Chocolate Peanut Butter Squares

To be clear, I gave up Facebook, NOT chocolate, as my New Year’s Resolution. Good.

Now, I don’t like to think of myself as fussy, but sometimes one detail being out of place will cause me to not do a recipe for you. Case in point, several years ago, my friend Kim sent me a ridiculously easy and delicious recipe for peanut butter and chocolate candy. I believe she, in turn, got it from a neighbor.  I have made it 5 times and devoured it each time. It TASTES like a dream. Here’s the problem.

Each time I make it I run into this issue: “Well what if I…1) made the peanut butter from scratch; 2) bought fancy chocolate and tempered it for a perfect top; 3) rolled little balls of peanut butter and made pop-able bites…etc. etc. Every time, I basically ruin its absolute simple perfection. So, instead of kicking this can down the street any more, as I am wont to do with certain recipe with which I like to tinker, I’m just going to give it to you the way Kim gave it to me, albeit with one or two tiny tweaks. This is a perfect little treat and a wonderful cure for a sweet tooth.. It is an easy treat to make for a gathering It is practically a “throw-down” and it is good. You can experiment with milk chocolate or with nice chocolate bars. But whatever you do, enjoy!

Just make sure you have a lot of people coming around. Do not make it when you are alone and planning, for instance, to sit on the couch watching Terms of Endearment by yourself one evening…not that I would ever do such a thing. You could, hypothetically, eat the whole tray by yourself. This is not a capital idea, in theory. Not that I would know.

Chocolate Peanut Butter Squares
Recipe type: Dessert
Prep time:
Total time:
Serves: 48
This candy is easy and utterly addictive.
  • 1 cup creamy peanut butter
  • ¼ cup butter, softened
  • ¾ teaspoon vanilla
  • ¼ cup brown sugar
  • 1¾ cup confectioners’ sugar, sifted
  • 1 teaspoon unsalted butter (for pan)
  • 1 (12 ounce) bag of semi-sweet chocolate morsels
  1. In the bowl of an electric mixer, combine the peanut butter, butter, brown sugar and vanilla until smooth. Finally mix in the confectioners’ sugar. Beat until smooth. You can do all of this by hand in a pinch but it takes a lot of mashing and mixing.
  2. Prepare a 9 inch spring-form pan by lining the bottom with parchment paper and buttering the edges. You may also make this in any roundish dish that is approximately 8 to 9 inches across. This will change the thickness of the candy, but it is not a deal-killer. Press the peanut butter mixture into the bottom of the pan. If it is too sticky to handle, use a spatula to press it down. You can cover this with plastic and place it in the refrigerator while you prepare the chocolate.
  3. Melt the chocolate chips, either by microwaving them for 30 second bursts at 50% power, and stirring between bursts. Or, you can melt them in a double boiler, stirring continuously. When the chocolate is melted, pour it out on top of the peanut butter and smooth it with a clean, dry spatula. Set the pan aside for 15 minutes.
  4. When the chocolate is beginning to set, you can take a toothpick and “score” the top into squares, which will make it easier to cut when it is completely hardened. Also, run the toothpick or stick around the edge of the pan. If you do this too early, the chocolate folds back in on itself, which is pretty but will not help as much when you cut it later. Let it set for about 15 minutes and check it with the toothpick to make sure that the lines will hold. If it is still too "wet" allow it to harden a bit more before scoring. Place the pan in the refrigerator for an hour to allow the peanut butter and chocolate to harden completely. Or simply leave it on the counter to harden.
  5. When the chocolate has hardened, gently unlock the pan and remove the sides. You can now slide the chocolate treat onto a serving platter, trimming the parchment close to the edge. You can serve it whole and allow folks to cut off bits with a knife, or you can carefully cut off squares to serve.
This comes together quickly but will need some time to harden before serving.

[Bottom Right: To easily score the chocolate, place a long ruler over the pan, and run a knife, toothpick, or a skewer across the chocolate to draw straight lines. Turn the ruler 90 degrees and score in the other direction to create squares.]

