Ultimate Peanut Butter Frosting Recipe

This ultimate peanut butter frosting recipe is perfect for a chocolate layer cake, apple dipping, or spreading on graham crackers!

Peanut Butter Frosting and Chocolate Cake

For years, I’ve made cakes but they were always one layer, left in the pan, and about as simple as a cake can get. My baking skills have improved with a lot of practice! Since COVID-19 has closed our eateries here in Tennessee (except for take-out/curbside pick-up), I decided to make a homemade cake for my husband’s 45th birthday. Our tradition is to buy an ice cream cake. I think he likes our new tradition a little better!

He loves Reese’s Peanut Butter Cups and I wanted to create something he wouldn’t forget! My cake building and decor skills could still use some improvement; however my family would testify that it tastes amazing. Shockingly, I’ll be the first to tell you to cut small pieces. It’s delicious but also quite sweet!

After creating my Chocolate Layer Cake last year, I knew it would be the perfect base to try out my frosting. Previous recipes I’ve tried for chocolate cake always ended up dry and flavorless. This cake is exactly the opposite and truly amazing with any kind of frosting.

The best I have for creating perfect cakes time and time again is to bake with love. Secondly, you’ll need proper pans. Personally, I love USA Pan’s 9-inch round cake pans. They feature a unique design to facilitate air circulation for even baking. They also clean up really well!

I sprayed the pans with coconut oil, dusted them with flour and placed a round piece of parchment in the bottom. After filling the pans, I gently tapped each one on the counter to remove air bubbles. The cakes were even and didn’t crack.

Ultimate Peanut Butter Frosting Ingredients:

Directions:

Using a electric mixer (or stand mixer with paddle attachment), cream the peanut butter and salted butter together until smooth. Scrape the sides and bottom of the bowl and finish mixing another minute.

Alternating between the powdered sugar and milk, add a small amount at a time, beginning and ending with powdered sugar. Stop the mixer to occasionally scrape the sides.

Once fully incorporated, add the vanilla and mix well.

If the frosting is too thin, add more powdered sugar, one tablespoon at a time. If the frosting is too thick, add a tablespoon of milk at a time. Mix well after each addition.

Frost your cake and enjoy!
