Peanut Butter Cup Bars

Exactly 9 days post-New Year’s my aforementioned aversion to sweets disappeared like a puff of smoke. The holiday sugar cloud has lifted and I am ready to dive into butter, chocolate, sugar and, of course… peanut butter! These peanut butter cup bars are nothing new to the blogosphere, but I am thrilled to finally have them back in my kitchen. I had my first encounter with these bars waaaaaay back in college. I was at a cookout/bonfire and a girl brought a pan of these. I’ve been a peanut butter fanatic pretty much since I uttered my first words, so needless to say I fell in love with these immediately. As soon as I wiped the peanut butter and chocolate crumbs off my mouth, I asked for the recipe. I got it, and then promptly lost it before I ever got a chance to make them. I have lived without these for way too many years, so I must make amends. And share with you of course.

I was the kid on Halloween that dug through the candy to get to the Reese’s peanut butter cups. They were gold. On Easter, I was always thrilled when the bunny left a Reese’s peanut butter egg or, as I got older and more appreciative of good sweets, a Sarris peanut butter meltaway egg. So imagine how insanely excited I am that these taste just like a giant peanut butter cup. I could get even more authentic with a thicker layer of chocolate, or actually encasing a cup-shaped version in chocolate, but this recipe is super easy and darn-near perfect. If it ain’t broke…

Peanut Butter Cup Bars
Ingredients
- ½ cup (113.5 g) unsalted butter
- 1¾ cups (210 g) powdered sugar
- 1 cup (258 g) smooth peanut butter
- ¾ cup (63 g) graham cracker crumbs
- ¼ cup (56.75 g) unsalted butter
- ½ cup (90 g) milk chocolate chips, or chopped chocolate
Instructions
- 1. Line an 8x8-inch square pan with foil, leaving enough to hang over the sides, then butter the foil. Set aside.
- 2. In a medium saucepan, melt the ½ cup of butter over low heat. Once melted, remove from heat and stir in the powdered sugar until smooth. Stir in the peanut butter and graham cracker crumbs until completely combined and smooth. Spread the peanut butter mixture into the prepared pan and smooth the top.
- 3. In the now-empty saucepan, melt the ¼ cup unsalted butter. Add the chocolate and stir until almost completely melted. Remove from heat and continue stirring until completely melted. Pour the melted chocolate over the peanut butter layer and smooth into an even layer.
- 4. Refrigerate for at least 30 minutes to set. Remove from the pan using the foil overhangs and place on a cutting board. Use a pizza cutter to slice into 16 bars. Store in an airtight container in the refrigerator.

I love your site and I love peanut butter cups! I was the same as you as a kid…all I wanted in my easter basket was peanut butter cups (and M&Ms). Can’t wait to try this recipe with my favorite dark chocolate.
Wow – these look perfect! So elegant and rich – I must try them, and I’m not even a huge fan of peanut butter anymore!
These bars look heavenly! I am a sucker for PB treats!
Reese’s are my favorite too! This is definitely going in my recipe file. Delish!
Wow, these look so amazing! We are huge peanut butter cup lovers in this house, too, and for some reason I have yet to try making me I own… I think I’ll have to now!
My mom made these for us when I was growing up. We called them Homemade Tasty Cakes {holla, PA!}. There is something so wonderful about chocolate and peanut butter together that I just cannot resist it.
Oh, and I swore off sweets too. I’ve baked three times since January 1. Good work on my part.
LOL! Love to see Pennsylvania represented :)
Yummy. I love these bars.
Umm, these look AMAZING.
I agree with Caroline! These are dangerous becuase not only will they taste fantastic but they are way too easy to make! That means they will be waay too tempting to make all the time!
All the taste of a peanut butter cup with the simplicity of a bar cookie?! Don’t mess with success! That’s called efficiency!
I agree, these are great! Been making them for years, they are in my recipe binder but somehow they don’t get made very often… wonder if I have the ingredients on hand….
Are you supposed to break up the graham crackers really well?
Hi Angi, Yes, the graham crumbs should be crushed very, very fine.
Thanks the info, can’t wait to try these!
Oh my wow! These look incredible! Peanut butter anything is my favorite too. I just had Reece’s ice cream last night and it was heaven. Aaaah! I want to make these!!
Ok, either I am going to have to quit looking here or just quit making!!! Because I am going to be huge, especially with all this snow, and seeing how I don’t like it so I stay inside like a hermit!!! Thanks for another great recipe!!! Dang it! (In a good way!)
bookmarked this one; I’m drooling right now
These look delicious! Would they work with organic peanut butter too?
I agree- what aversion to sweets? What resolution?! I have all the ingredients on hand… stuck inside on a snow day… bad things could happen!
I love bars like these! They look incredible!!
Wow. I should absolutely not make these. I would eat the whole pan.
I don’t like peanut butter myself, but I’ve been debating on trying a similiar recipe for my husband who LOVES peanut butter cups. Yours look so creamy and easy to make too! I may have to make them for him for when my beloved Steelers beat his sorry Ravens this weekend!
GO STEELERS!!!
I made this recipe too, and I was amazed! It tastes exactly like a peanut butter cup! I tried to experiment by using a white chocolate topping, don’t do it. Delicious, but so much harder to work with. If I try this again, I’ll definitely just stick to the chocolate like the recipe says.
I have been wanting to make these! Last night I started REALLY missing sweets. 10 days is a long time of being “healthy”!
These look amazing and wonderful and like I NEED to make them :)
Wow so so delicious lookingm i love the way you have stacked them up.
Thank you so much for this recipe! I’m always looking for no-bake recipes at the moment since my oven access is a bit iffy. These bars look absolutely scrumptious :)
Yum! These look fantastic. I adore peanut butter, can’t wait to try these
These look WAY too good. Like “get out of my kitchen and stop taunting me” good. Seriously, these wouldn’t last 5 minutes in my house. Amazing!
These sound so easy and look scrum-diddly-uptious! ;) My daughters thank you in advance for sharing this recipe, as we will be giving these a go this coming weekend. :)
These are so sinfully delicious looking, Michelle! I could for one right now, matter of fact. Thanks for sharing!
Was my other comment sent to spam?
Hi Sean, I just checked and it was, but I approved it so you should see it above now. Thanks!
Wow, those look delicious, though if I were to eat them I’d probably dip them in chocolate and possibly have whipped cream on them lol.
