Very tasty recipe. A little temperamental though. Here are some tips to avoid frustration. 1) Your frosting mixture should be at a gentle simmer (or it may burn) so adjust the heat accordingly. I had to use med-low since med-high was bubbling way too furiously. 2) Melt and mix butter, cream, peanut butter, and vanilla first, then gradually mix in sugars. 3) Taste test as you add the sugars: I found 1 cup of each type to be plenty sweet, so I left out the 2nd cup of confectioners' sugar. 4) Keep gently simmering and stirring constantly (not frequently) until all sugar is dissolved. 5) Spread quickly and use the back of a spoon to pound it out if necessary. As stated in the recipe, quick spreading is important. As it cools (quickly) the PB oil makes the frosting not want to stick very well. It just wants to peel right off. Fortunately, my brownies were 95% covered by then with only a little unevenness, so I took the back of a spoon and pounded it even. It was my first time making this recipe and it came out awesome with the mentioned modifications. I gave it 4 stars because I really didn't change much, I just had to take a few unmentioned steps.

I must have done something wrong - mine looked awful and wasn't really soft and creamy like I was hoping for.

no need to buy heavy cream since milk or half & half works fine too.

I had my doubts when I read the recipe that this would be the fluffy frosting I was looking for. After making it I was pleasantly surprised and loved it on the brownies that I had made and added peanut butter chips to. I could almost eat just the frosting. Love it!

Added extra peanut butter and used milk. Great on mocha brownies.

I used this recipe and tweaked it just a bit ... I added more fresh cream with the powdered sugar to make it less fudge-y and more frosting-y! :) It came out just fine. I also a full 1/4 cup of peanut butter because it needed a little more taste to balance the brown sugar.

Very good ! i also left out 1 cup of the confectioners' sugar, and it was plenty sweet, it was probably also easier to spread. It will burn quickly, be sure to stir constantly !! Be sure to sift powder sugar.
