Yummy Cookie Bars

I received this recipe from a special co-worker at school, and it is always a huge success when I make them. It works great to make them a day in advance. It will allow the bars to set and be cut easier.

    Perfect! Forgiving recipe and allows you to customize taste. Change cake mix flavor or type of chocolate. Universally loved. As volunteer field editor with Taste of Home magazine I love recipes that I can easily customize and know it be a hit!

    I meant to say that I'd used an 11-oz. package of Nestle's combination of Peanut Butter AND Chocolate Chips. Everything else was kept as recipe stated! 5* recipe for sure!

    Amazing. Made this with my 4 year old for a potluck because it was easy and I had all the ingredients on hand. This exceeded my expectations and may be my new go to dessert bar.

    A hit with my kids and their friends! Very easy to make however I did not have a white cake mix so I used yellow and it was perfectly fine. I used all milk chips too because its what we prefer. I definitely recommend this recipe!

    Very good and easy to make. I used all semisweet chocolate chips (my family isn't big on peanut butter), and the topping was chocolatey, rich and creamy - delicious! I also flattened small balls of the remaining dough for the top to give it a neat polka dotted look. I will be making this for an upcoming church social this weekend :)

    I have made these Yummy Cookie Bars several times and everybody who has sampled them has simply raved over them. One of the best new recipes that I have tried and so very simple to make with ingredients that are always on hand. Five Star Recipe.
