Peanut Butter Squares

Peanut butter squares

Peanut Butter Squares just like the lunch ladies used to make at school! No-bake, easy to make with a chocolate frosting that’s hard to resist!

Peanut Butter Squares and Peanut Butter Bars are one of those treats that everybody loves! I’ve seen recipes that are baked, others that are no bake. Some are made with oatmeal or corn flakes, others are made with graham crackers. Some are made with peanut butter frosting while others are made with chocolate frosting. My version is just like the ones I used to get when I was in school, the ones that the lunch ladies would pass out and everybody would devour! My version is no-bake, made with a few simple ingredients and topped with chocolate frosting!

Did I mention that this recipe for Peanut Butter Squares comes directly from the lunch ladies? 

When my hubby was in high school, he was extra nice to the lunch ladies in hopes that they’d throw extra food on his tray every now and then. And they did. I’m pretty sure he even brought them a little gift for Christmas to ensure the extra food continued. When his favorite peanut butter squares were on the menu, they’d usually give him two, and often times if there were extras, they’d save them for him and he’d get them the next day at lunch. How lucky was he?

When he was a senior and it was time to graduate, the thought of leaving behind these peanut butter squares was just too much, so he actually asked the lunch ladies for the recipe, and they were happy to give it to him. The recipe they jotted down was lacking in details, and it was enough to fill one of those mega trays that make enough to feed a small army! I’m sure he wouldn’t have minded if I made the whole mega tray so he could munch on them for days upon days, but I reduced it down to a more suitable 9×13 inch version.

One thing I love about these little babies is that they are no-bake! The first time I made them, I was convinced that the lunch ladies had forgotten to jot down the baking instructions, so I came up with my own. BIG, big mistake. Would you like to know what happens when you bake what is meant to be a no-bake treat? In this case, the peanut butter melted and began overflowing and oozing over the edges of the pan and settled on the bottom of my oven. Can you imagine the mess I had to clean-up? It was NOT pretty! Lesson learned.

If you love peanut butter as much as we do, this recipe for no-bake, no-muss, no-fuss peanut butter squares straight from the lunch lady at school promises to send you into peanut butter oblivion! Enjoy!

    Me, I just love peanut butter – add dark chocolate and I’m in heaven !!! Thank you !

  3. I believe those who loves peanut butter, loves it deep! This is just Peanut Butter overload. YUm yum yum!

  4. The funny part for me: at the end of my last year in grade school, my mother asked the lunch ladies for this recipe, too! They scaled it down for her and it was a little different (no graham cracker). I’ve always had to refrigerate it to get it to firm up enough to spread the chocolate on the top, and then have to refrigerate again which makes it a major pain to cut! I look forward to trying yours and seeing if it solves all my problems. This is my husband’s favorite treat, so if it does…thank you!!!

    • Hi Allison, you definitely don’t have to refrigerate this recipe to spread the chocolate. Your’e actually supposed to spread the chocolate before allowing it to set, so hopefully it solves your problems! :)

      I guess the good news about this is that at least there’s a school lunch item that’s good enough to ask for a recipe?

    Cant wait to try this one quick and easy and nothing better than chocolate and peanut butter

    • I agree Kim! These are a favorite, especially since they’re no-bake!

    My mom was a lunch lady. She made these for us and the neighbors. You can also change it up a little. Use Rice Crispies instead of graham crackers and she would use different chocolates for the top. Now that I make them, I use different nuts like almond butter and hazelnut. Makes a decadent treat.

    • That’s awesome, Melissa! Thanks for the suggestions to change it up!
