Dark Chocolate Cupcakes with Peanut Butter Frosting

Dark Chocolate Cupcakes with Peanut Butter Frosting

I have a secret that I’m about to blab. It’s about me. And it’s a doozie. It’s going to rock your world…

I don’t really like cake…

Shhh…

Can you believe it? It’s the truth. Hard to fathom, with all those cakes that I decorate. Now, don’t get me wrong. I will eat cake. But it pretty much ranks at the very, very bottom of the dessert hierarchy for me. Given options, I would choose pretty much anything over cake. Now, if you’re talking cheesecakes, flourless chocolate cakes, coffee cakes, crumb cakes, and things of that nature, well then that’s a whole different ballgame. But regular cake? Like birthday cake-cake? Meh. It’s just never really been my cup of tea. But what I do love is frosting. And phenomenal frosting can absolutely make my day. Peanut butter or cream cheese frosting? It may as well just be Christmas. As a result, I love cupcakes because I can pile them sky-high with dreamy frosting and enjoy each and every bite. These dark chocolate cupcakes are a dream come true for anyone who is a cake or frosting lover – they are truly the best of both worlds.

Dark Chocolate Cupcakes with Peanut Butter Frosting

These cupcakes are insanely rich and moist, and are made using the same type of method used for making brownies – melted chocolate is added to a whisked mixture of eggs and sugar, and then flour is stirred in. The resulting batter almost resembled a mousse; both thick and light. It creates incredibly moist cupcakes that also have a light and fluffy texture.

And the frosting. Oh the frosting. Bestill my heart. I have been using this recipe for a couple of years now (how has it never made it on here before?!), mostly as a filling for chocolate cakes. But on top of cupcakes? Where I purposefully try to create a 2:1 frosting to cupcake ratio? A-MAZING. I cannot make this without usually ending up with a stomach ache from nibbling out of the bowl one too many times. It’s irresistible. Sometimes I’m tempted to make it to just have. Smeared on toast? Used as a dipping vessel for bananas or apples? So many possibilities. The “secret ingredient” in this frosting, just as in the Easy Vanilla Bean Buttercream, is the heavy cream. It creates a smooth and fluffy frosting that is easy to slather or pipe on.

Note: To make the swirls of icing, I use a 1M icing tip. I just love the look that it gives the cupcakes; it reminds of a soft serve ice cream cone. Which is another one of my favorite things :)

Dark Chocolate Cupcakes

Yield: 12 cupcakes

Prep Time: 30 minutes (active), 45 minutes (inactive)

Cook Time: 18-20 minutes

Total Time: 50 minutes

Ingredients:

For the Cupcakes:
8 tablespoons (1 stick) unsalted butter, cut into 4 pieces
2 ounces bittersweet chocolate, chopped
½ cup (1.5 ounces) Dutch-processed cocoa powder
¾ cup (3.75 ounces) all-purpose flour
½ teaspoon baking soda
¾ teaspoon baking powder
2 eggs
¾ cup (5.25 ounces) granulated sugar
1 teaspoon vanilla extract
½ teaspoon table salt
½ cup (4 ounces) sour cream

For the Peanut Butter Frosting:
1 cup confectioners' sugar
1 cup creamy peanut butter
5 tablespoons unsalted butter, at room temperature
¾ teaspoon vanilla extract
¼ teaspoon kosher salt
⅓ cup heavy cream

Directions:

1. To make the Cupcakes: Adjust oven rack to lower-middle position and preheat to 350 degrees F. (If you are using a non-stick muffin pan, heat the oven to 325 degrees F.) Line standard-size muffin pan with baking cup liners.

2. Combine butter, chocolate, and cocoa in medium heatproof bowl. Set bowl over saucepan containing barely simmering water; heat mixture until butter and chocolate are melted and whisk until smooth and combined. (Alternately, you can microwave the mixture at 50% power, stirring every 30 seconds until completely melted.) Set aside to cool until just warm to the touch.

