Essential Peanut Butter Frosting Ingredients
Crafting the perfect peanut butter frosting starts with understanding the role of each ingredient. Below, I’ve detailed the whole 5 ingredients you’ll need. Each one plays a crucial part in achieving that desired smooth, creamy, and flavorful result. Don’t forget to scroll to the comprehensive recipe card at the bottom of the post for the full ingredients list with exact measurements and detailed recipe instructions.
- Butter: For best results, I highly recommend using unsalted butter. This gives you full control over the saltiness of your frosting. However, if you enjoy a delightful sweet-salty contrast, salted butter can also work beautifully. Ensure your butter is at room temperature for optimal creaming; it should be soft enough to leave an indent when pressed, but still cool to the touch. This helps achieve a lump-free, aerated base for your frosting.
- Peanut Butter: The star of the show! You’ll need a creamy, shelf-stable peanut butter for this recipe. Brands like Jif or Skippy are perfect as they are formulated to be “no-stir,” meaning the oils won’t separate. This is critical for achieving a stable, smooth frosting.
- Powdered Sugar: Also known as confectioner’s sugar or icing sugar, powdered sugar is essential for both sweetness and texture. Its fine consistency dissolves easily, preventing graininess and contributing to the frosting’s silky smooth finish. Sifting the powdered sugar before adding it can help prevent lumps, though with an electric mixer, it’s often not strictly necessary.
- Vanilla Extract: A touch of vanilla extract rounds out the flavors, adding depth and warmth that beautifully complements the rich peanut butter. For the best, most authentic taste, always opt for real vanilla extract over imitation.
- Milk: Milk is used to adjust the consistency of the frosting, helping it become perfectly spreadable or pipeable. Both whole milk and 2% milk will work well in this recipe. Start with the recommended amount and add more gradually, a tablespoon at a time, until you reach your desired thickness. For an even richer frosting, heavy cream can also be used.
What Type of Peanut Butter is Best for Frosting?
This is a common and critical question when making peanut butter frosting. To achieve the best consistency and prevent separation, it’s absolutely essential to use a no-stir, creamy peanut butter, such as popular brands like Jif or Skippy. While homemade peanut butter and natural peanut butter (the kind that requires stirring the oil back in) are delicious for eating straight from the jar, they are not suitable for making frosting. The natural oils in these types of peanut butter tend to separate from the other ingredients, leading to an oily, curdled, or unstable frosting that won’t hold its shape or texture.
How to Make Perfect Peanut Butter Frosting
Making homemade buttercream frosting is a quick and satisfying process, and this peanut butter version is no exception. Follow these simple steps to create a smooth, creamy, and irresistible frosting:
- Step 1: Whip the Butter and Peanut Butter. In a large mixing bowl, combine your softened room-temperature butter and creamy peanut butter. Using an electric mixer (either a stand mixer with a paddle attachment or a hand mixer), beat them together on medium speed until the mixture is completely smooth, light, and fluffy. This creaming process incorporates air, which is key to a light and airy frosting texture. Make sure there are no lumps of butter remaining.
- Step 2: Combine Remaining Ingredients and Beat to Perfection. Once the butter and peanut butter are well combined, gradually add the powdered sugar, vanilla extract, and milk to the bowl. Start on low speed to avoid a cloud of powdered sugar, then increase to medium-high. Continue to beat the frosting for several minutes until it achieves a perfectly spreadable and pipeable consistency, free from any lumps. Scrape down the sides of the bowl occasionally to ensure all ingredients are thoroughly incorporated. The longer you beat it (without overbeating, see tips below), the lighter and fluffier your frosting will become.
Expert Tips for the Best Peanut Butter Frosting
Even though this recipe is incredibly easy, a few expert tips can ensure your peanut butter buttercream turns out absolutely perfect every time, whether you’re a seasoned baker or new to making frosting from scratch:
- Ensure Butter is Properly Softened: This is perhaps the most crucial step for smooth frosting. Take your butter out of the fridge at least 30-60 minutes ahead of time, or even longer if your kitchen is cool, to allow it to soften to room temperature. Properly softened butter is still cool to the touch but soft enough that your finger leaves an indent easily. If it’s too cold, your frosting will be lumpy and grainy. If it’s too warm (melted or greasy), the frosting can separate or become too thin.
- Can I Use Chunky Peanut Butter? Technically, yes, this recipe will work with chunky peanut butter. However, I only recommend using the chunky variety if you don’t intend to pipe the frosting, as the small peanut pieces will inevitably clog the tip of your piping bag. If you’re simply planning to spread the frosting with a knife, chunky peanut butter can add a delightful textural element.
