"This was a delicious cake and so easy. Never made any cakes in a crock pot but this was very good."

"I made 1-1/2 recipe because my crock pot is larger than 1-1/2 qts. I used more peanut butter, but it still did not have a strong enough peanut butter taste. We all agreed that this was just okay. I will not make it again."

"Wonderful! Made it 2x now. Once the way the recipe says and once chocolate version. I used nutella in place of the peanut butter and served that version with mint chocolate chip ice cream. very good :)"

"I just LOVED this but it just made a tiny, tiny bit. I think it is made in a little bitty crock pot. Is that correct? What do I need to do to increase the recipe?"

"Very disappointing, odd flavor. No one in my adult family liked it and we all "love" dessert. Was a waste of time and ingredients. I'll stick to the original hot fudge cake recipe."

"Very yummy, except...I forgot to add the sugar to the cocoa mixture. DO NOT leave out the additional sugar (my big boo boo!). Next time I will try adding the chocolate chips, as well. Great dessert~"

"I must have done something wrong....It smelled really good and toothpick came out clean, however when I went to cut into it; it was all soupy on the that the way it's supposed to be? I cooked it in my mini (1qt) crock and it only has 1 setting for 2 hours....maybe that was the problem. I will have to try it again because what we did it was nummy!"

"So easy and so yummy! I love that I can put the kids to bed and my husband and I can enjoy this together. I have a larger crock pot (5 or 6 qts?). I 1 and 1/2 the recipe and it worked great. I also added a small handful of chocolate chips and added them between the two layers. There was a lot of melty chocolate, but that is the point, right? This is definitely on my do-again list :)"

"Could this be baked in an oven?"

"I haven't tried this, so I won't rate it yet, but it sounds delicious. There were comments about not enough peanut butter flavor, so instead of putting chocolate chips on top of the cake like one reviewer suggested, I will try adding peanut butter chips."

"I've made this recipe since it came out in the mag . . . absolutely easy and delicious. Makes just enough for my family of four."

"I only had reduced peanut butter and used it even though it wasn't recommended. DON'T DO IT! The cake didn't set up like a cake at all, just an ooey-gooey mess. It smelled wonderful though! I will try again with FULL flavored PB this time."

"Very tasty! Peanut butter flavor is mild but it's a warm, gooey cake. Who can resist? I realized my crock pot was going to be too large for the recipe so I made it in the oven set at 200-225 degrees for about 2 hours. Topped with whipped cream, it was delicious! Next time, I would add more peanut butter to increase the PB flavor."