3. Whisk flour, baking soda, and baking powder in small bowl to combine.

4. Whisk eggs in second medium bowl to combine; add sugar, vanilla, and salt until fully incorporated. Add cooled chocolate mixture and whisk until combined. Sift about one-third of flour mixture over chocolate mixture and whisk until combined; whisk in sour cream until combined, then sift remaining flour mixture over and whisk until batter is homogeneous and thick.

5. Divide the batter evenly among muffin pan cups. Bake until skewer inserted into center of cupcakes comes out clean, 18 to 20 minutes.

6. Cool cupcakes in muffin pan on wire rack until cool enough to handle, about 15 minutes. Carefully lift each cupcake from muffin pan and set on wire rack. Cool to room temperature before icing, about 30 minutes.

7. To make the Peanut Butter Frosting: 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.

    Hi, I know this was from a while back but found your recipe on pinterest. I made these tonight and Holy Hell! De-licious. Will definitely be making these again:)

    I’m always searching the web for juicy, delicious recipes. Usually I just dribble over gorgeous pictures and imagine the smells and tastes, but never actually makes anything. (A bit lazy, but also not too much time as I am having a baby around..) But – I found your blog and these cupcakes, and I HAD to make them. I got a major craving! (Breast-feeding does that to you, apparently. Gives you cravings, that is.)
    Then, I’m Norwegian – so we don’t have the same stuff as you do (i.e. butter in sticks, different cocoa powder etc.) and my head doesn’t understand anything that isn’t metric, but after some googling I found more or less everything and got it all converted.
    In addition to this, my husband is allergic to gluten. And they came out just PERFECT! My blender-thingy didn’t manage to make the peanut butter all creamy, but I loved the bits of crunchiness (couldn’t make those beautiful swirls, though) .
    So: Thank you for sharing this wonderful recipe!

    After reading all the reviews, I made a few adjustments. First I whipped my eggs,sugar,vanilla and salt in my KitchenAid. This made the batter very fluffy. I also added more flour. Probably 1 cup total. I think because I whipped my eggs with my KitchenAid it made my batter go farther. I had enough to make 10 additional mini cupcakes. The next huge adjustment….I cored the center out and put ganache in…oh sweet heaven did that just make the cupcake!!! Thank you for this recipe! These are my birthday cupcakes this year and I feel every year from now on :)

    I haven’t tried the cupcakes, but this is my go-to peanut butter frosting recipe. It’s got a wonderful peanut butter flavor but it’s so light and whippy. I always get compliments when I use this recipe. Thanks so much for sharing it!

    Oh my, these are the best cupcakes, hands-down, ever. I made them to send to a sports fundraiser (which I did not attend), and heard from attendees that they were quite sought-after. My 17-year-old son said the one he ate “was the best cupcake he’s ever eaten,” and the kid doesn’t hand out food compliments all that readily. Since I couldn’t fit two dozen in the box to send, some stayed home. They are difficult to avoid. Wait, that’s not quite right–they are IMPOSSIBLE to avoid. In fact, I think I hear the last one calling to me now…

    Thanks for sharing this delectable recipe!

    Is this recipe suited for high altitude?

      Unfortunately, it is not. I bake at a pretty low altitude, so if you are at a high altitude, you should make appropriate adjustments.

    Could I substitute bittersweet chocolate with semi-sweet chocolate? If I do would I have to reduce the amount of sugar, or would it not be that much of a difference? I don’t particularly like dark chocolate, so can I change it with semi-sweet chocolate, and it’ll still come out delicious?

    Was seeking an Italian dressing recipe.
    Your mom’s caught my eye. I was reading your blog about it, and found myself distracted by THIS recipe at the right of the screen. It’s like mandatory that I make chocolate cake with peanut butter frosting for my husband’s birthday. I recognized the tantalizing swirl of p.b. icing atop these cupcakes easily. I think I should do a practice run with this recipe…My husband’s birthday isn’t until November! Oh, but hey! Our anniversary is this week! How’s THAT for a good excuse?! AND I have chocolate…er…brown eyes too. : ) Great website, great recipes I’ve seen thus far. Thanks!

