ICE-CREAM-CONE CAKE
ICE-CREAM-CONE CAKE
For cake and cones
3 cups all-purpose flour
1 tablespoon baking powder
1 1/2 teaspoons salt
3 sticks (3/4 pound) unsalted butter, softened
1 3/4 cups sugar
4 large eggs at room temperature 30 minutes
1 1/2 teaspoons pure vanilla extract
1 1/2 cups whole milk
7 flat-bottomed wafer cones
For custard buttercream
1 1/2 cups whole milk
9 large egg yolks
3/4 cup sugar
1/4 teaspoon salt
3 1/2 ounces fine-quality bittersweet chocolate (no more than 60% cacao if
marked), chopped
6 sticks (1 1/2 pound) unsalted butter, softened
1 tablespoon pure vanilla extract
2 cups coarsely crushed 2-inch chocolate wafers (28 small cookies)
Equipment: 2 (8- by 2-inch) round cake pans; a small offset spatula; 2 large
pastry bags each fitted with 1/3-inch star tip
Make cake and cones:
Preheat oven to 350°F with racks in upper and lower thirds.. Butter pans. Line
bottoms with parchment, then butter and lightly flour pans.
Sift together flour, baking powder, and salt into a bowl.
Beat butter with sugar using an electric mixer (paddle attachment for a stand
mixer) at medium-high speed until pale and fluffy, about 5 minutes in a stand
mixer or 10 with a handheld. Beat in eggs 1 at a time, then vanilla, and beat
until thoroughly incorporated, about 5 minutes. Reduce speed to low and add
flour mixture in 4 batches alternately with milk, beginning and ending with
flour mixture and mixing until batter is just smooth.
Stand cones, open ends up, in a 12-cup muffin pan and fill cones two-thirds
full with batter. Divide remaining batter between cake pans.
Bake cones in upper third of oven and cakes in lower third until a wooden pick
inserted in center of cake comes out clean, 15 to 22 minutes for cones, 25 to
35 minutes for cakes. Cool cakes 5 minutes in pans on a large rack and transfer
cones to another rack to cool completely. Invert cakes onto rack and cool
completely.
Make buttercream:
Bring milk just to a boil in a medium saucepan. Whisk together yolks, sugar,
and salt in a bowl until combined well, then add milk in a slow stream,
whisking constantly. Transfer to saucepan and cook over medium-low heat,
stirring constantly with a wooden spoon, until custard thickens and registers
175°F on an instant-read thermometer, 5 to 10 minutes (do not let boil). Strain
through a fine-mesh sieve into a metal bowl. Refrigerate, covered, until cold,
at least 1 hour.
Melt chocolate, then cool to warm.
Beat butter with cleaned beaters (whisk attachment if using stand mixer) at
high speed until light and fluffy, about 2 minutes in a stand mixer or 4 with a
handheld. Reduce speed to medium and gradually pour in cold custard. Add
vanilla and increase speed to high, then beat until buttercream is smooth,
about 2 minutes in a stand mixer or 4 with a handheld.
Transfer 1 1/4 cups buttercream to a bowl and stir in warm melted chocolate to
make chocolate buttercream. Transfer about 2 cups vanilla buttercream to
another bowl and fold in crushed wafers to make cookies-and- cream filling.
Assemble cake:
Halve cakes horizontally with a large serrated knife. Put 1 cake layer, cut
side up, on a cake stand or plate and, using offset spatula, spread top with 1
cup cookies-and- cream buttercream. Top with another cake layer, cut side down,
and spread with 1 cup cookies-and- cream buttercream. Top with another cake
layer, cut side up, and spread with remaining cookies-and- cream buttercream.
Top with remaining cake layer, cut side down. Spread side and top of cake with
about 2 1/2 cups vanilla buttercream (total).
Spoon chocolate buttercream and remaining vanilla buttercream into separate
pastry bags.
Halve each cone lengthwise with serrated knife. Attach cones (flat sides) to
side of cake with tops of cones touching. (You will have an extra cone in case
one gets damaged.)
Holding pastry bag filled with vanilla buttercream vertically over cake, pipe
about 2 tablespoons buttercream on top of every other cone (touching top of
cake) to resemble soft-serve ice cream. Pipe chocolate buttercream on top of
remaining cones in same manner.
Cooks' notes:
• Cake and cones can be baked 1 day ahead and kept, tightly wrapped in plastic
wrap, at room temperature.
• To quick-chill custard for vanilla buttercream, set in an ice bath and stir
until cold, about 5 minutes.
• Vanilla buttercream (without chocolate and cookies) can be made 2 days ahead
and chilled, covered. Bring to room temperature and beat before using.
• We used Ateco 824 star tips for our cake. If you have only 1 pastry bag and
tip, pipe vanilla buttercream first, and then chocolate.
