Chocolate Stout Cupcakes with Peanut Butter Buttercream

As I stated before, the “chocolate stout” cake/cupcake is my favorite as far as chocolate goes. It’s so effing delicious. So this is a quick variation from the Irish Car Bomb cupcakes I made a few weeks back. This time, we’re using peanut butter 😉

I’ve tried a few peanut butter buttercreams, and the most popular one online is from Ina Garten. I love her, she’s one of hands down favorites on The Food Network, but I’m not feelin her peanut butter frosting. I mean, it’s not disgusting at all. It’s delicious, but it’s just too “peanutty” for me, if that makes any sense. To me, it tastes like peanut butter taken out of the jar and slathered on a cupcake. I didn’t fall in love with it, so I kept looking for a lighter one that would give me just enough peanut butter flavor without being too heavy. I found this recipe and saw that it was adapted from the famous Baked cookbook, so knew I had to try it. Unlike Ina’s recipe, this one uses less peanut butter, so it’s milder and easier to eat without feeling like you just swallowed a sock.

Chocolate Stout Cupcakes with Peanut Butter Buttercream

The chocolate stout cupcake recipe makes about 24 (or 2 dozen) cupcakes, and this peanut butter frosting recipe says it’s enough for 24 cupcakes but I found that to be false if you’re using a piping bag and decorative tips. Maybe if you were just slathering it on with an offset spatula, you’d have enough, but I had to add an additional cup or so of powdered sugar just to make it stretch. The good thing about this recipe is that it is customizable, so if you need to add another cup of sugar, it won’t really affect the outcome. Just play around with it, but always start with the smaller amounts first.

The actual cupcake is insane, trust me on this. It’s fool proof and easy to do, and sooo chocolatey without being too sweet or artificial. I have a lot of leftover Guinness in my fridge, so I’ll be busting out different chocolate cupcake variations over the course of the next month or so.

Feel free to top these cupcakes with Reese’s miniature cups, or Reese’s Pieces…or even stick a tiny pretzel thru it, it’ll be delicious. Enjoy 🙂

    Resha,
    I tried the peanut butter buttercream frosting recipe along with my own chocolate cake recipe. My youngest brother, who is a peanut butter and chocolate fanatic, told me that it was the best cake that he ever had. My mother-in-law, on the other hand, didn’t care for the peanut butter frosting. It was just too peanut-butter for her. I might use a 1/3 cup next time I make the frosting. Also, for those of you that may have had difficulty scraping the peanut butter from the measuring cup, try spraying it first with cooking spray. Worked like a charm for me. Thanks for the recipe!

    Hey Resha, Do you think unsweetened cocoa can be used instead of the Dutch process cocoa powder?

    • admin says:

      no. there are stark differences between regular unsweetened cocoa and dutch processed cocoa. i know it’s confusing, but it’s good to keep both on hand. i buy my dutch processed cocoa from King Arthur Flour. it’s like $10 for a pound, and it’s incredibly good stuff, just in case you can’t find it in the grocery store (because my local Wegman’s doesn’t seem to carry dutch processed…womp)
