Dolce mattone is a traditional dessert made by layering buttercream—prepared by whipping butter with eggs and sugar—and rectangular biscuits soaked in coffee. Variations of the recipe include adding cocoa powder to part of the cream or incorporating coffee for extra flavor.

The syrup typically includes liqueurs like rum, vermouth, marsala, brandy, or Sassolino, often combined with coffee to soak the biscuits. Dolce mattone has a rich and creamy texture, balanced by the soaked biscuits, making it a decadent and indulgent dessert.
