  1. Place the butter and peanut butter into a medium bowl, and beat with an electric mixer. Gradually mix in the sugar, and when it starts to get thick, incorporate milk one tablespoon at a time until all of the sugar is mixed in and the frosting is thick and spreadable.

This is 3 stars if you make it as written, which I did. But it was very hard to spread, even on a 9 x 13 sheet cake. I couldn't even imagine trying to frost a layer cake with it like this. So, I decided to chalk that cake up to experience and made another. This time I used a heaping cup of Jif peanut butter (probably around 1 1/4 cups), 1 1/2 cups of powdered sugar and 3 T of heavy cream. I beat the room temperature butter and the room temperature peanut butter for several minutes until I could not see any butter at all in the mixture and it seemed very creamy. Then I gradually added the powdered sugar and when it was well-blended, I added the 3 T of heavy cream and then put it on #6 on my KitchenAid mixer and let it go for 3-4 minutes. This time it was MUCH easier to spread and tastes great!!


DELICIOUS! This recipe deserves nothing less than 5 stars. Naturally you wouldn't expect any kind of peanut butter frosting to spread as pretty as butter cream and still taste like peanut butter, this is "peanut butter" we're talking about after all. My cake tasted fabulous and looked fabulous. It is not anything like a paste, if you follow the recipe correctly, and add milk "as needed" like it says and whip it long enough, its perfect. Major pet peeve....someone leaving a review when clearly they did not follow the recipe like it is written, how can you review this recipe if you didn't follow it? This went in my GOLDEN RECIPE BOOK. Frosted brownies with it, oh la la, Loved it!!


Very easy and nice. However, in order to get a good consistency, all ingredients should be at room temperature. If they get too grainy and hard after u added in 3 tablespoons milk, stop adding. Instead, put ur bowl into microwave on high for 30 sec, take out and stir. This will solve the problem. Great frosting. Very peanut buttery!
