Jump to Recipe

It never even crossed my mind to make peanut butter frosting. I know, crazy, but true. Somehow as a child I was just not excited about peanut butter as anything other than something you put on bread or apples.

Sometime in my early 20s I discovered peanut butter and chocolate – then it was off to the races. A few years ago I was making a wedding cake for a friend’s daughter and they asked me to fill it with their treasured family recipe for “peanut butter fluff.” Say what???!!!???

Really Good Peanut Butter Frosting

I got the recipe, made up a batch and was blown away! It was essentially a peanut butter buttercream and it was awesome. I have been making it ever since, almost the same way they do. When I frost a cake with peanut butter frosting I just can’t resist a little milk chocolate drizzle on top so I have included those instructions also.

Depending on your passion for drizzling you might have some of the good stuff left over. If so never fear – just eat it or refrigerate the leftovers and warm them up to top your ice cream. It is ridiculously good on cherry ice cream!

Chocolate Cakes Worthy of Peanut Butter Frosting

A big wedge of chocolate cake is covered in peanut butter frosting and then drizzled with milk chocolate drizzle. The rest of the cake is on a clear glass cake plate in the background.

Fluffy Peanut Butter Frosting With Milk Chocolate Drizzle

It takes less than 10 minutes to make the frosting. The milk chocolate drizzle also takes less than 10 minutes. I can make both in about 15 minutes. Makes enough frosting for a two layer cake or about 24 cupcakes with generous frosting (the only way I like 'em!) I also love this frosting on apples or graham crackers.

Ingredients

For the Peanut Butter Frosting

1/2 cup salted butter softened
1 pound powdered sugar
1 cup heavy cream
1 1/4 cups peanut butter creamy or chunky
2 tsp. vanilla extract

To Make the Milk Chocolate Drizzle

½ cup salted butter
1/3 cup milk
4 Tbsp. unsweetened baking cocoa
1 pound powdered sugar
1 Tbsp. vanilla extract

Instructions

In the bowl of a stand mixer fitted with the whip, beat the butter and powdered sugar on high until creamed.
Add the heavy cream and beat on medium-low until combined.
Add the peanut butter and vanilla. Beat on high, scraping sides of bowl as needed until frosting is light and fluffy and completely mixed.
To make the Milk Chocolate Drizzle: Before starting the drizzle frost your cake or cupcakes because the drizzle needs to go on hot as soon as it is done.
In a medium sauce pan over medium heat add the butter, milk and cocoa. Whisk until the mixture comes to a simmer and then simmer for 30 seconds.
Remove pan from heat and whisk in powdered sugar until no lumps remain. Whisk in vanilla and drizzle hot over frosted cake or cupcakes.
