These are classic American childhood flavors, combined in a very grown-up way. The cake features a crispy wafer crust topped with layers of peanut butter and chocolate mousse, then finished with a chocolate glaze and a sprinkling of crunchy peanuts. Nothing especially complicated here but the cake does take time to assemble. If you prefer, skip the glaze and top the cake with sweetened whipped cream and chopped peanuts. Use good quality chocolate such as: Lindt, Valrhona or Callebaut.
