To prepare chocolate sauce: in a small saucepan, combine 2/3 cup honey, 1/2 cup cream, cocoa powder and 1/2 teaspoon vanilla. Cook about 5 minutes, stirring constantly, over medium heat, until mixture is well blended and smooth. Set aside; cool to room temperature.
Using a 9-inch springform pan: place parchment paper at bottom and spread a thin layer of honey around inside pan with spatula. Now the lady fingers will stick to the side. Gently press lady fingers, curved side facing out, upright around sides of springform pan. Pack ice cream in even layer into bottom of pan; freeze while preparing peanut butter mixture.
In medium bowl, mix peanut butter, cream cheese, remaining 2/3 cup honey and 1/2 teaspoon vanilla extract until well blended. Whip remaining 1/2 cup cream until soft peaks form; fold into peanut butter mixture. Spread peanut butter mixture over chocolate ice cream layer in pan. Top evenly with cooled chocolate sauce. Freeze for 2 to 3 hours, or until firm, before serving.
