Ingredients You’ll Need

This recipe comes together with a handful of simple ingredients, each one playing a key role in the flavor, structure, and dreamy spreadability of Homemade Peanut Butter Frosting. Don’t skip or substitute—these pantry staples truly make the magic happen!

• Unsalted Butter, softened: Provides a rich, creamy base that lets the peanut flavor shine without being overly salty.
• Creamy Peanut Butter: The star of the show; choose your favorite brand for a smooth texture and robust peanut flavor.
• Powdered Sugar: Sweetens and thickens the frosting, creating that perfect fluffy consistency.
• Heavy Cream: Adds silkiness and makes it easy to achieve your ideal frosting texture—just add more as needed for spreading or piping.
• Vanilla Extract: A touch of pure vanilla rounds out the flavor and brings out the best in the peanut butter.
• Pinch of Salt: Enhances all the other flavors and prevents the frosting from becoming overly sweet.

How to Make Homemade Peanut Butter Frosting

Step 1: Cream Butter and Peanut Butter Together

Start by loading your softened unsalted butter and creamy peanut butter into a large mixing bowl. Using an electric mixer on medium speed, beat them together until the mixture is perfectly smooth, creamy, and completely blended. This base is the foundation for those classic peanut butter notes in every bite.

Step 2: Gradually Add the Powdered Sugar

With the mixer on low, slowly add the powdered sugar to your buttery peanut blend. Don’t rush this step; gradual addition ensures a flawless, lump-free result and keeps your kitchen free from sugar clouds. Beat until all the powdered sugar is fully incorporated and the frosting starts to look thick and a bit crumbly.

Step 3: Incorporate Cream, Vanilla, and Salt

Next, pour in the heavy cream, vanilla extract, and a generous pinch of salt. Now, increase your mixer speed to medium-high and watch your frosting transform—keep beating until it’s beautifully light, fluffy, and spreadable. If the frosting seems a bit stiff, simply add more cream a tablespoon at a time until it’s perfectly soft for spreading or piping.

Step 4: Adjust Consistency and Taste

If you want cloud-like swirls for cakes or silky rosettes for cupcakes, here’s your chance to fine-tune. Add a touch more cream if needed until you reach your preferred consistency, and have a quick taste to make sure the salt and sweetness are just right for your palette. That’s it! You’re ready to spread joy with your Homemade Peanut Butter Frosting.

Creative Ways to Present

For a show-stopping party platter, use Homemade Peanut Butter Frosting as cupcake filling or layer in trifles for a sweet surprise.

Make Ahead and Storage

Storing Leftovers

If you have any frosting left (lucky you!), simply store it in an airtight container in the refrigerator. It’ll stay fresh and creamy for up to 5 days—just let it come to room temperature and give it a quick stir before using.

Freezing

Homemade Peanut Butter Frosting is freezer-friendly! Spoon it into a tightly sealed freezer-safe container and freeze for up to 2 months. Thaw overnight in the refrigerator, then let it sit at room temperature and re-whip before spreading to restore its fluffy texture.

Reheating

If your frosting is a bit too thick after refrigeration, let it stand at room temperature for 20 to 30 minutes. If needed, beat it briefly with an electric mixer and add a teaspoon of heavy cream at a time until it’s perfectly spreadable again.

FAQs

Can I use natural peanut butter for this frosting?

Absolutely! Natural peanut butter provides a deeper, roasted peanut flavor. Just be sure to stir it very well before measuring, as the oil tends to separate and can change the frosting texture if not blended properly.

How can I make this frosting dairy-free?

Swap the butter for your favorite plant-based stick butter, and use coconut cream or a dairy-free cream alternative for the heavy cream. The frosting will still be rich, creamy, and packed with peanut butter goodness.

What should I do if my frosting is too runny?

If Homemade Peanut Butter Frosting turns out thinner than you’d like, add powdered sugar a tablespoon at a time and beat well after each addition until you achieve your desired thickness.

Is it possible to make this frosting less sweet?

If you prefer a less-sweet version, decrease the powdered sugar slightly, but keep in mind this will also affect the consistency. Taste as you go, and adjust the cream as needed to maintain spreadability.

Can I use crunchy peanut butter?

Definitely! Crunchy peanut butter adds tiny bits of peanut for extra texture. It won’t be as perfectly smooth, but it’s a fun twist, especially for those who love some nutty crunch in their Homemade Peanut Butter Frosting.

Final Thoughts

If you’ve ever wanted a frosting that feels just as comforting as your favorite childhood treat and yet bakery-worthy enough to impress, this Homemade Peanut Butter Frosting truly delivers. Give it a try on your next batch of cupcakes or brownies—it’s sure to be love at first bite!
