In a large mixing bowl, combine the mascarpone cheese, powdered sugar, vanilla extract, and brewed coffee. Mix until smooth and creamy.
Gently fold in the whipped cream until fully incorporated, taking care not to deflate the mixture.
Add the finely crushed ladyfinger cookies to the mixture and fold until evenly mixed.
Using your hands or a cookie scoop, form small balls (about 1 inch in diameter) of the mixture and place them onto a baking sheet lined with parchment paper.
Once all truffles are formed, refrigerate them for at least 1 hour or until firm.
After chilling, roll each truffle in unsweetened cocoa powder until well coated.
Garnish with dark chocolate shavings on top for an elegant finish.
Serve immediately or store in an airtight container in the refrigerator for up to one week.
