I’ve been trying to get my brain around the idea of peanut butter and jelly cupcakes for awhile now. I’ve agonized over the hows and whys in my mind–where the jelly would go, what kind of jelly I would use, what flavor of cupcakes, yada yada yada. And then, out of nowhere as I was lying in bed awake and hungry, the simple solution came to me: why use jelly when you can use chocolate? I think that rule can pretty much be applied to all areas of life. Honestly, I’m kind of shocked it’s taken me this long to come up with this one–it’s not like no one’s ever put peanut butter and chocolate together.

I really am not  much of a semi-homemade kind of girl–I really do make almost everything from scratch. But when it comes to cupcakes, doctored-up cake mix cupcakes really are my favorite way to go. They’re quick, easy, delicious, and fail-proof, regardless of elevation, humidity, or political affiliation. My only snobbery when it comes to doctoring up cake mixes is that I will only use Duncan Hines cake mixes (and they don’t even pay me to say that…in fact, I’m pretty sure I’ve never had a conversation with anyone affiliated with Duncan Hines). You’ll need a white or yellow Duncan Hines cake mix as well as canola oil, 3 eggs, sour cream, vanilla, small Reese’s Peanut Butter Cups, and peanut butter.

Preheat your oven to 350 and line 2 12-opening muffin tins with cupcake liners. Set aside.

Combine all the ingredients except the peanut butter cups in a large bowl and beat with an electric mixer on medium-low for 30 seconds, scraping the bottom and sides often, then beat on high for 3 minutes.

Fill each cupcake liner about 1/3 full with cupcake batter. Top with an unwrapped mini Reese’s Peanut Butter Cup,

and then top the Peanut Butter Cups with the remaining batter. You want to make sure that the candy is covered and the liner is about 3/4 full.

Bake the cupcakes in the preheated oven for 18-22 minutes or until they are golden on top.

Remove them from the oven and let them cool completely.

While the cupcakes are cooling, you’ll want to get the frostings ready. Yep, that would be “frostings.” Plural.  It’s hot and Friday and the end of summer and your kids are fighting–I promise, you need frostings. For these cupcakes, I used the peanut butter frosting from these cookies and then the chocolate frosting from the infamous Tim Riggins Brownies.

Why that chocolate frosting, you ask? Mostly because between that frosting, this one, and this one, Mr. Riggins’ frosting is the quickest, easiest, and I always have those ingredients. Plus, the Old-Fashioned Chocolate Frosting is awesome, but it totally deserves to be the star of its own show rather than in an ensemble production, you know?

When the cupcakes have cooled completely, use this tutorial to frost your cupcakes. Squeeze a dollop of remaining frosting onto your finger, lick it, and ponder the wonder of the forthcoming school year, then pour a few glasses of milk and watch your kids ponder the wonder of you and your awesome cupcakes.

    I actually made PB & J cupcakes for my son’s second birthday this year. They were really tasty! I made a basic vanilla cupcake, took out a core of it, and put a dollop of grape jelly in the center(I bought the squeeze bottle, low sugar kind and it worked excellent!),replaced the core, topped with pb frosting. I made a little well at the top of my frosting to put another small dollop of jelly so that you could tell what kind of cupcakes they were.

    They weren’t anything too special to look at, but they tasted really good. In fact, I got a lot more compliments on them rather than the “hot fudge sundae” cupcakes I made, which looked a lot cooler, but didn’t have as special of a flavor. 🙂

  5. 5

    I, too, have been trying to come up with an idea for PB & J cupcakes. In my mind what I’d do is have jelly-filled vanilla cupcakes with peanut butter frosting. But of COURSE peanut butter and chocolate is even better (writes the lady with chocolate-PB brownies cooling in a pan). 🙂

      Ang says:

      I’m having a hard time wrapping my head around these because of the peanut butter and jelly muffins I made – peanut butter batter with a dollop of strawberry jam baked inside. Those were greasy and slight salty and quite unlike these in every way. But when I force myself to forget those…let’s just say I wish my husband (and therefore children) were bigger chocolate-and-peanut-butter fans, because these would be so much fun to make!

