This recipe was first featured with my Banana Cake with Peanut Butter Frosting. While that banana cake is delicious, I absolutely fell in love with the frosting. It’s light, fluffy, and not overly sweet. There is a very small amount of confectioners’ sugar added in addition to honey, but the peanut butter is the star. I think you will love this Fluffy Peanut Butter Frosting as much as I do!
This is a small batch frosting recipe, perfect for covering a 9-inch round cake or an 8-inch square cake. Of course, if you need more frosting you can double or triple the recipe. This fluffy peanut butter frosting can pair with a lot of flavors, especially chocolate and banana. The consistency is crazy fluffy, and once chilled, it has an almost mousse-like texture. I can literally eat it by the spoonful!
Low-sugar frosting, is it any good?
The answer is yes. While there is still sugar in this frosting recipe, there is significantly less than a regular buttercream recipe. The sweet flavor comes from the combination of honey and confectioners’ sugar. Depending on what brand of peanut butter you use, there may be some additional sugar in it as well.
So, how is this frosting made?
This recipe could not be simpler. The key here is to make sure that your butter is soft. Softened butter is essential to the fluffy consistency of this frosting.
In a mixing bowl fitted with the paddle attachment, mix together the smooth peanut butter, softened unsalted butter, salt, honey, and vanilla extract. With mixer on medium-high speed, whip the mixture until fluffy, about 3 minutes.
Add the sifted confectioners’ sugar and beat for an additional 2-3 minutes until fluffy, scraping as needed.
This Fluffy Peanut Butter Frosting is legitimacy good. I am pretty darn proud of this recipe. If you make it, let me know what you think in the comments. You can eat it by the spoonful, but it is also great on cake or brownies. Time to make a batch for yourself!
