It first seems like a regular chocolate cake but what a difference! Peanut butter is the magic ingredient. It is spread between the cake and the icing.
Excellent cake! It is very rich though, so eat in small portions. I found it was easiest to microwave the peanut butter for 30 seconds and then pour in on. - 09 Apr 2006 (Review from Allrecipes USA and Canada)
This cake caused arguments in my house. "What do you mean you ate the last piece!?" arguments. It was absolutely dense, rich, and delicious. I did make a few changes. I didn't spread the peanut butter layer alone; I was mixing the icing when we got a call and had to leave the house quickly, when we returned, the icing had hardened in the mixer, so I added the peanut butter directly to it and some light cream to bring it to the right consistency and voila! I will definitely make this cake many, many times, especially when I eat the last piece! Try this, you won't be disappointed. - 23 Jan 2006 (Review from Allrecipes USA and Canada)
Very rich and yummy cake! I love peanut butter and chocolate. I've never made a cake where you first cook the butter, cocoa and eggs together on the stove so that was interesting. When I was cooking the frosting mixture, at the last minute the butter separated out and looked gross and greasy, but mixed fine with the powdered sugar. The chocolate frosting is my favorite part! I used Adam's natural peanut butter, which seemed to go well because the rest of the cake is so sweet. I used a whole 16 oz. jar! I also used a 16 oz. bag of powdered sugar for the frosting. A good use of my buttermilk that was really needing to be used! Try this recipe, it's yummy! - 31 Aug 2005 (Review from Allrecipes USA and Canada)