Dish Choices: The spring-form pan makes it easier to cut the bites. If you make it in a dish or some sort, you will have to carefully scoop out the first couple of bites to get it started. A fork works great if you are not a stickler for appearances. This is why I score the top before it sets completely, too. It leaves easy cutting lines for cutting. If you don’t score the top, the hardened chocolate can squash the peanut butter layer a bit.

[I like the way that the chocolate bends on the lines when you score the chocolate when it has yet to become too stiff. However, for easiest serving, it is best for the chocolate to be slightly more hardened than in the left hand photo. You have to guess a bit. The outside edges will become hardened sooner than the middle. Either way, the scoring…when gloopy or hardened, helps a great deal with cutting the pieces.]

A word on chocolate: Chocolate can be a pain. God knows I adore it, but if you don’t know what you are doing it will turn on you. Have you ever had perfectly melted chocolate seize on you when you were trying to stir something into it? It is awful. It turns gloopy, or hard, and generally unusable for the purpose at hand. A mere drop of water can cause the whole batch of chocolate to seize. That is why I don’t add anything to the chocolate here. Many people use corn syrup or butter to make the chocolate a bit shinier. But, I don’t. Someday, I will actually take the time to temper chocolate and make very professional looking little chocolates, but today is not that day, and this is not that candy.  If you use a double boiler, make sure you don’t get it to a frothy boil or even the steam can make your chocolate seize. I boil the water and then turn off the stove, and then add the top full of chocolate. It is slower, but it is safer. The very easiest method is to microwave it in 30 second bursts at 50% power. Stir each time and then repeat until the chocolate is almost fully melted. The residual heat in the chocolate will cause the chocolate to melt completely within moments. This, and softening butter, are the only reasons I miss having a microwave.

Many thanks to my friend, and fellow Old High alumnus, Kim Johnson Puricelli for this wonderful treat.

    do you store these in the refrigerator? which brand of peanut butter have you found works best in your recipes? i’m partial to skippy for baking, and wasn’t sure if it played nicely with others when making candy.

    curious also, would a foil or parchment paper sling work in an 8×8 sized pan? then you could lift it out and slice. what about cutting using a rolling pizza slicer-gadget-thingamabob?

    i think these are perfect as they are but if you did roll and dip them then they would be similar to buckeye candy in which you almost dip fully but leave a center peanut butter spot on top. you know what though, if you put a layer of chocolate on the bottom, these would mimic a peanut butter cup and that would be truly fantastic :)

    Leanna, I use JIF. I think every PB will give a slightly different consistency to that layer and you can add a little more confectioners sugar, if necessary. It needs to be fairly stiff. I store them on the counter top. I think covering them with saran wrap too early can cause the surface of the chocolate to get pocked, though I don’t know why. It probably has to do with cooling and trapping moisture. Anyway, yes I think the sling idea would work. The chocolate is probably thick and hard enough to withstand the removal, as long as you score it well along the outer edge to loosen things up. It would be sad if it broke down the middle. This is a dead ringer for the buckeyes and I have seen many recipes that use muffin papers to make actual PB cups. They put a little of the chocolate in the bottom, form the PB into patties and place one in each of the cups, and then fill them over with the chocolate. It would be a great plan. But the reason I like this way is it takes out 100% of the fuss. You are just like me Leanna, and your wheels are turning on how to make it in a 100 different ways! Let me know if you play around and make changes. (Leanna is actually a candy maker and baker…she is a pro). I love the pizza wheel idea. I think it would work if you had done very precise scoring, otherwise it might cause cracking, But I’ll definitely play with that idea next time I need to gain 5 pounds.

    Kelly – As a chocolate lover you can be sure that I try this soon. I picked up on your problem with chocolate chip “siezing” because I had the same problem just a couple weeks ago. I didn’t want to throw the whole thing out so I called Nestle’s. The lady there said when that happens to add 1 Tab. of salad oil for each cup of chocolate chips I used. It worked beautifully!