    Is it possible to make frosting without a mixer? I’m too afraid to try because the consistency of the frosting mixed by hand might not be the same… & I’m not sure my mom wants to buy a mixer

    • Michelle on June 21st, 2014 at 6:55 pm

      Hi Ysabel, I’ve honestly never made a frosting by hand, and I’m not sure how well the powdered sugar would be incorporated with just a whisk or wooden spoon.

    Hi Michelle,
    Yay! I just discovered your blog.
    I’m planning to make the Dark chocolate cupcakes w/ PB frosting for July 4th!
    Please tell me, what brand PB do you use?
    My usual is “smart balance” it has oil separation & natural.
    Should I use a stable brand like jiffy! Or what?
    My muffin pan is non stick but I always use liners anyhow, what temp should I use?

    Reply

    • Michelle on June 26th, 2014 at 10:48 am

      Hi Linda, I use Skippy brand peanut butter for baking. Using natural peanut butters for baking is not a good idea, as the excess oil can affect the final result. As for temperature, if your non-stick pan is dark, then reduce the temperature by 25 degrees.

    Michelle,
    I absolutely love the way your “frosted” PB cupcake looks, it’s the perfect professional finish. Please share tips on how to achieve it. Maybe a tutorial? ;)
    I will purchase the recommended tip & bag to frost.
    Thanks!

    Michelle thanks so much for your direct reply.
    Please explain/ clarify on the type & size of frosting tip you used.
    I’m about to shop for tips, a first for me, and want be sure to buy exactly what you’ve used since it looks gorgeous!
    No where on youtube tutorials did I hear mention of a 1M frosting tip??
    What brand, type, and size is yours??
    Have a great day & thanks!

    I always read the reviews on a recipe before I try it! There are usually some helpful tips, however when I was reading through this recipes reviews I was concerned that most of them were praising the frosting and making no mention of the cupcakes. (There was someone that commented that the cupcakes were too bitter) but, because my cousin had sent the recipe, I decided to give it a try… What was everyone thinking??? These are the best chocolate cupcakes I have ever tasted! Wow, they are so moist and flavorful, they don’t even need frosting! And putting peanut butter frosting on them… Ingenious! Thank you in advance from all of my Mothers Bingo group! They are going to LOVE them…

    Would the frosting turn bad if I leave these out? Like not put them in the fridge I mean. I was going to bring these to a gathering and I’m making it a day before but I’m afraid that if I put it in the fridge after making these, when I take it out the frosting will melt if I leave it out for too long. What should I do?

    • Michelle on September 2nd, 2014 at 2:56 pm

      Hi Sam, As long as your house is temperature controlled and not too hot or humid, these will be fine at room temperature (up to about 72 degrees F). Enjoy!

    Hi Michelle

    I did send you an email question but thought I had better ask here as it is a recipe question Please just ignore email question. :)

    Can I use Self-raising flour as I don’t want to purchase in all purpose and self-raising as they will go bad before using both. I am making something else for my birthday as well as these cupcakes.

    I will obviously leave out baking powder and salt but leave in the baking soda as it starts working at a lower temperature.

    Many thanks!!

    • Michelle on September 17th, 2014 at 9:20 am

      Hi Maggie, I would not recommend using self-rising flour. Flour typically does not go bad for a long, long time and you can store it in the freezer to increase its longevity.

      Hi Astrid, Yes, it will make double the number of mini cupcakes, and you will need to reduce the baking time.

    Hi Michelle, I brought these to work for a co-worker’s birthday and they were a huge hit! The frosting is just right, not too sweet. For the co-worker’s birthday, I wanted to try a new cupcake recipe, but everyone is demanding this one again!
    Question for you: Do you always use all-purpose flour in your cupcakes? Do you ever use cake flour?

      Hi Jenny, I don’t typically use cake flour because it tends to make them too light and crumbly.
