01 - In a mixing bowl, beat mascarpone cheese, cold heavy cream, powdered sugar, and vanilla extract until the mixture is smooth and thick. Avoid overbeating to maintain structure.
02 - Combine cooled brewed coffee and coffee liqueur in a shallow dish. Stir gently to blend.
03 - Quickly submerge each ladyfinger in the coffee mixture for 1 to 2 seconds per side so they absorb flavor without becoming soggy.
04 - Break the dipped ladyfingers as needed to fit the base of each cup. Arrange 2 halves in the bottom of each of 6 small cups or jars.
05 - Spoon a generous portion of mascarpone cream over the ladyfingers in each cup.
06 - Place a second layer of dipped ladyfingers over the cream, followed by another layer of cream. Smooth the surface using a spatula or spoon.
07 - Use a fine sieve to evenly dust unsweetened cocoa powder over each cup’s surface.
08 - Write spooky messages such as 'RIP' on the chocolate cookies using black food gel or melted dark chocolate.
09 - Insert a decorated cookie vertically into each cup to mimic a gravestone, and add gummy worms or candy bones as desired.
10 - Refrigerate assembled cups for a minimum of 2 hours to set flavors and texture before serving.