    Kelli says:

    My mouth watered when I saw the name of this recipe and it’s perfect timing because my husband’s birthday is right around the corner and guess what his favorite candy is?

    I have one change; I am a mad addict of the dark chocolate reese’s. I found the minis a little while ago and horded them like a crazed squirrel so I could chunk them in the food processor and mix it in place of the cadbury eggs in your cadbury egg cookies, which happens to be a family staple. I think I’m going to put those in there.

    But anyways, the real point to my comment…let’s say someone can’t have sour cream (someone who strangely resembles me). What would you suggest as a substitute?

My husband LOVES peanutbutter and chcolate. I may have to make them with a chocolate cupcake batter though 😉

    Mindi says:

    These sound delicious, but I always try to substitute healthier options if I can (I know they are cupcakes, so essentially unhealthy, but I try…). So can you use plain yogurt in place of the sour cream? And why do you only use duncan hines?

  14. 14

    Mindi, you can totally use plain yogurt–I’d recommend high-quality fat free plain Greek yogurt (I’m not impressed with the Yoplait or Dannon Greek yogurts).

    As far as Duncan Hines goes, I’ve just found the cake mixes from Betty Crocker and Pillsbury to both be dry and flavorless, even when they’re doctored up. When you doctor up a Duncan Hines cake mix, it ends up tasting and feeling like something from a high-end bakery.

    These look so good. At first I read it as: Top with an UNWANTED mini Reese’s Peanut Butter Cup, and I was thinking What??? Who would not want a Reese PBC?

      Jennifer says:


      I am gluten intolerant, lactose intolerant, and cant have chocolate. I have gluten free white cake mix (found at the store), I cant do the candy center but I can do the PB so I think Im going to use Skippy’s honey nut PB (gluten and dairy free) to flavor the frosting, and a friend told me that Carob kinda tastes like chocolate, so I am going to try some carob in the cake. I believe there is some sourcream/ yogurt that is lactose free check in the organic/health food section of your local grocery store? If I cant find some Im either going to just follow package directions for the gluten free cake mix OR just use greek yogurt and take a chewable lactaid pill lol

    Courtni says:

    I saw the blog for these, and made them the next day! They were a huge hit with everyone that tried them. However, I was hoping that my frostings would have been fluffier, I may have done something wrong. I think that my butter may have been too hot when I added it to the chocolate frosting??? It looked almost like a thick ganache.I also sifted my powdered sugar onto my food scale to reach half a pound. There wasn’t nearly as much as there was peanut butter frosting, the peanut butter frosting was fluffier, but was really glossy, I live in the South so I wonder if the humidity affected it? I like to follow a recipe exactly the first time, or two, and I almost always give a recipe a second (or third) chance. Practice makes perfect, right? 😉 I didn’t have time to swirl the frostings like I would have liked to, but I spread the peanut butter on the cupcakes, and dolloped the chocolate on top. I love your cookbook and blog, I love to cook anyway but with a new baby it was hard to get the motiviation, well, you’ve provided it! I have tried more of the recipes from your cookbook than from any other cookbook that I have so far, I have been inspired to grill more! Thank you, it’s great to see how much you love cooking.

Any suggestions?

Thanks for the recipe – we can’t get enough PB and chocolate around here!

      Okay. This is where we might get bludgeoned by the hard-core foodies, but Sara and I use salted butter nearly exclusively. Generally, especially in baking recipes, I just decrease or omit the salt that I add. But I used salted butter in this recipe and I was not sad about it at all. 🙂

Last month I was in charge of making the cake for my friend’s birthday and I was coming up with different ideas to incorporate the pb frosting . . . then it finally hit me (in a dream of course). I call it reeses cake, it was amazing! I made a chocolate cake from a box, let it cool, cut each round in half, and filled all the layers with pb frosting. Then I whipped up a super yummy chocolate pb ganache and poured over the top. When it was almost cooled (but still a little gooey), I put crushed reeses pb cups on top. It was divine! Thanks for the inspiration, my friend was over the moon! xo
