This Peanut Butter Buttercream Recipe is one of my all-time FAVORITE frosting recipes. 

It makes the most wonderful peanut butter filling and frosting for chocolate cakes and cupcakes.  You will love the peanut butter flavor, the light and fluffy consistency, and how easily it pipes!

Not only does this peanut butter frosting taste fantastic, but the recipe is incredibly easy to throw together. Really, you're just minutes away from this deliciousness!!

Favorite Frostings for Chocolate Cakes

Chocolate cake pairs amazingly well with so many frostings, but this peanut butter buttercream is definitely in my top three.

For me, it's a three-way tie between Chocolate & Peanut butter (Peanut Butter and Chocolate Cake Mix), Chocolate and Mint (Mint Chocolate Chip Cake) and chocolate & coconut (Almond Joy Cake) I could never pick a favorite, but I highly recommend making each combo as often as possible (for comparison & research purposes of course!)

When your peanut butter cravings strike, this is the frosting that you. need!

Peanut Butter Frosting and Chocolate are the Perfect Combination

Okay, let's get back to the star of our post. There are countless reasons to love this recipe. This peanut butter frosting is perfectly peanut buttery, has a delightfully silky texture, and if you are a fan of the Viva Paper Towel Method of smoothing, it smooths exceptionally well.

There's no better match for peanut butter frosting than a delicious chocolate cake, is there? You have the sweet and salty flavors from the peanut butter buttercream, and the rich decadence of the chocolate cake. Perfection!

I absolutely love peanut butter buttercream swirled high onto cupcakes, sandwiched in between layers of rich chocolate cake, or injected into the centers of chocolate cupcakes to make them even more irresistible.

You can frost entire cakes with this recipe also, as we did in our AMAZING Peanut Butter Cake Recipe!


How to Inject buttercream filling into cupcakes

When I make cupcakes, I often fill the centers with a filling--sometime's it's the same as the swirled frosting on top, and other times I go with a different flavor.

I love this peanut butter buttercream frosting so much that I try to incorporate as much as possible!

To inject our peanut butter buttercream frosting into chocolate cupcakes as a filling, simply load a disposable piping bag with peanut butter frosting, snip away the tip, and insert right into the center of the unfrosted cupcake (about halfway down).

Give the piping bag a squeeze for 2-3 seconds, and you're done! If you don't have a practice cupcake to practice on, you can do a quick trial run on a plate just to get an idea of how much buttercream comes out of the bag in 2-3 seconds, and adjust to your liking! ;0)

How to Make peanut butter chocolate chip frosting

For a little variation (especially when using this as a filling for a chocolate layer cake) I love to stir in mini chocolate chips! Keep in mind that mini chips won't fit through small or closed star piping tips if you are planning to do any piping.

I will warn you that this frosting is HIGHLY addictive...and you may have to hide the bowl immediately after mixing up a batch.

The peanut butter frosting is a much lighter consistency than straight peanut butter, so you can easily get carried away with sampling. I know that I always do. Make it once and it'll be your go-to peanut butter buttercream frosting for life! YUM.


Easy and Delicious Peanut Butter Buttercream Frosting


Step away from the All Natural Peanut Butter! 

*One important thing to remember when choosing your Peanut Butter  for this recipe is that "natural" peanut butter doesn't work as well.

At least, the ones that we've experimented with over the years haven't worked as well. You can still use it if you must, the taste is still good, but the consistency isn't nearly as smooth.

I recommend peanut butter brands like JIF, Peter Pan, etc. (Oh, and buy creamy not crunchy- haha)

This amazing peanut butter buttercream frosting tastes amazing and is SO easy to make! We love it with chocolate cakes and cupcakesQ!

  • 2 sticks (226g) unsalted butter, slightly softened
  • 4 c. (460g) powdered sugar
  • ¼ cup (60g) milk plus 2 Tablespoon - use more if needed to reach the consistency you like
  • 2 teaspoons ( 8 grams ) vanilla extract
  • pinch of salt


  1. In the bowl of your mixer add the butter and mix on medium speed until the butter is softened and smooth. Add the peanut butter and mix until blended.
  2. Gradually add the powdered sugar alternately with the milk. Add vanilla. Mix on medium speed 4 to 5 minutes until smooth.
  3.  ***Peanut butter brands labeled "Natural" that I have tried do not work as well with this recipe because the consistency isn't as smooth & creamy. I've used Jif & Peter Pan (Creamy) with good results!

  1. Thank you for getting back to me. Good to know that I can use the heavy cream in lieu of the milk, this way I feel like I'm getting the most out of the ingredients. I will absolutely start with 2 tablespoons and go from there. I had just planned on using the peanut butter that I use for everything else (Peter Pan creamy), so good to know that will work too.

  2. Can you use salted instead of unsalted butter? Saw that you used a pinch of salt in your recipe so would this be okay and just skip adding in salt?

  3. I look forward to trying this peanut butter buttercream. How many cups of frosting does your recipe make?

  4. This recipe looks and sounds wonderful! I'm going to use it to replace my current PB Buttercream recipe because it has a higher peanut butter:10X sugar ratio. I currently use Wilton's PB buttercream recipe. Thank you for sharing! Your recipes are amazing!
