These are really good and take minimal additional effort from baking box (or your favorite scratch recipe) brownies. We prefer Ghiradelli brownies, so that's what I used (and used an 8X8 glass pan since they are a smaller yield). I halved the PB and chocolate toppings to make up for the smaller pan. I wasn't sold on the PB when I licked the beaters, but it really works on the brownies. I'm super lazy, so I nuked the chocolate chips and butter for 45 seconds before pouring them over the PB layer. I'll definitely make these again! THANKS for the recipe!

I made these for opening day of the OSU Buckeyes football season. They were a big hit. My changes- I put my butter and Peanut butter in a bowl and microwaved on medium for 1 minute tile the PB was softened and then mixed the confectioners sugar and 1 TBSPN of Vanilla in and beat. I've made buckeye balls and this is how I do them also.

This was the Recipe Group choice for July 2015 and I am a bit late in preparing it. We used the "Duncan Hines dark chocolate fudge brownie" mix.(18.2 ounce box). There is no way the three of could consume the whole recipe (or at least we shouldn't) so I cut the recipe in half. I used a kitchen scale to measure half of the mix accurately. We used an 8x8 glass pan. It was fun to make and very good. I have to admit that we altered the last step. Instead of melting the chocolate chips with butter, we omitted the butter and sprinkled the un-melted milk chocolate chips on top of the peanut butter mixture. TIP-Before you measure the peanut butter, spray the measuring cup with baking spray or wipe the butter wrapper inside the cup so the peanut butter slides out easier. Works for us. As other's mentioned, it is very rich. But we'll be making it again. Thanks for the recipe!

i didn't have a box of brownie mix on hand so made the brownies from scratch. and i had some leftover chocolate butter cream frosting i needed to use up, so i heated it up and let it boil about 2 mins and it turned into the most fabulous fudge for the topping. but this concept/recipe is fantastic!! so rich, fudgey and yummy!!

These are very tasty and have a great visual presentation. I received a lot of compliments that these looked professional because of the well-defined layers and the nice and neat edges to the smooth chocolate topping. I used my grandma's brownie recipe instead of boxed brownies and dark chocolate chips in the topping, but otherwise followed the recipe exactly. They have already become part of my treat rotation for pot lucks and when I have company.

First of all I have to call them Wolverine Brownies....no disrespect for my Ohio State brethren haha! Really really good but I cut the powdered sugar in half and they were still plenty sweet. If you dont like insanely sweet treats I suggest you do same. With that one change I will make these many more times!!!

These were so good and so easy! We have dairy allergies in our family, so we substituted plant butter and enjoy life chips. Delicious!

A little goes a long way with these brownies, as they are super rich and sweet! I followed the recipe exactly, using a 9/13 pan. We liked them but the consensus was that they were a little too sweet for our liking. Maybe next time I will cut back on the powdered sugar. Thanks for sharing your recipe, Cindy Yonkman!

These were really tasty, rich but tasty. I used the Best Brownie recipe on AR instead of a box for the brownie. I halved the filling and ganache since I was making a 9x9 pan. The filling was really dry so I added 2 tbsps of 5% cream, I used natural unsweetened/unsalted PB so that may be why. Definitely will make again when craving a PB treat.

I make with triple chunk brownie mix and Simply Jif peanut butter. I also use Ghirardelli semi-sweet chocolate chips. These are very rich so be sure to cut them into small squares, a little goes a long way!

Brought these to a bake sale and they looked nice. Could have been a bit more sturdy for the sale. I put chopped Reese’s pieces on top for the decoration. They were Delicious!

Followed the box recipe for the brownies and then followed this recipe as written except I did sift my powdered sugar. This is a fantastic recipe and will be making it again!! My best friend even texted me to scold me for bringing her more than one cuz she couldn't leave them alone! Lol You can leave these on the counter for a while to soften everything or refrigerate them. Both ways are so good!

Like a peanut butter cup brownie!. My only issue is they tend to call apart between the layer.

The filling didn’t spread as easily as I expected but it looks great! I didn’t have chocolate chips so I used ready-made milk chocolate frosting.

I've made this recipe several times now, and it's always a hit! I changed it up last time I made it. I made the brownies in a thinner layer, cut them in half and layered them. Alternating the brownie/peanut butter layers. I then poured the melted chocolate chips over the whole thing and covered the sides like a small layer cake. It looked great. I just renamed it "Double decker Buckeye Brownies ". Again it was a hit! Unfortunately I forget to take a picture of it! Next time...
