Chocolate Caramel Cheesecake Squares

crust:

3 1/2 oz graham crackers, crumbled (1cup)
2 tablespoons sugar
3 tablespoons unsalted butter, melted


filling:
1 teaspoon unflavored gelatin
1/4 cup whole milk
8 oz cream cheese, softened
2 large eggs
3/8 teaspoon salt
1 cup milk caramel (12 1/2 oz) Instructions: Pour 1 can (14 oz.) sweetened condensed milk into top of double-boiler pan; cover. Place over boiling water. Cook over low heat, stirring occasionally, for 40 to 50 minutes, or until thick and light caramel-colored.  Remove from heat. Whisk until smooth.


glaze:
3 oz fine-quality bittersweet chocolate (not unsweetened), coarsely chopped
1/2 stick (1/4 cup) unsalted butter, cut into pieces
2 teaspoons light corn syrup


Make crust: Put oven rack in middle position and preheat oven to 325°F. Line bottom and sides of an 8-inch square baking pan with 2 sheets of foil (crisscrossed), leaving a 2-inch overhang on all sides.


Finely grind crackers with sugar and a pinch of salt in a food processor. With motor running, add butter, blending until combined. Press mixture evenly onto bottom of baking pan. Bake 10 minutes, then cool in pan on a rack 5 minutes.


Make filling: Sprinkle gelatin over milk in a small bowl and let stand 2 minutes to soften. Beat together cream cheese, eggs, salt, and gelatin mixture in a bowl with an electric mixer at medium speed until well combined, about 2 minutes, then stir in milk caramel gently but thoroughly. Pour filling over crust, smoothing top, then bake in a hot water bath (will fit in a 9×13-inch baking pan) in oven until center is just set, about 45 minutes. Cool cheesecake completely in pan on rack, about 2 hours. Chill, covered, at least 6 hours.


Glaze cake within 2 hours of serving: Heat all glaze ingredients in a double boiler or a small metal bowl set over a saucepan of barely simmering water, stirring until smooth, then pour over cheesecake, tilting baking pan to coat top evenly. Chill, uncovered, 30 minutes.


Lift cheesecake from pan using foil overhang and cut into 1-inch squares with a thin knife, wiping off knife after each cut.
