Prepare and bake brownie mix in a greased 13"x9" baking pan according to package directions. Let cool. Mix powdered sugar, 1/2 cup butter and peanut butter. Mix well and spread over cooled brownies. Chill for one hour. Melt together chocolate chips and remaining butter in a saucepan over low heat, stirring occasionally. Spread over brownies. Let cool; cut into squares.
Tip: Make frosted bar cookies look extra-special! Lightly press a cookie cutter into the frosting, then use a tube of contrast-color frosting to trace the outline.
"I must say this is the best recipe software I have ever owned."
"Your DVO cookbook software saves me time and money!"
"I saw lots of recipe software for PC computers but I was having a hard time finding really good mac recipe software. I'm so glad I discovered Cook'n! It's so nice to have all my recipes in a computer recipe organizer. Cook'n has saved me so much time with meal planning and the recipe nutrition calculator is amazing!!!
My favorite is the Cook'n Recipe App.
