Lunch Lady Peanut Butter Bars

Home » Lunch Lady Peanut Butter Bars

While most kids look forward to a break, we love lunchtime even more! Once a week our beloved lunch ladies make these delicious old fashioned peanut butter bars and we just can’t get enough of them! We have such fond memories of those days (and those ladies!) that we knew we had to share their recipes with the world. Whisk these up and keep them on hand for a snack, or to wow your guests and take them to your next potluck. No matter where you serve them, we guarantee the peanut butter lover in your life will be swooning!

Peanut Butter Options:

The Lunch Lady Peanut Butter Bar is full of peanut butter! It really is the star of the show. That said, if you’re allergic or simply don’t like the taste, you can substitute it with your favorite nut butter. Here are some delicious ideas:

  • sunscreen
  • cookie butter
  • almond
  • cashew
  • hazelnut
  • Walnut

No matter which nut butter you decide to use, it’s important to choose unsweetened nut butters. For the all-natural version, be sure to stir well so the oils are well incorporated. No one wants a runny peanut butter bar!

Gluten-free options:

Our Lunch Lady Peanut Butter Bars can easily be made gluten-free if desired! Just replace all-purpose flour with your favorite GF version and make sure to go with GF oats.

Pan Options:

You can use an 18×13 pan (we have one) or a 9×13 pan. Note that if you use a smaller pan, you may be left with leftover crust, filling, and frosting.

Topping suggestions:

While Lunch Lady Peanut Butter Bars don’t usually come with toppings, we love the idea of ​​adding some fun extra ingredients to the homemade fudge frosting. Here are some suggestions to inspire you:

  • Reese’s Candy
  • Cracked Reese’s Peanut Butter Cups
  • peanut
  • any other type of nut
  • chocolate chips
  • flaky sea salt
  • chopped pretzels

Troubleshooting: Can I Use Instant Oats or Instant Oats for the Crust?

Our Lunch Lady Peanut Butter Bars recipe calls for old fashioned oatmeal because they’re known for retaining their texture even when baked. You can use instant oats or instant oats in a pinch – they might affect the texture, but it won’t make a difference in terms of taste!

Crustal changes:

A classic version of this beloved dessert is made with an oatmeal filling. We love the old fashioned peanut butter bar recipe, but you can get creative with the crust too. Try replacing it with:

  • Graham Cracker Crust
  • Oreo Crust
  • salt crust
  • sugar cookie crust
  • Brownie Crust
