Peanut Butter Cup Bars

Peanut butter cup bars  I guess I am just in a peanut butter mood this week! First I made spicy peanut noodles and then I decided I wanted to make some kind of no-bake peanut butter bars. And I'm the boss of me, so I did.

Actually, I also hosted Friendsgiving this week at the office. If you haven't been reading since last year, Friendsgiving is an annual tradition we have here at ABM. It's a friend or office Thanksgiving. It's my favorite event every year because it's basically a cooking marathon, which is fun! If I had to do it every week it probably wouldn't be as fun, but hosting a giant dinner party is such a pleasure for me. 

Anyway, one item I had planned was a chocolate pie. I had practiced it before and it was great. Then I went to make it the day before Friendsgiving and I decided to try a slightly different cooking/baking method, and it was an EPIC FAIL. And I didn't have time to make another. I had another dessert planned, but it didn't feed everyone, so I ended up also serving these peanut butter cup bars since they were in the freezer. Life saver.

Peanut butter cup barsSo not only are these delicious (think giant peanut butter cups!), they also are awesome to have in your freezer, ready for unexpected company or when a planned dessert goes terribly wrong. 🙂

I realize this is also dangerous advice, as you could end up just systematically eating them all over the course of a week. Not that anyone would ever do something like that (wink).

Peanut butter cup bars recipePeanut Butter Cup Bars, makes nine (8" x 8" square pan).

3/4 cup peanut butter
1 1/2 cups graham crackers, crushed
1/4 cup chopped peanuts
1 1/2 cups powdered (confectioners) sugar
3/4 cup butter, melted and cooled
1 cup chocolate chips (dark or semi-sweet)
1/2 tablespoon canola or vegetable oil
1 cup chopped peanut butter cups

In a bowl stir together the first five ingredients listed. Butter a square baking dish and press the peanut butter batter into the pan. 

How to make peanut butter cup bars In a microwave safe bowl, combine the chocolate chips and oil. Melt on high for 30 seconds, stir, then melt for another 30 seconds. If needed you can melt it for an additional 15-30 seconds. Pour the melted chocolate over the top and spread to the edges of the pan. Sprinkle on the chopped peanut butter cups.

How to make peanut butter cup barsCover and freeze for 30 minutes to an hour (or overnight). Once hardened cut into squares. You can serve these right away or wrap each bar and store in the freezer.

Peanut butter cup bars I'm not positive how long these will last in the freezer if wrapped. We ate all of our ours within two days, but I bet these would store well for months if kept frozen. These are quite rich, but I still think they go well with vanilla ice cream. Just saying. Enjoy! xo. Emma

  • I made four different batches of this (two for a work Thanksgiving potluck, one for my mom’s Thanksgiving and one for my dad’s) and loved it EVERY SINGLE TIME. This dessert is awesome. I even blogged about it. It’s especially great for folks who don’t do a lot of cooking or whose ovens aren’t very good at their job anymore. It would be great with milk.

  • I am loving these bars. I think I would eat the whole pan. I cannot think of anything better than peanut butter and chocolate.

  • This just melted my heart! I love reeses and this looks like it would be my favorite dessert! Soo much for my diet but I need to try this tomorrow! Thank you soooo much for sharing!

  • Oh no! I’m so sorry about that! I bet it will still taste good 🙂 -Jacki

  • Good God, these look incredible. I want to make them right this second! I will for sure give them ago; they don’t sound too challenging so I should be fine!

  • Darn! I just finished making it…before you made the change! I was wondering what to do with the extra melted PB. I added it to the first four ingredients and it’s just yucky. Oh well. This explains why it didn’t look anything like the picture and is just a bunch of crumbs and way too peanut buttery. Fingers crossed that it will be edible after hardening up in the freezer!

  • YUMMMMMMMMMM!! Looks soo good!

  • Aww fab, thanks team ABM! I want to have a go! 🙂 Can you tell I was getting my recipe notes down, haha!

  • LOL…I quickly clicked to see what the latest, greatest topic is and misread the headline. I thought it said “Peanut Butter Cup BRAS”.
    Hey, you’re always at least on the cutting edge (and usually beyond), so, for a brief second, it didn’t surprise me! 😉

  • these look perfect! and they look so easy to make! plus, who doesn’t love chocolate and peanut butter?
    i wish i could of done friendsgiving this year, but our canadian thanksgiving has already passed.

  • Hi Elizabeth! It should say mix together the first 5 ingredients. We fixed the typo 🙂 -Jacki

  • Hi Virginia! It should say mix together the first 5 ingredients. We fixed the typo 🙂 -Jacki

  • Looks delicious & easy! Is it supposed to say mix together first five ingredients, rather than four? Otherwise the butter isn’t used.

  • Hi ABM! This looks amazing and I def want to try it out. But what am I supposed to do with the butter? Mix with the first four ingredients? Thanks!

  • As a diehard Reese’s fan, this recipe is torturously tempting. However, I would probably eat the entire pan and still want more so. It could be dangerous.

  • OH EM GEE these look amazing! Peanut butter cups are my all time fave, I’m definitely trying your recipe…like right now.

  • “And I’m the boss of me, so I did.” You and your husband have the best writing styles. All of your posts always me a little (sometimes a lot) giggle. Thank you!

  • hi these look amazing and i will make them for the rest of my life.

  • For once I’m glad the kid is allergic to peanuts so I won’t be tempted to make these, and eat them all!

  • Hi Kristen! It should be butter. We fixed the typo! Thanks for letting us know 🙂 -Jacki

  • Hi Holly! The second one should be butter. Sorry about that! We fixed the post. You might Google the best substitute for graham crackers just to be sure. 🙂 -Jacki

  • Am I being daft or is there an extra amount of peanut butter in the recipe that doesn’t get allocated in the method?! Is this a typo or does a second load of peanut butter go somewhere?
    I’m in the UK… Would the best Graham cracker substitute be our digestive biscuits?

  • These look so amazing! Thank you for sharing – I love how the cups poke out the top.

    Warm Regards,

  • Looks delicious!! Is the 3/4 cup peanut butter, melted and cooled just a duplicate ingredient? Is it supposed to be butter, maybe?

  • Hi Amy! Not dumb at all! You’ll want to eat them with they are thawed out. 🙂 -Jacki

  • OMG EMMA! These look incredible! I may or may not have drooled a bit at my desk…

  • Peanut butter cups are my FAVE!!! This might have to be my birthday cake next year.

  • My boyfriend would go nuts if he saw this! I love the chocolate and peanut butter flavor combo, but he goes bananas for it. I know what I’m making him for his birthday…
