Excellent recipe! Sooo good warm out of the oven with a scoop of vanilla ice cream. This may be a tad sweet for some people, but I thought it was perfect!

These brownies are exactly what I was looking for. I made them according to the recipe with no changes, using real butter. They were not greasy or too sweet. They're very rich and very fudgy, just like a brownie should be. They would be fantastic served with some ice cream and hot fudge.

very good and very rich but not as popular as I thought they'd be at the 2 parties I brought them to (I would cut them smaller to combat the richness next time). I took the advice of others and didn't measure out the chocolate to be swirled on top, just left a little in my batter bowl and then spooned it on top. I'm not sure I'd make them again as I personally wished they had more of a peanut butter flavor. they were fun to make though, I've never made brownies from scratch before and all in all I'd say they turned out very well. thanks for sharing!

These brownies were a huge hit. Easy to make and very good.

DEEEELICIOUS! I cut back the butter by a half stick based on other's reviews. They were sooooo good. Did I mention how good they were? All of them were gone in like 20 minutes. I didn't find them too greasy at all. Make these!

These were extremely rich, even with reduced-fat ingredients. If you're looking for a 50/50 peanut butter and chocolate combination, this isn't it. These were chocolate brownies with just a hint of peanut butter. I'd recommend either doubling or tripling the peanut butter if you're looking for something more peanut buttery. To reduce the fat in these, I made them with reduced fat cream cheese, reduced fat peanut butter, and applesauce in place of the butter. Instead of setting aside a cup of batter for the swirling, I set aside only a few tablespoons, which I still felt was too much. Mine were quite fudgy (to be honest, they were more fudge-like than brownie-like.) I suspect that some people are overcooking them, resulting in more cake-like brownies, since I read several reviews of people leaving them in 15+ minutes longer than the cook time calls for. Don't forget about carry-over cooking. Your brownies will still cook for several minutes after you take them out of the oven, especially when they're in materials that are made to keep heat, like stoneware. I took mine out at 35 minutes, and after they cooled, they were perfect.

These were great! The only thing I changed was the amount of butter, and sugar. I reduced the butter to 3/4 c and the sugar to 1 1/2 c. I think they would have come out too sweet and greasy otherwise. I will definately make these again and again.:)

Thank you for this recipe, they were wonderful. After reading some reviews, I doubled the amount of peanut butter and made sure I only swirled the remaining cup of batter into the peanut butter layer and not all the way through to the bottom. Moist and Rich! I am not trying them with the frosting next time, they are perfect as is.

These were ok but I didn't think the flavor was all that great - I expected more from peanut butter & chocolate. Still, they were good & everyone ate them.

Yummy. I doubled the peanut butter and only put about 1/4cup of the choc batter on top. It turned out great! The peanut butter part pooled a little oil on top but I was able to pat it with a paper towel and it was fine. Might try reduced fat next time to see if it helps. I'll definitely be making this again.

These were really good - I might leave out the chocolate chips next time just because my fiance didn't like them as much but I loved them. I did take other reviewers' advice and didn't reserve the cup of batter. I just layered the brownie mix then the peanut butter mixture and swirled it around and it turned out just fine.

I loved the taste of these brownies, they came out so moist and not too rich! The only problem was with the swirling of the cup of chocolate batter. It definitely would have come out a lot prettier if not for that, one cup of batter was way too much.

Delicious, got raving reviews!

These brownies were delicious. I used real butter not margarine and they were not greasy at all. I also took advice of some others and used less batter on top to swirl. I used only 1/2 cup.

These were good. Nothing spectacular though.

Fantastic!!!! The best brownies ever! I a little over a 1/2 c. of butter as someone said they were greasy. I would have liked 3/4 c. butter. I think I substituted about a 1/2 cup of white wheat flour (or maybe not). Wheat flours surprisingly make fabulous brownies though. The PB was to die for.
