I made a chocolate cake, but unfortunately didn’t gauge my cocoa powder well. I didn’t have enough to make my standard chocolate buttercream, so I improvised. Nothing goes better with chocolate than peanut butter, and this light frosting complemented my cake perfectly!
Frosting can be tricky – I spent years thinking I was just really bad at making it. My frosting was always drippy or goopy, and even if it tasted good, it always looked a little sketchy. Years ago, my mom showed me how to make the absolute best buttercream frosting ever (you can find the super-secret recipe here). Since then, I’ve been creating frostings based on that recipe. This peanut butter frosting adds the delicious nutty flavor to a frosting that holds its shape, pipes well, and crusts.
Peanut Butter Frosting
Ingredients
- 1 stick butter
- ½ cup creamy peanut butter
- ½ tsp vanilla
- 2 ½ cups powdered sugar
- 1 Tbsp milk
Instructions
- Beat butter and vanilla until fluffy.
- Add peanut butter and mix well.
- Add powdered sugar and milk and mix until desired consistency is reached.

I use this on my chocolate cupcakes but I also add 2-3 tbsp maple syrup, and instead of milk, I use 2 tbsp whipping cream.
Diane Homan
Ooh! That sounds so good! I might have to give it a try 🙂 Thanks for the idea.

Can’t wait to try this recipe, I’ll be using it for my son’s birthday cake! Just wondering if you know it makes enough to cover and go in between two 8in round cakes or if I’ll need to double it?
Diane Homan
I’d definitely double it. Good luck and happy birthday to your son!!

Just frosted banana blondies with this. Haven’t tried them yet, but I already snuck a taste of the frosting and it is delicious 🙂
Diane Homan
Sneaking frosting is always a solid choice 😉 Banana blondes and PB frosting sound like a great match!

I bet sifting makes the frosting even fluffier!

Do you use salted butter for peanut butter frosting or unsalted ?
Diane Homan
Unsalted — there’s typically plenty of salt in the peanut butter!
