This tiramisu was a hit with our Test Kitchens staff, who agreed that it's one of the best they've come across. Ladyfingers can be found in the bakery or the frozen-food section of the supermarket. We used soft ladyfingers, which are made to be split.
1 cup cold water
1 (14-ounce) can fat-free sweetened condensed milk
1 (8-ounce) tub frozen reduced-calorie whipped topping, thawed
1 cup hot water
1/2 cup Kahlúa (coffee-flavored liqueur)
1 tablespoon instant espresso or 2 tablespoons instant coffee granules
24 cakelike ladyfingers (2 [3-ounce] packages)
3 tablespoons unsweetened cocoa, divided
How to Make It
Combine first 3 ingredients in a large bowl; stir well with a whisk. Cover surface with plastic wrap; chill 30 minutes or until firm.
Remove plastic wrap, and add cream cheese. Beat with a mixer at medium speed until well-blended. Gently fold in whipped topping.
Combine hot water, Kahlúa, and espresso. Split ladyfingers in half lengthwise. Arrange 16 ladyfinger halves, flat sides down, in a trifle bowl or large glass bowl. Drizzle with 1/2 cup Kahlúa mixture. Spread one-third of pudding mixture evenly over ladyfingers; sprinkle with 1 tablespoon cocoa. Repeat layers, ending with cocoa. Cover and chill at least 8 hours.
