This was such a fun cake to make. The mix of chocolate and peanut butter just made me think of childhood...of course licking the spoon did too. My cakes didn't rise as much as I would have liked, so I decided to go with only two tiers instead of the 4. I also decided to add some crushed nuts between the 2 cake layers to give it a bit more crunch. I am really pleased with the end result both in looks and taste!
