Let me share a little confession…
For the longest time, I simply didn’t understand the widespread obsession with peanut butter. I’d often find my college roommate in the dim light of our kitchen, spoon in hand, scooping directly from a jar of peanut butter. While I didn’t actively dislike it, the idea of eating plain peanut butter straight was never appealing to me. It just wasn’t “my thing.”
Fast forward to today, and my perspective has completely shifted. While you still won’t catch me with a spoon in a jar, my love affair with peanut butter has blossomed into something magnificent – especially when it comes to baking. Now, I enthusiastically slather it on my morning toast, sandwich it between crisp crackers for a quick snack, and most importantly, I create this phenomenal frosting with it! My current obsession with peanut butter runs deep, making it a star ingredient in my kitchen.
Seriously, this isn’t just delicious; it’s dangerously delicious!
Imagine this luscious, creamy frosting crowning a rich chocolate cake, delicate vanilla cupcakes, or perfectly fudgy brownies. It’s a pairing that’s truly a match made in heaven, elevating every bite into a pure treat. If you’ve ever had my famous Snickers cake, then you’ve already experienced the magic of this very peanut butter buttercream. It’s simply outrageous – in the best possible way!
Now that we’ve set the stage, let’s dive into the specifics and uncover what makes this particular peanut butter frosting recipe stand out from the rest.
WHY THIS PEANUT BUTTER BUTTERCREAM IS YOUR NEW FAVORITE RECIPE
You might be thinking, “Does the internet really need another peanut butter frosting recipe?” And my answer is a resounding YES! Here’s precisely why this one deserves a permanent spot in your recipe collection:
- Significantly Less Sugar: Unlike many American buttercream recipes floating around the internet that often call for an overwhelming amount of powdered sugar, my recipe uses considerably less. In fact, most standard recipes use twice as much powdered sugar for the same amount of butter and peanut butter! This results in a frosting that is wonderfully sweet without being cloyingly so, allowing the true flavor of the peanut butter to shine through.
- Perfectly Pipeable & Stable: Despite its reduced sugar content, this frosting maintains a beautiful, sturdy consistency that is perfect for piping intricate designs, creating elegant swirls on cupcakes, or spreading smoothly over cakes. It holds its shape remarkably well, ensuring your desserts look as incredible as they taste.
- Light, Fluffy, and Velvety Smooth: The secret lies in the technique, which ensures maximum air incorporation. This results in a buttercream that is incredibly light, fluffy, and boasts a velvety-smooth texture, far from the heavy, greasy consistency often associated with less refined frostings. It truly melts in your mouth!
- Irresistibly Delicious: Even my husband and I, who aren’t typically huge fans of American buttercream due to its sweetness, found ourselves utterly smitten with this frosting. We couldn’t resist sneaking spoonfuls straight from the bowl! Its balanced flavor profile makes it universally appealing.
- Versatile for Any Occasion: This peanut butter buttercream is incredibly adaptable. It’s the ideal topping for a wide array of baked goods, from festive birthday cakes to everyday treats. Its classic appeal ensures it’s always a crowd-pleaser.
This recipe isn’t just about making frosting; it’s about creating a memorable dessert experience with a balanced, delectable peanut butter flavor and an unparalleled texture. Prepare to be amazed!
CHOOSING THE RIGHT PEANUT BUTTER FOR EXCEPTIONAL FROSTING
The type of peanut butter you use plays a crucial role in the texture and stability of your frosting. To achieve the absolute best results—a creamy, smooth, and perfectly pipeable buttercream—follow these guidelines:
- Opt for Conventional Peanut Butter: Always choose conventional peanut butter brands like Jif or Skippy over 100% natural peanut butters. Conventional brands contain stabilizers and emulsifiers that prevent oil separation and provide a thicker, more consistent texture. Natural peanut butters, while delicious for spreading, tend to separate their oils and have a thinner, runnier consistency, which can make your frosting difficult to work with and prone to greasiness.
- Go for Creamy, Not Chunky: For a truly silky-smooth frosting, creamy peanut butter is the only way to go. Chunky peanut butter will introduce small pieces of peanuts into your buttercream, disrupting its smooth texture and making it impossible to pipe cleanly. Save the chunky stuff for sandwiches and enjoy the refined texture that creamy peanut butter brings to your frosting.
