My recipe story
My love for peanut butter frosting started when I was a child, watching my grandmother bake towering chocolate cakes. Instead of traditional chocolate or vanilla frosting, she would sometimes whip up a peanut butter frosting that had everyone sneaking spoonfuls from the mixing bowl. As I grew older, I found myself recreating that nostalgic flavor in my own kitchen. After testing countless versions—some too sweet, some too dense—I finally developed this recipe that achieves the perfect balance of fluffy texture, peanutty richness, and spreadable consistency. It’s a family favorite and a go-to for birthdays, holidays, and casual baking days alike.

Ingredient breakdown
This frosting requires just a handful of ingredients, but each one plays an important role in achieving the perfect texture and taste. Let’s break down the essentials so you know exactly what makes this frosting work.
Unsalted butter: The base of the frosting, butter provides richness and structure. Make sure it’s softened to room temperature so it whips smoothly into a fluffy consistency. Unsalted butter allows you to control the saltiness of the final product.
Creamy peanut butter: Use a no-stir creamy peanut butter for the smoothest, fluffiest results. Natural peanut butters that separate with oil can cause the frosting to split or become too greasy. Classic brands like Jif or Skippy work perfectly here.
Powdered sugar: This not only sweetens the frosting but also stabilizes it, giving body and structure. Sift it beforehand to avoid lumps and achieve that professional bakery finish.
Vanilla extract and milk or cream: Vanilla adds warmth and depth, while a splash of milk or cream helps adjust consistency. For a richer frosting, opt for heavy cream instead of milk.
Equipment you’ll need
- Electric mixer (stand mixer or hand mixer)
- Large mixing bowl
- Rubber spatula
- Measuring cups and spoons
- Sifter for powdered sugar
- Piping bag and tips (optional, for decorating)
Step-by-step directions
- Cream the butter and peanut butter: Place the softened butter and creamy peanut butter into a large mixing bowl. Using an electric mixer, beat them together on medium speed until the mixture is light, fluffy, and fully combined. This should take about 2–3 minutes and will ensure the frosting has a smooth, airy base.
- Add the powdered sugar: Gradually sift in the powdered sugar, about one cup at a time, mixing on low speed after each addition. This prevents sugar clouds from filling your kitchen and helps the frosting come together evenly. Continue mixing until all sugar is incorporated and the frosting looks thick.
- Add vanilla and liquid: Pour in the vanilla extract and 1–2 tablespoons of milk or cream. Beat on medium speed for another minute until everything is fully blended. If the frosting is too stiff, add a little more milk, one teaspoon at a time, until it reaches your desired consistency.
- Whip to perfection: Increase the mixer speed to medium-high and beat for 2–3 more minutes. This final whip incorporates air, giving the frosting a fluffy, cloud-like texture. Scrape down the sides of the bowl with a spatula to make sure everything is evenly mixed.
- Frost your desserts: Use immediately to frost cakes, cupcakes, brownies, or cookies. For piping, transfer the frosting into a piping bag fitted with your favorite tip. The frosting will hold its shape beautifully for swirls, rosettes, and borders.
Variations & substitutions
If you want to put your own spin on this frosting, there are plenty of ways to adjust it without compromising its creamy texture.
- Chunky peanut butter: Swap creamy for chunky if you love a little crunch in your frosting.
- Chocolate peanut butter frosting: Add ½ cup of cocoa powder along with the powdered sugar for a rich chocolate twist.
- Honey-sweetened: Reduce the powdered sugar slightly and add a tablespoon of honey for a naturally sweet flavor.
- Dairy-free: Use vegan butter and a splash of almond or oat milk for a dairy-free alternative.
💡 Expert Tips & Troubleshooting
- If your frosting is too runny, add more powdered sugar one tablespoon at a time until thickened.
- Too sweet? Add a pinch of salt to balance out the flavor.
- For the fluffiest frosting, always whip for an extra 2–3 minutes at the end.
- If the frosting becomes grainy, it’s likely due to natural peanut butter—stick with no-stir varieties for best results.
- Chill your mixing bowl before whipping if your kitchen is warm, as butter can soften too quickly.
Storage, freezing & make-ahead
This frosting can be made ahead of time, making it perfect for party prep. Store it in an airtight container in the refrigerator for up to 5 days. When ready to use, let it come to room temperature and re-whip for a minute to restore its fluffy texture. For longer storage, freeze the frosting in a freezer-safe container for up to 2 months. Thaw overnight in the fridge and whip again before using. If piping, transfer to a piping bag just before decorating for the best results.
Serving ideas & pairings
This frosting is incredibly versatile and pairs with a wide variety of baked goods. Spread it generously over chocolate cake for a classic pairing, or frost banana bread cupcakes for a sweet and nutty twist. It’s also fantastic as a filling between sandwich cookies or swirled on top of brownies. For something fun, try piping it onto sugar cookies and topping with mini chocolate chips. Pair it with a glass of cold milk, hot coffee, or even a drizzle of chocolate syrup for a decadent finish.
FAQ
Can I use natural peanut butter?
It’s best to avoid natural peanut butter that separates, as it can cause the frosting to split. Stick with no-stir creamy peanut butter.
How do I make the frosting less sweet?
You can reduce the powdered sugar slightly, but this may affect texture. Adding a pinch of salt also helps balance sweetness.
Can I make this frosting without a mixer?
While a mixer makes the process easier, you can whip it by hand with a whisk and some elbow grease—it just won’t be quite as fluffy.
Will this frosting hold up for piping?
Yes! This recipe pipes beautifully and holds its shape for swirls, rosettes, and borders.
Can I color this frosting?
Since it has a natural tan color from the peanut butter, darker gel-based food colors work best if you want to tint it for themed desserts.
