The Best Peanut Butter Frosting you will ever taste!

4.5 stars from 2 ratings of The Best Peanut Butter Frosting Ever!

Perfect Taste - Perfect Consistency! Light & Fluffy Peanut Butter Frosting Recipe

Ever wanted to make a peanut butter frosting that was not heavy and greasy? Do you have a peanut butter lover in your family? Perhaps one with a birthday coming up? Then this is the frosting for you!

Making a great peanut butter frosting can be tricky because it often comes out heavy and greasy. This recipes doesn't! This peanut butter frosting is light and fluffy and a great topper for cakes or cupcakes.

Try it out on chocolate cake or go for a peanut butter explosion with a peanut butter cake.

This recipe was made up by me in effort to make a fluffy peanut butter flavored frosting for a cake at a wedding.

I made several cakes as trials, and the ones with this frosting got 100% thumbs up.

You should try this if you are looking for a great consistency and great tasting frosting that is Peanut Butter. Many compliments have come my way on this frosting.

You have to plan a little ahead to get my secret ingredient, but it makes all the difference.


  • 1 2 lb bag of Confectionery Sugar (sifted again by you)
  • 2 sticks of real butter (salted) - room temp if possible
  • 1 cup of heavy cream
  • 1 jar of PB2 - 6.5oz (this is the secret ingredient !!!) - SEE BELOW FOR MORE INFO ON PB2
  • 1 bag of Reeces Peanut Butter Chips (*optional)


  1. 1. Start by creaming the butter until creamy. It's best if it's soft or room temp to start with.
  2. 2. Add one jar of PB2 and mix until even and all one color. (You may need to scrape down sides of bowl if using stand mixer.)
  3. 3. Add the confectionery sugar and heavy cream alternating some of each to keep consistency mixable.
  4. 4. Once all is in, turn up the mixer and whip it up. It should come out nice and fluffy.
  5. Give it a little taste - you won't be disappointed.
  6. Frost your cake (is great on peanut butter cake, white cake, and chocolate cake)
  7. *Optional - If making a layered cake, add a ton of Reeces Peanut Butter Chips to the frosting that is between the layers. It makes for an great taste and nice surprise. YUMMY!
  8. TIPS:
  9. - DO sift confectionery sugar to keep frosting fluffy - if you don't sift, it will weight down the frosting and leave some lumps.
  10. - DO use PB2 if at all possible. It makes a world of difference. Can add one cup of regular peanut butter if you choose, but it makes the frosting much thicker and a little greasy and it appears like other peanut butter frostings - but doable.
  11. - You CAN add a little more heavy cream if needed to thin it out if needed, or less if too thin, but usually one cup does well.
  12. - I suggest a good electric mixer and a big bowl. I use a Kitchen Aide stand mixer which works great.

The Secret Ingredient: PB2

This is the secret ingredient to make the frosting fluffy!

PB2 is the key to making your frosting fluffy and not greasy. It is a peanut butter product that 100% natural, and 85% less fat than regular peanut butter. It is gluten free and contains no preservatives or sweeteners or artificial flavors. The peanuts have had their oils extracted, thus leaving this powdered peanut product. PB2 has three ingredients: roasted peanuts, sugar and salt. It can be hydrated with a small amount of water, and used as a healthy alternative to regular peanut butter (it tastes exactly the same). PB2 is made by only one manufacturer at this time, Bell Plantation.

Read the nutritional facts for PB2.

I use this in my frosting to eliminate the greasy, heavy consistency that peanut butter usually gives a recipe. This frosting has proven to be super fluffy, creamy, and much lighter than other peanut butter frostings - thanks to the PB2.

Where Can I Get PB2?

PB2 is only really available online so you will have to plan ahead or just keep some PB2 on the shelf. You can buy it here:

The Peanut Butter Inspiration

A Peanut Butter Grooms Cake

The reason I focused my energies on developing a great recipe for peanut butter frosting was that I wanted to make a peanut butter grooms cake for my brother's wedding. All his life he was been a huge peanut butter fanatic. He loves everything peanut butter, but he really was not a really a chocolate lover. He'll eat a little chocolate but only if combined with a ton of PB!

