4 tablespoons butter or margarine
2 cups firmly packed brown sugar
¾ cup flour
2 cups chopped nuts (I use pecans)
¼ teaspoons baking soda
2 teaspoons vanilla extract
Preheat oven to 350°F. Melt butter in two 9″ square pans, or one large cake pan (I pop mine in the oven while it’s preheating, but watch it carefully so it doesn’t burn). Beat eggs slightly. Combine sugar, flour, soda and nuts, and stir into the beaten eggs. Then stir in the vanilla extract and mix well. Pour this mixture over the melted butter in pan(s). DO NOT STIR! Slide pan(s) into the oven and bake 30 minutes.
Turn out of pan(s) onto cooling racks. Cut into diagonals or squares, and dust with confectioner’s sugar.
(The argument for using 2 smaller pans is that it makes them easier to turn out onto the cooling rack after baking; however, you may need to decrease baking time if you use the smaller pans.)
