from Flo Braker
1 3/4 cups sifted cake flour
1 teaspoon baking powder
1/4 teaspoon salt
4 ounces ( 1/2 cup) unsalted butter
1 cup sugar
1/2 teaspoon lemon extract
1/2 teaspoon pure almond extract
1 teaspoon vanilla
2 large eggs
1/2 cup milk
1 cup jam of choice, such as apricot, plum or strawberry
Bring all ingredients to room temperature. Adjust rack to lower third of oven; preheat oven to 350°. Grease and flour a 9-inch round springform pan; insert a round of parchment or waxed paper in bottom of pan.
Sift flour, baking powder and salt onto a sheet of waxed paper; set aside.
Using an electric mixer, preferably with paddle attachment, beat the butter in a large bowl at medium speed until it is smooth and creamy.
Maintaining the same speed, add the sugar in a steady stream. When all the sugar is added, stop the machine and scrape the mixture clinging to the sides of the bowl into the center of the bowl. Continue to cream at the same speed for 3 minutes, or until the mixture is light in color and fluffy in appearance. Add the extracts in the final moments of beating the butter and sugar.
With the mixer still on medium speed, add the eggs, one at a time, incorporating each one thoroughly into the mixture before adding the next. When the mixture appears fluffy, reduce the mixer speed to low. Add the flour mixture in three additions alternately with the milk in two additions. Scrape the sides of the bowl occasionally, and mix until smooth after each addition. Spoon the batter evenly into the pan.
Bake for about 40 to 45 minutes, or until a wooden toothpick inserted in the center comes out free of wet batter. Place the pan on a wire rack to cool for 10 minutes. Carefully release the springform and remove the metal ring from around the cake. Cool completely before removing the cake from the metal form.
Using a long serrated knife, cut the cake layer in half horizontally. Set the bottom cake layer on a serving plate and spread the jam over the cut surface. Place the top portion of the cake cut-side down on the jam-covered layer.
To decorate, sift powdered sugar over the top.
