Peanut Butter Bars

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.

Peanut Butter Bar Ingredients:

  • All-purpose flour – for structure
  • Quick oats – for texture
  • Baking soda – so the bars rise
  • Brown sugar, granulated sugar and powdered sugar – to sweeten
  • Salt – to balance the sweetness
  • Unsalted butter – to moisten and add richness
  • Eggs – to bind
  • Creamy peanut butter – to add flavor
  • Vanilla – to add another light layer of flavor
  • Cocoa powder – to add chocolate flavor to the frosting
  • Milk – to thin the frosting

 

How to Make Peanut Butter Bars:

Even though these have several layers these really are a breeze to make.

  • Preheat oven and butter a rimmed baking sheet.
  • Whisk together dry ingredients.
  • In an electric mixer cream together butter, brown sugar and granulated sugar
  • Mix in eggs one a time then blend in peanut butter and vanilla.
  • Mix in dry ingredients.
  • Spread mixture onto baking sheet.
  • Bake until nearly set.

  • Cool briefly then dollop over peanut butter, let peanut butter melt then spread.

  • Prepare chocolate frosting then pour over peanut butter layer and spread even. Let set.

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.
