This is so easy and so good.  You'll get rave reviews from this one and I made it up. 

Ingredients:

One package of your favorite brownie mix

8 oz cream cheese

1/4 cup confectioner's suger

1 teaspoon vanilla

8 ounces cool whip

Make your brownie mix according to directions using a 13 x 9 pan.  Let cool till just warm.  Mix the cream cheese, sugar, and vanilla.  It's not easy to mix but get it somewhat blended.  Add the cool whip.  Don't try to fold it, just beat it in.  The result will be a kind of sticky frosting.  Spread on the brownies.  You can top with 2 sliced bananas and drizzle with chocolate syrup for an added treat.  Make sure to keep it in the fridge.  It's great when it's warm but it improves when it's cold.  If you're dieting use the fat free ingredients.  Great to spoil yourself or when your family to tell you how great you are.
