3/4 c Margarine, softened
3 Eggs
3/4 c Sugar
2 c Unsifted flour
3/4 c Packed dark brown sugar
2 ts Baking powder
1 ts Vanilla
1 ts Salt
1 c Chocolate chips

Preheat oven to 350 degrees F. Combine margarine, sugar, brown sugar and vanilla in a large bowl. Beat until creamy. Add eggs one at a time, beating well after each. Add the flour, baking powder and salt, and mix well. Stir in chocolate chips. Spread the batter evenly in a well-greased 9"x13" pan. Test the batter. Bake the remaining brownie (heh, heh, just kidding) for 30-35 minutes. Cool and cut into squares.
