy, but it will cook up just fine). Add milk, lemon juice, vanilla, and egg. Beat well. Spread over baked crust. Sprinkle with reserved crumb mixture. Bake at 350 for 23-27 minutes or until lightly browned. Cool. Cut into bars. Store in refrigerator. Makes 24 small bars.
