The chocolate spread is melted in a water bath to make liquid (for easier handling it), strained yogurt mix nice to make a smooth mixture. In a rectangular pan (ideally transparent to impress guests) ranks first layer of biscuits soaked in milk. The second layer over the crackers smeared with equal first layer strained milk and pour it on with an even layer of chocolate; back row biscuits, milk and chocolate layer. Complete line with strained yogurt and garnish with chocolate rulers (as fantasy we think). The alternative of decoration is colored or chocolate sprinkles or sprinkling with bitter cocoa. The cake was capped and left for at least 2 hours in the refrigerator. Cut into rectangular or triangular pieces. Immediately prior to fetching sprinkle with plenty of bitter cocoa.
