Chocolate Peanut Butter Cupcakes
Chocolate and peanut butter are such a classic flavor combo. You really can’t beat it. I’d say it’s definitely one of my favorites.
This peanut butter frosting recipe is amazing. No wonder it’s famous. I decided to make these on a whim and take them to a cookout.
I got inspiration from Mermaid Sweets. I decided to kick it up a notch by filling the cupcakes with more peanut butter cup pieces and some ganache. Because ganache definitely makes everything better! Be warned though, after one of these guys, you’ll definitely need a glass of milk.
For the chocolate cupcakes, I used the recipe from Elisa Strauss’s Confetti Cakes for kids – I’m not going to post the recipe here, I recommend the cookbook, although I’m sure someone else has posted the recipe on the Internet somewhere…
Kathleen’s Peanut Butter Icing – as seen on Mermaid Sweets from the Food Network
1 cup confectioners’ sugar
1 cup creamy peanut butter
5 tablespoons unsalted butter, at room temperature
3/4 teaspoon pure vanilla extract
1/4 teaspoon kosher salt
1/3 cup heavy cream
Place the confectioners’ sugar, peanut butter, butter, vanilla, and salt in the bowl of an electric mixer fitted with a paddle attachment. Mix on medium-low speed until creamy, scraping down the bowl with a rubber spatula as you work. Add the cream and beat on high speed until the mixture is light and smooth.
Chocolate Ganache (I had some leftover in the fridge, you would probably only need about 1/4 of this recipe)
3/4 cup semi-sweet chocolate
3/4 cup bittersweet chocolate
1/3 cup heavy whipping cream
In saucepan bring whipping cream to boil over high heat.
Pour hot whipping cream over chocolate and stir until chocolate melted.
You can add more cream if your ganache is too thick to spread.
To assemble the cupcakes:
Using the cone method, remove some of the cupcake and set aside. Drop a few pieces of cut up mini Reeces peanut butter cups to the hole in the cupcake. Spoon some ganache in the hole.
Replace the top of the cupcake. Frost with peanut butter frosting (I used my Wilton 1M tip). Top frosting with more cut up mini Reeces peanut butter cups.

loving the baileys idea! mmmmm
I use the same recipe (I think, I’ve had it for years; a standby. I think it was called “Chocolate Fudge Frosting”)
Best thing EVER to do? add a bit of mint extract – it’s very easily my most popular cake filling.. and my favourite icing to eat by the spoonful lol.
I haven’t found the perfect chocolate frosting yet, so I’ll definitely have to try this one!
i definitely, definitely have to try this soon. i can’t get enough of chocolate!
It’s funny about the no milk thing…I was making a new martini recipe that was super strong, so I thought cream would help it become drinkable – but I had no cream, but I did have Vanilla Caramel Coffeemate…it was great!
Ironically, I almost never have milk and always have Bailey’s. Go figure.
Sometimes you really do need a seriously dark chocolatey frosting. This looks absolutely ideal.
you really got into the food styling there — cute pic with the cupcake in the sprinkles.

This sounds nice – I’ll have to try it one day! Jen, have you tried King Arthur Flour’s Supersimple Chocolate Frosting recipe? It is my favourite recipe (so far) for chocolate frosting – I’d definitely recommend it!
(Sheesh! deleted to fix a typo! Wish there was an edit function :))
Pegster – I have not tried the KA recipe. It looks similar to this chocolate frosting recipe which is delicious!
The think I love about this frosting is the stiffness and the fudgeness.
I like this frosting for when I want something quick. Otherwise, I like to use frosting that involves melted, good chocolate for those special occasions. YUM! I would gobble up your cupcakes in a second.
Great call on the Bailey’s – my mom would love that icing. I am going to try this next time I make cupcakes.
I would never think to sub bailey’s for milk. Brilliant. I love my chocolate desserts to be super chocolaty – this looks great!
LOVE the super pink sprinkles too. So pretty 😀
Oh, I forgot to mention that I’m hosting a giveaway. I wonder if it would come handy in this baking project…
These look great!! I love your photos!! I’ve been searching for a good chocolate-y frosting and I think I might try this!!
Would you mind checking out my blog? 😀 http://ajscookingsecrets.blogspot.com/
I could have definitely used this recipe for my sourdough chocolate cake this week

