Excellent recipe. Light and fluffy cake with a nice thick topping. Very rich tasting (have a lot of milk on hand for your guests to drink). I constantly stirred the contents of the saucepan until everything came to a boil (to avoid cooking the eggs as another Reviewer had that problem) and it worked out fine. One last note warm up the chocolate icing when you are ready to ice the cake it spreads a lot easier. Read More

I think it may be a better idea to add the eggs after the hot wet ingredients are added to the dry ingredients because heating the eggs caused them to cook a little. Read More

If I could give this recipe six stars i would. I made this cake for my finance's birthday and he loved it! The cake was sooo moist and the frosting was absolutely delicious. I did take the advice of adding the eggs after the hot ingredients are added to dry. I used crunchy peanut butter and it was great! I will defiantly make this again Read More

Although I think this cake and frosting were great it was a bit rich. I was hesitant to add oil to the peanut butter and in hindsight I don't think it was needed at all (in fact it really didn't even need the peanut butter to be delicious!) I would make again but definately would leave the oil out of the PB. Thanks for sharing the recipe. Read More
