Best Peanut Butter Bars on the Planet!

When my girls first started school,  I can remember taking them to 1st grade orientation to meet their teachers and see their new classrooms for the first time. The Lunch Ladies had prepared Peanut Butter Bars for the refreshments. Up until that time, we had never tasted such goodness! We knew it was going to be a good day when they were serving these as the dessert with school lunch!  Later, when one of my daughters went away to college, she got this recipe from a roommate. Life has never been the same! These are a great to take to a potluck because it makes a bunch! I have played around with the recipe a little bit and…here’s what I came up with:

  1. I guess Jelly Roll Pans come in 2 sizes. 10 1/2″ x 15 1/2″ x 1″ (10 cup volume). & 12 1/2″ x 17 1/2″ x 1″ (12 cup volume). What size Jelly Roll Pan do you use to make yourBest Peanut Butter Bars on the Planet? I would like to make this recipe for my grandkids. I think they will love them!

      1. Thank you so much for your prompt reply. I thought these would be a great idea for their visits to our house & for camping too. I don’t like the flavor/sweetness of store bought canned frosting. Do you think I could use a milk chocolate ganache instead?

  2. How do you get the jellyroll pan into your fridge to cool. I dont think mine will fit,,,, will the peanut butter ever set up enough outside of the fridge to frost??

    1. It will set up slightly when it cools. Just make sure your frosting is room temperature so that it’s spreadable. Enjoy!
