Whether you’re frosting a birthday cake or sneakily sampling it with a spoon, this irresistible topping promises to add a decadent finish to any dessert and entice everyone back for seconds.

Ingredients You’ll Need

Each ingredient in this Creamy Peanut Butter Frosting recipe does more than its fair share, coming together to create the ultimate spreadable topping. You’ll likely have most of these kitchen staples on hand, and you’ll be amazed how each component—simple as it seems—contributes essential flavor, texture, or structure.

  • Creamy peanut butter: The star of the show, providing depth, nuttiness, and that classic, luxurious peanut flavor.
  • Unsalted butter (softened): Adds fluffiness, creaminess, and a subtle richness that supports the peanut butter.
  • Powdered sugar: Lends sweetness and a smooth, satiny finish—don’t substitute with granulated sugar, or you’ll lose that dreamy texture.
  • Heavy cream: The secret to truly creamy, silken frosting; it lightens up the mixture and makes it fabulously spreadable.
  • Vanilla extract: Just a touch rounds out the flavors and underscores the sweetness.
  • Pinch of salt: A little bit lifts the sweet and nutty notes, creating perfect balance in every bite.

How to Make Creamy Peanut Butter Frosting

Step 1: Beat the Peanut Butter and Butter

In a large mixing bowl, combine the creamy peanut butter and the softened unsalted butter. Using a hand mixer or stand mixer, beat them together on medium speed until the mixture is completely smooth and fluffy—this usually takes about 2 minutes. This step is crucial for a lush, uniform base, so don’t be afraid to let the mixer run a little longer for extra creaminess.

Step 2: Gradually Add the Powdered Sugar

With your mixer on low, add the powdered sugar one cup at a time. Beat thoroughly after each addition to avoid any lumps and to help the sugar fully dissolve into the butter-peanut butter blend. The frosting will start to look thick but don’t worry: the magic will happen in the next step.

Step 3: Add Vanilla Extract and Salt

Pour in the vanilla extract and sprinkle in a pinch of salt. These seem like small additions, but they make a big impact on the final taste, enhancing both the sweetness and the complexity of your Creamy Peanut Butter Frosting.

Step 4: Pour in Heavy Cream for Perfect Texture

Slowly drizzle the heavy cream into your mixture while continuing to beat everything together. This is the step where the frosting turns irresistibly silky. Keep beating until the frosting is smooth and spreadable. If it’s still too thick, add more cream 1 tablespoon at a time, mixing well after each addition, until your desired consistency is reached.

Garnishes

For a show-stopping finish, sprinkle your freshly frosted cake or cupcakes with roasted peanuts, mini chocolate chips, or even a pinch of flaky sea salt. The garnish adds crunch, color, and a hint of sophistication to your already delicious Creamy Peanut Butter Frosting—plus, it’s a fun way to customize for any occasion.

Side Dishes

This dreamy frosting pairs beautifully with all sorts of cakes, especially chocolate and banana varieties. But don’t stop there: try it on brownies, sandwiched between cookies, or swirled onto cinnamon rolls for a playful twist. A tall glass of ice-cold milk or a coffee-based drink on the side makes the peanut butter flavors shine even more.

Creative Ways to Present

Bake a batch of cupcakes and swirl your Creamy Peanut Butter Frosting high with a piping bag, or go rustic and artful with swoops for a homemade look. For parties, try using it as a dip for pretzel rods or apple slices. You can even use it to fill layer cakes or as a decadent filling in sandwich cookies—the options are nearly endless!

Make Ahead and Storage

Storing Leftovers

If you have extra Creamy Peanut Butter Frosting, simply transfer it to an airtight container and refrigerate. It will keep for up to one week. Before using, let it sit at room temperature for 20-30 minutes, and give it a quick stir or re-whip to fluff it back up.

Freezing

Need to prepare ahead? No problem! Scoop your frosting into a freezer-safe container, seal tightly, and freeze for up to 2 months. Thaw overnight in the fridge and then bring to room temperature before using. A quick whip with your mixer will restore its soft, spreadable texture.

Reheating

If the frosting has become a bit too firm, especially after refrigeration or freezing, just let it warm up at room temp. For an extra-silky finish, beat it for a minute or two with an electric mixer, adding a touch more cream if needed. Avoid microwaving, as it can separate or melt the fats.

FAQs

Can I use natural peanut butter for this Creamy Peanut Butter Frosting?

Natural peanut butter, while delicious, tends to separate and has more oil, which can affect texture. For best, most consistent results, stick with a creamy, no-stir variety—you’ll get a smoother, more reliable frosting every time.

How can I make the frosting less sweet?

If you prefer a less sweet version, try reducing the powdered sugar slightly, but do keep in mind it helps with structure. You might also add a couple extra pinches of salt or opt for a bit more peanut butter for a bolder, more savory edge.

Is this frosting suitable for piping and decorating?

Absolutely! Creamy Peanut Butter Frosting is sturdy yet soft enough for most decorating needs. For sharper shapes or designs, use a little less cream to make it stiffer. It holds up beautifully on cupcakes, cakes, or sandwich cookies.

Can I make this frosting dairy-free?

To make it dairy-free, substitute plant-based butter and coconut cream (the thick part from a can) for the dairy ingredients. The end result is still rich, smooth, and packed with peanut butter flavor, though texture may vary slightly.

What can I do if my frosting turns out too runny?

If the frosting gets too thin, add a bit more powdered sugar until desired thickness returns. Be sure to add sugar gradually, beating well after each addition for a lusciously creamy finish.

Final Thoughts

If you’re ready to fall in love with your new go-to frosting, don’t wait another second to whip up this Creamy Peanut Butter Frosting. Each batch brings the perfect blend of nutty, creamy, and sweet flavors—perfect for cakes, cupcakes, and anytime cravings. Grab your mixer and enjoy the simple joy of homemade decadence!