For his over-the-top Pirate theme wedding, I made this Peanut Butter Delight Cake. It was an over-the-top peanut butter explosion. It was a two layer peanut butter cake with this fluffy peanut butter frosting. Between the layers were peanut butter chips in the frosting. On top is peanut butter crumbles (mashed Nutter Butters cookies), and a treasure chest filled with gold (yellow Reece's Pieces). Yep, he loves peanut butter.

If you love Peanut Butter - especially if you love Peanut Butter without a bunch of Chocolate ... This is your Cake !!!

What cake does this frosting work well with? - Nearly any cake, but here are my suggestions.

These are the cakes that I have tried to add my peanut butter touch to - and they have come out great!

Getting the Perfect Consistency (Do I just whip the frosting?)

How do I keep my Peanut Butter frosting light and fluffy?

People wonder how to make a good peanut butter frosting - one that is light, fluffy, non-greasy, not heavy, not oily, not too thick - a peanut butter with the perfect consistency. This frosting is not TOO peanut buttery for the typical taster, but the perfect peanut buttery for the peanut butter lover.

My recipe is all of that. You can't mess this up! It's easy to spread and great to taste.

If you whip ANY frosting in electric mixer, it will be fluffy - at least temporarily. This is true of ALL frostings, but beware: a frosting that relies on whipping alone for fluffiness, will not remain fluffy for long. Whipping a frosting simply puts air into the frosting making it appear lighter, but within an hour or so (sometimes a bit longer) the fluff floats away leaving you with a sagging look and a frosting that has returned to thicker consistency. It also can slightly alter any decorating techniques that you might have used.

THIS recipe uses the ingredients to make it fluffy not only whipping, so it KEEPS the frosting light and fluffy.

Many peanut butter recipes will tell you to whip for 3 minutes at end of directions which is is to counteract the heavy oily peanut butter, but this approach will be temporary. Using this recipe you'll get fluffy frosting from the get go, and you can whip this even more if you like, but it's not needed. This frosting will stay fluffy.

I like my peanut butter straight up, but if you want a hint of chocolate in your frosting, try this PB2 with chocolate!


What should I use this frosting for?

  • Perfect frosting for Chocolate Cake
  • Awesome frosting for Peanut Butter Cake
  • Perfect for topping Cheesecake
  • Great spread on brownies
  • Perfect for on White Cake
  • Cupcakes (with a peanut butter cup dropped in the batter of each one after in the paper liners but before baking)
  • Heck - just make a batch and eat it plain - you know you want to ! hehe

I did not buy the PB2 and do not have time now ...

What do I do ?

You can substitute peanut butter for the PB2. If you do, I would suggest using a lighter version (such as Jiffy or Peter Pan vs. Generic etc...) and be sure it is a smooth version (not chunky).

I would also add a little extra heavy cream, and be sure to whip it as much as possible to make it light and fluffy. Do be aware though, that it will likely settle some so do not make it too early, and do not refrigerate - both will thicken and drop the frosting. (the PB2 version will stay light and fluffy no matter what !)

I strongly suggest getting the PB2 if you have time though ! It is WELL WORTH IT ! - but as for taste - the above will also taste good.

If you DO try my recipe - Please come back here and drop a note, so other readers may get reviews besides just from me ! Give YOUR review of THIS recipe ! (all other comments about the page, please put in guestbook above)

      @anonymous: I never actually measured it, but I use a kitchen aide mixer and the bowl is as full as you can get it and still use it. There is 2 full lbs of confection sugar in it, I think 8 cups is safe to say- maybe more ... but again I did not actually measure ... sorry. I will try to measure the next time I make it - or if you make it and measure, let me know so others can have this info. I am sorry - that would have been good info ...

      @TravelingRae: I did try many and never got the result I was looking for...

      Later, I came across PB2 and just did some thinking - figuring if it had no oil, and was a powder, that it should mix up way fluffy - and it DID !

      It really is awesome - if you love fluffy peanut butter frosting - this is it - I hope you get to try it sometime !
