"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."
