Ingredients You’ll Need
Each ingredient in this simple Peanut Butter Frosting recipe is chosen for both taste and texture, ensuring you create a smooth, decadent, and utterly dreamy topping. Don’t skimp or swap—every element plays a special role in the final result!
- Creamy peanut butter: The star ingredient, providing all the rich, nutty flavor and signature velvety texture we crave.
- Unsalted butter, softened: Adds a luscious, airy body to your frosting and lets the peanut flavor shine without extra saltiness.
- Powdered sugar: Not just for sweetness, powdered sugar also gives the frosting its soft, fluffy structure—so important for easy spreading or piping.
- Vanilla extract: A subtle splash that rounds out all the flavors and brings a little warmth to the mix.
- Heavy cream or milk: Just a bit turns your frosting from thick to cloud-like, making it silky and spreadable.
How to Make Peanut Butter Frosting
Step 1: Cream the Peanut Butter and Butter
In a large mixing bowl, combine the creamy peanut butter and softened unsalted butter. Using an electric mixer, beat them together on medium speed until the mixture is very smooth and totally unified. This base is crucial for that signature Peanut Butter Frosting texture—no lumps allowed! Scrape down the sides of the bowl as needed for a perfectly even blend.
Step 2: Add the Powdered Sugar Gradually
Begin adding the powdered sugar, one cup at a time, making sure to beat the mixture well after each addition. This prevents the frosting from turning gritty and ensures it’s beautifully fluffy. The gradual approach might test your patience, but the payoff is in the ethereally smooth consistency. Don’t forget to start your mixer on low to avoid a sugar cloud!
Step 3: Stir in Vanilla Extract
Add the vanilla extract and beat until it’s completely incorporated. This tiny step is a flavor booster, giving your Peanut Butter Frosting that bakery-style nuance everyone loves. Vintage bakers swear by this tip for that “secret ingredient” layer of deliciousness.
Step 4: Adjust Consistency with Cream or Milk
Now, drizzle in the heavy cream or milk one tablespoon at a time, mixing well between each addition. You’re looking for a soft, spreadable texture—think thick enough to hold swirls on cupcakes but loose enough to glide effortlessly over a cake. If you prefer your frosting even lighter, use a touch more cream!
Step 5: Whip Until Fluffy
Kick the mixer up to high speed and beat for 1–2 minutes. Watch as your Peanut Butter Frosting transforms, turning from dense to irresistibly light and fluffy. This final whipping step fills the mixture with air, making each bite melt-in-your-mouth perfect. Once you see those charming little peaks form, you’re ready to frost anything your heart desires.
How to Serve Peanut Butter Frosting
Garnishes
Add an extra touch of fun and sophistication by topping your frosted treats with a handful of chopped roasted peanuts, mini chocolate chips, or a playful dusting of cocoa powder. These easy garnishes create contrast and crunch, just begging your guests to reach for seconds.
Side Dishes
Pair your Peanut Butter Frosting-adorned cakes or cupcakes with a cold glass of milk, a scoop of vanilla ice cream, or fresh fruit like sliced bananas or strawberries. The lightness of these sides balances the frosting’s richness, making each bite even more irresistible.
Creative Ways to Present
Don’t limit yourself to cakes alone! Pipe Peanut Butter Frosting onto brownies, whoopie pies, or sandwich between homemade cookies for a nostalgic treat. You can even dollop it onto waffles or swirl it through warm oatmeal for a decadent breakfast surprise.
Make Ahead and Storage
Storing Leftovers
Stash any leftover Peanut Butter Frosting in an airtight container in the refrigerator for up to five days. Before using again, let it sit at room temperature until it’s soft and spreadable. Give it a quick stir or whip for a few seconds to restore its fluffy texture.
Freezing
If you want to make a batch ahead of time, Peanut Butter Frosting freezes beautifully! Spoon it into a freezer-safe bag or container, pressing out as much air as possible, and store for up to three months. Thaw in the refrigerator overnight, then bring to room temperature before frosting.
Reheating
There’s no need to heat Peanut Butter Frosting in the traditional sense, but if it’s super firm from the fridge or freezer, you can microwave it in short 5-second bursts, stirring between each, until it’s smooth and creamy again without becoming runny.
FAQs
Can I use chunky peanut butter instead of creamy?
You can swap in chunky peanut butter if you love extra nutty bits in your frosting, but the final texture will be less smooth. It’s delicious for rustic cakes and adds fun bites of crunch!
Is it possible to make this Peanut Butter Frosting vegan?
Absolutely! Use a plant-based butter alternative and non-dairy milk (like almond or oat). Just double-check that your powdered sugar is vegan-friendly, and you’re all set with a dairy-free treat.
How do I fix frosting that’s too thick or too thin?
If your frosting is too thick, add a splash more cream or milk, a teaspoon at a time, until you reach the perfect consistency. If it’s too thin, beat in additional powdered sugar a couple tablespoons at a time until fluffy and spreadable.
Will this frosting work for piping detailed designs?
Yes! Thanks to its fluffy, yet sturdy consistency, Peanut Butter Frosting is great for piping swirls, rosettes, or borders on cakes and cupcakes. Chill it briefly if your kitchen is very warm for extra clean shapes.
What cakes or treats pair best with Peanut Butter Frosting?
This frosting is a dream with chocolate or banana cake, cupcakes, brownies, and even cookies. It also makes an amazing dip for pretzels or graham crackers, or as a filling between two shortbread cookies for a nostalgic sandwich treat.
