Chocolate Peanut Butter Cup Cupcakes with Peanut Butter Frosting

Chocolate + Peanut Butter 

The rich, silky, sweetness of chocolate combined with the smooth, creamy, subtly sweet & nutty peanut butter: well, it’s simply, a match made in heaven. Try to tell me any other combination that is more delicious and I’ll call you crazy (unless, that is, you say chocolate + caramel – then you’ll have a good argument.)

I’ve been thinking about this delicious combo for days now, but today was the day to make things happen.


There really are no words to describe just how decadently delicious these cupcakes are. The richness of the chocolate cake makes for a perfect balance with the sweetness of the peanut butter frosting. Oh yeah, and the surprise filling isn’t too shabby either. 😉


Chocolate PB Cup Cupcakes with Peanut Butter Frosting

(Makes 24 cupcakes or 12 jumbo cupcakes)


-1 box Devil’s Food cake mix

-1-1/4 cup water

-1/2 cup applesauce (or oil)

-3 eggs (*I used 1 egg + 1/2 cup egg substitute)

-1 small bag Reese’s peanut butter cups, unwrapped

-Peanut Butter Frosting (see recipe below)


Mix cake mix, water, applesauce (or oil) and eggs according to directions on box (2 minutes on medium speed with electric mixer). If you’re feelin’ crazy, toss in some chocolate chips like I did. Because really, when has extra chocolate ever been a problem? 😉


Fill muffin pan with liners, and fill liners 2/3 full with batter. Bake according to directions on package (350 degrees for 18-20 minutes). Allow cupcakes to cool for about 10 minutes, then gently press one peanut butter cup into each cupcake. Don’t worry about what they look like, since you’ll be frosting them anyways.


It’s important to put the PB cups in while the cupcakes are still somewhat warm; that way, they’ll get slightly soft and melted. You’re going to want to dig right in once you see things getting all melted and delicious, but I promise, it’s worth the wait for the frosting.


Once cupcakes are cooled completely, it’s time to get them “dressed” with some PB frosting:

Peanut Butter Frosting

(Enough to frost 24 cupcakes or 12 jumbo cupcakes)

-1/3 cup smooth natural peanut butter

-3 cups powdered sugar

-1-1/2 tsp. vanilla extract

-1/4 cup milk (plus more to achieve desired consistency)


Blend peanut butter, vanilla, and powdered sugar until combined. Add milk and mix on medium speed until smooth and creamy. Continue to add milk until you get the desired consistency.

After frosting the cupcakes, top each cupcake with some extra peanut butter cups chunks & a dusting of cocoa powder, if desired.



Rather than making 24 regular-sized cupcakes, I made 14 regular sized + 6 jumbo cupcakes.



Surprise PB Cup filling! :)



I’m telling you: If you’re as much in love with peanut butter + chocolate as I am, then you need to try these cupcakes. Your friends will thank you.

  2. Jen says

    Look amazing!! I make something very similar – look for me on Facebook – add me and I have a whole baking album! :) oh it’s Jen Rosenthal

    I’m crying right now that I don’t have a stand mixer OR a hand mixer right now….you’ve got me in my “domestic” phase, where all I want to do is bake all day

  4. says

    I need one of these asap! Definitely will be giving them a try, as I truly believe peanut butter and chocolate were destined for each other.

    I don’t like this blog! Do ya want to know why? . . .
    I’m staring down photos of chocolate/peanut butter cupcakes and thinking to myself, “two years ago, I might have had a chance to try one of these babies. . . Now all I get to do is look at them”.


    Great job! I think you’ve found your calling.


    P.S. We miss you.

    Ummm, how on earth do your cupcakes come out as pretty as they do. Mine are always a hot mess! lol. You should definitely open up a bakery. People would come far and wide (ahem Boston…just sayinn) for your treats :)

    So creative! I make these sugar cookies that Keith loves. I put a thin mint in between 2 slices of raw sugar cookie dough. Seal the edges and then bake in the oven. So good!!!

    Ok – so the Strawberry Filled Lemon Cupcakes were a huge hit at the office bday (many props to you!). Thanks again for your encouragement.

    I have been elected to bring in cupcakes again next month for my boss’s bday. I’m thinking of trying out these chocolate peanut butter delights.

  9. Melissa says

    I have been demanded by management at work to make some cupcakes for tomorrow. I am the team baker, so I am making these! Thanks for the recipe!!!

      • Melissa says

        THEY TURNED OUT FANTASTIC!!!!! My tummy hurts from eating all the peanut butter cups. LOL Now, I want to master the key lime cup cakes I had from Betty’s Cupcakery…any idea on what the heck is in the icing??? That will be my weekend project.

  10. says

    Hmmm, I didn’t try them, but probably something simple to start, like a little lime zest/juice. Then dye it green to give it a little more “lime” feel. :)

  11. Krysten says

    I made these cupcakes last weekend for a cookout and they were a huge hit! One question for you though, how do you make your frosting look so gorgeous!? Every recipe I see you make has beautiful frosting- I can’t manage to get mine to look like that! Maybe you could do a frosting tutorial?! Or just give us some tips :) Anyway, great recipes, love the blog!

  12. says

    OH my, oh my, oh my!!!!!!!!!!
    Ok, I can tell already I’m so going to have to limit my reading of your blog! LOL I’ve gained 10 lbs just reading all these amazing recipes and sweets are my biggest downfall!!!! If I could just figure out how to eat these in normal quantities instead of making myself sick I’d be fine!

    These are a keeper.. but again… I’m so gonna have to pick the right time to do this! Girl, your “work out” section must be something like “Run 30 miles, 6,000 sit ups & 500 push ups” as a “warm up”!? Or are you just blessed with the ability to eat these sweets without the ease off adding inches to your waist size? *sigh*

    • says

      Hahaha, I’m so glad you’re excited to try them!
      No, I don’t have any crazy workout sessions…I just enjoy a few then give them away to other people so I’m not tempted to eat the whole batch (which I EASILY could!) 😯
