I loved this frosting. I did not however put it on brownies. I made the frosting for a chocolate cake and I had no left overs. I did make a slight change though. I added 1 1/2 - 2 cups of peanut butter chips and just dumped it on top of a chocolate cake that was still in baking dish. The frosting will ooze down the sides of dish. This is a great peanut butter frosting recipe.

I didn't have peanut butter chips, but I did have swirled milk chocolate and peanut butter chips and what a happy surprise that turned out to be! After tasting these I know I will always make the frosting this way! I also replaced 1/4 c. of the butter with 1/4 c. peanut butter and let me tell you, the result was this beautiful, gooey "stuff" that looked like caramel ice cream topping. Thinking the brownies could use a little garnish or decoration, I sprinkled more of the swirled milk chocolate and peanut butter chips over the top. So pretty! Taste is what really matters, however, so I cut myself a tiny piece to "test" them and man oh man, what another happy surprise! I didn't expect them to be THAT good! This milk chocolatey, peanut buttery frosting sets up nicely in the refrigerator but is still gooey, and is the perfect finish on the chewy, fudgey brownie beneath. That "taste" was so darn good it ended up being the equivalent of two brownies. My only criticism is that the title doesn't do these deliciously decadent brownies justice!

This recipe for peanut butter frosting is the best frosting recipe I have ever used!!! The only reason it got 5 stars is because I dont have the option of giving it more! It is incredibly easy and absolutely heavenly! It has a wonderfully sweet and rich peanut butter taste without being overpowering. I use it for any chocolate cake, loaf, muffin or brownie that I make. It has become a stand by in my household.

This frosting is great. I did add a few spoonfuls of peanut butter too. I would like to try this on a real brownie recipe though.

My teenage son and his friends loved this wonderful brownie. The peanut butter topping is amazing! I sent it on a ski trip and these are the only ones that they ate. I will always keep this recipe in my file for a quick and easy dessert.

I tried this for everybody at work and it was a super hit.

I made this receipe exactly as it was written, and they were FANTASTIC! I will absolutely be making these again (and again)! Someone mentioned you have to eat these with a glass of milk, my sugestion is with a glass of red wine! Yum.

The taste is yummy but I think it is missing something to make this recipe come together. I am not a nut person but maybe pecans with this would give the brownie a turtle like taste. It is very gooey (even though I kept them in the fridge the entire time) and hard to cut but manageable. With that said they were eaten quite fast in this house. Thank you

I made these for my boyfriend's birthday (he LOVES peanut butter). He rated this as a 4 star brownie. I did add a healthy dollop of peanut butter to the frosting to make sure it had a nice peanut flavor. I like these best when they're cold because the peanut butter isn't so overwhelming, but bf likes them better warm. **UPDATE** I had to change this to 5 stars because my boyfriend took these to work and his coworkers said they would pay me to make these again this week. If a bunch of grown men offer to pay $20 for a brownie, it's gotta be a 5 star. :)

This is delicious...I used other's reviews and chilled after spreading the topping on, and it was easy to cut. Also, I added a tablespoon of Peanut butter, which made it nice and tasty... Great recipe, easy to make!

DELICIOUS! Definitely keep it in the refrigerator though or else it is too gooey to cut. Since I tried this, I can't make brownies without making this too!

I thought this recipe was great and it is not runny if you refrigerate the brownies after you have added the frosting. I found it firms up but not as hard as fudge. Really, really good. Will be using this as a frosting on my brownies once in awhile, just for a change.

Super good! I couldn't stop licking the spatula after I spread the frosting on the brownies. I put about 2 tablespoons of peanut butter in with the chips and butter, just to assure a good peanut butter flavor. Once spread in the pan, I drizzled Hershey's Syrup across the top and then dragged the tip of a knife through it to make a pretty design. I kept it in the refrigerator till the frosting set up but I think that it tastes better at room temperature. Either way, the frosting wasn't runny. To be honest though, I think the frosting would be better on a Texas Sheet Cake than it is on the brownie.

These were good but *very* rich. I also recommend making a 13x9 inch pan of brownies because the topping makes so much.

After reading over the ingredient list, I realized that these brownies have to be refridgerated. They turn out great everytime, the topping is soft and creamy, and it holds up well when cut with a knife. They make a great presentation at a party. The other reviewers obviously didn't realize that when chocolate chips, butter and sweetened condensed milk cool in the refridgerator that they harden a bit. This is not a "sloppy mess".

Well depending on who you ask, my husband thought the peanut butter fudge overpowered the browning. I thought the brownie was only there as a way to get the fudge. It was very gooey, but after an over night stay in the fridge I didn't have any other problems with them. They do lend themselves better to eating with a fork though rather than by hand.
