Peanut Butter Heath Bar Blondies

I needed something for a crowd.  As I searched my vast library of cookbooks for Pecan Bars, I came up short.  I have made lots of pecan bars in my day and for the life of me, I cannot remember which are my favorite.

During my search I came across these Peanut Butter Heath Bar Blondies in The Magnolia Bakery Cookbook.  I don’t really use this book often, yet with that said, these were very well received.  I had to bring dessert for 110 6th graders and these did the trick.

The recipe called for peanut butter chips, but they are no where to be found.  I altered it a little and used really good bittersweet chocolate chips instead.  I think they were almost better with the chocolate.

These are great when you need to feed a ton of people.  Light, good, crunchy, moist and delicious.

    When do you add the eggs/vanilla? Does it effect the turnout?

      Thanks for pointing that out to me! I added the correct instructions and updated the post. The eggs and vanilla are added after the sugar and butter are creamed together. Have a great day and please let me know how they turn out!
