This is the simplest brownie recipe I've ever come across and they are really good!

1 Cup Sugar
1/2 teaspoon Vanilla
1/2 Cup Flour
2 Eggs
1/2 Cup Melted Margarine
1/2 Cup Cocoa

Preheat oven to 350 degrees. Beat sugar, eggs, vanilla together. Add margarine and mix well. Sift dry ingredients together and add to wet miture, mix till well blended. Pour into greased 8x8 inch pan and bake for 25-30 minutes. Ice if desired.

For variety I like to cut up Milky Way or Reese's Peanut Butter Cup and add to mix, I usually pour in pan and then sink the pieces into batter so i can assure even distibution. 1/2 Cup of any kind of nuts works well too. Give 'em a try!
