A silky smooth but perfectly pipeable peanut butter frosting that’s the perfect complement to any cake or cupcake. Also great for just eating by the spoonful!
Maybe you guys haven’t noticed, but I’ve been working on bulking up my “Frostings” section on the blog.
In the past, I would share cake or cupcake recipes and tag on my preferred complementary frosting, but I’m a big believer in choices. Maybe you’d rather frost your funfetti cake with chocolate frosting (or even peanut butter frosting) instead of buttercream, right? Well I wanted to have a good variety of options for you to choose from.
So far I’ve shared my favorites of the following:
- Cream cheese frosting (<—- possibly my favorite frosting of all-time)
- Chocolate frosting
- Vanilla buttercream frosting
And today I’m adding peanut butter frosting to the list.
This recipe is super easy to make, and on Monday I’ll be sharing a very complementary and very dark chocolate cupcake recipe with you, but of course you can put it on whatever you want. You can even just eat it by the spoonful, I know I did.
And yet it remains a mystery to me why my cardio sessions aren’t paying off 😭
Anyway, Peanut Butter Frosting requires just 6 ingredients to make. It’s smooth, creamy, and is great for piping on top of cupcakes or decorating a cake.
Tips for Making Peanut Butter Frosting
- While chunky or creamy peanut butter can work in this peanut butter frosting recipe, I don’t recommend using chunky unless you don’t intend to pipe the frosting. The little peanut pieces will clog up your frosting tips in a second.
- I don’t recommend using natural peanut butter (the kind that separates, you know the one that you usually need to stir before using). I haven’t tried it myself but I’m pretty certain that it wouldn’t work too nicely work with this recipe (it would be too oily).
- This peanut butter frosting pipes very nicely as written. However, for a stiffer frosting, you can add an additional ½-1 cup (65-125g) of powdered sugar.
How Many Cupcakes/How Much Cake Will this Peanut Butter Frosting Cover?
- If you’re generously frosting your cupcakes (as seen in my cupcake photo below), then this frosting will handily cover 12-15 cupcakes. If you’re being a bit more modest, it will cover 24 (I covered 24 cupcakes with peanut butter frosting rosettes using the 1M tip).
- This frosting will also cover a 9×13 sheet cake or a round 2-layer 8″ or 9″ cake. Now I’m just thinking about how I want to make a cake with this frosting and then cover it with ganache… Yum!
Enjoy!
Oh, and do you have any requests for other frosting recipes you’d like to see? I’m currently working on caramel but would love any suggestions that you have!

My favorite frosting ever! I have my ingredients out because I’m making a cake in the morning!! I can’t wait!
Emily @ Sugar Spun Run
Thanks for the review, Abby! Enjoy that frosting 😋
Mimi
The flavor was amazing however it was not spreadable
what did I do wrong or what should I change?
Thanks!
Sam
Hi Mimi! Was it just too thick? A splash of cream or milk would help with this, add a Tablespoon at a time and stir well after each Tablespoon until you have a smooth, spreadable consistency. I hope this helps! 🙂
Adina
I just made and had to add a LOT more cream. I made with a cup less sugar and almost a full cup of heavy whipping cream. Mine topped a cheesecake
Tracy
Thank you so much!!! In a panic while making my grandson birthday cake, tried an Italian peanutbutter butter cream and it was a disaster!!! Jumped to this made it quick and it’s terrific!!!! Again, thank you for saving the day!!!
Lele
Bro this recipe is perfect
I’m an amateur baker to say the least and this took almost no time at all. Even issuing a manual hand mixer, it came out fluffy and tastes awesome
I’m so excited. Def will recommend to people

This. Is. Amazing. The perfect remedy for a boring chocolate cake – from a BOX *gasp* – because you have cake mix you need to use up. The texture is perfect! I’ve made this for cupcakes, brownies, basic chocolate cake, and even just because… I wanted to eat it by itself. To me, cake is really just a holder for frosting, because I don’t love cake. This frosting is truly the CENTERPIECE, screw the cake! 😉
Jessica
Yes!

This is the best peanut butter frosting I have ever had! It is my new go-to peanut butter frosting, creamy, smooth, easy to spread and simply light and delicious.
Emily @ Sugar Spun Run
We’re so happy you love it, Karen! Thanks for your review ❤️
Nicole
I only had natural peanut butter so I tried it with some PB2 (a mix of ground peanuts, salt and sugar) hoping that would absorb any of the excess oiliness, and it worked great. Thanks for the delicious recipe!!
Emily @ Sugar Spun Run
Thanks for letting us know how that worked for you, Nicole! ❤️
Stef
Hands down the best, most velvety smooth, not overly sweet pb frosting ever!!! It’s perfect. It held its shape and everyone loved it. If you start altering the recipe don’t even rate it because it perfect as written. Follow it and you cannot go wrong. 10/10

Absolutely wonderful peanut butter frosting.i used it for cup cakes for my grandsons wedding. I did a line of chocolate frosting (made from scratch) and a line of the peanut butter frosting on golden cupcakes with a piping bag. They were so pretty. Every one loved them. I added chopped peanuts to the tops so people could see there was peanuts in the cupcakes incase they had an allergy.
Emily @ Sugar Spun Run
They sound divine, Julia! We’re so happy this was a hit for you 😊

Love this recipe. My dad is super picky peanut butter frostings but this one was his absolute favorite. Super easy to make and tastes delicious!
