    Great idea for topping a cake. I used a box mix yellow cake, I ended up using about 1=1/2 cups of creamy peanut butter, dolluped onto the hot cake and gently spread. I started with 1-1/2 pounds of Hershey bars{the giant ones}and only used about 1-1/4 pounds, one pound will be plenty next time....Definitely score the chocolate before it is completely set.....Great bars for a picnic, the chocolate holds everything together to make a cake finger food. I rated it 4 stars because the expense of buying so much chocolate and not needing but half of it is a real downer in my book. This recipe{adjusted} is most definitely a keeper  -  26 Feb 2006  (Review from Allrecipes US | Canada)


    I was initially leary of this recipe because I don't feel that the picture makes it look very appetizing, but then I notices a better pic under the 'related photos' and decided to give it a try and I'm glad I did. It turned out really good, it definately turned out like a homeade version of the Tastycake brand. I used a 9 x 13in. pan instead, I also didn't measure the peanut butter I just spread it on evenly when the cake was right out of the oven, using Reese's brand peanut butter. I melted 5 hershey bars and that was perfect, and it spread smoothly. The cake was very moist. I waited untill the cake was room temperature untill I cut it because the chocolate was to hard right out of the fridge. Next time I think I'll use the 10 x 15inch pan to make this more of a bar type dessert. This recipe's a keeper, will definately make again! Thanks, Rebecca!  -  07 Sep 2007  (Review from Allrecipes US | Canada)


    Do not substitute the chocolate bars with chocolate chips - it hardens too much and makes it difficult to cut. Take this to your next potluck or picnic.  -  07 Apr 2002  (Review from Allrecipes US | Canada)
