Ingredients
Scale
- For the crust:
- Vegetable oil cooking spray
- 8 plain or almond biscotti, broken into 1-inch pieces (5 to 6 ounces)
- 5 tablespoons unsalted butter, chopped into 1/2-inch pieces, chilled
- 1/4 cup unsweetened cocoa powder
- 1/4 packed cup dark brown sugar
- 1/2 cup raspberry jam or preserves, such as Bonne Maman
- For the filling:
- 1/2 cup semisweet chocolate chips or 1 – 1 oz pouch pre-melted chocolate
- 1 cup mascarpone, at room temperature (8 ounces)
- 1 cup sour cream, at room temperature (8 ounces)
- 5 large eggs, at room temperature
- 1/2 cup granulated sugar
- 1–1/2 teaspoons pure vanilla extract
- Special equipment: One 7-by-10 3/4-inch nonstick metal baking pan
Instructions
- For the crust: Place an oven rack in the middle of the oven and preheat to 325 degrees F.
- Spray the pan with vegetable oil cooking spray. Lay a 6-by-18-inch piece of parchment paper in the pan, allowing the excess paper to overhang the sides. Spray the parchment paper lightly with vegetable oil cooking spray.
- Blend the biscotti, butter, cocoa powder and brown sugar in a food processor until the mixture forms moist crumbs. Firmly press the crumbs onto the bottom of the pan. Bake for 15 minutes. Cool the crust completely, about 25 minutes.
- Spread the jam in an even layer over the crust using a spatula.
- For the filling: Place the chocolate in a small bowl over a saucepan of barely simmering water. Stir occasionally until the chocolate is melted and smooth. Or, if using the pre-melted chocolate in the pouch, just stick the pouch in some hot water for a minute to soften.
- Beat the cheese, sour cream, eggs, granulated sugar and vanilla until smooth, using a whisk, in a medium bowl. Pour the batter over the cooled crust. Randomly spoon the melted chocolate over the batter. Swirl the chocolate into the batter, using the tip of a knife. Bake until light golden and the center of the filling jiggles slightly when the pan is gently shaken, about 40 minutes. Transfer the baking dish to a wire rack and cool for 1 hour. Cover the pan with plastic and refrigerate for at least 6 hours or preferably overnight until firm.
- Run a thin spatula around the sedges of the pan to loosen the filling. Cut the bars into 1 1/2-by-2-inch bars using a damp knife. Serve at room temperature.
Notes
Time above does not include 7 hour set time in refrigerator. You can always substitute regular cream cheese for the mascarpone.
