Hazelnut-Praline Layer Cake
Cake:
Nonstick spray
2 cups cake flour
1 and 1/2 teaspoons baking powder
1/4 teaspoon baking soda
1/4 teaspoon salt
3/4 cup (11/2 sticks) unsalted butter, at room temperature
1 and 1/4 cups sugar
3 large eggs
3/4 cup buttermilk
1/4 cup Frangelico
1/2 cup roasted, skinned, and finely chopped hazelnuts (roasted in a
350-degree oven for 6 minutes, then chopped; roasted-hazelnut flour
can be substituted)
Praline buttercream:
1 and 1/4 cups sugar
4 large egg whites
Pinch of salt
1/4 teaspoon cream of tartar
3/4 pound (3 sticks) unsalted butter, at room temperature
1/4 cup praline paste or filbert paste (available from New York Cake
& Baking Center, 56 West 22nd Street)
3/4 cup roasted, skinned, and coarsely chopped hazelnuts
Cake: Set a rack in the middle of the oven, and preheat to 375
degrees. Lightly coat two 9-inch cake pans with nonstick vegetable
spray. Line the bottom of each pan with a circle of baking
parchment. Sift the flour, baking powder, baking soda, and salt
together three times. In the bowl of an electric mixer fitted with a
paddle, beat the butter and sugar at high speed for 15 seconds,
until combined. Add the eggs one at a time, beating until each is
incorporated. Continue beating on high until light and fluffy, about
6 minutes more.
With the mixer on its lowest setting, beat in a third of the flour
mixture. Beat in half the buttermilk and all the Frangelico, then
the hazelnuts and another third of the flour mixture. Beat in the
remaining buttermilk and then the remaining flour. Spread the batter
in the prepared pans and bake about 20 to 25 minutes, until cake is
golden brown and the center springs back when lightly pressed and a
cake tester comes out clean. Set the pans on a rack to cool. Turn
out the cakes when cool enough to handle. (If the cakes are
refrigerated for 2 hours at this stage, they will be easier to
handle and frost.)
Praline buttercream: Put 1/2 cup water and the sugar in a small
saucepan fitted with a candy thermometer. Over high heat, bring the
temperature to 240 degrees (soft-ball stage). In the meantime, in
the completely clean and dry bowl of an electric mixer, whisk the
egg whites, salt, and cream of tartar until creamy, foamy, and
barely able to hold very soft peaks. With the mixer running on slow,
carefully drizzle in the hot syrup. Continue to whisk on high speed
until mixture is fluffy, firm, and cooled to room temperature;
gradually beat in the butter and then the praline paste. When the
cakes are cold, trim the tops with a large serrated knife. Split
each cake into two layers. Spread a 1/4-inch layer of the
buttercream between each layer. Frost the outside of the cake with
the remaining buttercream, and then coat the sides of the cake with
the chopped hazelnuts.
Optional: Decorate top of cake with whole hazelnuts, blackberries,
or raspberries to form a row around the edge. |
