1 stick (1/2 cup) margarine, melted
1 box light brown sugar
2 cups self-rising flour
3 eggs
1 cup chopped nuts

Preheat oven to 350 degrees.
Place all ingredients in a mixing bowl. Beat with electric mixer just until combined. Spread into a greased 9-inch by 13-inch baking pan. Bake for 25 minutes. Cake should be firm to the touch and golden brown. Cool and cut into squares.
