Well done--makes me want one!  What is the centre filling?  The middle layer (or filling) seems too deep to be able to support the top, if it is indeed filling. I would love to try this.  Did you use the giant cupcake pan?

Thanks...The center filling is peanut butter, 1 cup and 1c buttercream mixed together...yes giant cake pan...it was soo yummy

Makes me want some with milk but it also makes my teeth hurt just lookin' at all that glorious chocolate and peanut butter...
