Reeses Peanut Butter Cup Magic Crust Cookie Bars
It’s still National Peanut Month so let the peanut butter love continue, right? I made these bars a couple of weeks ago to bring to a friend’s house. Yesterday I started making another peanut butter dessert because my two sisters who live out of state are coming home for a visit! Woohoo! It isn’t quite done so I am sharing the bars first and will share the other dessert next week. I know I said I am watching what I eat and eating healthier! That is still true and that is also why I make delicious treats like this to share with others!

Crunchy Peanut Butter My husband is the biggest peanut butter fan I know. He’s loved it since he was a kid and it is one of those things that everyone knows about him. His friend’s parents and even some of their grandparents would keep crunchy peanut butter in their cupboards for when he came to visit. Once when we were dating my friends gathered up a bunch of the individual sized peanut butter packets from eating out at restaurants and presented them to him as a joke. His favorite is is crunchy peanut butter but I like both the creamy and the crunchy. A friend of mine has a slight addiction to dipping carrots and celery in creamy peanut butter. She is doing her best to spread her fondness for the combination far and wide. So, what does that have to do with these bars? Nothing really, but that is what this spoonful of peanut butter made me think of.

    Because of the sweetened condensed milk, do these need to be kept in the fridge or just left on the counter? I’m making them as we speak and wasn’t sure. They look delicious!!

  2. Joyce says

    If you grease the pan why do you need to line with foil? It would seem to me that it would be difficult to cut into bars if you line the pan with foil. Are you lining with foil just to make cleanup easier?

    • Tonia says

      Hi Rina,
      The only place it stuck for me was a little along the edges and I just carefully peeled it off. Be sure to grease the foil and I would suggest not pouring the sweetened condensed milk all the way to edges. Worst case scenerio, cut a half inch off each edge (where the caramelized sweetened condensed milk is) after baking. Best of luck and thanks for stopping by!

    Tried this recipe last night and I couldn’t wait to dig in to it. It was good warm but this morning after it had time to cool the entire night, it was delicious!! I made a mistake by buying dark chocolate mini reeses and mini chocolate chips but I used them anyways…guess I need to pay more attention at the grocery store!

    I had these bars at a reunion and they were wonderful. Made with crunchy pb and they left off the reseese minis on top. Have looked for this recipie for 3 weeks and finally got it. Yum Yum

  5. Christa says

    Any suggestions on using something other than condensed milk on top? That’s the only part that’s turning me off. Also, I plan to chop up the regular sized Reese’s cups as I like the peanut butter part better than chocolate and I’m going to omit the pb chips 🙂

    • Tonia says

      Hi Chista,
      The condensed milk turns to caramel so I would suggest using caramel if you don’t want to use sweetened condensed milk. I am not sure about the amounts because I have never tried it but I would love to hear how it turns out!

    Just dropping in with some nutrition info input! I calculated all of it because I wanted to know exactly how bad these were for him before I sent them off to my boyfriend xD.

    I used Duncan Hines white cake mix; Great Value brands of smooth peanut butter, sweetened condensed milk, and 100% canola oil; Reese’s Peanut Butter Chips and Mini Cups; Hershey’s semi-sweet chocolate chips; and a regular egg. This is assuming they’re cut into 16ths.

    hi,do you make the cake mix accordingly to directions with the water and all?..or do you just put the peanut butter and oil and egg in the dry cake mix?thanks

  8. Gayle says

    It sounds awesome, everything we live. But to be honest…it kinda looks disgusting. Because of the condensed milk. 🙂

    Hello Tonia
    I was wondering if you know, roughly, how many calories are in the Reese’s Peanut Butter Cup Bars? I want to make them, but I’m watching how many calories I eat in a day, due to my doctor telling me I need to cut my calorie intake. Apparently I was eating too many calories in a day and didn’t realize it. Anyway, if you could let me know what you think, that would be great. Thanks! (The calories for the whole dish or just one slice would be enough, thanks :3)

    • Tonia says

      Sorry Macie! I really don’t know. Unfortunately, I am sure there are way more calories than are good for anyone to consume!

    • TK says

      There are 310 calories in one bar using her recipe and cutting into 20 bars, I have an App that calculates it for me. I used chunky pesnut butter, Reese PB chips, pllsburry cake mix and nestle condensed milk but generally speaking brands are pretty universal nutrition wise so even using different kinds it would probably be around the same calorie countent,

      These were a huge hit, gone in minutes and people thought I’d spent hours making something that took 15 minutes, seriously fool proof! I did ass a little water to make it easier to mix by hand especially bc I was using extra crunchy peanut butter

  10. Damien says

    My good friend Donna just shared this recipe on Facebook. By tomorrow evening, her and I (and some other friends it seems) will be sharing these!!! Thanks for the post!

    • Tonia says

      Hi Katie! There are 16 tablespoons in 1 cup so you would need 8 tablespoons of peanut butter and 4 tablespoons canola oil.

  11. says

    Are you kidding me?? When I die and go to heaven these will be served to me on a silver platter with zero calories!!! These look AWESOME! You just made the world a better place by creating these! Hehe Pinned!
