Peanut Butter Frosting

Here’s the best peanut butter buttercream for cake and cupcakes! Peanut Butter Frosting is a sweet and salty nutty buttercream that is silky smooth and creamy. Use it to decorate your small batch desserts!

It’s been awhile since I posted a frosting recipe, but I’m back with Peanut Butter Frosting.

I first used this peanut butter buttercream to decorate my peanut butter birthday cake, but then someone asked if I had a recipe to go with my small chocolate cake.

This is what inspired me to post my recipe for peanut butter cake icing separately.

It’s a sweet and salty nutty buttercream that is creamy and silky smooth and a heavenly pairing for small batch chocolate cupcakes or banana cupcakes.

You can even use it as a filling for peanut butter sandwich cookies.

It’s also a bit sweeter than my peanut butter cream cheese frosting as it’s my small batch buttercream frosting with creamy peanut butter added.

And for my small batch dessert bakers out there, this small batch peanut butter frosting means you only make what you need without having to throw away the extra.

Ingredients For Peanut Butter Frosting

Here’s what you need to make your easy peanut butter frosting:

• Peanut butter: Made with your standard processed peanut butter. I’m not referring to natural peanut butter where you have to stir the oil before using.
• Butter: Provides creaminess and richness (hence the name buttercream)
• Powdered sugar: Both sweetens and thickens the frosting so you can easily spread or pipe it.
• Salt: Add a pinch of salt if using unsalted butter.
• Milk: Helps smooth out the frosting (especially if you’re spreading with a knife)
• Vanilla extract: Brings out the peanut butter flavor even more

How To Make Peanut Butter Frosting

Here’s how to make your peanut butter cake frosting:

1. Beat peanut butter, butter, powdered sugar, and salt together until smooth and creamy.
2. Add milk and vanilla. If it’s too thick, add more milk. If it’s too runny, add more powdered sugar.

Use immediately or store at room temperature for up to 1 day or refrigerate for up to 3 days.

What To Pair With Peanut Butter Buttercream Frosting

As much fun as it is to eat frosting with a spoon, chances are you need a cake recipe too. That’s why I wrote my 6 Inch Cake Recipes and Small Batch Cupcake Recipes guides.

Peanut butter buttercream frosting pairs perfectly with my small banana cake.
