How to make
Break the biscuits into a bowl. Cut the butter on top. Add chocolate, cocoa, walnuts, brown sugar, orange essence and pour hot water. Stir and knead by hand.
Store the mixture in the refrigerator for 1 hour.
Then take a small amount of the mixture, as much as a table tennis ball and shape it like a rock.
Arrange the rocks in a plate and start sticking chocolate flakes on all sides, by trying to keep them even and symmetrical. In the end, you will get very spectacular Sweet Christmas Cones.
Put the Christmas Cones in the fridge overnight to set.
Before serving, sprinkle the festive cones with powdered sugar.
