During a small get-together at a friend’s house, I noticed their little girl struggling to spread a thick layer of frosting onto a cupcake. Her tiny hands worked so hard, but the frosting was stubborn, clinging to the spoon like a glob of cement.
She looked up, frustrated, and said, “Why can’t frosting be soft like peanut butter?” Everyone laughed, but her comment stuck with me. On the drive home, it made me think—why not create a frosting that’s as creamy and smooth as peanut butter itself?
The next morning, I pulled out a jar of creamy peanut butter from the pantry, still smiling at her innocent remark. I decided to whip up a frosting that even little hands could spread without a fight. No complicated techniques, no odd ingredients—just a handful of basics, a little mixing, and a lot of heart.
After all, I had a luscious, fluffy peanut butter frosting that’s not only easy to work with but tastes like a dream. It’s rich, slightly salty, and sweet in the best way possible. Plus, it spreads like butter on a warm pancake—no struggle, no mess. That little girl unknowingly sparked a new favorite in my kitchen, and I couldn’t wait to share it.
Short Description
Creamy, fluffy, and packed with rich peanut butter flavor, this homemade Peanut Butter Frosting is perfect for cakes, cupcakes, brownies, and even straight off the spoon. Quick, simple, and irresistibly delicious.
Key Ingredients
- 1/2 cup butter, softened
- 1 cup creamy peanut butter
- 2 cups powdered sugar
- 1 teaspoon vanilla extract
- 1–2 tablespoons milk (optional, for desired consistency)
Tools Needed
- Large mixing bowl
- Electric hand mixer or stand mixer
- Spatula
- Measuring cups and spoons
Cooking Instructions
Step 1: Beat the Butter and Peanut Butter
In a large mixing bowl, beat the softened butter and creamy peanut butter together on medium speed until completely smooth and creamy. This usually takes about 2–3 minutes.
Step 2: Add the Powdered Sugar
Gradually add the powdered sugar, about 1/2 cup at a time, beating well after each addition. The mixture will start to thicken as you add more sugar.
Step 3: Mix in the Vanilla
Pour in the vanilla extract and continue beating until fully incorporated. The frosting should look fluffy and smell heavenly at this point.
Step 4: Adjust the Consistency
If the frosting feels too thick or stiff, add milk one tablespoon at a time, beating after each addition until you reach your desired creamy consistency. Be cautious not to add too much milk; you want it spreadable, not runny.
Step 5: Frost and Enjoy
Use immediately to frost your favorite cakes, cupcakes, or brownies. Spread it generously for that beautiful swirl and dreamy finish.

Mistakes to Avoid & Solutions
Mistake: Using cold butter
Solution: Always use softened butter at room temperature. Cold butter won’t blend properly and can leave lumps.
Mistake: Adding powdered sugar all at once
Solution: Gradually add powdered sugar in small amounts to avoid a powdery mess and achieve a smoother texture.
Mistake: Overbeating the frosting
Solution: Once the frosting is fluffy and light, stop mixing to prevent it from becoming greasy.
Mistake: Using natural peanut butter
Solution: Stick with traditional creamy peanut butter. Natural types separate too much oil and affect the texture.
Mistake: Not adjusting consistency
Solution: If the frosting feels too thick, add milk 1 tablespoon at a time. If too thin, beat in more powdered sugar by the spoonful.
Serving and Pairing Suggestions
– Frost chocolate cupcakes with a generous swirl and a sprinkle of chopped peanuts.
– Spread it between two cookies to make homemade peanut butter cookie sandwiches.
– Top warm brownies with a thick layer and a drizzle of melted chocolate.

Storage and Reheating Tips
Refrigeration: Store leftover frosting in an airtight container in the refrigerator for up to 5 days.
Bring to room temperature: Let the frosting sit out for about 30 minutes before using to soften.
Freezing: Freeze in a sealed container for up to 2 months. Thaw overnight in the fridge before bringing to room temperature.
Rewhipping: If frosting seems stiff after storage, beat it again with a mixer for a few seconds to restore creaminess.
FAQs
1. Can I use chunky peanut butter instead of creamy?
You can, but it will create a textured frosting rather than a smooth one. Great if you love a little crunch!
2. Is it possible to make this frosting vegan?
Yes! Swap the butter for a plant-based butter alternative and ensure your powdered sugar is vegan-friendly.
3. How can I make the frosting less sweet?
Reduce the powdered sugar slightly and add an extra tablespoon of peanut butter to balance the flavor.
4. Can I pipe this frosting onto cupcakes?
Absolutely. It’s thick enough to hold its shape when piped but creamy enough to glide easily through a piping bag.
5. Can I make it ahead of time?
Yes. Make it up to 2 days in advance, store it in the fridge, and rewhip before using.
Tips & Tricks
– Sift powdered sugar before adding to avoid lumps.
– Use a paddle attachment if using a stand mixer for the smoothest texture.
– Add a pinch of salt if your peanut butter is unsalted to enhance flavor.
– For extra flavor, stir in a tablespoon of cocoa powder for a peanut butter-chocolate twist.
– Frost your cakes or cupcakes when they are completely cool to prevent melting.
Recipe Variations
Chocolate Peanut Butter Frosting
Add 2 tablespoons of unsweetened cocoa powder when beating in the powdered sugar. The result is a rich, chocolatey peanut butter dream.
Honey Peanut Butter Frosting
Swap 1/4 cup of the powdered sugar for 2 tablespoons of honey. It gives a slightly floral sweetness and a softer finish.
Cinnamon Peanut Butter Frosting
Mix 1 teaspoon of ground cinnamon into the frosting for a warm, spiced flavor that’s perfect for fall treats.
Crunchy Peanut Butter Frosting
Use chunky peanut butter instead of creamy. Stir in extra chopped roasted peanuts for added texture and a satisfying crunch.
Espresso Peanut Butter Frosting
Dissolve 1 teaspoon of instant espresso powder in the vanilla extract before adding. It adds a subtle coffee undertone that pairs beautifully with chocolate desserts.
