I made these brownies up and this is what used. A lady used to sell these at work and I always wanted to try to make them.
You need a 9 x 13 pan of brownies. A box mix is fine or this is a super fast and easy recipe from Hershey's. Don't make the icing. https://www.hersheys.com/recipes/recipe-details.aspx?id=98.
To make the topping I used another Hershey recipe.
3/4 cup butter melted
1 and 1/3 cup peanut butter
3 cup confectionery sugar
Mix together until smooth consistency. Set aside.
Melt 2 cups chocolate chips and 2 tablespoons of Crisco until smooth.
Top brownies that have cooled for about 10 minutes with peanut butter mixture. Carefully spread. Then pour chocolate over top. Spread evenly and let cool. Cut and serve.
