ALMOND-CRUNCH ICE CREAM CAKE

Almond-Crunch Ice Cream Cake image

A frozen almond extravaganza, this ice cream cake was inspired by Good Humor's Toasted Almond Bar: Almond cake layers are brushed with amaretto syrup and have vanilla ice cream and sugared almonds between them; the icing is whipped cream, coated with cake crumbs and more almonds.

Ingredients

2/3 cup blanched whole almonds
2/3 cup cake flour (not self-rising)
1 tablespoon unsalted butter, for pans
6 large eggs, separated
Pinch kosher salt
1 cup granulated sugar
2 teaspoons pure vanilla extract
1 cup blanched sliced almonds
6 tablespoons granulated sugar
1/2 cup granulated sugar
2 tablespoons amaretto or other almond-flavored liqueur, optional
1/2 teaspoon pure almond extract
4 pints vanilla ice cream, slightly softened
3/4 cup cold heavy cream
2 tablespoons confectioners' sugar

Steps:

Cake:Preheat oven to 300 degrees with rack in center. Spread whole almonds in a single layer on a rimmed baking sheet; bake until golden, about 12 to 15 minutes. Transfer sheet to a wire rack; let cool completely.
Pulse whole almonds and cake flour in a food processor until finely ground, about 30 seconds.
Butter two 7-inch round cake pans. Line pans with parchment; butter parchment.
In the bowl of a mixer fitted with the whisk attachment, beat together egg whites and salt on medium speed until soft peaks form. Increase speed to high and gradually add 1/2 cup sugar, beating until stiff and glossy, about 4 minutes. Transfer to a bowl.
Clean mixer bowl and return to mixer fitted with the whisk attachment; beat together egg yolks and vanilla. With mixer on high speed, gradually add remaining 1/2 cup sugar, beating until pale and thick, about 5 minutes.
Fold egg-white mixture into egg-yolk mixture. In three additions, fold in almond mixture. Divide batter evenly between prepared pans, smoothing tops with an offset spatula.
Bake until a tester inserted in centers comes out clean, 18 to 20 minutes. Transfer pans to a wire rack; let cool completely. Turn out cakes and wrap in plastic until ready to use.
Almond Crunch:Increase oven temperature to 325 degrees. In a medium bowl, toss together sliced almonds, granulated sugar, and 2 tablespoons water. Spread almond mixture evenly on a parchment-lined baking sheet. Bake until golden, about 25 minutes. Transfer sheet to a wire rack; let cool completely.
Assembly:Bring granulated sugar and 1/3 cup water to a boil in a small saucepan over medium heat, stirring occasionally. When sugar has dissolved, remove from heat; add amaretto, if using, and almond extract. Let cool completely.
Using a serrated knife, split each cake horizontally into two equal layers.
Cut three 24-by-6-inch strips of parchment. Place strips on top of one another and use to line the sides of a 7-inch springform pan. Generously brush tops of cake layers with syrup. Place a cake layer in prepared pan.
In the chilled bowl of a mixer fitted with the paddle attachment, beat ice cream on medium-low speed until spreadable, about 2 minutes. Spread about 2 cups ice cream over first cake layer. Crumble 1/2 cup almond crunch over ice cream. Top with a second cake layer; transfer to freezer until firm, about 20 minutes. Repeat, spreading 2 cups ice cream and 1/2 cup almond crunch between each layer. Finish with a cake layer. Freeze 1 hour.
Just before serving, whisk cream and confectioners' sugar to medium peaks in a chilled bowl. Remove cake from freezer and release sides of pan. Transfer cake to a serving platter. Tuck parchment strips under perimeter of cake. Frost top and sides of cake with whipped cream; remove parchment strips. Garnish top with remaining almond crunch; serve immediately.
