How to make
Break the biscuits into small pieces and pour the milk over them. Separately, beat the softened butter with the sugar + instant coffee + lemon + egg + walnuts + vanilla.
Combine the two mixtures, knead them well and put them in a cake form. Leave in the refrigerator for 5-6 hours. Remove the cake from the form.
Melt both types of chocolate separately in a water bath and decorate the cake with them.
