Peanut Butter Bars Recipe

What is it about Peanut Butter Bars that make the world just feel right. Since Little Buddy was just a wee one, we’ve been making these peanut butter bars together. He’d sit on the edge of the counter, swinging his feet as we poured all of the ingredients for the peanut butter base into a large mixing bowl to mix it all together.

His favorite part of making these peanut butter bars has always been to dump the confectioner’s sugar into the bowl, the cloud of white sugar dust bringing out his contagious giggle every single time.

We celebrated his visit to the orthodontist by making these yesterday. You see, we were fully prepared for the orthodontist to reinstall the bottom device at our visit, but Little Buddy must have some major luck.

Over breakfast, he told me that he sure did hope he didn’t have to have the device reinstalled until after his birthday. To which I sympathized for a little bit, but then gave him a motherly version of a dose of reality.

“Honey, that’s over a month and a half away. I wish you didn’t have to go through all this as well, but the result will be so worth it.”

To which I received an eye roll and a sideways grin.

As we walked into the orthodontist’s office, I gave Little Buddy’s hand a tight squeeze and told him it would be over soon enough.

Less than five minutes later, we were walking back out the door to our car. Well, I was walking. Little Buddy was literally floating, skipping, and dancing in one huge combined movement. Walking on air would be a great analogy.

And Little Buddy had gotten his wish. His next appointment was scheduled for the day after his birthday for his bottom quad to be reinstalled.

Lucky duck!

These peanut butter bars really make anyone feel pretty lucky though. They are so simple and quick to make, but taste like they were super hard to make. That’s why Little Buddy and I have been making them together for so many years. Five ingredients is all it takes to make these babies.

These peanut butter bars are perfect for tailgating, game days, serving on your Halloween dessert table and for gifting and disappear quicker than you would ever imagine! We also love to make them on camping trips in the RV.

But, I remember that my Mama would sometimes make them just to tuck into my Charlie’s Angels lunch box. When I’d open the lid to discover a peanut butter bar inside, I felt like the luckiest girl alive. There’s just something about that whole peanut butter and chocolate combination that’ll do that for you.

Here’s my recipe for Peanut Butter Bars. I know you are going to love them!

    Lucky guy….for his good appointment AND to have a mom who makes these bars! These look INCREDIBLE!!! I’m tempted to stop what I’m supposed to me doing and make these right this second. They are calling me!!!

    Hi Robyn, would you be able to give me a cup measure or weight in grams for the graham cracker crumbs. We don’t have graham crackers here (South Africa) so I would have to substitute another type of biscuit crumb. I’m thinking maybe a digestive. Thanks, Susan

      Peta says

      @susan I’m also South African and hope you can tell me if you found that the digestives worked nicely ??

      Scott says

      Susan and Peta – Per the Wikipedia entry for digestives: In recipes calling for digestive biscuits, it is common to substitute graham crackers in the United States. According to Charles Panati, the original graham cracker is called a “digestive biscuit” in Britain. However, graham crackers are typically a little dryer and more brittle.

      I woul also like to know if digestive biscuits worked out. I was thinking of trying tennis biscuits.

      I’ve kept them in an airtight container on the counter for a couple of days, in the refrigerator in an airtight container for about a week, and then I’ve frozen them to serve later. So, in other words, it really depends on how quickly you plan on serving them. You could always keep a few out at room temperature and then store the others in the freezer for later. That would be a win-win!

    Not a well known snack over here in Australia, but my daughter and I are gonna give these a go tomorrow night.
    Have to figure out what graham crackers are though, as we don’t have those specific ones.
    If they turn out well I’ll let you know what I substitute in their place.

    Do you freeze just the peanut butter base before you add the chocolate to the top? I just made them and with it all being warm and melt it just blended together and looks like a marble cake lol

    I made them! Thanks for the recipe. I “have” to make them again by request, and I do plan on popping the PB mixture into the freezer for a few minutes because last time, the chocolate settled deeper in some places than others. This is really not a problem, obviously. They were fantastic anyway. But I’m going for “pretty,” too, this time!

    WOW!! I have been eyeing these for a few months (pinned it around x-mas time) and just got around to making them today!! Best thing EVER!!! I can’t wait to share these with friends and family! Thank you for sharing the recipe!!

    I’ve made these 3 times now and they are wonderful! Each time I’ve had issues with
    getting them out of the pan so next time I’ll line the pan with non-stick foil.
    Thanks for the recipe.

      That’s a great tip, Trudy! Buttered parchment may be a good option as well. So glad you love these bars. They are a favorite here, too.

    These were so good and tastes like the inside of a Reese’s Peanut Butter Cup! Only suggestion I would make is storing them in the refrigerator and then taking them out a couple minutes before serving. When left out for an hour, mine were a little too soft and harder to eat, but straight from the fridge, they were too hard.

    I’ve made these a few times and they are absolutely delicious. I definitely recommend putting the PB base in the freezer while you melt the chocolate. However, I’ve always had to store them in the fridge. Otherwise they get too gooey. Not sure what I’m doing wrong, but I haven’t been able to serve these at room temperature.

    Super tasty but when mine get to room temp they are way too soft. I live near the beach so it’s warm & humid. Any suggestions?

    Katie says

    Do you think natural peanut butter would work with this, or do you think conventional peanut butter (e.g skippy, jiff) would have to be used?

    • 42


      Hi Katie,
      I’ve not tried natural peanut butter with this recipe. If you do, let me know how it works. I’m sure others would love to know as well.

    What a great recipe. I just whipped up a batch in no time. For anyone enquiring about graham cracker substitutes, I used digestive biscuits and they worked out well. I agree that these bars taste like Reese’s Peanut Butter Cups and given that I used my favourite chocolate, Cadbury’s Dairy Milk, I fear that this recipe could now wreak havoc on my waistline!

    Deborah says

    Are these meant to be stored in the fridge/freezer? I was thinking that I would like to send them to my nephew for his birthday Can’t wait to try them, thanks!

    Robin Baez says

    I make these, but since we are Gluten free. I just skip the graham cracker. I mix the PB, vanilla and butter. Then melt the chocolate to pour on top. Think Buck Eyes, on bar form. :) My family loves these.

    Sandi Marson says

    Great recipe! Do you have any hints on how to cut them? I find the chocolate breaks up when I’m cutting the squares!

    • 49


      Hi Sandi,
      You could cut them after a few minutes in the refrigerator before they’ve completely set, return them to the refrigerator and allow them to finish setting and then you’ll have the chocolate scored to make it easier for a final cut and serve. Hope that helps!

    i would love to make these but could you translate into English measures and would any crackers do ?

    Tom Windsor says

    Hey I tried these out but I did them a little bit differently as I made the biscuit base without the peanut butter then had the peanut butter whipped with the sugar on top and then the chocolate on top.

    It was tasty. I think it would be nice with some actual nuts under the chocolate so I may try that next time. Also I may try your method of mixing the biscuits in with the peanut butter and seeing how that turns out.

    I found that I couldn’t taste the chocolate much but I was using super value chocolate so perhaps next time I will try something upmarket 😉

    Regardless, I really enjoyed the recipe!
