In a bowl, add the cottage cheese, condensed milk, vanilla essence, and butter at room temperature, mix everything with a blender until we get a smooth composition, add the previously melted dark chocolate if desired, and incorporate the ingredients.
Fill the desired shapes, level the surface and put in the freezer for 2 hours.
Before removing the bars from the mold, roast the hazelnuts, chop them if desired, and mix them with the melted chocolate and oil.
Securely secure one stick to a knife and dip it into the chocolate, letting the excess chocolate drip off.
Transfer to a baking sheet, repeating the procedure until finished.
