I used two packets of chocolate hazelnut wafers (280g, packs so 560g in total). I layered my 27cm x 18cm lined tin with wafers and what was left went into the mix. With that said add your wafers to a large bowl along with your marshmallows. Give these a mix so the marshmallows don't all stick together. Fire in your jelly sweets, nuts and pour in your melted chocolate. Mix the lot up until fully coated.