MASTERING THE ART OF PEANUT BUTTER BUTTERCREAM: A STEP-BY-STEP GUIDE
Crafting this phenomenal peanut butter frosting is simpler than you might think, but there’s a key technique that sets it apart. Follow these steps for an irresistibly light and fluffy result:
- Whip Butter and Peanut Butter to Perfection: In a large mixing bowl (preferably using a stand mixer with a paddle attachment, or a hand mixer), combine your room temperature unsalted butter and creamy peanut butter. Begin beating on medium-high speed. This isn’t just about combining them; it’s about incorporating air. Continue beating for at least 2-3 minutes, or until the mixture transforms. It should become noticeably pale in color, significantly lighter in texture, and appear visibly increased in volume. It will transition from dense and yellow to airy and almost off-white. This step is absolutely critical for a light, non-greasy frosting. Don’t rush it! Regularly scrape down the sides and bottom of the bowl with a silicone spatula to ensure everything is evenly whipped.
- Gradually Incorporate Dry Ingredients: Once your butter and peanut butter mixture is light and fluffy, reduce the mixer speed to low. Gradually add the sifted powdered sugar in two additions. Sifting prevents lumps and ensures a smooth frosting. Add the salt and vanilla extract along with the second addition of sugar. Mix on low speed until the sugar is fully incorporated and no dry streaks remain.
- Achieve Ultimate Smoothness and Fluffiness: After the dry ingredients are incorporated, increase the mixer speed back to medium-high. Continue beating for another 1-2 minutes. This final whipping phase further aerates the frosting, making it wonderfully smooth, extra fluffy, and incredibly irresistible. Your frosting should be light, airy, and hold its peaks beautifully.
Expert Tip
The secret to a truly light, fluffy, and melt-in-your-mouth frosting lies in the initial whipping of the butter and peanut butter. Incorporating as much air as possible into this fat mixture *before* adding any sugar or flavorings is paramount. If the butter mixture isn’t whipped thoroughly enough, your frosting will end up dense, heavy, potentially greasy, and won’t hold its shape well for piping or decorating. Patience in this first step will reward you with a superior buttercream.
This versatile recipe yields a generous amount of frosting, perfect for various baking projects:
- Enough to generously frost 24 standard-sized cupcakes.
- The ideal quantity for a beautifully frosted two-layer 9-inch cake.
- Perfect for an impressive four-layer 7-inch cake.
STORING YOUR DELICIOUS PEANUT BUTTER FROSTING
Proper storage ensures your homemade peanut butter buttercream stays fresh and delicious for future use:
- Refrigeration: For immediate use within a week, transfer the frosting to an airtight container. Store it in the refrigerator for up to 1 week. When ready to use, bring it to room temperature and re-whip briefly until fluffy again.
MAKE-AHEAD AND FREEZING TIPS
This peanut butter frosting is excellent for preparing in advance, saving you time and effort when you’re ready to bake:
- Freezing: You can freeze this peanut butter frosting for longer storage. Place it in a freezer-safe, airtight container and freeze for up to 3 months.
- Thawing and Re-whipping: When you’re ready to use frozen frosting, simply transfer the container to the refrigerator and let it thaw overnight. Once thawed, bring the frosting to room temperature (this might take an hour or two on the counter). Then, transfer it to a mixing bowl and whip it again with a stand mixer or hand mixer until it regains its perfectly fluffy and smooth consistency. This re-whipping step is crucial to restore its original texture.

Print Recipe
Ingredients
- 2 sticks (226 g) unsalted butter (room temperature)
- 1 cup (260 g) creamy peanut butter (see Note 1 below for type)
- 2 cups (250 g) powdered sugar (sifted)
- 1 teaspoon pure vanilla extract
- ¼ teaspoon coarse kosher salt
Instructions
- In a large mixing bowl, using a paddle attachment for a stand mixer or a hand mixer, combine the room temperature unsalted butter and creamy peanut butter. Beat on medium-high speed for about 2 minutes, or until the mixture becomes notably pale in color, light in texture, and significantly fluffy. It should appear to have increased in volume. Halfway through, stop and thoroughly scrape down the sides and bottom of the bowl with a silicone spatula to ensure even whipping.
TIP: This initial whipping step is crucial. Incorporating as much air as possible into the butter and peanut butter mixture before adding sugar and other flavorings is the key to achieving a truly light, airy, and fluffy frosting. If this mixture is not whipped sufficiently, the resulting frosting may be heavy, somewhat greasy, and struggle to hold its shape for piping or spreading.
