Baked Alaska with Chocolate Cake and Chocolate Ice Cream

184

Ice cream in a 500-degree oven? As long as it's bundled up in a thick layer of meringue, the outside caramelizes, and the inside (chocolate cake with chocolate ice cream) remains brr-illiantly chilly.

Ingredients

FOR THE CAKES:
2 cups sugar
1 1/3 cups all-purpose flour
1 cup unsweetened Dutch-process cocoa powder
2 teaspoons baking powder
2 teaspoons baking soda
Salt
1 cup vegetable oil
2/3 cup warm water (about 100 degrees)
2 teaspoons pure vanilla extract
6 large eggs, room temperature, separated
FOR ASSEMBLING:
Vegetable oil, cooking spray
6 cups chocolate ice cream (3 pints)
FOR THE MERINGUE:
12 large egg whites, room temperature
3 cups sugar
Pinch of cream of tartar

Directions

Preheat oven to 350 degrees. Spray two 12-by-17-inch rimmed baking sheets with nonstick cooking spray and line with parchment. Make the cakes: Sift 1 1/3 cups sugar, the flour, cocoa powder, baking powder, baking soda, and 1 teaspoon salt into a bowl. Combine oil, water, and vanilla.
Whisk egg yolks with a mixer on medium-high speed until pale and thick, about 5 minutes. With machine running, slowly pour oil mixture into yolks, and then add sugar mixture.
In a clean mixer bowl, whisk egg whites on medium-high speed, gradually adding remaining 2/3 cup sugar, until medium-stiff peaks form. Mix one-third of the whites into cake batter, then gently fold in remaining whites.
Divide batter between the prepared baking sheets, and spread evenly using an offset spatula. Bake until cakes are set and spring back when touched, 18 to 20 minutes. Let cool.
Assemble the baked Alaska: Coat six 11-ounce bowls or ramekins with cooking spray; line with plastic wrap, leaving an overhang. Cut out 6 cake circles to fit in bottoms of bowls (we used a 2 1/2-inch round cookie cutter), and place one in each bowl. Top each with 1/3 cup chocolate ice cream, smoothing surface. Cut out 6 cake circles to fit on top of ice cream (we used a 3 1/2-inch round cookie cutter), and place on ice cream. Freeze until set, about 30 minutes.
Top each cake with 1/3 cup ice cream, smoothing surface. Cut out 6 cake circles to fit on top of ice cream (we used a 4-inch round cookie cutter), and place on ice cream. (This should fit just at the top of the bowl.) Cover assembled cakes with plastic wrap overhang, and freeze for at least 4 hours.
To remove from bowls, open plastic wrap, flip cakes onto a baking sheet, and remove plastic wrap. Freeze cakes while making meringue.
Preheat oven to 500 degrees. Make the meringue: Heat egg whites, sugar, and cream of tartar in a heatproof bowl of a mixer set over a pan of simmering water, whisking often, until sugar dissolves and mixture is warm to the touch, about 2 minutes. Transfer bowl to mixer, and whisk until stiff peaks form, about 10 minutes.
Cover each assembled cake with 1 cup meringue. Bake until meringue is browned, 2 to 3 minutes. Alternatively, hold a small handheld kitchen torch at a 90-degree angle 3 to 4 inches from surface of meringue. Move flame back and forth until browned and caramelized.
