Peanut Butter Bars are one of the best treats! You get a chewy oat cookie base that’s loaded with peanut buttery flavor, then it’s topped with a layer of peanut butter after baking and finished with a decadent chocolate frosting. Trust me this is a staple recipe!
The Best Peanut Butter Bars!
These are one of my favorite all time favorite childhood treats. My mom and everyone else I know always made them. They’re just one of those old fashioned classics!
They are perfect for parties because they make a full cookie sheet, and adults and children alike absolutely love them.
I mean, who doesn’t love the chocolate and peanut butter combo, and who doesn’t love cookie bars and frosting?
I made them yesterday and it’s one of those things where I kept going back and cutting off a thin slice, then another, then another and then I woke up for breakfast at it was the first thing I just had to have a taste of.
They really are one of the most tempting desserts you’ll ever make! Try them and you’ll see what I mean.

How to Make Peanut Butter Bars:

Tips for this Recipe
- Don’t use crunchy peanut butter or it will throw the recipe off.
- Add peanut butter while cookies are still warm so it melts nicely and sort of absorbs into the cookies a little.
- Be careful not to over-bake these or the edges will be dry. Plus they’ll continue to cook just a little once removed from the oven from the heat of the baking sheet.
