A luscious outrageous cake that will wow your guest! I loved creating this cake and had so much fun making the crepes that I hadn’t done in many years. Years ago when crepes were extremely popular I purchased a Sunbeam M’sieur Crepe maker. To my surprise I found the maker in a cabinet in my basement, unfortunately, it no longer worked so I used an omelet pan to make the crepes. This cake should be started two-three days before you want to serve. The cake is time-consuming yet easy to make. And your guest like mine will be so impressed with the cake because it looks and tastes amazing,
¾ cup plus 2 tablespoons cake flour
¾ cup plus 1 tablespoon all-purpose flour
¼ cup granulated sugar
2 teaspoons kosher salt
4 large eggs
5 large egg yolks
1 stick (8 tablespoons) unsalted butter, melted and cooled slightly
2 cups whole milk
3 tablespoons cognac
1¼ cups confectioners’ sugar
4 cups mascarpone cheese
1/4 coffee liqueur
1/4 cup natural cocoa powder plus 2 tablespoons for topping
1 cup heavy whipping cream
2 tablespoon powder sugar
1. Make the crepe batter: Sift together the cake flour, all-purpose flour, and sugar in a medium bowl. Whisk in the salt. In another medium bowl, whisk together the eggs and egg yolks. Add the egg mixture to the flour mixture and whisk until smooth. In a slow, steady stream, whisk in the butter, then the milk and cognac, until the batter is smooth. Cover the bowl with plastic wrap and refrigerate for 1 hour.
2. Set an 8-inch nonstick skillet over medium-high heat. Gently stir the crêpe batter, then pour ¼ cup of batter into the skillet. Holding the skillet by the handle, tilt and turn the skillet to quickly disperse the batter. Cook the crepe until the underside is golden-brown, about 1½ minutes. Lightly jerk the skillet to loosen the crepe, then flip the crepe over using a spatula, a more vigorous jerking motion or your fingers. Cook on the other side until golden-brown, about 30 seconds, then slide the crepe onto a plate. Top with waxed or parchment paper to prevent crepes from sticking together. Repeat until all of the batter is used (you’ll end up with about 20 crepes total, and will need 18 for the cake). Refrigerate the crepes on a plate until completely chilled, at least 2 hours or overnight.
3. Make the tiramisu filling: Sift the confectioners’ sugar. Add the mascarpone cheese, coffee liquor, and 1/4 cocoa. Combine the mixture at low speed until well combined.
4. Remove the crepes from the refrigerator. Add 1 crepe to the bottom cake plate so it lies flat. Add ¼ cup of the tiramisu filling to the center of the crepe and use a small offset spatula to evenly spread the filling over the crêpe. Repeat with the filling and 17 more crêpes. Refrigerate the leftover filling; you’ll use it to finish the cake. Chill the cake in the refrigerator for at least 2 hours or overnight. Place a metal mixing bowl and metal whisk into the freezer for 10 to 15 minutes.
Place the sugar into the mixing bowl and add the whipping cream. Whisk just until the cream reaches stiff peaks.
Fold whipped cream into remaining tiramisu cream just until combined and no white streaks remain.
Remove the cake from the refrigerator. Spread the remaining tiramisu cream on top and sides of the cake. Add the cocoa powder to a fine-mesh sieve and sprinkle it over the top of the cake. Slice and serve.
