THE BEST CHOCOLATE MOUSSE

Steps:

• Whip 1 cup of the heavy cream to soft peaks in a medium bowl (see Cook's Note). Set aside.
• Add the egg, egg yolks, sugar, espresso powder, vanilla extract, salt and 1 tablespoon water to a medium heatproof bowl and whisk to combine. Set the bowl over a medium saucepan of gently simmering water (do not allow the bowl to touch the water). Whisk constantly until the mixture is pale, hot to the touch and has almost doubled in volume, about 4 to 6 minutes, scraping down the sides of the bowl occasionally with a rubber spatula, if necessary. Remove from the heat and continue whisking until cooled, about 2 minutes.
• Put the chopped chocolate in a medium heatproof bowl and set over the saucepan of gently simmering water (do not allow the bowl to touch the water). Stir occasionally with a rubber spatula until the chocolate is melted and smooth. Remove from the heat and gently stir for about 3 minutes to cool slightly.
• Whisk the egg mixture into the melted chocolate in 3 additions until combined. (The mixture may get very thick.) Using a rubber spatula, gently fold the whipped cream into the chocolate mixture in 3 additions until it is fully incorporated. It is important that the chocolate mixture is not warm to ensure that it combines smoothly with the whipped cream without seizing up.
• Divide the chocolate mousse among four 4-ounce ramekins and chill until firm, about 1 hour.
• Whip the remaining 3/4 cup cold heavy cream to stiff peaks. Top each chocolate mousse with whipped cream and serve. (For a softer texture, allow the ramekins to sit at room temperature while you whip the cream.)

CHOCOLATE BABKA

Steps:

• Make the dough: Sprinkle the yeast over the milk in a liquid measuring cup; add a pinch of sugar and set aside until bubbly, about 7 minutes. Combine the flour, the remaining 1/3 cup sugar, the eggs, yeast mixture, salt, vanilla, nutmeg and lemon zest in a large bowl. Stir with a wooden spoon to combine. Turn the dough out onto a work surface and knead until soft and smooth, about 5 minutes. Knead in the butter in three additions, dusting the dough with flour if it's too sticky. Transfer the dough to a large bowl; cover with plastic wrap and let rise at room temperature, about 1 1/2 hours. Punch down the dough, re-cover with plastic wrap and let rise in the fridge overnight.
• Make the filling: Heat the sugar, heavy cream and salt in a saucepan until scalding. Pour over the bittersweet chocolate chips, butter and vanilla in a bowl. Whisk until smooth and shiny. Let cool to room temperature.
• Make the topping: Whisk the flour, sugar, cocoa powder and salt in a separate bowl; work in the butter with your fingers until the mixture is sandy and chunky. Stir in the mini chocolate chips; set the topping aside.
• Form the loaves: Cut the dough in half with a bench scraper or chef's knife. Using a rolling pin, roll each half into a 12-by-16-inch rectangle. Using an offset spatula, spread the filling on both dough rectangles, all the way to the edges. Starting from a long side, tightly roll each rectangle into a log. Wrap each log in plastic wrap and refrigerate 15 minutes. Unwrap the logs; cut each in half lengthwise with a bench scraper or chef's knife. Twist the halves together a few times, starting from the middle. Coat two 9-by-5-inch loaf pans with cooking spray and line with parchment, then spray the parchment. Place a dough twist snugly in each pan. Cover with plastic wrap and let rise 1 1/2 hours.
• Finish and bake the babka: Preheat the oven to 350 degrees F. Brush each loaf with butter and sprinkle with the topping. Bake until browned, about 45 minutes. Meanwhile, make some simple syrup: Combine the sugar and water in a saucepan; simmer, stirring, until the sugar dissolves. Let cool. Pull the loaves out of the oven and immediately poke a bunch of holes in each with a wooden skewer. Pour 1 1/4 cups simple syrup evenly over the loaves.
• Let sit 10 minutes, then remove the babka from the pans, remove the parchment and let cool completely on a rack.

CHOCOLATE SOUFFLé

Steps:

• Prepare ramekins: Brush ramekin with butter to evenly coat the entire interior, from the bottom of the ramekin to the top of the rim. Add a few tablespoons of sugar to the ramekin, then spin the ramekin around to coat the bottom and the walls, pouring the excess into a mixing bowl. (The sugar coating provides a rough surface for the soufflé to adhere to as it bakes, allowing for a taller rise.) Repeat with other ramekins. Chill until ready to use.
• Preheat the oven to 375 F. Prepare a double boiler: Add enough water to a 1-quart saucepan to fill halfway, and bring to a simmer. Fit a heatproof glass bowl snugly on top of the saucepan, making sure the bottom of the bowl isn't touching the surface of the water. Add chocolate to the bowl and allow it to melt, stirring occasionally. Meanwhile, in a small bowl whisk together the milk and cornstarch. Pour mixture into a small saucepan over low heat and whisk; once the mixture is simmering, continue to whisk until thickened, about 1 minute. When the chocolate has melted, remove the bowl from the saucepan. Slowly add the milk-cornstarch mixture into the melted chocolate, whisking constantly, until it's thoroughly combined. Add egg yolks and whisk until thoroughly combined and shiny. Set aside.
• In a stand mixer fitted with the whisk attachment, add egg whites and a pinch of salt. Starting on low then coming up to medium speed, whip until soft peaks form; then continue whipping as you slowly add the sugar in a steady stream. Once medium peaks form, 1-2 minutes later, turn the motor off and remove whisk. Finish whisking by hand to form medium-stiff peaks. (This prevents the machine from over-whipping, which can cause the soufflé to fall.)
• Use a rubber spatula to stir ⅓ of the whipped whites into the chocolate mixture. Then very gently fold in the rest of the egg whites, being careful not to overmix; the goal is to make sure the egg whites retain their airiness. When the chocolate and egg whites are just mixed, fill each ramekin to the rim. Run the tip of your thumb around the inner rim of the ramekin to wipe off the butter and sugar from the top ¼ inch. This prevents the soufflé from sticking to the rim as it bakes, allowing it to rise straight up.Place ramekins on a rimmed baking sheet lined with parchment paper, then into the oven. Bake until the soufflés have risen about ½-1 inch above the rim, 7-9 minutes.
• When soufflés have fully risen, remove from oven. Dust with powdered sugar, if using. Shape quenelles of unsweetened whipped cream (optional): Pass about a tablespoon of whipped cream back and forth between two spoons, smoothing and shaping it until you have formed an egg-shaped dollop, or "quenelle." Make a small opening in the top of the soufflé and nestle the quenelle into the hole. Serve immediately. (Note: Soufflés will fall quickly as they cool, so work quickly once they are out of the oven!)
