Congo Bars

Congo Bars have been a family favorite for a long time. I had a sudden craving for chocolate today so I decided to make these. They are delicious!
Melt 3/4 cups of butter
Add one lb. of brown sugar (2 1/3 cups)
Add 3 eggs
Add 2 3/4 cups of sifted flour
2 t. Baking powder
1/2 t. Salt
1 t. Vanilla

If you want you can add 1/2 cup of walnuts or a 1/2 cup of chocolate chips or both. I usually just add chocolate chips, but you can do whatever you want.

Put in a 9x12 inch greased cake pan Bake at 350 degrees for 30-35 minutes.
Enjoy!
