These ridiculous chocolate bombs are a riff on my Gooey Chocolate Cookies, which just might be my favorite cookie recipe ever. I often make them for events or parties, and I like to play around and swap out the nuts and chocolate chips in the original recipe for other mix-ins like toffee bits, pretzels, or chopped candy bars.

I was doing one such swap a few weeks ago, tweaking the batter, adding peanut butter, and throwing in reckless amounts of mini peanut butter cups, when it occurred to me that other people might want to hear about these variations, and see some melty chocolate food porn of the highest caliber. Other people like you. So here you go, friends! A feast for the eyes and the tongue:

I could give you a long spiel about why I added peanut butter cups to the batter, and talk about the complex flavor interplay between chocolate and peanut butter, and you could all play Food Blogger Bingo and try to see how many buzzword I crammed into one overly flowery paragraph.

The truth, though, is that I was at Fresh & Easy and all of their tubs of mini peanut butter cups were on clearance, and I’m the kind of terrible shopper who will buy things that I don’t need because they’re a good deal, and who knows when I might really need several pounds of peanut butter cups, and won’t I be sorry if I need them later and they’re more expensive? So long story short, I ended up with 4 containers of totally unnecessary peanut butter cups silently judging me from the cupboard. Tell me I’m not the only person who does this.

So when we were asked to bring cookies to an event recently, I was relieved that I could put the cups to good use and feel like I had done a good thing, a Smart Budget-y Thing, by buying all that candy. And not only am I the best budgetary ninja ever, but I’m the best cookie ninja ever, because this peanut butter cup variation is amazing. Think about it: what could possibly go better with gooey chocolate than pockets of gooey peanut butter cups? Nothing, that’s what.

I’ve written the word “gooey” approximately three dozen times in the post, so it should be obvious that this is not a dessert for the thin & crispy cookie fans out there. This is for the people who chronically underbake their cookies, seeking that underdone texture that borders on raw cookie dough. These cookies seem sturdy enough once they cool, but when you bite into them, the firm edges yield to a soft truffle center that will make you question if the cookie will hold up in your hand, or if you’ll have to resort to shoveling it in your mouth with a spoon.

The batter is made with a high proportion of chocolate—heck, it’s practically all chocolate—so definitely use a chocolate you enjoy eating! No bargain bin chocolate chips, please. [But bargain bin peanut butter cups? Don’t mind if I do.] Bon appetit, my gooey chocolate-loving chums!

  • In a small bowl, whisk together the flour, baking powder, and salt, and set aside.
  • Combine the chopped chocolate, the peanut butter, and the butter in a microwave-safe bowl, and microwave in 30-second increments until completely melted and smooth. Stir after every 30 seconds to prevent overheating. Let the mixture cool to lukewarm.
  • Place the sugar and eggs in the bowl of a large stand mixer, and beat with a whisk attachment until thick and foamy, about 5 minutes. Add the chocolate mixture and the vanilla, and mix them in until they’re incorporated. Scrape down the bottom and sides of the bowl, as the chocolate has a tendency to sink to the bottom.
  • Stir in the flour mixture, and when that’s incorporated, add the miniature peanut butter cups, reserving about 1/4 cup of them. Press a layer of cling wrap on top of the batter and refrigerate it until it’s firm enough to scoop, at least 1 hour. (The batter can be refrigerated for several days, but it will need to sit at room temperature to become workable if it has been chilled for an extended period.)
  • Preheat the oven to 350 degrees F and line baking sheets with parchment paper. Use a large 1/4-cup scoop to scoop large portions onto the baking sheets. Cut the remaining peanut butter cups in half, and press a few of them on top of each cookie. Bake the cookies until they look dry and crackly on the top, but the center is still very jiggly and soft when pressed, about 12-15 minutes. Cool the cookies on the baking sheet—if you try to move them too soon, they’ll fall apart. Once cool, store the cookies in an airtight container at room temperature for 3-4 days. For the best taste and texture, microwave them for a few seconds before serving, so the centers get warm and gooey.

Recipe Notes

You can find miniature peanut butter cups at Trader Joe’s. You can also look for Reese’s miniature peanut butter cups at grocery stores, drug stores, or online at Amazon . Alternately, you can chop up large peanut butter cups and stir those pieces in instead.

Measuring Tips

Our recipes are developed using weight measurements, and we highly recommend using a kitchen scale for baking whenever possible. However, if you prefer to use cups, volume measurements are provided as well. PLEASE NOTE: the adage “8 oz = 1 cup” is NOT true when speaking about weight, so don’t be concerned if the measurements don’t fit this formula.

  1. I saw these on G+ and immediately jumped on over here.

    Oh. my. gosh.

    Incredible! And amazing pictures. Thanks for experimenting for us. 😀

    And a pound of chocolate in the cookies? Plus two cups of peanut butter cups? Bahaha. LOVE this!

    1. Haha, health food they are NOT. But at least you get some bang for your calorie buck!

      And isn’t G+ the best? I’ve found so many great food blogs and blogger friends through there!

  2. Made these last night and they were so good. My friends came over and devoured them. This recipe is definitely a keeper.

  3. I just recently cleaned out my baking cabinet and found many of these bags of bargain candy you speak of..oops! forgot about them!
    would you like my mailing address? to send these to me??

  4. This seems like a good reciepe to try so I am hope they turn out this is my first christmas baking cookies! It seemed a liitle intimidating but I managed. Just hope I don’t cause no sugar comas and or heart attacks cause I am making these as gifts for family and friends lol thank u 4 sharing! 🙂 happy holidays to u! Mwah! :-*

    1. Haha, I’ll keep my fingers crossed for no heart attacks or sugar comas! So glad the dough worked out, Lisa, I hope you love the cookies! Happy holidays to you too!

  5. I just made these cookies, and they are excellent! I made 1/4 of the recipe, and it made 8 decent sized cookies, baked at 350 degrees at 10 minutes. Thanks so much for the great recipe. The hardest part was waiting for the dough to chill for 1 hour 🙂

    1. Awesome!! So glad you loved them! I agree, I’m all about instant gratification, so the waiting is killer. 🙂

  6. My God. Looking at your pictures and reading “gooey” for the 26th time, my mouth just started a chewing motion! Even weirder I was craving a glass of milk! What sort of witchcraft have you done to me?!?

    Amazing cookies! I wish I could make them but we’re still sour from the news of my son being allergic to peanuts :-(. You’d think he was being held ransom the way we were cursing peanuts and the allergy gods.

    But anyway, maybe one day I’ll make a small batch. These look too crazy to not make them. And high freaking five on getting all those peanut butter cups on clearance! I swear you’re like my blogging spirit animal. I don’t judge you at all!
