Chocolate Peanut Butter Oatmeal BarsChocolate and peanut butter has to be one of my very favorite flavor combinations. SOOooo good! So, when we were in Nebraska visiting family this past fall and there was a pan of these tasty chocolate peanut butter oatmeal bars made for our arrival (thanks to my mother-in-law), we couldn’t resist diving into the pan! She has so many old, small-town cookbooks and recipe cards. You know, the really good, frequently used ones that have hand-written notes, have yellowed over time, etc. And this one was a winner! I mean, don’t they just look divine?!Chocolate Oatmeal Peanut Butter Bars

Super yum! And, they are really easy to make!!! Here’s the easy recipe!

    1. I think you can use either. My mother-in-law usually only has quick oats in the house and makes these all the time. But I only buy old fashion and think they are fine that way too.
