• Crush the wafer cookies into fine crumbs.
• Add the Nutella and mix until a compact, moldable dough forms.

Shape the balls

• Take a small portion of the mixture and flatten it in your hand.
• Place a whole hazelnut and a little Nutella in the centre, then close and roll into a ball.
• Repeat with the remaining mixture.

Chill the balls

• Place the balls on a plate and refrigerate until firm.

Melt the chocolate

• Melt the chocolate gently in a saucepan over low heat.
• Stir in the chopped hazelnuts.

Coat and set

• Let the chocolate set before serving.
