I can’t believe I’ve never shared my peanut butter cupcake recipe with you before…!

I mean, for a gal who frequently blogs with a jar of peanut butter and spoon at her desk (so true), it’s quite surprising that I don’t have a darn cupcake flavored by my beloved peanut butter featured on my website.  Well, today I’m changing that and am bringing you the peanutbutteriest* cupcake recipe you’ll ever find.

*Peanutbutteriest is a word today.

I slathered today’s cupcakes with a deep, dark chocolate frosting that will give anything “decadent” you’ve ever tasted a run for its money.  We’re talking pure decadence.  You’ll be screaming for a tall glass of milk after your first bite.

I’ve tasted a lot of peanut butter cupcakes and have tried my hand at several recipes.  I’ve found the peanut butter cupcakes can either be (1) way too dry, (2) much too dense, (3) lacking peanut butter flavor, or (4) all of the above.  I was often stuck in a peanut butter cupcake conundrum before this recipe happened. It’s truly a difficult cupcake flavor to master!

I know many of you (myself included!) despise the word “moist” but I must repeat myself over and over again here. These peanut butter cupcakes are SO moist and they’re extremely tender as well. Not spongey or falling apart though.  My secret little weapon is all the dark brown sugar I use to sweeten them up.   I’ve told you this a lot, but I just love baking with dark brown sugar. It delivers an unbeatable soft and moist texture and does NOT disappoint in today’s recipe.

The best part about these cupcakes?  They actually taste like peanut butter. I maxed out the batter with 2/3 cup of creamy peanut butter for only 12 cupcakes. They aren’t vanilla cupcakes with peanut butter; they are pure peanut butter in cupcake form. Told ya… the peanutbutteriest ever.

What I love most about this recipe besides the taste and texture is how easy they are to make.  Just a few simple, standard ingredients mixed together and you’re finished.  Your usual suspects are present in the recipe: flour, baking powder, salt, butter, brown sugar, vanilla, milk, and oh… peanut butter.  I always use Jif Creamy for this recipe. I don’t suggest an oily, runny peanut butter here – unless the natural peanut butter you have is quite thick.

The cupcakes only take about 23-25 minutes to bake.  I’ve even used this recipe to make a peanut butter cake before – simply pour the batter into a 8-inch or 9-inch square or round baking pan and bake for about 35 minutes.   Easy!

While the cupcakes bake in the oven, prepare the creamy, dreamy, dark-as-midnight chocolate frosting.  Don’t like dark chocolate? I got ya covered.  Try my Milk Chocolate Frosting instead.

{yes, everything I own is pink.}

The secret to my dark chocolate frosting? Well, there isn’t one.  It’s simply butter, powdered sugar, heavy cream, vanilla, and unsweetened cocoa powder.  I use less powdered sugar for this frosting and more cocoa powder than my milk chocolate frosting.  It’s not rocket science!  Just frosting. :)

I prefer heavy cream in the frosting – it lends the creamiest texture.  Heavy cream is what makes my peanut butter frosting so darn thick, fluffy, and smooth. I almost always use it for any buttercream/frosting I make.  I highly recommend it over milk or half-and-half.

For the cocoa powder, I like to use Hershey’s Special Dark here, but any unsweetened cocoa powder will be just fine.

Keep in mind two very crucial notes for the frosting: (1) make sure your butter is softened and not melted in the slightest.  I simply took my butter stick out of the refrigerator and let it sit on the counter for 45 minutes as I baked and cooled the cupcakes.  (2) Beat the butter by itself for a minute or two before adding anything else. It creates a solid creamy base this way, rather than adding the other ingredients with the butter in it’s solid state.

Mmm I could eat the dark chocolate frosting with a spoon and be set for life.  I’d also need my running shoes too, but that’s beside the point.

Is there anything better than a peanut butter cupcake topped with chocolate frosting? Yes, there is. A peanut butter cupcake topped with chocolate frosting topped with a mini peanut butter cup.  I mean, one can never have enough chocolate and peanut butter, right?!

Surely you may adorn your cupcake with any accessory of choice, but I flippin’ adore these mini peanut butter cups!  I couldn’t help myself.

These cupcakes are everything you want and more in a peanut butter cupcake: moist, tender, easy-to-make, and loaded with peanut butter flavor.  Kevin describes them as “very good” which is a HUGE step up from his usual “it’s good.”  They get a very good – huge pat on the back for Sally!! 😉

There’s just something about cupcakes I love.  Perhaps it’s the portion control… nope, it’s not that.  Perhaps it’s the amount of frosting I can get away with piling on top? Getting closer.  Oh yes… it’s because I don’t need a fork or plate to dig right in. Cupcakes to the face.

I’m still looking to hire a dish-washing fairy, by the way.

Peanut Butter Cupcakes with Dark Chocolate Frosting

Yield: 12 cupcakes

Print Recipe

These are absolutely the best peanut butter cupcakes I've ever had. Top them with dark chocolate frosting for one out-of-this-world treat!

Ingredients:

  • 1 and 1/4 cup all-purpose flour
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 2/3 cup creamy peanut butter
  • 8 Tablespoons (1 stick) unsalted butter, softened to room temperature
  • 3/4 cup packed dark brown sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/4 cup milk*

Dark Chocolate Frosting

  • 2 and 3/4 cup powdered sugar
  • 2/3 cup unsweetened cocoa powder, I used Hershey's Special Dark
  • 6 Tablespoons unsalted butter, softened to room temperature
  • 6 Tablespoons heavy cream
  • 1 teaspoon vanilla extract

Directions:

Preheat oven to 350F degrees. Line 12-cup muffin pan with liners. Set aside.

For the cupcakes: Mix together the flour, baking powder, and salt. Set aside. With a handheld or stand mixer, cream together the peanut butter, butter, and brown sugar until light and fluffy; about 2 minutes on medium speed. Beat in the eggs, one at a time, then add in vanilla. Scrape down the sides as needed. Slowly beat in the flour mixture alternately with the milk, mixing until just combined. Do not overmix. Batter will be thick.

Divide batter evenly between 12 cupcake tins. Bake for 23-25 minutes or until toothpick inserted in the middle of a cupcake comes out clean. Allow cupcakes to cool before frosting.

For the frosting: Sift together the powdered sugar and cocoa powder to assure there are no lumps. Set aside.

With a handheld of stand mixer, beat the butter at medium speed until fluffy - about 2 minutes. Gradually add the sifted sugar/cocoa powder alternately with the heavy cream and vanilla. Beat on low speed after each addition. Add more powdered sugar if frosting is too dark. Add a pinch of salt if frosting is too sweet. Frost cooled cupcakes as desired. I used Wilton tip #12 to pipe my frosting.

Cupcakes stay fresh at room temperature in an airtight container for up to 4 days. Store covered in the refrigerator is desired for up to 1 week.

Additional Notes:

*Try my Milk Chocolate Frosting if you're not a fan of dark chocolate.

*I like to use buttermilk in the cupcakes - makes them extra moist!

    hey! I was just wondering if you use the same amount of buttermilk as you do milk?

    These have a great taste, but do not rise and they pull away from the wrapper. I tried them twice thinking that my baking powder might not be as fresh as it needed to be. I had the same results both times. Is this “normal” for these cupcakes or am I doing something wrong?

    I was very excited to make these cupcakes for my boyfriend as he’s all about the peanut butter.  Unfortunately, they turned out very dry.  I will try them again with more milk and butter as the peanut butter flavour was great, despite the crumbling.
