This was a pretty good cake and the flavors played off of each other nicely. I think the peanut flavor could have been slightly toned down.
I thought this was a faily unique buttercream since it has powdered sugar and you use the food processor.
I made it a two layer cake. Again, doubling the recipe did seem not fill the two pans properly. It seems as if the recipe was made for 1 1/2 inch pans.
