Chocolate Mousse Cake

Directions

FOR THE BOTTOM LAYER

Place oven rack in middle position and heat oven to 325 degrees.

Butter the bottom and sides of 9 1/2-inch springform pan. Melt butter, chocolate, and espresso powder in large heatproof bowl set over saucepan filled with 1 inch of barely simmering water, stirring occasionally with a spatula until smooth. Remove from heat and cool mixture slightly, about 5 minutes.  Whisk in vanilla and egg yolks; set aside.

Separate egg yolks from whites.  Beat egg whites and salt at medium speed until frothy, approximately half of a minute.  Add half of the brown sugar and beat until combined, about 15 seconds.  Then add the remaining brown sugar and beat at high speed with stand mixer until soft peaks form.  Scrap down the sides of the bowl lifting the whisk and beat again for 40 seconds.  Using the whisk, fold 1/3 of beaten egg whites into chocolate mixture to lighten the color.  Fold in remaining egg whites until no white streaks remain.  Carefully move batter to prepared springform pan, gently smoothing top with a spatula.

Bake 12-19 minutes.  Bake until cake has risen, is firm around edges, and center has just set but is still soft (center of cake will spring back after pressing gently with finger).

Move cake to wire rack to cool completely, about 1 hour.  Do not remove cake from pan.

FOR MIDDLE WHITE CHOCOLATE LAYER

In a small bowl, sprinkle gelatin over water; let stand at least 5 minutes.  Place white chocolate in medium bowl.  Bring 1/2 cup cream to simmer in small saucepan over medium-high heat.  Remove from heat; add gelatin mixture and stir until fully dissolved.  Pour cream mixture over white chocolate and whisk until chocolate is melted and mixture is smooth, about 30 seconds.  Cool to room temperature, stirring occasionally, 5 to 8 minutes (mixture will thicken slightly).

In clean bowl of stand mixer fitted with whisk attachment, whip remaining cup cream at medium speed until it begins to thicken, about 30 seconds. Increase speed to high and whip until soft peaks form when whisk is lifted, 15 to 60 seconds. Using whisk, fold one-third of whipped cream into white chocolate mixture to lighten. Using rubber spatula, fold remaining whipped cream into white chocolate mixture until no white streaks remain. Spoon white chocolate mousse into pan over bottom layer.  Smooth top with offset spatula.

Return cake to refrigerator and chill until set, at least 2 1/2 hours.

FOR THE TOP LAYER

Mix cocoa powder and hot water in small bowl; set aside.

Melt chocolate in large heatproof bowl set over saucepan filled with 1 inch of barely simmering water, stirring occasionally until smooth. Then remove from heat and cool slightly, 2 to 5 minutes.

Using whisk attachment in stand mixer combine whip cream, granulated sugar, and salt and whisk at medium speed until mixture begins to thicken, about 30 seconds. Increase speed to high and whip until soft peaks form when whisk is lifted, 15 to 60 seconds.

Whisk cocoa powder mixture into melted chocolate until smooth. Using whisk, fold one-third of whipped cream into chocolate mixture to lighten. Using a rubber spatula, fold in remaining whipped cream until no white streaks remain. ¬†Spoon mousse into springform pan over cooled cake and gently tap pan on counter 3 times to remove any large air bubbles; gently smooth top with offset spatula. Wipe inside edge of pan with damp cloth to remove any drips. ¬†Refrigerate cake at least 2 ¬Ĺ hours to firm up.

TO SERVE

If using, garnish top of cake with chocolate curls (Dark Chocolate Curls ) or dust/sprinkle with cocoa power (above).  Run a thin knife between cake and side of springform pan; remove side of pan.  Run cleaned knife along outside of cake to smooth sides. Cut into slices and serve.

Slicing Cold Cake

If cake is refrigerated and being served, run a knife under very hot water and make a clean slice.  Knife may need to be heated twice to cut one slice.  Repeat process until cake is cut.  Cake slices will come out clean looking and may be easier to cut.

Slicing Soft Cake

To create perfectly smooth slices of soft desserts, the best tool is not a knife. It‚Äôs a cheese wire‚ÄĒthe minimal surface area produces less drag for cleaner, neater slices. If you don‚Äôt have a cheese wire, dental floss will work almost as well.
