How to make
Crush the biscuits into large pieces. In a non greased pan, toast the walnuts for a few minutes, then coarsely chop them.
Add them to the biscuits. Heat the milk and add the cocoa, sugar and vanilla.
Pour the mixture over the biscuits and mix.
Pour it into a mold no larger than 70°F (22 cm). Leave the biscuit cake to cool and set for 20 min.
Make the glaze by heating the cream and chocolate.
Pour it on top and garnish with coconut shaving and finely ground walnuts.
Put chocolate cake with biscuits and walnuts in the fridge for two hours and enjoy it!
