In saucepan, melt 1/4 cup margarine. Stir in 2 Tbsp. flour and mix until smooth. Add 2 eggs and 3/4 cup brown sugar, firmly packed. Stir over medium heat for 4-5 minutes. Add 1 teaspoon vanilla and 2 cups chopped pecans. Mix well and set aside.
In large bowl, combine 1 box fudge brownie mix (21 oz.), 1/2 cup very hot water, 1/4 cup salad oil, 1 egg and beat 50 strokes by hand.
Grease bottom only of 9x13 inch pan. Spread brownie mixture in pan and spoon pecan mixture over top. Bake 30-35 minutes at 350 degrees F until set. Do not overbake. Cool, cut in squares. (Also good with vanilla ice cream and hot fudge sauce as desserts).
Note: I'm told that this was a Martha Stewart recipe.
