Brownie Baked Alaska

1 . Stage

Preheat the oven to 350 degrees (175 degrees C). Line the bottom of a 9-inch cake pan with parchment and spray the sides with cooking spray.

2 . Stage

Melt butter, semisweet chocolate chips, and unsweetened chocolate in a medium mixing bowl set over a double boiler, stirring frequently. Remove from heat and let cool while working on the next step.

3 . Stage

Combine flour, baking powder, and salt in a small mixing bowl.

4 . Stage

Whisk sugar, eggs, instant coffee, and vanilla together in another bowl until well combined. Pour in the chocolate mixture and stir to combine. Add in the flour mixture and stir until fully incorporated. Pour batter into the cake pan.

5 . Stage

Bake in the preheated oven until edges are set and a toothpick inserted into the middle comes out clean, about 35 minutes. Cool completely in the pan, at least 30 minutes.

6 . Stage

In the meantime, transfer ice cream to the refrigerator to warm for 15 minutes. Line a 9-inch glass mixing bowl with plastic wrap, leaving a few inches of overhang on the sides.

7 . Stage

Remove one of the pints of pistachio ice cream and press into the bottom of the prepared bowl using a small rubber spatula. Smooth into an even layer and freeze for 15 minutes. Repeat the process with both pints of strawberry ice cream, freezing for 15 minutes between each pint.

8 . Stage

Fold the overhanging plastic wrap over the top layer of ice cream. Freeze until solid, 10 hours to overnight.

9 . Stage

Turn brownie out, wrap in plastic wrap, and refrigerate overnight.

10 . Stage

Gently whisk egg whites with superfine sugar and cream of tartar over top of a double boiler until eggs are warm to the touch the sugar has dissolved, about 5 minutes. Pour meringue into the bowl of a stand mixer fitted with a whisk attachment. Whip at a low speed until foamy. Increase speed and beat until stiff, glossy peaks form, 5 to 6 minutes. Stir in vanilla.

11 . Stage

Unwrap chilled brownie and place on a serving tray or cake stand. Grab the plastic wrap overhang and lift the ice cream dome out of the bowl, dunking the bottom of the bowl in warm water to help it release. Place dome flat-side down on top of the brownie.

12 . Stage

Quickly frost the dome with the meringue in a swirl pattern, covering the ice cream completely.

13 . Stage

Toast the meringue using a brulee torch, or broil until browned. Serve immediately.
