Rich Peanut Butter Bars


This recipe is adapted from one I found in a recipe booklet in 1985.  It’s easy to make and produces a large batch of very rich bars.  Cut into 16 bars, one bar would be fine for a serving.  These also freeze well.


1 cup all-purpose flour
1 cup rolled oats (regular)
½ cup granulated sugar
½ cup firmly packed light brown sugar
½ tsp baking soda
¼ tsp. salt
½ cup butter, softened
1/3 cup creamy peanut butter
½ tsp. vanilla
1 egg

1 cup chocolate chips

1/3 cup confectioners’ sugar
2 Tblsp. creamy peanut butter
3-5 Tblsp. milk

Heat oven to 350 degrees F.
Grease a 13×9 inch pan

In large mixer bowl, combine all bar ingredients and blend at low speed until mixture forms a soft dough.


Press dough in bottom of prepared pan.

pnbars-panBake at 350 degrees F for 15-20 minutes or until golden brown.  Sprinkle immediately with chocolate chips.


Let stand 5 minutes and then spread chips evenly to cover top.


In small bowl, combine confectioners’ sugar and peanut butter, mixing by hand.

pnbars-glazeDrizzle over chocolate frosting, and swirl with a knife.

Cool completely.  Cut into 16 bars

  1. I’m dieting!!! I can’t hear you….lalalalala…I have my fingers in my ears & my eyes closed….lalalalala. Its not working!!! LOL

    Thanks for the tempting recipe, Lillian. They look Sooooo good!!

  2. This may be the recipe I make to try out the Kitchen Aid mixer I bought from a friend who hasn’t used it in 3 years. It’s an older model, but probably better for it! I think I have everything you listed! It doesn’t have that much sugar, either, especially divided into 1/16!

  3. Wonderful recipe. Just made and am taking to work this afternoon. Every recipe is good and I appreciate that you ‘size down’ so I don’t have to do the math. BTW dezertsuz, my KitchenAid is a 1970 model, before the commercial mixers were sold for home kitchens — it’s been used “hard” and I’d not trade it for my daughter’s new one.

  4. My son-in-law is always looking for something that I can make for him to take to share with his employees – he likes this one so I will be making this over the holiday weekend for those who have to work it with him. Pinning!
