- Unsalted butter: Using softened unsalted butter ensures a creamy base without overpowering the peanut flavor.
- Creamy peanut butter: Choose smooth for the silkiest frosting that spreads beautifully.
- Powdered sugar: Gradually added to control sweetness and create a fluffy texture.

How to Make Peanut Butter Frosting Recipe
Step 1: Cream the Butter and Peanut Butter
Begin by beating the softened unsalted butter and creamy peanut butter together in a large bowl until you achieve a smooth and creamy blend. This is the foundation of your frosting, and taking the time to get this step right helps ensure a luscious texture that’ll spread effortlessly over your favorite treats.
Step 2: Add the Powdered Sugar
Gradually mix in the powdered sugar, adding about half a cup at a time. Continue beating after each addition until the frosting is silky smooth. This slow incorporation helps prevent lumps and lets you adjust how sweet and thick your frosting becomes, depending on your preference.
Step 3: Incorporate Milk and Vanilla Extract
Now stir in the milk and vanilla extract. The milk softens the frosting, giving it that perfect spreadable consistency, while the vanilla infuses a warm undertone that lifts the entire flavor. Feel free to add a bit more milk if you want it thinner or more spreadable.
Step 4: Add a Pinch of Salt (Optional)
Sprinkle in a tiny pinch of salt if you want to balance the sweetness and enhance the peanut butter’s natural richness. It’s a subtle tweak that makes a noticeable difference, especially if you love that sweet-and-salty combo.
Step 5: Use or Store
Your Peanut Butter Frosting Recipe is now ready to be used! Slather it generously on cupcakes, cakes, or cookies. If you’re not using it immediately, store it in an airtight container in the fridge for up to a week and bring it back to room temperature before serving to restore that creamy texture.
How to Serve Peanut Butter Frosting Recipe

Garnishes
Enhance your frosting by adding sprinkles, chopped peanuts, or a drizzle of melted chocolate on top. These garnishes not only add visual appeal but also introduce delightful textures and complementary flavors that elevate your dessert experience.
Side Dishes
This peanut butter frosting pairs beautifully with classic vanilla or chocolate cakes, banana bread, or even simple sugar cookies. For a fun twist, serve it alongside freshly sliced apples or celery sticks for a sweet and savory snack that everyone will love.
Creative Ways to Present
Why stop at spreading? Use a piping bag to create decorative swirls on cupcakes or cakes. You can also layer it between cake layers for a rich surprise inside or dollop it onto warm brownies or waffles for an indulgent treat that’s as impressive as it is delicious.
Make Ahead and Storage
Storing Leftovers
If you have leftover frosting, no worries! Pop it into an airtight container and keep it in the refrigerator. It will stay fresh and ready to use for up to a week. Just be sure to bring it back to room temperature and give it a quick stir to smooth it out before spreading.
Freezing
For longer storage, this Peanut Butter Frosting Recipe freezes wonderfully. Store it in a sealed freezer-safe container for up to 3 months. Thaw it overnight in the fridge and then let it reach room temperature before using to make spreading easy again.
Reheating
If your frosting feels a bit stiff after chilling or freezing, simply let it warm on the counter for 15-20 minutes. You can also give it a quick gentle whisk or stir to bring back that creamy texture without altering the flavor.
FAQs
Can I use natural peanut butter for this frosting?
Absolutely! Natural peanut butter will add a slightly different texture and more intense peanut flavor. Just make sure to stir it well before mixing, as natural versions tend to separate. You might need to adjust powdered sugar or milk to get the perfect consistency.
Is there a way to make this frosting vegan?
Yes, swap the unsalted butter for a plant-based vegan butter and use a non-dairy milk like almond or oat milk. Make sure your powdered sugar is vegan-friendly. The rest of the ingredients are naturally vegan, so it’s a simple switch.
How thick should the frosting be for spreading versus piping?
For spreading, a slightly thinner consistency that can easily glide over your cake or cupcakes is ideal—add a bit more milk if needed. When piping, keep it a bit thicker so the frosting holds its shape well and doesn’t run.
Can I add other flavors to this Peanut Butter Frosting Recipe?
Definitely! A dash of cinnamon, a tablespoon of cocoa powder, or even a splash of bourbon can add exciting layers of flavor. Just add these gradually and taste as you go to keep the frosting balanced and delicious.
What desserts work best with this peanut butter frosting?
This frosting shines on classic vanilla or chocolate cakes, peanut butter cookies, banana bread, and even brownies. It adds a creamy, nutty richness that complements sweet or slightly salty desserts beautifully.

- 1 tsp vanilla extract
- Pinch of salt (optional, to balance sweetness)
Instructions

- Add the Powdered Sugar: Gradually incorporate the powdered sugar, adding it 1/2 cup at a time, while continuously beating to ensure smoothness. Adjust the amount of powdered sugar to reach your preferred frosting sweetness and consistency.
- Add Milk and Vanilla: Stir in the milk and vanilla extract into the mixture. Beat thoroughly until the frosting becomes smooth and creamy. Add more milk if you desire a thinner frosting consistency.

Notes
- You can adjust the thickness of the frosting by adding more powdered sugar for a stiffer frosting or more milk for a thinner one.

- Make sure the butter is properly softened to avoid lumps in the frosting.
- If storing in the refrigerator, bring to room temperature and rebeat to restore the creamy consistency before use.
