Austen Family Cooks/Recipe:Walnut Squares

Walnut Squares are rich. They are decadent. They are not singular but, rather, plural: one is never enough. Even with a reservoir of amazing desserts at our finger-tips, this is on everybody's favourites list. They are best paired with a cup of coffee or, in my case, tea.
Be careful who you share this recipe with: once tasted, people cannot get enough. You will be pestered for the recipe or, most likely, asked to make it at every gathering.

WALNUT SQUARES

PART I:

1 CUP FLOUR
1/4 CUP BROWN SUGAR
1/2 CUP SOFTENED MARGARINE

MIX LIKE PIE CRUST. PAT INTO THE BOTTOM OF A 9X9 PAN AND BAKE FOR 10 MINUTES @ 350 DEGREES.

PART II:

1/4 TEASPOON BAKING POWDER
2 TABLESPOONS FLOUR
1 TEASPOON VANILLA
2 EGGS
1/2 TEASPOON SALT
1 CUP FINELY CHOPPED WALNUTS

POUR THIS OVER THE FIRST MIXTURE AND BAKE AN ADDITIONAL 25 MINUTES. COOL. FROST WITH BUTTER ICING.

BUTTER ICING

1 1/2 CUPS CONFECTIONER'S SUGAR
1/4 CUP FLOUR
1/2 CUP BUTTER, SOFTENED
1 TEASPOON VANILLA
2 TABLESPOONS COLD WATER

COMBINE ALL INGREDIENTS IN A SMALL BOWL. STIR TOGETHER TO SETTLE INGREDIENTS, THEN BEAT WITH A MIXER ON MEDIUM SPEED FOR A MINIMUM OF 10 MINUTES. THIS WILL BECOME THIN AND CREAMY AFTER ABOUT 5 MINUTES AND FLUFFY IN 10 MINUTES.
