Ingredients You’ll Need

The beauty of this frosting lies in its simplicity—every ingredient truly counts. Each brings something special to the bowl, from creamy richness to just the right touch of sweetness. No fancy extras needed!

Creamy Peanut Butter: For the star flavor and a smooth, velvety base that whips up beautifully.
Unsalted Butter, Softened: Adds body and silkiness; make sure it’s at room temperature for easy blending.
Powdered Sugar: Sweetens and thickens, making the frosting light and spreadable without any graininess.
Heavy Cream: Loosens up the texture and makes the frosting ultra-fluffy—add a splash more if you want it softer.
Vanilla Extract: Accentuates the peanut butter’s nuttiness and adds that classic bakery aroma.
Pinch of Salt: Balances the sweetness and rounds out all the flavors—don’t skip it!

How to Make Peanut Butter Frosting

Step 1: Cream the Peanut Butter and Butter

Start by combining the creamy peanut butter with the softened unsalted butter in a large mixing bowl. Using a hand mixer or stand mixer, beat them together until the mixture is completely smooth and airy, with no visible streaks. This step ensures your Peanut Butter Frosting will be silky and perfectly blended from the very first bite.

Step 2: Add the Powdered Sugar

Gradually add two cups of powdered sugar, one cup at a time, while mixing at low speed. Pause to scrape down the sides of the bowl with a spatula to make sure everything gets incorporated. The mixture will look a bit thick and crumbly at first, but don’t worry—that’s exactly what you want at this stage!

Step 3: Flavor and Fluff

Add in the vanilla extract, a pinch of salt, and pour in 1/4 cup of heavy cream. Mix on medium-high speed for several minutes, watching as the frosting transforms into a light and fluffy cloud. If the frosting seems too thick or stiff, just add extra heavy cream, one tablespoon at a time, until your Peanut Butter Frosting is soft, pillowy, and ready for spreading or piping.

How to Serve Peanut Butter Frosting

Garnishes

Once your Peanut Butter Frosting is piled generously on cakes or cupcakes, sprinkle the tops with mini chocolate chips, chopped roasted peanuts, or even a drizzle of warm chocolate ganache for a show-stopping finish. These little touches add texture and make each bite extra special.

Side Dishes

Pair your frosted treats with a scoop of vanilla ice cream, a handful of fresh berries, or a tall glass of cold milk. The rich, nutty frosting plays so well with these sides, balancing the sweet and savory flavors and giving you that classic comfort-food vibe.

Creative Ways to Present

Pipe your Peanut Butter Frosting high onto cupcakes in tall, swirly peaks or spread it generously between layers of chocolate cake for a decadent, bakery-style look. You can also sandwich it between cookies, scoop a dollop onto brownies, or use it as a dip for pretzel sticks. Don’t be afraid to get playful—this frosting is a showstopper wherever you use it!

Make Ahead and Storage

Storing Leftovers

If you end up with extra Peanut Butter Frosting (lucky you!), scoop it into an airtight container and pop it in the refrigerator. It’ll stay delicious for up to five days. Be sure to bring it back to room temperature and give it a quick whip before using again to restore its creamy texture.

Freezing

This frosting freezes wonderfully, making it easy to get ahead on party prep. Transfer it to a freezer-safe container and freeze for up to three months. When you’re ready, thaw overnight in the fridge, then re-whip to bring back all that dreamy fluffiness.

Reheating

If your frosting seems a bit too firm after chilling, just let it sit at room temperature for 30 to 45 minutes. Beat it briefly with your mixer, adding a dash of cream if needed, and it’ll be just as light and spreadable as when you first made it. No melting or microwaving required!

FAQs

Can I use natural peanut butter for this frosting?

While natural peanut butter works, it’s usually much oilier and can make the frosting a bit runny or grainy. For best texture, stick to creamy, no-stir peanut butter to keep your Peanut Butter Frosting silky and smooth.

How can I make this frosting dairy-free?

Absolutely! Swap the butter with a good-quality dairy-free butter and use coconut cream in place of the heavy cream. The result will still be rich, fluffy, and just as delicious.

Is this frosting sturdy enough for piping decorative swirls?

Yes! This Peanut Butter Frosting is just the right consistency for gorgeous piping. If it feels too soft, chill it in the fridge for a few minutes or add a bit more powdered sugar to firm it up before decorating.

What cakes or cupcakes pair best with peanut butter frosting?

Chocolate, banana, and classic vanilla cakes or cupcakes are all delicious matches. Peanut Butter Frosting brings out the best in these flavors, creating a match made in dessert heaven.

How do I adjust the sweetness?

If you prefer your frosting less sweet, reduce the powdered sugar by up to half a cup. Taste as you go, and add a pinch more salt or an extra splash of vanilla to keep the flavors balanced.
