What You’ll Need for Peanut Butter Buttercream Frosting

1 cup (8oz/225g) unsalted butter (softened to room temperature for easy mixing)
1 cup (8oz/225g) creamy peanut butter (use natural or regular, but ensure it’s at room temperature)
3 cups (12oz/340g) powdered sugar (sifted to avoid lumps)
2 tablespoons milk (any type works, or substitute with non-dairy milk)
1 teaspoon vanilla extract (for added flavor)
½ teaspoon salt (to balance the sweetness)

How to Make Peanut Butter Buttercream Frosting

In the bowl of a stand mixer fitted with a whisk attachment (or using a handheld electric mixer), combine the butter and peanut butter. Whisk on medium-high speed for 3-4 minutes until light and fluffy.
Reduce the mixer speed to low and gradually add the powdered sugar, a little at a time, until fully incorporated. Scrape down the sides of the bowl as needed.
Add the milk, vanilla extract, and salt. Whisk on medium speed for 1 minute until smooth and well combined.
Use the frosting immediately, or store it at cool room temperature for up to one day. For longer storage, refrigerate and bring it back to room temperature before using for the best spreading consistency.

Perfect Pairings: What to Frost with Peanut Butter Buttercream

This rich and creamy frosting is a match made in heaven for chocolate cupcakes, brownies, or even a classic vanilla cake. For a fun twist, try it on banana bread or sandwich cookies. It’s also delicious as a dip for fresh fruit like apple slices or strawberries!

Storage Secrets: Keeping Your Frosting Fresh

Store leftover frosting in an airtight container in the fridge for up to one week. If you’ve frosted a cake, cover it loosely with plastic wrap to prevent drying. Before using chilled frosting, let it sit at room temperature for 30 minutes and give it a quick whisk to restore its fluffy texture.

Quick Swaps: Easy Recipe Variations

For a nut-free version, swap the peanut butter with sunflower seed butter. If you prefer a sweeter frosting, add an extra ½ cup of powdered sugar. For a hint of indulgence, mix in ¼ cup of melted chocolate or a sprinkle of cocoa powder for a chocolate-peanut butter twist.

Time-Saving Tips for Busy Bakers

To speed up prep, soften butter quickly by cutting it into cubes and letting it sit at room temperature for 10 minutes. Use a fine-mesh sieve to sift powdered sugar directly into the mixing bowl—it’s faster and ensures a smoother frosting. Double the batch and freeze half for future baking projects!

Essential Tools: What You’ll Need

A stand mixer with a whisk attachment is ideal for achieving that light, fluffy texture, but a handheld electric mixer works just as well. Use a rubber spatula to scrape down the sides of the bowl to ensure everything is evenly mixed. A measuring cup with a spout makes adding milk mess-free!
