I made this cake for my grandson's birthday last year and it was a huge hit.Our whole family loves chocolate and peanut butter together and so it was a perfect choice. My grandson chose it himself from a picture on the Kraft site and has asked for the same cake for his birthday this year. I love to bake and found this recipe simple and the cake turned out as pretty as the picture. In reading over the comments, I think it is important to read directions carefully and also make sure you have the correct ingredients. I had no problem with the frosting at all-it was smooth and creamy, there was plenty to frost and fill the cake, and it was not runny. Also, be sure and choose a good quality cake mix. A recipe can only be as good as the ingredients. I give it a #1 rating.Yum!
