What kind of peanut butter should you use for peanut butter frosting
We recommend using a traditional creamy peanut butter like Jiff, Skippy, or Peter Pan in this homemade peanut butter frosting. Natural peanut butters that need to be stirred tend to have a higher oil content and are a little more volatile in frosting. Some of them work, but more often than not we found they led to split icing.
How to make peanut butter frosting
Peanut butter frosting is super simple to make, but we’ll break it down step by step to take any and all guess work out, so you’re guaranteed perfect frosting every darn time.
1. Combine the peanut butter and butter in a stand mixer fit with the paddle attachment.
2. Beat together until creamy and homogenous.
3. Scrape down the bowl and add the powdered sugar, heavy cream, and vanilla extract. Mix well.
4. Scrape down the bowl to make sure everything is mixed together. Beat on high speed for 2 minutes or until light, fluffy and creamy.
Et voila! PB frosting for all your peanut butter-y dessert needs!
How to prevent peanut butter frosting from splitting
Now if you’d ever tried to make peanut butter frosting before you might have found it be just a smidge finickier than other frosting recipes. This is because peanut butter frosting calls for two different fats and peanut butter can vary a lot by brand. Sometimes this can lead to your frosting splitting. Which is, like, a day ruiner in my opinion. Lucky for you we tested the sh*t out of this peanut butter frosting, so you can rest easy, knowing it’s going to turn out creamy and silky smooth every time.
Make sure your peanut butter and butter are the same temperature: Room temperature butter and room temperature peanut butter will mix together seamlessly without any weird chunks of cold butter or melted peanut butter.
Use heavy whipping cream: Milk, water, or any other liquid simply won’t cut it in this recipe. Just two Tablespoons of cream will keep your frosting light, fluffy, and extra creamy.
Use the paddle not the whisk: We found the amount of air that the whisk attachment beats into the frosting led to split frosting. The paddle will consistently beat up a fluffy frosting that still holds it shape.
Perfect pairings for peanut butter icing:
Chocolate Cake: While I’ll always be a chocolate cake with chocolate frosting girl, there’s a special place in my heart for chocolate cake with pb frosting. Want both? Fill the inside of the cake with peanut butter frosting and frost the outside with chocolate for a fun and nutty surprise!
