Chocolate Cookie Cake

Melt butter in a saucepan and remove from heat. Add sugar, vanilla, water, eggs and egg yolks (slightly beaten) and drinking chocolate. Return the saucepan to the heat and stir constantly for 3-4 minutes. Crash the biscuits into small pieces and pour into the chocolate mixture. Mix thoroughly and place preferably in an elongated form covered with non stick wax paper. Let cool a little bit and then put in the fridge to set. Take the cake off the form and garnish with ground pistachio or ganache creme. Enjoy it
