Double Chocolate Layer Cheesecake

This cheesecake creates its signature two-tone slice through a clever batter split. Mix the full cream cheese filling, then divide off one cup, stir melted chocolate into that cup, and layer it under the plain batter in the crust. After baking, you get a chocolate base and a vanilla top, all in one slice.

The chocolate cookie crust is essentially obligatory. A store-bought chocolate crumb crust takes this from a project to a 20-minute prep, and the chocolate-on-chocolate edge contrast lines up the flavors nicely.

Semisweet chocolate is the right call. Bittersweet pushes the chocolate layer too dark, milk chocolate goes too sweet. Three squares (3 ounces) melted slightly is the right amount for a single cup of batter.

Forty minutes at 350°F (175°C) is brief for a cheesecake, but the small footprint of a 9-inch pie crust means it bakes faster than a standard springform cheesecake. The center should look almost set (slightly wobbly) when you pull it. The carry-over heat finishes the bake.

Chef Tips

• Room-temperature cream cheese is non-negotiable. Cold cream cheese creates lumps that won’t smooth out.
• Melt the chocolate gently, in a double boiler or 30-second microwave bursts. Scorched chocolate is bitter and unfixable.
• Pour the chocolate layer in slowly so it spreads evenly across the crust, then pour the vanilla over the back of a spoon to keep the layers distinct.
• Chill at least 3 hours, overnight is better. Warm cheesecake slumps and won’t slice cleanly.

Variations

• Top the finished cake with chocolate ganache for a triple-chocolate experience.
• Add a teaspoon of espresso powder to the chocolate layer for deeper chocolate flavor.
• Swirl the two batters together with a knife tip instead of layering for a marbled effect.
