"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."

"This is fantastic! I followed the recipe, and it was a big hit. I'll definitely be making this again; it's the perfect dessert size for two adults and a kiddo on a busy week night!"

"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?"
