Coarsely chop 50 g chocolate and 170 g couverture. Melt with 60 g peanut cream in a bowl over a warm water bath. First rinse a mould (approx. 22 x 28 cm) with water, then line it with foil.
Pour in chocolate cream and chill for about 30 minutes until the layer is firm.
Simmer butter, sugar and condensed milk in a small pot until the sugar has dissolved. Pour mixture into a larger bowl. Stir in marshmallow cream, 60 g peanut cream and vanilla extract.
Fold in the peanuts last. Pour the peanut mixture onto the chocolate layer and spread evenly. Place the mould in a cool place for approx. 1 hour until the peanut layer is firm.
Roughly chop the caramel sweets. Simmer the sweets and cream in a pot until a smooth caramel mass is formed. Spread the caramel mass on the peanut layer, chill for about 30 minutes until the caramel is relatively firm.
Coarsely chop 50 g chocolate and 170 g couverture. Melt the chocolate, couverture and remaining peanut cream in a bowl over a warm water bath. Pour the chocolate cream onto the caramel, smooth it down and chill for about 1 hour.
Lift the peanut bar plate out of the mould and cut it into approx. 21 bars.