- Adjust the Consistency to Your Needs: The beauty of homemade frosting is its adjustability. For a thicker, stiffer frosting that’s ideal for intricate piping or filling dense layers, gradually add a tablespoon or two more powdered sugar. For thinner frosting, perfect for glazing or simple spreading, add more milk (or cream), one tablespoon at a time, until you achieve your desired consistency. Always adjust slowly, as a little goes a long way.
- Avoid Overbeating the Frosting: While whipping the frosting well is important for achieving a light and airy texture and stiff peaks (similar to stabilized whipped cream), don’t go overboard. Over-whipping buttercream can incorporate too much air, causing it to become unstable, split, or curdle, resembling cottage cheese. If this happens, don’t despair! Try stirring in additional milk by hand, one tablespoon at a time, or gently re-whip on very low speed, to see if the frosting will smooth out again. Sometimes, chilling it for 15-20 minutes and re-whipping can also help.
Delicious Flavor Variations & Add-Ins
While this classic peanut butter frosting is perfect as is, it’s also a fantastic base for creativity! Here are a few ideas to customize your frosting and make it truly unique:
- Chocolate Peanut Butter Frosting: This iconic duo is always a winner. Simply add 1/4 to 1/2 cup of unsweetened cocoa powder along with the powdered sugar. Adjust for desired chocolate intensity and add a touch more milk if needed to maintain consistency.
- Maple Peanut Butter Frosting: Replace a tablespoon or two of the milk with pure maple syrup for a delightful autumnal twist. This adds a subtle sweetness and aromatic depth.
- Spiced Peanut Butter Frosting: Incorporate a pinch of cinnamon, nutmeg, or even a tiny amount of cayenne pepper for a warming kick. These spices pair beautifully with the nutty flavor of peanut butter.
- Crunchy Texture Add-ins: If you’re not planning to pipe the frosting, stir in mini chocolate chips, finely chopped roasted peanuts, or even crushed pretzels for an exciting textural contrast.
- Espresso Peanut Butter Frosting: Dissolve 1 teaspoon of instant espresso powder in the milk before adding it to the frosting for a sophisticated coffee-infused flavor.
Frequently Asked Questions About Peanut Butter Frosting
Grainy frosting is often a sign that your butter was too cold or the powdered sugar didn’t fully dissolve. Try placing the bowl of frosting in a warm (but not hot!) spot for about 5 minutes, then give it another good whip with your electric mixer. Ensuring your butter is at proper room temperature from the start is key.
As mentioned earlier, the most common culprit for oily frosting is using natural peanut butter, which tends to separate. Always opt for creamy, “no-stir” shelf-stable peanut butter. Additionally, older peanut butter, even creamy varieties, that has been sitting for a while can sometimes start to separate and contribute to an oily consistency.
I generally don’t recommend attempting to dye this frosting vibrant colors. Since peanut butter naturally has a golden-brown hue, adding food coloring will typically result in muddy, darker shades rather than bright, distinct colors. It’s best to embrace its natural, inviting color!

Yield: How Much Frosting Does This Recipe Make?
This recipe yields approximately 2 cups of deliciously smooth peanut butter frosting. This quantity is generally sufficient for a variety of baking projects:

- It will beautifully cover an 8-inch two-layer cake.
- It’s also perfect for frosting a 9×13 inch sheet cake or a batch of brownies.
If you’re planning a larger project or want extra for piping elaborate decorations, consider doubling the recipe.
Storage Tips for Freshness
Proper storage ensures your homemade peanut butter frosting remains fresh and delicious for future enjoyment:
- To Store at Room Temperature: Leftover peanut butter frosting can be kept at room temperature for up to 1 day. Ensure it’s stored in an airtight container to prevent it from drying out or absorbing other odors.
- To Store in the Refrigerator: For longer storage, transfer the frosting to an airtight container and refrigerate for up to 5-7 days. Before using, allow the frosting to come back to room temperature on the counter (this can take 30-60 minutes). Once it’s softened, give it a fresh whip with an electric mixer for a minute or two to restore its smooth, fluffy consistency.
- To Freeze: This frosting freezes exceptionally well! Store it airtight in the freezer for up to 1 month. When you’re ready to use it, thaw the frosting overnight in the refrigerator. Once thawed, bring it to room temperature on the counter and re-whip it with your electric mixer until it’s light and smooth again.
