A simple version of a classic, this Easy Tiramisu is the perfect make-ahead, no-bake, dessert.
In a shallow medium dish, mix together the Kahlua and espresso or coffee. Dip each ladyfinger biscuit into the coffee briefly on both sides, placing enough to cover one layer of the bottom of a 9x13" pan: do not over-soak.
Using a spatula, spread ½ of the mascarpone mixture over the ladyfingers in the pan. Repeat with another layer of the coffee-dipped ladyfingers and finish with spreading the remaining mascarpone mixture on top.
Cover and chill at least 4 hours or overnight. Dust with cocoa powder and serve scoops or slices. Keeps for up to 5 days in the refrigerator.
