How to cook
On a moderate stove, put a pot with the condensed milk. Once it heats up, add the sour cream and sugar.
Crumble the chocolate into blocks and add them to the rest of the ingredients. Stir the mixture until all the ingredients mix well, being careful not to burn it.
Once the cream becomes homogeneous, remove the pot from the heat and leave it to cool.
Distribute into suitable glasses and sprinkle with coconut flakes. Put them in the fridge overnight and serve the next day.
