Peanut butter is one of my favorite flavors, so it’s about time I share my peanut butter buttercream recipe.
I love peanut butter so much, I add it to my oatmeal, and even my greek yogurt. Strange, I know! But I swear it’s delicious with honey. More importantly, I love baking with it!

This frosting is definitely on the sweet side, but the richness of the peanut butter helps balance out its flavor.
You could also add the same amount of peanut butter to a batch of my Swiss meringue frosting or try my Russian buttercream to create a less sweet peanut butter frosting.
Picking the Right Peanut Butter
One quick note around this recipe – it doesn’t work quite as well with natural peanut butter.
I find that because natural peanut butter can separate more easily, it can throw off the consistency of the buttercream. This can result in a messy, broken buttercream.

I usually use creamy peanut butter (like JIF or Skippy) and they incorporate really well into the frosting.
That being said, you can definitely experiment with your favorite peanut butter to see what works best for you!
Just be sure to use a creamy peanut butter, or else you won’t be able to pipe or smooth this frosting.

Paddle Attachment vs. Whisk Attachment
Now that we’ve covered troubleshooting, the last thing to discuss is our equipment.
Either a paddle or whisk attachment can be used to make this frosting with a stand mixer, or you can use a hand mixer.
I like to use my paddle attachment when making frosting for a cake to minimize the amount of air that is incorporated into the frosting. This makes silky smooth frosting, which is easier to smooth onto cakes.
I use my whisk attachment when making frosting for cupcakes, which I like to be light and fluffy!
I like to incorporate air into frosting for cupcakes because I usually pipe massive swirls onto each cupcake.
These are just my personal preferences, and you can use whatever attachment or mixer you have. They’ll all get the job done!

How Much Frosting Does This Recipe Make?
This recipe makes about 7 cups of frosting. If needed, this recipe can be halved or doubled. A double batch can be made in a 5 qt KitchenAid mixing bowl.
I usually make one batch to frost three dozen cupcakes with large swirls or to fill and frost a 7- or 8-inch layer cake.
Make this Peanut Butter Frosting in Advance
This peanut butter buttercream recipe can be made in advance. I highly recommend making it ahead of time if possible.
Not only does it give the frosting time to develop more flavor, it also makes the decoration of a cake or cupcakes less stressful and more fun.
This frosting keeps in the fridge for up to a month or in the freezer for 3 months if stored in an airtight container.
When you’re ready to use the chilled buttercream, remove it from the fridge a few hours in advance (or overnight) and allow it to come to room temperature.
Give it a good stir with a rubber spatula or an electric mixer to get rid of any air bubbles that may have formed. Once the buttercream is smooth again, it’s ready to use!

Tips for Making the Best Peanut Butter Buttercream Frosting:
- Make sure your butter is at room temperature before making your frosting.
- If your powdered sugar contains cornstarch (most brands in the US do), there’s no need to sift your powdered sugar.
- Use heavy cream or heavy whipping cream and not normal milk! You need a higher fat percentage for the frosting to have the right consistency.
- If you are making frosting for a cake, mix the buttercream on the lowest speed at the end of the process for a couple of minutes to get out any extra air that might have been incorporated during the mixing process.
- I usually make 1 batch of frosting to fill and frost a seven or eight-inch cake.
- This frosting is made with an American buttercream base, so it is on the sweet side. If you’re looking for a less sweet option, I recommend trying my peanut butter Swiss meringue buttercream recipe.

- Mix in 1 tsp vanilla extract and 1/2 tsp salt on a low speed until the ingredients are incorporated.
- Gradually mix in 7 cups of powdered sugar and 1/3 cup of heavy cream on a low speed. Scrape the sides and bottom of the bowl as needed with a rubber spatula.

Hi! I’m going to be making this frosting for a chocolate cake. I’m making it for a friend who requested flowers on the cake. Would I be able to pie flowers with this frosting and freeze them to add later? Or, should I just make a batch of American buttercream for the flowers??? Help!?

Hi Jerilyn,
For sure! This buttercream has a nice consistency and should work great for piping flowers. You can definitely freeze them, then add them to the cake later. Hope that helps, happy baking!