- Reduce the mixer speed to low. Add half of the sifted powdered sugar. Mix until the sugar is just incorporated into the butter and peanut butter mixture, being careful not to overmix at this stage.
- Now, add the remaining powdered sugar, pure vanilla extract, and coarse kosher salt. Continue mixing on low speed until all the dry ingredients are fully incorporated. Once combined, gradually increase the mixer speed to medium-high and continue beating for approximately 2 more minutes. This final whipping will ensure the frosting is wonderfully smooth, incredibly fluffy, and ready for decorating.

Tips & Notes
Note 1: Peanut Butter Choice: For the creamiest and smoothest frosting, it is highly recommended to use conventional creamy peanut butter (such as Jif or Skippy). Natural 100% peanut butters tend to separate oil and have a thinner, less stable consistency, which can negatively impact the frosting’s texture and pipeability.
Make-Ahead & Storage: This peanut butter frosting can be stored in an airtight container in the refrigerator for up to 1 week. For longer storage, you can freeze it in an airtight container for up to 3 months. To use frozen frosting, thaw it overnight in the refrigerator, then bring it to room temperature. Re-whip it in a mixer until it becomes light and fluffy again before using.

TROUBLESHOOTING COMMON FROSTING ISSUES
Even the most experienced bakers sometimes encounter hiccups. Here are solutions to common peanut butter buttercream challenges:
- Frosting is Too Stiff: If your frosting feels too thick or stiff, it might be due to too much powdered sugar or overly cold butter. Add milk or heavy cream, one teaspoon at a time, beating after each addition until you reach your desired consistency. Be cautious not to add too much liquid at once.
- Frosting is Too Thin or Runny: This usually means there isn’t enough powdered sugar or the butter was too warm to begin with. Add more sifted powdered sugar, one tablespoon at a time, beating until it thickens. If the butter was too warm, try refrigerating the entire bowl for 15-20 minutes, then re-whipping it.
- Frosting is Greasy: A greasy frosting often indicates that the butter was too warm, or it was over-mixed after the sugar was added, causing the fat to separate. If it’s only slightly greasy, chilling it for a bit and then re-whipping might help. If it’s very greasy, the emulsion may have broken, and it might be difficult to fully recover. Ensure your butter is at proper room temperature (cool to the touch but easily dented) from the start.
- Lumpy Frosting: This is almost always due to not sifting your powdered sugar or not scraping the bowl adequately. Sifting powdered sugar is a small extra step that makes a huge difference. If you have lumps, continue beating on medium speed and scrape the bowl frequently until smooth.
FREQUENTLY ASKED QUESTIONS ABOUT PEANUT BUTTER BUTTERCREAM
Here are answers to some common questions you might have when making this delightful frosting:
- Can I use natural peanut butter?
While you technically can, it’s not recommended for the best results. Natural peanut butters tend to separate more easily and have a thinner, oilier consistency, which can make the frosting less stable, difficult to pipe, and potentially greasy. Conventional creamy peanut butter (like Jif or Skippy) contains stabilizers that ensure a consistent, smooth texture perfect for buttercream.
- Is this frosting gluten-free?
Yes, typically all the ingredients used in this recipe (unsalted butter, creamy peanut butter, powdered sugar, vanilla extract, and salt) are naturally gluten-free. However, if you have severe gluten allergies or sensitivities, always double-check the labels of all your ingredients to ensure they are certified gluten-free, as some brands may have cross-contamination warnings.
- Can I make this frosting vegan?
You can! To make this frosting vegan, substitute the unsalted butter with a high-quality, plant-based vegan butter stick (ensure it’s suitable for baking/frosting). Most creamy peanut butters are already vegan, but always check the label. The rest of the ingredients are generally vegan-friendly.
- What is the ideal temperature for butter?
Your butter should be at “room temperature,” which means it should be cool to the touch but soft enough to leave an indentation when gently pressed. It should not be melted or overly soft, which can lead to a greasy frosting. This usually means taking it out of the fridge 30-60 minutes before you start.
- How long does it take to whip the butter and peanut butter until pale and fluffy?
This crucial initial step can take anywhere from 2 to 4 minutes, depending on the power of your mixer and the initial temperature of your ingredients. Look for visual cues: the mixture should lighten in color significantly and increase in volume, becoming visibly airy and fluffy. Don’t stop just when it’s combined!
