Ingredients in Peanut Butter Frosting
This recipe keeps things simple, but every ingredient works hard to deliver the dreamy texture and flavor we all crave. Let’s break it down:
Peanut Butter
The star of the show. Use creamy peanut butter for the silkiest texture, or go with crunchy if you’re into a little extra bite and texture. Natural peanut butter works too, just make sure it’s well-stirred.
Butter
Because frosting without butter is just… sad. Softened butter helps create that fluffy, spreadable consistency and adds a rich, creamy base that balances the peanut butter beautifully.
Powdered Sugar
For sweetness and structure. It thickens the frosting and gives it that classic bakery-style fluff. Plus, it blends in smoothly without any grittiness.
Milk or Cream
Just a splash to loosen things up and get the perfect silky texture. You can adjust the amount depending on whether you want a thicker or more pipeable consistency.
Vanilla Extract
A little vanilla adds warmth and rounds out the flavor. It’s subtle, but it makes a big difference.
(Note: the full ingredients list, including measurements, is provided in the recipe card directly below.)
Instructions
Let’s dive into the steps to whip up this dreamy frosting in no time:
Soften Your Butter
Start with room-temperature butter. It should be soft enough to press with your finger, but not melty. This helps it blend smoothly with the peanut butter and sugar.
Combine Peanut Butter and Butter
In a large mixing bowl, beat the peanut butter and butter together until creamy and well combined. This step sets the foundation for that irresistibly fluffy texture.
Add the Powdered Sugar
Gradually add the powdered sugar, mixing on low at first to avoid a sugar explosion (we’ve all done it). Increase to medium speed once it starts to come together.
Add Milk and Vanilla
Pour in a little milk or cream and the vanilla extract. Continue mixing until the frosting is smooth, fluffy, and light. If it’s too thick, add a touch more milk. If it’s too thin, add a bit more powdered sugar.
Whip It Good
Beat the frosting for another 1–2 minutes to make it extra fluffy. You want it soft, silky, and totally spreadable.
Serve and Enjoy
Use it right away to frost cupcakes, cakes, cookies—whatever your heart desires. Or store it for later (if you don’t eat it by the spoonful first).
How to Serve Peanut Butter Frosting
This frosting is incredibly versatile, so don’t hold back—get creative! Here are a few of my favorite ways to serve it:
Cupcakes
Spread or pipe it high on top of chocolate or banana cupcakes for the ultimate combo.
Layer Cakes
Use it between cake layers and on top for a rich, nutty twist on your favorite cake recipe.
Brownies
Spread it over cooled brownies and top with chopped peanuts or chocolate chips for a decadent upgrade.
Sandwich Cookies
Slather it between two cookies for an instant, creamy, sweet snack.
As a Dip
Yes, you heard that right. Serve it as a dip for apple slices, graham crackers, or pretzels for a sweet-and-salty treat.
Additional Tips
Use Creamy or Crunchy
Both work, depending on the texture you prefer. Creamy gives you that smooth bakery look, while crunchy adds fun texture.
Make it Ahead
You can make this frosting a day or two ahead and store it in the fridge. Let it come to room temp before using and give it a quick whip.
Store Properly
Store leftovers in an airtight container in the fridge for up to [time duration]. It also freezes well!
Flavor Swaps
Try adding a tablespoon of cocoa powder for a chocolate-peanut butter version or swirl in some honey for added sweetness.
Adjust the Sweetness
Taste as you go and adjust the powdered sugar to your preference. Some like it super sweet, others prefer a more savory vibe.
