1/2 cup ground coffee beans
1 3/4 cups cold water
1/4 cup Kahlúa (coffee-flavored liqueur), divided
1/2 cup (3 1/2 ounces) mascarpone cheese
1 (8-ounce) block fat-free cream cheese, softened
1/3 cup packed brown sugar
1/4 cup granulated sugar
24 ladyfingers (2 [3-ounce] packages)
2 teaspoons unsweetened cocoa, divided
Assemble drip coffee maker according to manufacturer's directions. Place the ground coffee in the coffee filter or filter basket. Add cold water to coffee maker and brew to make 1 1/2 cups. Combine the brewed coffee and 2 tablespoons Kahlúa in a shallow dish, and cool.
Combine cheeses in a large bowl. Beat at high speed of a mixer until smooth. Add sugars and 2 tablespoons Kahlua, and beat until well-blended.
Split ladyfingers in half lengthwise.
Quickly dip 24 ladyfinger halves, flat sides down, into coffee mixture; place, dipped sides down, in the bottom of an 8-inch square baking dish, slightly overlapping ladyfinger halves. Spread half of cheese mixture over ladyfingers; sprinkle with 1 teaspoon cocoa. Repeat procedure with remaining ladyfinger halves, coffee mixture, cheese mixture, and 1 teaspoon cocoa.
Place 1 toothpick in each corner and 1 in the center of tiramisu (to prevent plastic wrap from sticking to cheese mixture); cover with plastic wrap. Chill 2 hours.
