Ingredients
- 2 c boiling hot water
 - 3 tbsp instant espresso powder
 - 9 tbsp sugar
 - 3 tbsp Tia Maria coffee liqueur
 - 4 large egg yolks
 - 1/3 c dry Marsala
 - 1 lb mascarpone
 - 1 c heavy cream
 - 36 savoiardi (crisp Italian ladyfingers)
 - unsweetened cocoa powder for dusting
 
Instructions
Combine boiling water, espresso powder, 1T sugar, and Tia Maria in a pie plate. Mix to dissolve sugar, then cool.
Combine egg yolks, Marsala, and remaining 1/2 cup sugar over a simmering double boiler. Beat with a handheld mixer until the mixture has tripled in volume, 5-8 minutes. Remove from heat. Beat in mascarpone until just combined.
Beat cream in a large bowl to stiff peaks.
Fold mascarpone mixture into whipped cream gently but thoroughly.
Dipping both sides of each ladyfinger into the coffee mixture, line the bottom of a 13x9x3 baking pan with 18 ladyfingers in 3 rows, trimming the edges to fit if needed. Spread half of the mascarpone filling on top. Add another layer of coffee-dipped ladyfingers and add smooth over the rest of the mascarpone mixture.
Dust with cocoa, cover with clingfilm, and chill for at least 6 hours.
