"As mentioned in other reviews, the layers separated (I sprinkled the peanuts first then the peanut butter cups but the chocolate didn't melt enough to adhere the layers) and they were difficult to cut. The taste was wonderful but I didn't like having to hold the layers together while I ate them. Did receive a few compliments on the recipe."

"I made these for my family (a couple of us are die hard brownie and Peanut Butter Cup fans) and took some to work because I had so much. What a big hit! Everybody raved about these and wanted the recipe. I did change it just a little bit because I used what I had on hand at the time. I used Trader Joe's truffle brownie mix, substituted rice crispies with Pumpkin Flax Granola Cereal (healthier then rice crispies?) and used chunky peanut butter instead of creamy. They did fall apart and were hard to cut, but were still a hit and tasted delicious. I actually preferred this over See's California Brittle which is my fave. The taste was a nice combination of brownie, peanut butter and chocolate, not too sweet as a candy bar is. Melts in your mouth (thanks to the load of saturated fat I suppose), but darn good."

"After I refrigerated it, I let it come to room temperature before I cut them. Most of them turned out great, though I too had trouble keeping the top layer on. But wow do these taste good!! I'll make them again as a change, but it's not a favorite."

"Great taste, but I found them very difficult to cut. The chocolate layer kept separating from the bottom layer. Perhaps in step 2 if you would sprinkle the peanuts first and then the peanut butter cups, they would melt and the top chocolate layer would adhere better."

"Made a double batch of these for my son's wedding. Took home an empty plate! They were very well received. Because I have diabetes, I didn't eat any, but others said they tasted like a candy bar! I made these again for work, and I have had to make copies of the recipe to hand out! I think, when I make these again, though, I will try folding the peanut butter cups and peanuts into the brownies before baking. Maybe that will keep them from separating."

"I made yesterday and got nothing but complements and requests for the recipe. I didn't use salted peanuts as my husband is on low sodium diet and I used the unsalted I had on hand. When I make again, I think I will use just 1 cup of peanut butter and 1 1/2 C of chocolate chips instead of 2 C and see if they are really needed. No one complained about the unsalted peanuts. And I used the large pnb cups. Really yummy!"
