  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/3 cup (80ml) vegetable oil
  • 1 cup (200g) granulated sugar

  • Optional: crushed Reese’s Pieces – Because, why not?!

How to Make Dark Chocolate Cupcakes with Peanut Butter Frosting: Step-by-Step

Okay, here we go! Time to turn those ingredients into something amazing. Don’t worry, I’ll walk you through it. These dark chocolate cupcakes with peanut butter frosting are easier than you think!

Making the Dark Chocolate Cupcakes

  1. First things first: Preheat your oven to 350°F (177°C). Get your muffin pan ready with cupcake liners. I like the cute patterned ones, but plain is just fine too!
  2. Now, in a bowl, whisk together the flour, cocoa powder (that Hershey’s Special Dark!), baking soda, baking powder, and salt. Just whisk it all up until it’s combined. Set it aside for now.
  3. In a *separate* bowl (very important!), whisk together the oil, sugar, egg, vanilla, and buttermilk. Get it nice and smooth! Then, add in those dry ingredients we just mixed.
  4. Here’s the magic: Pour in the hot coffee (or hot water). It’ll seem thin, but don’t panic! Just whisk it all together until it’s *just* combined. Don’t overmix!
  5. Carefully pour the batter into your prepared cupcake liners, filling them about 2/3 full. This is important – don’t overfill, or they’ll overflow!
  6. Bake for 20–22 minutes. To test if they’re done, stick a toothpick into the center. If it comes out clean, they’re ready!
  7. Let the cupcakes cool in the pan for about 10 minutes, then transfer them to a wire rack to cool completely. And I mean *completely*. Frosting warm cupcakes is a disaster waiting to happen!

Preparing the Peanut Butter Frosting

  1. Once your cupcakes are *totally* cool, it’s frosting time! In a large bowl, beat the softened butter until it’s nice and creamy.
  2. Add the peanut butter, confectioners’ sugar, heavy cream, vanilla, and salt.
  3. Beat it all together until it’s light and fluffy. If it’s too thick, add a *tiny* bit more cream. If it’s too thin, add a little more powdered sugar. You want it to be easily spreadable.

Frosting and Finishing Touches

  1. Now for the fun part! Frost those cooled cupcakes with your amazing peanut butter frosting. I like to use a piping bag for a fancy swirl, but spreading it on with a knife works great too!
  2. If you’re feeling extra, sprinkle some crushed Reese’s Pieces on top. Because, why not?!
  3. That’s it! You’ve made dark chocolate cupcakes with peanut butter frosting. Give yourself a pat on the back!

Tips for the Best Dark Chocolate Cupcakes with Peanut Butter Frosting

Want bakery-worthy dark chocolate cupcakes with peanut butter frosting? Of course, you do! Here are my secrets for cupcake perfection:

Ensuring Moist Cupcakes

Dry cupcakes are the WORST. Make sure you measure your flour correctly (spoon it into the measuring cup, don’t scoop!). And don’t overbake! A toothpick with a few moist crumbs is what you’re after. Oh, and that hot coffee? Don’t skip it. It really helps!

Achieving the Perfect Frosting Consistency

Frosting too thick? Too thin? Don’t stress! Add a *tiny* bit more heavy cream if it’s too thick, or a little extra powdered sugar if it’s too thin. Seriously, a teaspoon at a time makes a big difference! And make sure your butter is *softened*, not melted.

Storing Your Cupcakes

These are best enjoyed fresh, but leftovers (if there *are* any!) can be stored in an airtight container in the fridge for up to 3 days. Just let them come to room temperature before you devour them. Okay, maybe you don’t *have* to let them… I won’t judge!

Ingredient Notes and Substitutions

Sometimes, you’re missing an ingredient, or maybe you just want to switch things up! No problem! Here are a few notes and swaps for these dark chocolate cupcakes with peanut butter frosting:

Buttermilk Substitutions

No buttermilk? No sweat! Just add a teaspoon of white vinegar or lemon juice to a 1/2 cup of regular milk. Let it sit for a few minutes, and boom – you’ve got buttermilk! Works like a charm.

Peanut Butter Variations

I’m a creamy peanut butter kinda gal, but if you like some crunch, go for it! Crunchy peanut butter would be amazing in this frosting. Or, if you’re feeling adventurous, try almond butter or cashew butter. Just make sure it’s a smooth variety for the best frosting texture!

Frequently Asked Questions About Dark Chocolate Cupcakes with Peanut Butter Frosting

Got questions? I’ve got answers! Here are a few things folks often ask about these amazing dark chocolate cupcakes with peanut butter frosting:

Can I use regular cocoa powder instead of dark cocoa powder?

You *can*, but it won’t be quite the same! Dark cocoa powder gives these cupcakes that intense, rich chocolate flavor that’s just… well, dark! Regular cocoa powder will still work, but the taste will be milder. Just something to keep in mind!

How do I prevent my cupcakes from sinking in the middle?

Ugh, sunken cupcakes are so sad! Make sure your oven temperature is accurate. Also, don’t open the oven door too often while they’re baking. And most importantly, don’t overmix the batter! Overmixing develops too much gluten, which can cause them to sink.

Can I make these cupcakes ahead of time?

Yep! You can bake the cupcakes a day ahead, let them cool completely, and store them in an airtight container at room temperature. Just frost them right before serving for the best dark chocolate cupcakes with peanut butter frosting experience!

Can I freeze these dark chocolate cupcakes with peanut butter frosting?

You bet! Freeze the unfrosted cupcakes in an airtight container for up to 2 months. When you’re ready to enjoy them, thaw them completely at room temperature, then whip up the peanut butter frosting and frost away!

Perfect Pairings

How to Store Your Dark Chocolate Cupcakes with Peanut Butter Frosting

So, you’ve made these incredible dark chocolate cupcakes with peanut butter frosting, and somehow, you have leftovers? Wow, you’ve got more willpower than I do! Here’s how to keep them fresh:

Storage Instructions

For the best results, store these babies in an airtight container. If you’re eating them within a day or two, they’re fine at room temperature. But for longer storage, pop them in the fridge. Just remember to let them warm up a bit before you dig in – that frosting tastes *way* better when it’s not rock-solid!
