Did your high school cafeteria have any good treats that you still think about to this day?  My high school had these incredibly soft M&M cookies that I still miss.  When I came across a recipe for Lunch Lady Peanut Butter Bars, it immediately peaked my interest because of my fond memories of the beloved lunch lady cookies that I remember.

Lunch Lady Peanut Butter Bars {Satisfy My Sweet Tooth}

Chocolate and peanut butter in any recipe gives me high hopes that I will fall in love with the treat.  These cookies begin with a soft and chewy peanut butter oatmeal cookie base.  As soon as you take the cookies out of the oven you smear them with more peanut butter so that it melts with the warmth of the cookie crust.  Finally, top all of that goodness off with a classic chocolate frosting and you’ll have visions of adorable lunch ladies dancing in your head when you eat one of these Lunch Lady Peanut Butter Bars.

Lunch Lady Peanut Butter Bars

Prep Time: 10 minutes

Cook Time: 15 minutes

Total Time: 25 minutes

Yield: 16 bars

Lunch Lady Peanut Butter Bars are based on a peanut butter oatmeal cookie crust and smeared with more melty peanut butter and perfect chocolate frosting


  • 1/2 cup (8 Tbsp) unsalted butter, softened
  • 1/2 cup sugar
  • 1/2 cup brown sugar
  • 1 tsp vanilla
  • 1 egg
  • 1 1/4 cup cream peanut butter, divided
  • 1 cup rolled oats
  • 1 cup flour
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • For the frosting:!
  • 1/4 cup (4 Tbsp) unsalted butter, softened
  • 2 Tbsp milk
  • 1 tsp vanilla
  • 1 1/2 Tbsp cocoa powder
  • 1 1/2 cups powdered sugar


  1. Preheat oven to 350 degrees.
  2. Grease an 8X8-inch pan.
  3. In a large bowl, using an electric mixer, beat together butter, sugar and brown sugar for the bars. Add vanilla, egg and 1/2 cup peanut butter and mix well to combine.
  4. Add oats, flour, baking soda and salt and mix well.
  5. Spread batter into prepared pan.
  6. Bake 15-18 minutes or until lightly browned around the edges.
  7. After bars have been out of oven for 5 minutes, while still hot, spread remaining 3/4 cup peanut butter over bars evenly. Peanut butter will get melty so that it is easy to spread.
  8. Refrigerate until peanut butter solidifies again, about 15 minutes.
  9. Meanwhile, for the frosting, combine all ingredients and mix until smooth.
  10. Spread frosting evenly over bars. Cut and serve.

This recipe comes from the new cookbook from Six Sisters’ Stuff.  Can you imagine having a blog with your 5 sisters??? That’s exactly what this six remarkable ladies are lucky enough to do.  Their first cookbook is filled with easy any day recipes that they use to feed their busy families.  The sisters value getting their families to sit down together for a meal, which I admire.

Not only does Six Sisters’ Stuff cookbook offer over 80 recipes with nice color photos, but it also offers crafts and ideas such as a list of activities for children to do inside if they can’t go out on a rainy day.  The recipe chapters are divided into Main Dishes, Slow Cookier, Sides, Salads, Breads and Desserts and all of the recipes are based on ingredients that you will likely already have in your pantry at home.  Most of the recipes in this book are very simple and would be great for someone who is a beginner in the kitchen and is looking to learn some basics using easy-to-find ingredients.

There are certainly more dessert recipes in this book that have caught my attention such as the Sugar Cookie and S’mores Bars.  Many of the main dishes in Six Sisters’ Stuff are casseroles and good down home type cooking that may remind you of some of your family classics.

*Shadow Mountain Publishing sent me a review copy of the Six Sisters’ Stuff Cookbook but all opinions are, as always, my own.

    These definitely sound like a classic!

    I am quite convinced that the best thing on earth is the combination of peanut butter and chocolate. And what a way to enjoy it. 🙂 I want to eat that frosting with a spoon Mercedes!

    I was just on another blog and randomly had clicked to an archived post for bars that look very similar to these, then popped over her and it’s more…PB bars! My PB bars/lunchlady bars that I remember from our caf didn’t have an oatmeal crust at all. There were just sort of a solid-ish PB with the choc top. Your look great!

    I emailed my contact at the spatula place. So far..they have not written back. If I hear anything, I will LYK!
