my mother years ago bought a recipe on a piece of cardboard that had a recipe for chocolate brownies on it for $1.50 but cant find it anymore..

the problem is that the recipe contained chocolate topping (the kind you put on icecream) in the ingredients for the batter and she is wanting to try to make them again...mum had this recipe about 30 years ago and now cant find. I would be greatfull if someone can help me with this matter...
