              Prepare the liqueur base. Pour chocolate chips into a jar and add vanilla. Pour in alcohol and mix well. Close the container with a lid and place it in a dark, warm place for 7 days. During this time, shake the jar 2-3 times a day.
              
              
 
              
      
     
              
              
               
              
                  
                  
                   
               
              Prepare the syrup. Pour milk and water into a saucepan. Then add sugar and mix thoroughly. Boil the syrup over low heat, stirring the liquid constantly. Cook for 1 minute. Cool the syrup to room temperature. This will take 40-50 minutes depending on the room temperature.
              
              
 
              
      
     
              
              
               
              
                  
                  
                   
               
              Finish preparing the chocolate liqueur. Pour the cooled syrup into a jar of chocolate liqueur and shake the contents. Store the liquor in a dark place for 14 days. It is necessary to shake the jar daily. After the specified time has passed, pour the liqueur into bottles.
