Put coconut milk, coconut sugar and vanilla sugar in a pot and bring to a boil.

When it starts to boil, add chopped chocolate and stir until all of the chocolate melts. When it boils, pour in the mixture of cornstarch and water, stirring all the time to prevent lumps from forming.

Reduce the heat and cook for about 3 minutes so it can thicken, then set aside.

Break the cookies into small pieces, put them in the cooked chocolate cream and mix a little.

Pour the mixture into a baking tray lined with baking paper and put it in the fridge tolet it harden for a few hours.

Cut into pieces and serve.