i just made this frosting today to go inside some cupcakes using your cone method. and i topped with vanilla buttercream, at my hubby’s request.
let me just say this was so delicious i had to take my whitening strips out early so i could lick my fingers, and then the bowl. then my 15 month old attacked me to lick the spatula. we were all sugar high and happy before dinner.
my hubby said “every day i am happier i married you because of things like this”
Thanks for sharing this recipe!!!
Kris – I love hearing comments like that! Thanks for trusting my recipes enough to try on your hubby!
Mmm this looks fantastic, though the ingredients look similar to another delicious recipe I’ve used before that is pretty soft. I’m guessing it’s the butter temperature. Should it be room temperature here? Thanks!
You definitely want your butter at room temperature so it creams nicely.
I have the Bailey’s..lol but I’m out of cocoa powder. Have you ever tried subbing it with melted chocolate? And if so how much do you use?
Best frosting ever. Perfect taste, texture and color. It was divine. I will never use another chocolate frosting recipe ever again. Thank you very, very much! It is truly a gift. 🙂
Jen,
I am a person who has been cooking from the age of 5 ….lol now i have certin likes loves and disliks lol however i found a revepie i wanted to make and it called for a fudge type frosting…. knowing i didnt have one i liked for this so i started looking friday night and didnt come across your recepie until saturday morning so i got out my ingreadience.. but i didnt have Balies or white milk i had some Cream de Mint and Choc. Milk so i straied a tad from ur recepie …. i used 1/2 stick of butter, and to get 1/3 cup of liquid i used aprox 1/4 cup of Cream de Mint and the rest Choc. Milk. Plus the res of ur ingreadience …..omg this is the best dark choc fudge frosting ive ever had!!!! And i used the best dk. Cocoa i know of !!!!!! Thankyou thankyou THANKYOU!!!!!!!!!!!!!
I’m a baker and for the life of me I can’t find a thick chocolate fudge frosting. Is this frosting thick? I don’t want anything too creamy, like ganache when you let it sit. Help please!

This frosting is definitely thick. You can see in the pictures that it held up nicely to piping. It’s not as creamy as a ganache.
Thank you for responding! 🙂 I see that some people use melted chocolate instead of cocoa powder. Doesn’t it really matter?
beantownbaker — February 5th, 2013 @ 10:13 am
For this recipe, I always use cocoa powder.
If I make these the day before do I have to refrigerate them(since the recipe calls for milk)or can I leave them on the counter covered?
beantownbaker — October 30th, 2013 @ 8:21 pm
You can leave them on the counter. The milk in the frosting stabilizes so it won’t go bad. I’d put them in a covered container though.
Hi. Is the butter you use salted or unsalted?
beantownbaker — December 26th, 2013 @ 11:01 am
I always use unsalted butter unless specified as salted butter.
This is absolutely THE BEST chocolate frosting recipe I have EVER tried. I used it to frost some homemade vanilla mint cupcakes and topped them with an Andes mint for my daughters sweet 16 party. I had complete strangers tell me I need to open up a bakery and sell nothing but those cupcakes! Thank you so much for posting this. It is truly amazing.

SO glad you enjoy this recipe! Nothing beats a great chocolate frosting.
I can’t wait to try this! I LOVE the flavor of the hersey’s dark choc frosting recipe but its so thin that i can’t use it for cupcakes, only for a cake. I even tried refrigeration overnight to see if that would thicken it up and it didn’t. so i can not wait try to this one for my cupcakes!
beantownbaker — April 27th, 2014 @ 2:53 pm
I agree. The Hershey’s one is just too thin for cupcakes.
I made a variation on this recipe for my daughter’s birthday cake yesterday and it was fabulous!
I’m still trying to figure out how 6T butter is enough though–I ended up putting in two whole sticks of butter and adding in the milk after the first addition (I added it slowly) of powdered sugar/cocoa combo–it was so thick and dry that my mixer was making new, horrible noises and I was sure it was going to die! LOL
